What is hyaluronic acid and how does it work under the skin?

Hyaluronic acid is a molecule naturally present in the human body. It is found in the synovial fluid of joints, in the vitreous humor of the eye, and in the intercellular spaces of our skin.

In the skin, hyaluronic acid plays an essential role in protection and hydration. The function of this molecule is to capture and retain water to fill the space between skin cells, giving our skin its youthful, elastic appearance.

In aesthetic medicine,hyaluronic acid is synthesized and injected into the face for a generally anti-aging effect. It can be used :

• As a filler, for the treatment of wrinkles, fine lines and furrows
• To compensate for age-related volume loss
• To reshape certain areas of the face, such as the nose or chin

What areas of the face are treated with hyaluronic acid injections?

Hyaluronic acid is used for a wide range of indications. The areas most commonly treated with this molecule are :

• Nasolabial folds, extending from the root of the nose to the corners of the lips
• All areas where wrinkles and furrows form (frown lines, bitterness folds, perioral wrinkles), with the exception of dark circles.
• Lips, whether too thin or asymmetrical
• Temples, which tend to hollow with age
• The oval of the face, which slackens over time, leading to the formation of jowls
• The nose, where hyaluronic acid can be used as an alternative to surgical rhinoplasty to correct a number of moderate defects.
• The chin, for non-surgical reshaping.

Hyaluronic acid is often presented as an alternative to cosmetic surgery. It’s a light treatment with the advantage of being rapid and non-invasive, with a simple recovery. Indeed, no social eviction is required after a hyaluronic acid injection, and the patient feels no pain.

Another advantage of this technique is its reversibility, which reassures patients intimidated by the definitive dimension of surgery. In fact, hyaluronic acid is a biodegradable product, naturally resorbed by the body. Depending on the area treated and the precautions taken by the patient, it generally lasts between 12 and 18 months.

How can I optimize the effect of a hyaluronic acid injection on the face?

Hyaluronic acid does not stay in place permanently, but its hold can be extended by taking these few precautions:

• Avoid heat sources during the weeks following the injection (sauna, hammam, aesthetic treatments such as laser).
• Avoid sun exposure for the first few weeks, then protect your skin with a sunblock cream.
• Adopt or maintain a healthy lifestyle, based on a diet free of deficiencies, restorative sleep, and a reduction in tobacco and alcohol consumption.

All these elements help maintain youthful skin and prevent hyaluronic acid degradation.

Finally, for your treatment, it’s important to choose a good practitioner who uses a quality product adapted to your skin and aesthetic goals.
