What is hyaluronic acid?
Hyaluronic acid injection is the ideal technique for filling wrinkles, restoring skin volume and sculpting facial contours.
Hyaluronic acid is a molecule naturally present in the dermis, joints and cartilage. The body produces it naturally to renew skin tissue and moisturize the skin.
The injectable hyaluronic acid used in aesthetic medicine and cosmetic surgery is identical to that produced by the body, and is obtained through biotechnological processes. It is now widely used and recognized for its cutaneous tolerance and natural-looking properties. It is an absorbable product and its injection is different from botulinum toxin injection, but the treatments are complementary. Hyaluronic acid is very often used in combination with botulinum toxin to obtain the best possible results as part of a global approach.

What are the applications of hyaluronic acid?
- Filling wrinkles and volumes
Hollow, static wrinkles (nasolabial folds, bitterness folds, wrinkles around the mouth, etc.) give a sad or tired appearance. Filling these wrinkles with hyaluronic acid can give the face a youthful lift. Hyaluronic acid can also be used to treat sagging skin by filling in volumes. Hyaluronic acid can also be injected into the back of the hands to restore lost volume and reduce the appearance of prominent veins and tendons.
- Plump up lips
Over time, lips naturally tend to lose volume, resulting in a thinner, less defined appearance.
Hyaluronic acid injections can :- Redraw the contour of the mouth
- Redefining the Cupid’s bow
- Increase lip volume for better symmetry
- Moisturize lips
- Medical rhinoplasty
Non-surgical rhinoplasty (sometimes called “medical rhinoplasty” or “liquid rhinoplasty”) is a rapid procedure for patients who do not wish to undergo surgery. It involves the use of a dermal filler such as hyaluronic acid to :- Form a flat nasal bridge
- Straightening a slightly slanted nose
- Reduce the perception of a dorsal hump
- Create better symmetry

Frequently asked questions
How long does the result of a hyaluronic acid injection last and is it immediate?
The duration of results from hyaluronic acid injections varies according to a number of factors, including the area treated, the type of hyaluronic acid used and the quantity injected. In general, results last between 6 and 18 months.
Results of hyaluronic acid injections are generally immediate, although some patients may experience slight swelling or bruising at the injection site, which may take a few days to resolve. Definitive results generally appear within a few days of treatment, once swelling and bruising have disappeared.
Is the result natural?
The result of hyaluronic acid injection will be very natural if it is performed by a qualified physician experienced in aesthetics.. The appearance of wrinkles is reduced and skin hydration is improved, without giving the face a frozen appearance, but rather adding radiance.
What precautions should I take before and after a hyaluronic acid injection?
It’s important to tell your specialist if you’re ill, or if you’re taking any medication. Alcohol consumption before and after injections increases the risk of hematoma.
After the session, you should avoid moving your face for 3 hours and also avoid sauna, violent sports, any aesthetic procedure (peeling, waxing, etc.) on the treated area, as well as any compression of the area (swimming goggles, motorcycle helmet, etc.).
What are the possible complications of hyaluronic acid?
Although hyaluronic acid injections are considered safe, it’s vital to turn to trained doctors who use high-quality hyaluronic acid to limit any possible complications.
- Redness, swelling, bruising or pain at the injection site: these side effects are generally mild and disappear spontaneously in the days following treatment.
- Infections: although rare, infections may occur after an injection.
- Allergic reactions: although very rare, it is possible to develop an allergic reaction to hyaluronic acid.
- Granulomas: lumps or nodules may form under the skin after a hyaluronic acid injection. Although rare, these granulomas may require further treatment.
How much does a hyaluronic acid injection cost?
Depending on the doctor, the consultation fee varies from €50 to €70. Injections start at €350 for 1ml, depending on the area to be treated and the quantity to be injected. These prices are indicative and include VAT. The precise estimate will be drawn up by the doctor during the consultation.

The result
After a hyaluronic acid injection session, you can expect visible results immediately: wrinkles filled in, volumes restored or lips plumped, depending on the area treated. The appearance of your skin will continue to improve in the days that follow, thanks to the moisturizing and volumizing action of hyaluronic acid.
Although slight redness or swelling may appear, this quickly fades, allowing you to resume your activities immediately. Results are natural and long-lasting, yet reversible over time.
