Facial rejuvenation

Aesthetic medicine

Injections of Botox or hyaluronic acid, or the insertion of tensor threads, can give you a “youthful glow” with one undeniable advantage: they are light procedures, carried out in the doctor’s office, and you can resume your activities the same day.

They can also complement surgery when an operation is preferable to achieve true rejuvenation.

Unlike a non-surgical practitioner, who can only perform aesthetic medical procedures, a surgeon can determine what is best suited to your particular needs: light procedures where the result will be harmonious, or surgery such as blepharoplasty, a facelift or lipofilling when aesthetic medicine has reached its limits.

Make an appointment with your aesthetic doctor in Paris for an initial consultation.

The different treatment areas in aesthetic medicine

– Docteur Bernard Hayot

What is aesthetic medicine?

The term aesthetic medicine covers a whole range of medical procedures aimed at improving a person’s physical appearance. These techniques are non-surgical and can be used to treat a wide range of imperfections, such as wrinkles, cellulite or pigmentation spots.

What are the indications for aesthetic medicine?

The indications for aesthetic medicine are wide-ranging. The techniques in use today can treat many imperfections, most of them age-related:
  • Fine lines and wrinkles
  • Sagging skin on the face and body
  • Stretch marks
  • Pigmentation spots (brown spots, lentigines)
  • Scars
  • Body and facial hair removal (long-lasting hair removal)

When should you turn to aesthetic medicine?

Aesthetic medicine is for men and women of all ages who wish to improve their appearance without surgery. Anti-ageing treatments can be started quite early, as the first signs of skin ageing appear from the age of 30. Compared with cosmetic surgery, aesthetic medicine has the advantage of being non-invasive and often reversible. It is a good compromise for patients who are reluctant to take the plunge into surgery, and it can also be used to complement it.

What do I need to know before undergoing aesthetic medical procedures?

Aesthetic medical procedures are valued for their safety. All the technologies used are approved by the health authorities, and only doctors specifically trained in these techniques are authorised to use them. Before any procedure, Dr Hayot reviews the indication, the contraindications, the expected course, the alternatives and the follow-up, so that the plan remains medically coherent for the eye area.

Hyaluronic acid
Hyaluronic acid is a molecule naturally present in our skin, where it ensures hydration, elasticity and tone. It has a volumising effect that compensates for the loss of relief associated with ageing. By re-establishing a harmonious contour, it smooths the wrinkles and folds caused by fat loss and restores fullness to the face. Hyaluronic acid is also very well tolerated and is naturally resorbed by the body. Dr Hayot uses several types of hyaluronic acid, each suited to the area treated: temples, cheekbones, mouth, contour of the mouth, nasolabial fold and so on.
Botox
Botox injections help reduce expression lines and movement wrinkles: crow’s feet and forehead wrinkles, but also wrinkles of the chin and neck. To avoid paralysing the forehead and producing the frozen look seen in many Botox patients, Dr Hayot uses a particular technique known as micro-Botox or derma-Botox. He injects into the superficial layers of the skin of the forehead without touching the muscle: the product acts only on the superficial muscle fibres, and the result is far more natural. At rest, the wrinkles are invisible, but when the face is animated the forehead remains mobile and the expression is preserved.
Belkyra Kybella
This product effectively treats a double chin. Belkyra contains a bile acid naturally present in the body, which destroys fat cells and causes a slight retraction of the skin through the resulting inflammatory reaction. It is an alternative to liposuction, but the injection is performed in the doctor’s office and requires no anaesthesia. The result is permanent.
Tensor threads
Tensor threads are an effective way of countering ageing skin on the face and neck. Through a dual mechanical and biological action, the threads visibly tighten the skin in the treated area and are naturally broken down by the body after 18 months. This is a light technique, generally reserved for patients aged 30 to 45 with moderate skin slackening.
Ulthera
The Ulthera treatment, or Ultherapy, is an advanced technology that uses ultrasound to stimulate collagen production in the dermis. The result is firmer, more elastic skin on the face, neck and décolletage.
Laser treatment
The FRAXEL fractional laser, the latest generation of rejuvenation laser, improves the quality of the skin and, through its tightening effect, smooths wrinkles and the crumpled appearance of the lower eyelid. It stimulates the fibroblasts that produce collagen and elastin, both of which decline with age. Its advantage is very light after-effects, with no social downtime. Several sessions, spaced a few weeks apart, are needed to obtain a convincing result.

Introduction

Injections of Botox or hyaluronic acid, or the insertion of tensor threads, can give you a "youthful glow" with one undeniable advantage: they are light procedures, carried out in the doctor's office, and you can resume your activities the same day.

They can also complement surgery when an operation is preferable to achieve true rejuvenation.

Unlike a non-surgical practitioner, who can only perform aesthetic medical procedures, a surgeon can determine what is best suited to your particular needs: light procedures where the result will be harmonious, or surgery such as blepharoplasty, a facelift or lipofilling when aesthetic medicine has reached its limits.

Aesthetic medicine treatments
There are many aesthetic medical treatments to combat tired, sad and severe eyes. Using your own fat is the ideal way to rejuvenate your face and restore lost volume. Hyaluronic acid helps fill in volume: dark circles, cheekbones, facial contours, etc. Botox is a product regularly proposed to correct expression lines. Belkyra is an aesthetic medicine treatment for reducing a double chin. This technique involves placing biodegradable threads under the skin to tighten the skin by boosting collagen production. Ultherapy uses the benefits of ultrasound to firm skin tissue by stimulating the production of collagen and elastin. The heat released by the laser's light beam has a stimulating effect on fibroblasts and skin rejuvenation.
The different treatment areas in aesthetic medicine

"If you had a magic wand, what would you change?"

A face ages, loses substance and loses volume over the years. As the skin slackens and the muscles contract, wrinkles appear across the face and neck.

The majority of wrinkles in the upper third of the face (forehead, frown lines, crow's feet) are reduced thanks to the neutralizing action of botulinum toxin.

The volumising action of hyaluronic acid can treat other breaks in the skin: nasolabial folds, hollow dark circles, cheekbones, mouth and so on. Injected into the surface of the face, hyaluronic acid also treats a dull, blurred complexion and restores radiance and vitality to the dermis, a treatment known as mesolift.

Treatments

Hyaluronic acid
Ulthera
Tensor threads

Forehead wrinkles are generally caused by overactivity of the forehead muscle, creating unattractive horizontal and vertical marks. But expression lines, even very old and marked ones, are not resistant to botulinum toxin: the treated area becomes smooth and flat again, like a baby's skin.

The challenge for the aesthetic physician is to calm the overactivity of the forehead muscle to erase wrinkles without paralyzing the forehead or freezing the patient's facial expression.

Sometimes, after several years of botulinum toxin treatment in this area, vertical wrinkles known as "sleep wrinkles" may appear. These can be treated with hyaluronic acid injections to fill the skin break.

Treatments

Botox®
Hyaluronic acid

The lion's wrinkle is caused by the action of the very powerful forehead muscles, regularly solicited by frowning. They give a stern, worried look.

In moderate cases, an injection of botulinum toxin is enough to rest the muscle and allow the frown line to disappear completely.

Where the frown line is more pronounced, it is generally preferable to combine Botox with hyaluronic acid. Botulinum toxin injections first soften the expression and relax the glabellar muscles, then hyaluronic acid levels the surface of the wrinkle.

Tensor threads

Hyaluronic acid

Crow's feet wrinkles are caused by the action of the orbicularis muscle, which contracts to form striae at the corner of the eye. When performed subtly, botulinum toxin injections are a highly effective remedy for the treatment of these wrinkles. The aim is not to freeze the smile, and to avoid disharmony with the untreated lower eyelid, which will appear more wrinkled. Moreover, Botox injections in this area can provoke or aggravate an existing malar pocket. So be careful! Properly injected, botulinum toxin calms the muscle to reduce fine lines without altering the patient's facial expression.

Tensor threads Botox® Hyaluronic acid Micro fat injections

Aesthetic medicine can correct certain irregularities in the shape of the nose and avoid the need for surgical rhinoplasty.

Hyaluronic acid injections can be used to rectify the bridge of the nose. They can both mask unsightly bumps and subtly fill hollows to smooth them out.

Filler injections are also an effective solution for rounding or lifting the tip of the nose to make it more attractive.

Medical rhinoplasty can harmonise and correct irregularities of the face over the long term.

Wrinkles on the nose caused by overactivity of the procerus muscle are effectively treated with botulinum toxin injections.

Treatments

Botox®
Hyaluronic acid

Facial sagging due to the loss of fatty volume is one of the first signs of aging. Restoring lost volume by injecting dermal fillers gives an immediate "healthy glow" effect. Volumizing hyaluronic acid is an effective, long-lasting solution (3 years on average). Skilful injections in the cheekbone, temple, cheek and oval of the face can tighten and rejuvenate the face without the need for surgery. Fuller cheekbones give a "baby-face" effect and generally improve the appearance of the nasolabial fold, often secondary to a melting cheekbone.
Treatments
Hyaluronic acid Micro fat injections The furrow deepens and worsens over the years as a result of facial expressions, laughter and smiles, and ends up remaining even when the face is at rest. When the nasolabial fold is only slightly marked, an injection of hyaluronic acid is all that's needed to satisfactorily remove the wrinkle. On the other hand, when the furrow is very deep, it will first be necessary to restore the lost malar volume by raising the cheekbone with hyaluronic acid injections, then, in a second stage, inject the product into the furrow itself. This technique produces a very natural-looking rejuvenation of the face.
Treatments
Botox® Hyaluronic acid The mouth is an important asset in the beauty of the face. That's why the contour of the lips and a good distribution of volumes make for a pretty mouth and harmonize the face. The most common method involves reshaping the mouth by injecting a volumizing product such as hyaluronic acid into the lip to recreate lost volume or restore uneven volume between the two lips. Aesthetic medicine can also restore sagging at the corners of the mouth. Progressive injections aim for a natural result.
Treatments
Hyaluronic acid With age, perioral wrinkles appear around the mouth, giving a "pleated" appearance linked to dehydration and the thinning of the lips. The orbicularis muscle of the lips, which is used regularly, also contributes to the appearance of wrinkles, particularly in smokers ("smoker's wrinkles"). Botulinum toxin injection calms the overactivity of the orbicularis muscle and relaxes the contour of the mouth. Wrinkle by wrinkle, hyaluronic acid injections fill in skin breaks to smooth the contour of the mouth.
Treatments
Botox® Hyaluronic acid Micro fat injections With age, the chin loses volume, resulting in small vertical folds under the mouth that age the facial features. These fine lines that appear on the chin can be treated with botulinum toxin injections, which will make that "crumpled" skin look disappear. When skin laxity is too great, the use of tensor threads can also be an effective solution.
Treatments
Belkyra Tensor threads Ulthera Slackening of the tissues of the oval of the face and the muscles of the neck leads to the appearance of jowls that "break" the natural shape of the face. Hyaluronic acid is a solution for effectively levelling this demarcation and masking jowls naturally. The filler acts as a trompe-l'oeil, postponing the need for a facelift. Tensor threads can also be a highly effective treatment for tightening the oval of the face in the long term. However, if the jowls are very large, only mini-facelift surgery can achieve good results by re-tensioning the muscles and reducing muscle ptosis.
Treatments
Tensor threads Ulthera Horizontal neck wrinkles are creases of movement. With age, the neck becomes increasingly wrinkled and platysmal bands appear. At an early stage, botulinum toxin injections give very good results on platysmal bands. Where the wrinkles are very pronounced, a mini-facelift of the jawline and neck remains the most effective solution.
Treatments
Belkyra Tensor threads Ulthera Hollow dark circles result from the loss of subcutaneous fat. The skin of the lower eyelid is so thin that the bony contours of the eye socket show through it. Hyaluronic acid injections can fill this valley, which runs from the root of the nose to the cheekbone. In the case of coloured, dark or hyperpigmented circles, however, hyaluronic acid injections should be avoided: the thinness of the skin will make the circles look bluish and accentuate the tired appearance of the eyes. Where the circles are excessively hollow, only microlipostructure can durably restore the lost volume.
Treatments
Hyaluronic acid Microlipostructure of hollow dark circles Micro fat injections Treatment of dark and pigmented circles Nano-lipofilling A malar mound is a kind of second dark circle, more or less swollen from one day to the next, which accentuates the tired appearance of the eyes. It is not a pocket of fat but a ptosis of the orbicularis muscle. The solutions for treating malar mounds are hyaluronic acid and cortisone. Early malar mounds are reduced by injecting a very dilute dose of cortisone deep down onto the periosteum, followed by an injection of hyaluronic acid into the hollow of the cheekbone.
Treatments
Hyaluronic acid Laser removal of under-eye bags Blepharoplasty Loss of fat in the tear trough and cheekbone area creates a line between the lower eyelid and the fullness of the cheek. This loss of malar volume also deepens the nasolabial fold, which is no longer supported by the cheekbone. The area is treated by restoring volume with hyaluronic acid. Injected into the tear trough, the product helps rebalance the volumes and remove the hollow line that gives the face a tired appearance.
Treatments
Hyaluronic acid Blepharoplasty Marionette lines are wrinkles that run from the corner of the mouth to the chin. The muscles often involved in laughter and facial mimicry are the main cause of this expression wrinkle, although sagging skin is also responsible. In aesthetic medicine, the bitterness fold is treated with hyaluronic acid injections. However, when skin sagging is too great, a mini facelift is required, or tensor threads may be used.
