Frequently Asked Questions
Everything you need to know about hyaluronic acid lip fillers
In accordance with Swiss legislation (LPTh, ODim/OPTh) and the guidelines of DSAS Vaud, hyaluronic acid injections are medical procedures that must be carried out exclusively by a doctor or a qualified nurse under the direct supervision of a doctor.
Understanding hyaluronic acid lip fillers
What is a hyaluronic acid lip filler?
What is a hyaluronic acid lip filler?
A hyaluronic acid-based lip filler is an injectable gel used to modify the appearance of the lips: to restore volume, hydrate, or better define the contour.
Hyaluronic acid is a substance naturally present in the skin, which explains why it is now one of the most widely used products for "natural" lip augmentation. Lip fillers fall into the category of medical devices and must be injected by a trained healthcare professional.
What are the purposes of hyaluronic acid injections in the lips?
What are the purposes of hyaluronic acid injections in the lips?
Hyaluronic acid injections in the lips are primarily used to:
- To increase or restore the volume of lips that have thinned over time.
- Better define the contour (hem) of the lips, for example to redraw the Cupid's bow.
- To rebalance an asymmetry between the upper and lower lip.
- Improve hydration and surface appearance when lips look dry or wrinkled.
The most common goal is to achieve lips that are more harmonious with the rest of the face, with a result that remains natural.
What is the composition of the hyaluronic acid fillers you use for lips?
What is the composition of the hyaluronic acid fillers you use for lips?
In practice, a lip filler contains:
- Synthetic cross-linked (stabilized) hyaluronic acid, designed to remain in tissues for several months.
- A physiological solution (water, salts) to make the product injectable.
It contains no animal collagen or liquid silicone. The technical characteristics (concentration, degree of cross-linking, viscosity) vary depending on the brand and range, allowing the product to be adapted to the needs of the lip: more supple for hydration or more structured to define the contour, for example.
How do hyaluronic acid fillers work in the lips in terms of skin and volume?
How do hyaluronic acid fillers work in the lips in terms of skin and volume?
Hyaluronic acid fillers act through three main mechanisms:
- Immediate volume
The gel physically occupies space and reshapes the lips from the inside out.
- Water retention and hydration
Hyaluronic acid can bind up to 1,000 times its weight in water, which helps lips stay hydrated and plump.
- Longer-term tissue effects
Some studies suggest a possible positive impact on tissue quality, but this effect remains variable and cannot be guaranteed. Fillers primarily work by providing immediate volume and improving lip hydration.
The body gradually breaks down HA via natural enzymes (hyaluronidases), and the effect slowly fades.
Are hyaluronic acid lip fillers permanent or reversible?
Are hyaluronic acid lip fillers permanent or reversible?
Hyaluronic acid-based lip fillers are not permanent.
- Most lip fillers last approximately 6 to 12 months, although some people retain a visible result for up to 18 months depending on the product, metabolism and lifestyle.
- The gel is slowly metabolized, which means that volume and definition decrease gradually, not overnight.
They are also reversible If necessary, AH can be dissolved by an enzyme called hyaluronidasewhich degrades the filler in a matter of hours to a few days.
Can I have lip fillers removed or corrected if I'm not happy with the result?
Can I have lip fillers removed or corrected if I'm not happy with the result?
Yes. Because they are composed of hyaluronic acid, most lip fillers can be dissolved by hyaluronidase:
Hyaluronidase is injected into the treated area to break down the hyaluronic acid gel into smaller molecules that your body naturally eliminates.
It can be used on demand (if you are not satisfied with the shape) or in an emergency in case of a complication such as a vascular occlusion.
It should be noted that the dissolution process itself can cause temporary swelling, bruising or sensitivity, and sometimes requires several sessions.
Are all lip filler treatments equal or are there different techniques/products?
Are all lip filler treatments equal or are there different techniques/products?
No – there are significant differences at the level of:
- About the product: Gel flexibility/firmness, concentration, crosslinking technology, presence of lidocaine, and specific indication (some fillers are formulated only for lips).
- Injection techniqueneedle vs cannula, injection depth, design (linear, micro-drops) and aesthetic philosophy.
- From the treatment plan: simple hydration vs more marked increase, treatment or not of perioral wrinkles, number of sessions to build the result gradually.
These differences affect comfort, swelling, the duration of the result, and the natural appearance of the outcome. Choosing an experienced medical injector is more important than the specific brand of product.
Is it worth asking what type of hyaluronic acid is being used for my lips?
Is it worth asking what type of hyaluronic acid is being used for my lips?
Yes, it's perfectly legitimate to ask:
- The exact brand and product used
- If there is FDA/EC authorization for facial or labial use
- If the product contains lidocaine and the approximate concentration of Hyaluronic Acid
Regulatory agencies insist that patients must know precisely what is being injected, and that only regulated medical fillers should be used.
Asking these questions helps to avoid unregulated or counterfeit products.
Combination with other treatments
Can I combine hyaluronic acid lip fillers with botulinum toxin or other cosmetic treatments?
Can I combine hyaluronic acid lip fillers with botulinum toxin or other cosmetic treatments?
Yes, combination treatments are very common:
- Botulinum toxin can be injected around the lips (lip flip, chin, depressor muscles) to complement fillers by relaxing overactive muscles responsible for wrinkles or that pull the lips downwards.
- Skin boosters or mesotherapy can be used on neighboring areas (perioral skin) for improved hydration and texture.
They are not usually injected at exactly the same points on the same day, but can be integrated into an overall treatment plan.
What is the difference between a hyaluronic acid lip treatment and a botulinum toxin “lip flip”?
What is the difference between a hyaluronic acid lip treatment and a botulinum toxin “lip flip”?
Hyaluronic acid lip fillers:
- They add volume and structure
- Improves shape, contours and hydration
- Provide results lasting on average 6 to 12 months
Lip flip (botulinum toxin):
- Uses very small doses of toxin, injected into certain muscles to relax them, which causes the upper lip to slightly "roll" outwards, giving a more visible lip effect without adding volume.
- The effects last 3 to 4 months.
Often, a small amount of filler combined with a moderate lip flip gives a very balanced and natural result.
What is the difference between hyaluronic acid lip fillers, lipofilling, and lip implants?
What is the difference between hyaluronic acid lip fillers, lipofilling, and lip implants?
Hyaluronic acid fillers:
- Minimally invasive procedure, performed in the office, reversible with hyaluronidase.
- Predictable and adjustable result
Lipofilling (fat transfer)
- Uses your own fat, harvested by liposuction and then injected into the lips.
- Potentially more durable but less predictable, with a risk of nodules and partial resorption.
Lip implants
- Surgical placement of permanent synthetic implants.
- Higher risk of long-term problems (migration, visibility, infection) and more difficult withdrawal.
For most patients, hyaluronic acid fillers are the safest, most flexible, and most reversible option.
How do lip fillers differ from mesotherapy or skin boosters?
How do lip fillers differ from mesotherapy or skin boosters?
Hyaluronic acid fillers for lips:
- Cross-linked hyaluronic acid, in gel form, injected deeper to add volume and structure the lips.
Mesotherapy
- A series of superficial micro-injections of a mixture of vitamins, amino acids, small amounts of HA and other substances, primarily targeting skin quality, not volume.
Injectable skin boosters / moisturizers
- They use a more stabilized but less dense HA, injected on the surface to improve hydration, texture and radiance, without major modification of the contour.
At the level of the lips, fillers are mainly used for shape and volume, while mesotherapy/skin boosters target fine lines and texture around the mouth.
Can I get hyaluronic acid fillers if I already have a previous permanent filler in my lips?
Can I get hyaluronic acid fillers if I already have a previous permanent filler in my lips?
Permanent fillers (e.g. silicone, some older PMMA-based products) are far more problematic and are no longer recommended for the lip area due to the risk of long-term complications.
If you already have a permanent filler, adding a hyaluronic acid filler may increase the risk of lumps, inflammation, or deformity.
In some cases, surgical removal of the permanent product or imaging (ultrasound) may be necessary before any further treatment.
It is essential to inform your doctor about any previous fillers, even if they are several years old.
Indications & people concerned
For whom are hyaluronic acid lip fillers suitable?
For whom are hyaluronic acid lip fillers suitable?
Lip fillers are suitable for adults who wish to:
- To augment naturally thin lips
- Restore the volume lost with age
- Improve the symmetry, definition, or Cupid's bow
- Reduce vertical lines and improve the overall texture of the lips
Ideal patients are in good general health, have realistic expectations, and understand that the result is temporary and requires maintenance.
Clinical reviews confirm that HA fillers are effective and generally safe for facial rejuvenation in well-selected patients.
An individual medical evaluation is necessary to confirm that this treatment is suitable for your situation.
At what age can hyaluronic acid injections in the lips be considered?
At what age can hyaluronic acid injections in the lips be considered?
Most doctors recommend that lip injections be done only in adulthood, when facial features are stable and the person fully understands the implications of the procedure.
In practice, many practitioners set a limit of around 18 years or older, or even more.
The most important criterion is not just age, but:
- the maturity of the person,
- the stability of facial features,
- the absence of external pressure (social networks, social circle…),
- a real personal discomfort related to the lips (volume, contour, asymmetry).
For those under 18, hyaluronic acid injections in the lips are generally discouraged and should remain very exceptional cases, after thorough discussion and medical advice.
Is there a maximum amount of hyaluronic acid that can be injected into the lips?
Is there a maximum amount of hyaluronic acid that can be injected into the lips?
Yes, there are practical and safety limitations:
- For a first session, most practitioners inject 0,5 to 1,0 mL in total. Beyond this, the risk of an unnatural result, excessive pressure, marked swelling, and complications increases.
- Excess volume can compromise vascularization and lead to deformations or migration of the filler in the long term.
A prudent doctor will respect the anatomy of your lips and, if you desire a more significant change, will favour gradual augmentations over several sessions rather than a large volume all at once.
Can lip fillers correct asymmetry or a "gummy smile"?
Can lip fillers correct asymmetry or a "gummy smile"?
Yes, to some extent.
Asymmetry: Hyaluronic acid fillers can help correct subtle imbalances between the sides or between the upper and lower lip.
Gummy smile: in mild forms, it can sometimes be reduced by adding volume to the upper lip and/or with a small amount of botulinum toxin in the lip elevator muscles ("lip flip").
The doctor will assess your smile and dental occlusion to determine what is realistic.
Results, duration
& interview
How long does it take to see the first results of hyaluronic acid injections in the lips?
How long does it take to see the first results of hyaluronic acid injections in the lips?
You will see an immediate change as soon as the injection is finished, but the final result takes some time to stabilize:
- Days 0–2 : the lips appear fuller but may look asymmetrical or very swollen.
- Days 3–7 : the swelling and bruising gradually decrease.
- After 2 weeks : the result is generally stable and close to the final rendering.
Many doctors recommend a check-up 2 to 4 weeks after the injection.
Should I plan for a rest period after a hyaluronic acid injection in the lips?
Should I plan for a rest period after a hyaluronic acid injection in the lips?
Most people can resume their daily activities immediately:
- You can usually work, drive and do light tasks all in the same day.
- However, expect visible swelling and possibly bruising for a few days, which may encourage you to avoid large social events during this period.
Strenuous physical activities, exposure to heat, and pressure on the lips should be temporarily limited.
What care should I apply to my lips in the days following hyaluronic acid injections?
What care should I apply to my lips in the days following hyaluronic acid injections?
General advice:
- Apply cold packs intermittently during the first 24 hours.
- Keep your lips clean and well-hydrated with a neutral balm.
- Do not pick at any dead skin or scabs around the injection points.
- Continue to avoid tobacco, excessive alcohol, saunas and intense sunlight for a few days.
If in doubt, send photos or request a check visit.
When can I resume sports or return to the gym after having hyaluronic acid lip fillers?
When can I resume sports or return to the gym after having hyaluronic acid lip fillers?
Avoid intense physical exertion, hot yoga and heavy weight training for 24 to 48 hours.
Gentle walking is permitted and may even promote traffic flow.
Exercise increases blood flow and pressure, which can exacerbate swelling and bruising in the early stages.
Can I fly or travel shortly after having hyaluronic acid injections in my lips?
Can I fly or travel shortly after having hyaluronic acid injections in my lips?
Air travel is generally safe after lip fillers are applied. Changes in cabin pressure usually do not affect the filler.
However, as it is easier to manage any potential complications close to the clinic, many practitioners prefer that you remain nearby for 24 to 48 hours after the injections.
If you are planning a trip, schedule your treatment early enough to allow for follow-up.
How long do the effects of hyaluronic acid lip fillers last on average?
How long do the effects of hyaluronic acid lip fillers last on average?
Most of the time, hyaluronic acid-based lip fillers last approximately 6 to 12 months, with some variability.
The duration depends on:
- The nature and cross-linking of the filler
- Your metabolism, tobacco use, and lifestyle
- The degree of lip movement (speech, sports, etc.)
- The initial quantity injected
Can the results of a hyaluronic acid lip treatment look natural?
Can the results of a hyaluronic acid lip treatment look natural?
When the treatment is done correctly, the result should be harmonious and natural:
- Modern hyaluronic acid fillers are designed to integrate smoothly with tissues.
- Current trends and the retreat of some celebrities from "over-filled" lips clearly point towards a subtle and balanced augmentation, rather than extreme volumes.
The natural appearance depends mainly on the aesthetic sense and experience of the doctor performing the injection.
During the consultation, you can show reference photos and specify that you want a "very natural" result.
What volume of product is generally injected during a first session of lip fillers?
What volume of product is generally injected during a first session of lip fillers?
For reasons of safety and naturalness, most doctors use:
- 0,5 mL for a very discreet change or for the first time
- Up to 1,0 mL for a visible but natural-looking increase
Larger volumes are generally reserved for fractional treatments, not for a first session, in order to avoid excessive projection and excessive swelling.
Can I request a very subtle result, for example just rehydrating the lips without increasing their volume much?
Can I request a very subtle result, for example just rehydrating the lips without increasing their volume much?
Yes. The treatment can be geared more towards hydration, texture and contour than towards increasing size:
- Softer and less dense fillers, similar to skin boosters, improve smoothness and shine with a very limited volumizing effect.
Clearly state that you want an "almost invisible" improvement, and the doctor will adjust the product, technique, and volume.
What happens when hyaluronic acid lip fillers are absorbed?
What happens when hyaluronic acid lip fillers are absorbed?
As your body metabolizes hyaluronic acid:
- The lips gradually return to their original size and shape.
Over time, hyaluronic acid is naturally broken down and the lips gradually return to their original appearance. Some patients report an impression of improved texture, but this effect is neither systematic nor guaranteed.
How often do hyaluronic acid injections need to be repeated to maintain the results on the lips?
How often do hyaluronic acid injections need to be repeated to maintain the results on the lips?
Most patients repeat the treatment every 6 to 12 months to maintain their results, depending on:
- Their metabolism and lifestyle
- Of the product used
- Regarding the intensity of the desired effect, clinical data and practical experience consistently show a typical longevity within this range.
Procedure for a hyaluronic acid lip injection session
How can I best prepare before a hyaluronic acid lip filler session?
How can I best prepare before a hyaluronic acid lip filler session?
Before a lip injection session, it is advisable to come with clean skin, without makeup on or around the mouth (no lipstick, pencil or foundation).
In the days leading up to the event, many doctors recommend avoiding alcohol and, if possible, certain medications that promote bruising (aspirin, anti-inflammatories, certain omega-3 type supplements), but only after discussing it with your doctor.
If you are prone to cold sores, mention it: preventative treatment can sometimes be offered. Arriving rested, well-hydrated, and with your questions written down will also help you get the most out of your consultation.
What happens during the first consultation for lip injections?
What happens during the first consultation for lip injections?
The first consultation is primarily used to assess your health: medical history, current treatments, allergies, possible contraindications (pregnancy, breastfeeding, autoimmune diseases, local infection, anticoagulants, etc.).
The doctor then analyzes the shape of your lips, the balance of your face, and your expectations (volume, hydration, contour, correction of asymmetry, etc.). She explains the different options, the limitations of the treatment, the possible risks, and the duration of the results.
In the end, a personalized treatment plan and a quote are offered to you, without any obligation to carry out the injections on the same day.
How does a lip injection session proceed, step by step?
How does a lip injection session proceed, step by step?
Although the protocols vary slightly, a typical session unfolds as follows:
- Cleaning and disinfecting the lips and surrounding skin.
- Possible application of an anesthetic cream or additional local anesthetic for added comfort.
- Marking of key injection points.
- Injection of the filler with very fine needles or a flexible cannula, layer by layer, controlling the symmetry and volume from different angles.
- Gentle filler shaping.
- Application of a cold pack to limit swelling.
- Providing post-treatment instructions and arranging a possible follow-up appointment.
How long does an appointment for hyaluronic acid lip injections last?
How long does an appointment for hyaluronic acid lip injections last?
- The consultation + treatment often lasts 30 to 60 minutes, depending on the complexity and whether or not it is a first session.
- The injection phase itself usually lasts 10 to 20 minutes.
More time is spent on planning, consent, and explanations than on the injections themselves.
Are hyaluronic acid injections in the lips painful?
Are hyaluronic acid injections in the lips painful?
Most patients describe the sensation as unpleasant but bearable, comparable to a series of small pricks or pressures.
An anesthetic cream is frequently used, which significantly reduces pain without compromising safety or effectiveness.
How many lip filler sessions are typically needed for optimal results?
How many lip filler sessions are typically needed for optimal results?
It all depends on your base and the objective you are seeking:
- Many patients achieve the desired result in a single session.
- For more significant transformations or marked asymmetries, the doctor may suggest 2 to 3 sessions spaced several weeks apart, to build volume gradually, in a safer and more natural way.
As a general rule, a cautious and gradual approach yields more harmonious results than a radical transformation all at once.
What brands or ranges of hyaluronic acid do you use to treat lips?
What brands or ranges of hyaluronic acid do you use to treat lips?
For the lips, doctors use hyaluronic acid fillers specifically designed for the lip area, chosen for their flexibility, moisturizing capacity, and safety profile.
These are products from recognized brands, CE marked or compliant with European or Swiss requirements, from laboratories specializing in aesthetic medicine.
Depending on your needs, the doctor will choose:
- very flexible gels to work on hydration and fine lines,
- or slightly more structuring gels to redefine the contour or add more volume.
Do not hesitate to ask during the consultation which specific product will be injected, which range it is, its estimated duration and its history of use.
Safety, side effects and contraindications
Who should avoid lip fillers - what are the main contraindications?
Who should avoid lip fillers - what are the main contraindications?
Lip fillers are not recommended in the following situations:
Pregnancy or breastfeeding: security data is insufficient, so most experts recommend avoiding fillers during this period.
Active infection or inflammation in or around the lips, including herpes (“cold sore”), acne, cuts or dental abscess.
Known allergy or hypersensitivity to hyaluronic acid, lidocaine or other components of the filler.
Uncontrolled autoimmune or systemic disease, or severe general pathology (case-by-case assessment with your doctor).
Coagulation disorders or taking strong anticoagulants that cannot be safely stopped (to be discussed with your prescriber).
History of severe reaction to fillers, for example delayed inflammatory nodules that have required prolonged treatment.
The doctor will assess your health and confirm whether this treatment can be carried out safely.
What is not recommended immediately after a hyaluronic acid lip treatment?
What is not recommended immediately after a hyaluronic acid lip treatment?
For the first 24 to 48 hours, avoid:
- Alcohol and tobacco - they can increase swelling, bruising and slow down healing.
- Intense sport and activities that greatly accelerate heart rate or blood pressure.
- Significant heat (sauna, hammam, very hot baths, intense sun, UV cabins).
- Applying firm pressure or massaging the lips, unless specifically instructed by the doctor.
Can I reapply lipstick or lip gloss immediately after my lip injections?
Can I reapply lipstick or lip gloss immediately after my lip injections?
It is advisable to avoid lipstick and lip makeup for at least 6 hours, or even until the next day, to reduce the risk of infection and friction.
- A clean, neutral lip balm is generally acceptable earlier. There are no strict restrictions on balm, as long as the area is clean and you are comfortable.
The doctor will specify the instructions according to her protocol.
Can I smoke or vape after a hyaluronic acid lip treatment?
Can I smoke or vape after a hyaluronic acid lip treatment?
Ideally, do not smoke or vape for at least 24 to 48 hours, and longer if possible:
- Tobacco and vaping can impair microcirculation, increase swelling and bruising, and slow down healing.
- The act of "pinching" the lips also exerts pressure on recently injected tissues.
This is an ideal time to consider reducing or stopping smoking, with support if needed.
Can I get lip injections if I am pregnant or breastfeeding?
Can I get lip injections if I am pregnant or breastfeeding?
In practice, the answer is no.
There are no controlled studies demonstrating the safety of fillers during pregnancy or breastfeeding.
Professional recommendations and most clinics therefore advise postponing any filler treatment until after pregnancy and breastfeeding.
This is a precautionary measure to protect both mother and child. Always discuss your personal situation with a doctor before making any decision.
What are the possible side effects and complications of hyaluronic acid lip fillers?
What are the possible side effects and complications of hyaluronic acid lip fillers?
The common effects, generally mild and temporary, are:
- Swelling (reported in 70–80% of cases)
- Sensitivity or pain at the injection sites
- Firmness or small bumps
- Bruises and redness
They usually disappear within a few days to two weeks.
The rarer but more serious risks include:
- Infection or abscess
- Delayed inflammatory nodules or granulomas (rare)
- Reactivation of cold sores in predisposed individuals
- Vascular occlusion - when the filler obstructs or compresses a blood vessel, which can lead to skin lesions, scarring, or very rarely visual impairment.
Large clinical series show that serious complications remain rare (around 1–2% of treatments in some analyses), but they do exist and must be recognized and treated quickly.
The doctor will explain the potential risks and assess your individual factors with you.
How long does lip swelling usually last after injections?
How long does lip swelling usually last after injections?
- First 24 to 48 hours: swelling is at its maximum.
- Days 3 to 5: swelling and sensitivity decrease significantly.
- Days 7 to 14: most of the swelling has disappeared and the shape is approaching the final result.
Cold packs (wrapped ice), a slightly elevated sleeping position, and avoiding heat help to limit swelling.
What signs might suggest rejection or poor tolerance of a hyaluronic acid filler in the lips?
What signs might suggest rejection or poor tolerance of a hyaluronic acid filler in the lips?
"Rejection" in the sense of a transplant is very rare with hyaluronic acid, but immune or inflammatory reactions can occur after treatment. Warning signs include:
- Persistent or increasing redness, heat, swelling, or pain beyond the usual healing phase
- Hard nodules or lumps that appear or increase in size over time
- Changes in skin color or texture around the area
These manifestations may correspond to delayed hypersensitivity, infection, granuloma or biofilm rather than classic "rejection".
If you experience such symptoms, contact your clinic immediately for an examination and possible treatment (antibiotics, corticosteroids, and/or hyaluronidase). If in doubt, prompt medical advice is essential to determine the appropriate course of action.
What symptoms should prompt me to contact the clinic urgently after lip injections?
What symptoms should prompt me to contact the clinic urgently after lip injections?
You should seek urgent medical attention on the same day if you notice:
- Sudden and intense pain in or around the lips during or after the injection
- A pallor, whiteness, bluish or mottled tint to the skin of the lips or around
- Swelling, firmness, or bruising that increases rapidly in a specific area
- Visual disturbances, severe headache, or dizziness
These signs may indicate a vascular occlusion or another serious complication requiring immediate treatment with high-dose hyaluronidase and other measures to preserve tissue and vision. Immediate medical attention is necessary if you experience any unusual symptoms after the injection.
Can hyaluronic acid lip fillers migrate or create small bumps?
Can hyaluronic acid lip fillers migrate or create small bumps?
Yes, although good technique greatly reduces this risk:
- Small irregularities or bumps immediately after treatment are common, often due to swelling or small accumulations of filler. They generally subside spontaneously.
- True migration (the filler moving outside the injected area) can occur, especially in cases of excessive volume, repeated treatments in the same area, or injections that are too superficial.
Treatment ranges from simple in-office massage to the use of hyaluronidase to dissolve the product if necessary.
Do hyaluronic acid injections in the lips increase the risk of a herpes (cold sore) outbreak?
Do hyaluronic acid injections in the lips increase the risk of a herpes (cold sore) outbreak?
Yes, any trauma to the lips, including injections, can reactivate the herpes simplex virus (HSV-1) in carriers. Studies on lip augmentation mention herpes as a recognized but uncommon side effect.
If you have a history of cold sores, please mention it: your doctor may prescribe preventative antiviral treatment a few days before and after the session.
Is it common to experience bruising after hyaluronic acid lip treatment?
Is it common to experience bruising after hyaluronic acid lip treatment?
Bruising (ecchymosis) is very common, especially in an area as vascularized as the lips:
- Meta-analyses report bruising in approximately 30 to 40% of cases after lip fillers.
- Bruises usually appear in 1 to 2 days and disappear in about ten days.
Avoiding alcohol and non-essential blood thinners before the session, and applying cold afterwards, helps to limit their impact.
