BOTULINUM TOXIN FOREHEAD WRINKLES

Dernière mise à jour : 17 July 2026

What are forehead wrinkles ?

Forehead wrinkles are horizontal lines that gradually appear as a result of repeated contractions of the frontalis muscle, combined with natural skin ageing. Over time, declining levels of collagen, elastin and hyaluronic acid encourage these wrinkles to become established, until they remain visible even when the face is at rest. They can make the face look tired or older. In aesthetic medicine, botulinum toxin is the standard treatment for forehead wrinkles, temporarily reducing frontalis muscle activity while preserving natural expressions.
Hyaluronic acid injections to fill forehead wrinkles are rarely indicated, as their effectiveness in this area is limited and their use remains exceptional.
Topical skincare can also help preserve skin quality. Anti-wrinkle creams containing hyaluronic acid, vitamin C or other antioxidants promote skin hydration, stimulate collagen production and help slow the skin ageing process.

Why do forehead wrinkles
appear ?

Forehead wrinkles develop through the action of the frontalis muscle.
Facial muscles are attached to the skin. As expressions are repeated, the muscles (the right and left frontalis muscles) become increasingly powerful and pull on the skin when the eyebrows are raised. These are known as expression lines.
The skin, repeatedly subjected to these movements and weakened by declining hyaluronic acid and collagen levels (an inevitable process over time), becomes damaged and static wrinkles (wrinkles present at rest) appear. These are known as resting wrinkles.
The age at which these wrinkles appear varies from person to person. It depends in particular on initial muscle tone, which is partly genetically determined, and the degree of facial expressiveness. This explains why these wrinkles can sometimes appear very early, even before the age of 18.

Severity stages of forehead wrinkles

Forehead wrinkles progress through stages, from fine superficial lines to more visible, deeper wrinkles.
Personalised care introduced early can slow this progression and help the forehead retain a smooth, rejuvenated appearance for longer.

Stage 1 : fine, superficial wrinkles

Description
At this stage, forehead wrinkles are slight and shallow. They are visible only when the face moves, for example when expressing surprise or concentration. They disappear at rest.

Recommended treatment
Preventative skincare such as moisturisers and retinol serums, along with gentle aesthetic treatments such as mild chemical peels or microdermabrasion.

Stage 2 : moderate wrinkles

Description 
Wrinkles become more visible and begin to appear even when the face is at rest, indicating a loss of skin elasticity. They are deeper than those seen in the first stage.

Recommended treatment
Botulinum toxin injections are indicated and treat wrinkles effectively.

Stage 3 : pronounced wrinkles

Description
Forehead wrinkles are now deep and cover a larger area of the forehead. The skin may look permanently creased and wrinkled.
The skin has lost a significant amount of its elasticity and thickness.

Recommended treatment  
Combined treatments, involving botulinum toxin and hyaluronic acid injections, may be needed to achieve optimal results.

Stage 4 : very deep wrinkles and deep folds

Description
At this advanced stage, wrinkles are extremely deep and may be accompanied by pronounced skin folds, giving the forehead a severely wrinkled appearance. The skin has lost elasticity and collagen levels have fallen significantly.

Recommended treatment  
Combined procedures involving botulinum toxin and hyaluronic acid injections and ablative laser sessions are required if the aim is to eliminate wrinkles.

How can wrinkles be prevented
on the forehead ? How can you massage the
forehead to remove wrinkles ?

Increasing numbers of women turn to facial exercises in the hope of reducing forehead wrinkles and slowing their progression. One frequently recommended exercise involves placing three fingers at eyebrow level and pulling them slightly downwards while trying to raise the eyebrows. This exercise should be repeated ten times a day for five seconds.
Although facial exercises may help tone certain muscles and improve awareness of facial expressions, their effectiveness on established wrinkles remains limited. They are more a natural maintenance method than a true anti-wrinkle treatment. Creams do not erase wrinkles either : their main role is to maintain good skin hydration and support skin quality.

How can you remove
forehead wrinkles with injections
of botulinum toxin ?

An injection of botulinum toxin works by blocking frontalis muscle activity. This muscle extends from the base of the skull to the brow arches, but when treating forehead wrinkles, only its anterior portion — between the hairline and the eyebrows — is targeted.
The precision of the procedure and the doctor's experience are crucial to achieving a natural, harmonious result. The number of injection points, the dose injected at each point and their exact location make all the difference. The aim is to avoid a frozen forehead and any risk of eyebrow drooping, preserving a lively expression and opening up the eye area. Of course, if the patient wishes, more complete muscle blocking can be performed.

Treatment procedure

The injection is quick, taking about one minute, and causes only a slight tingling or warm sensation. To optimise the result and achieve a harmonious opening of the eye area, it is advisable to combine forehead wrinkle treatment with treatment for frown lines and crow's feet — a comprehensive approach that produces a more balanced result.
The effect appears gradually : the first improvements are noticeable from the second day, and the final result is achieved after one week. A follow-up consultation is scheduled between one and three weeks after the injection, allowing a free touch-up if needed. The effects last an average of five to six months.

Forehead wrinkle treatment should always be accompanied by treatment of the frown line and crow's feet.
There is a balance of muscle forces around the eyebrow :

  • Two muscles pull the eyebrow downwards : the corrugator muscle, responsible for frown lines, and the orbicularis oculi muscle, responsible for crow's feet.
  • Only one muscle raises the eyebrow : the frontalis muscle, responsible for forehead wrinkles.

Botulinum toxin works by reducing or blocking muscle activity. On the forehead, the frontalis muscle is the only muscle that raises the eyebrow. If only this muscle is treated without neutralising the two depressor muscles, the effect becomes unbalanced : the eyebrow inevitably droops.

Why have forehead wrinkle injections performed by an experienced doctor ?

It is crucial to consult an experienced doctor, as this ensures safe, natural and lasting results.

  • Expertise and technical skill

An experienced doctor has a thorough understanding of facial anatomy and has mastered injection techniques. This ensures injections are performed precisely in the correct muscles, maximising treatment effectiveness and minimising the risk of complications.

  • Personalised treatment

Every face is unique, and an experienced doctor knows how to adapt the dose and technique to each patient's specific needs. This personalised approach achieves natural, harmonious results, avoiding frozen or artificial expressions.

  • Understanding contraindications

An experienced doctor identifies contraindications and decides whether a patient is a suitable candidate for injections.

  • Safety and risk reduction

Although botulinum toxin injections are generally safe, they carry risks, as does any medical procedure. An experienced doctor is trained to minimise these risks and manage potential complications, such as bruising or asymmetry.

  • Harmonious appearance

Experience enables the doctor to perform injections that preserve and enhance the face's natural appearance. An experienced doctor knows how to improve proportions and achieve results that are subtle yet visible.

  • Lasting results

With a well-mastered injection technique and an excellent understanding of the products, an experienced doctor can achieve longer-lasting results. The patient therefore benefits from longer intervals between sessions and greater satisfaction.

Results before / after injections of
botulinum toxin into forehead wrinkles

The results of botulinum toxin injections appear gradually : they become noticeable from the second day and fully stabilise around the seventh day. The forehead then becomes visibly smoother.
A follow-up appointment is routinely scheduled between seven and ten days after the session to provide a free touch-up if necessary. The intended result should remain natural, unless the patient wishes otherwise ; forehead movement must be preserved to allow the eyebrows to rise and avoid any frozen expression. It is essential to avoid eyebrow drooping and instead encourage an opening of the eye area, bringing radiance and freshness to the face. Sometimes the outer part of the eyebrow rises more prominently, creating a triangular shape known as the « Mephisto » effect. This phenomenon is linked to individual overactivity of the lateral frontalis muscle ; it cannot always be anticipated at the first injection, but is easily corrected during the touch-up. The treatment generally lasts between four and six months.

Side effects and aftercare

The injected area may look red and swollen for around twenty minutes. Headaches are a common side effect and last no more than two days.
Touching the treated area on the same day is not recommended. Sport and intense heat should be avoided for two days. Hair washing and eyebrow care are permitted from the following day.

How can wrinkles on the
forehead be filled ? Hyaluronic
acid

For certain indications, hyaluronic acid injections can improve the appearance of forehead wrinkles. Two techniques can address this aesthetic concern :

  • Injection directly into the wrinkle : a hyaluronic acid with very fine particles, often a Skinbooster, is injected with a cannula in very small quantities, superficially along the wrinkle. The aim is not to eliminate the wrinkle completely, as excess product could create small irregularities visible beneath the skin. This treatment provides a temporary result, generally lasting a few months, as continued contraction of the frontalis muscle accelerates product resorption. To prolong the effect, combining this treatment with botulinum toxin injections is recommended.
  • Injection to restore the forehead's convex contour or correct a hollow : a firmer, volumising hyaluronic acid is injected deeply with a cannula, between the muscle and bone. The aim is to restore volume, stretching the skin and reducing wrinkles. Results last an average of two years. Here again, combining treatment with botulinum toxin is recommended, as the frontalis muscle continues to contract and could worsen wrinkles over time.

The results of hyaluronic acid injections are visible immediately. Slight temporary swelling may occur. For filling hollows or restoring forehead convexity, the effect lasts around two years, whereas direct treatment of wrinkles provides a shorter-lasting result, of a few months.

Prices for botulinum toxin injections for forehead wrinkles in Geneva

In Geneva, the price of forehead wrinkle treatment with botulinum toxin injections is 300 CHF for one area in women and 350 CHF in men. It is 450 CHF for two areas in women and 500 CHF in men, then 600 CHF for three areas in women and 650 CHF in men. When additional correction is indicated, a hyaluronic acid injection can be performed at a price of 600 CHF per syringe.

A personalised treatment plan is established during the first consultation to adapt the quantities injected to the patient's anatomy, age, facial movement and aesthetic expectations.
The aim is to achieve a relaxed, rested forehead that is never frozen, with natural, harmonious results.
All injected products are certified and comply with Swiss standards.
The treatment cost depends on the number of areas treated.
Three injection areas are generally distinguished in the upper face : the frown line (between the eyebrows), forehead wrinkles (horizontal) and crow's feet (at the corners of the eyes). Prices are also adjusted according to sex, as men have stronger muscles requiring a higher dose than women.

For women

  • 1 area (e.g. : forehead alone or frown line) : 300 CHF
  • 2 areas : 450 CHF
  • 3 areas : 600 CHF


For men

  • 1 area : 350 CHF
  • 2 areas : 500 CHF
  • 3 areas : 650 CHF

In some situations, when wrinkles are too deep to disappear with botulinum toxin alone, an additional hyaluronic acid injection may be offered to refine the result. The price of this procedure is 600 CHF per syringe.

Frequently asked questions about forehead wrinkles

At what age do forehead wrinkles start to appear ?

Forehead wrinkles can start to appear as early as the late twenties, but generally become more visible from the thirties onwards. Genetic factors, lifestyle habits and skincare play an important role in the age of onset.

Which cream should be used for forehead wrinkles ?

Applying creams does not replace injections and offers little benefit. Using creams containing effective active ingredients is recommended. 

Retinol : retinol stimulates collagen production and accelerates cell renewal.

Hyaluronic acid : creams containing hyaluronic acid intensely hydrate the skin.

Vitamin C : vitamin C is a powerful antioxidant that brightens the skin and stimulates collagen production.

Peptides : peptides help strengthen the skin's structure and improve its elasticity.

Applying sunscreen is important to protect the skin from UV damage and prevent wrinkles.

Forehead wrinkles in men

Forehead wrinkles are as common in men as in women and can be treated in the same way.
Men can benefit from the same treatments as women : botulinum toxin, hyaluronic acid and chemical peels.

How can forehead wrinkles be prevented ? How can forehead wrinkle formation be prevented?

To prevent forehead wrinkles, it is essential to protect the skin from the sun with sunscreen, moisturise regularly, eat a healthy diet rich in antioxidants, avoid smoking and manage stress. Facial exercises may also help strengthen facial muscles.

How long do the results of forehead wrinkle treatments last ?

The duration of results depends on the treatment performed. Botulinum toxin injections generally last six months. Laser treatments and chemical peels can have lasting effects, but maintenance sessions are needed to preserve the results.

Can facial exercises really reduce forehead wrinkles ?

Although results vary from person to person, facial exercises are a natural method that complements medical treatments.
These exercises involve specific movements that tone muscles and stimulate collagen production.

How can forehead wrinkles be removed without botulinum toxin ?

Some patients prefer to avoid botulinum toxin injections. Although alternatives exist, botulinum toxin remains the standard treatment.  

  • Hyaluronic acid.
  • Chemical peels.
  • Microdermabrasion.
  • Laser.

At what age should forehead wrinkle treatment begin ?

The age at which treatment starts depends on several individual factors. Starting preventative treatments as soon as the first static wrinkles appear is recommended.

Forehead wrinkles : botulinum toxin or hyaluronic acid ?

The choice between botulinum toxin and hyaluronic acid depends on the severity stage and the patient's wishes. 

Botulinum toxin : botulinum toxin injections are the standard treatment. The result lasts around six months.

Hyaluronic acid : hyaluronic acid cannot be used to fill forehead wrinkles. The only indication is a hollow in the forehead. Injecting it stretches the wrinkles.

Combining both : in some patients, combining botulinum toxin and hyaluronic acid provides the best results, treating both dynamic and static wrinkles.

How should you choose the right doctor to treat forehead wrinkles ?

To choose the right doctor, it is important to look for a qualified, experienced professional who specialises in aesthetic treatments. An initial consultation allows you to discuss your expectations and ask any questions before starting treatment.

Are botulinum toxin injections safe for treating forehead wrinkles ?

Yes, botulinum toxin injections are safe when performed by an experienced doctor. This is a non-invasive procedure that temporarily relaxes the muscles responsible for wrinkles, producing natural results. Side effects are generally mild and temporary : bruising or slight tenderness at the injection site.

Are forehead wrinkle treatments painful ?

Treatments cause little pain. Applying an anaesthetic cream before injections is not really necessary.

What skincare is recommended to prevent forehead wrinkles ?

To prevent forehead wrinkles, using products containing moisturising ingredients, antioxidants and retinol is recommended. Daily application of a broad-spectrum sunscreen is essential to protect the skin from UV rays. 

Forehead wrinkles : what can be done ?

Forehead wrinkles are a sign of skin ageing. Several methods can treat and prevent them.

  • Sun protection.
