Hyaluronic acid

Hyaluronic acid (HA) is a substance naturally present in our bodies. It is a glycosaminoglycan, a long chain of polysaccharides (sugars) found mainly in the skin, eyes and joints. It plays an essential role in skin hydration and joint lubrication.

One of its main characteristics is its ability to retain water - up to 1000 times its weight! This property makes it a key element in keeping skin hydrated, elastic and firm. As we age, the concentration of hyaluronic acid in our skin decreases, contributing to the formation of wrinkles and loss of facial volume.

The different types of hyaluronic acid

There are several types of hyaluronic acid, distinguished by their molecular weight.

  • High molecular weight hyaluronic acid : it remains on the skin's surface, creating a protective film that helps maintain hydration. This is the type often found in moisturising serums and creams.
  • Low molecular weight hyaluronic acid This type penetrates deeper into the skin and can stimulate collagen production, boosting the skin's elasticity and firmness.
  • Cross-linked hyaluronic acid Hyaluronic acid: used mainly in dermal filler injections, this type of hyaluronic acid is chemically modified to last longer in the tissues.

Each of these types of hyaluronic acid has specific applications depending on the skin's needs and treatment objectives.

How does hyaluronic acid work on wrinkles?

Hyaluronic acid is widely used in anti-ageing treatments for its moisturising and volumising effects. Here's how it works to reduce wrinkles:

  • Hydration and water retention: by attracting and retaining water, hyaluronic acid keeps skin well hydrated, immediately improving its appearance. Well-hydrated skin is smoother and more supple, and fine lines caused by dehydration are reduced.
  • Volume and firmness: hyaluronic acid injections can fill in wrinkles and restore volume lost with age. When hyaluronic acid is injected into the skin, it acts like a 'cushion' to support facial structures and smooth out hollows or wrinkles.
  • Stimulation of collagen synthesis: studies show that hyaluronic acid can also stimulate collagen production. Collagen is an essential protein for skin firmness and elasticity. With age, collagen production declines, but the use of hyaluronic acid can help reverse this process.

The different types of wrinkle treated with hyaluronic acid

Hyaluronic acid is effective against several types of wrinkle.

  • Static wrinkles Wrinkles: caused by the loss of collagen, elastin and hyaluronic acid, these wrinkles are visible even when the face is at rest. Hyaluronic acid injections fill these wrinkles. Examples include nasolabial foldand folds of bitternessand lip wrinkles.
  • Dynamic wrinkles These wrinkles appear with repetitive movements of the facial muscles, such as smiling or frowning. Although Botox is often used for these types of wrinkles, hyaluronic acid can also be used as a complement in certain indications. These include forehead wrinklesand crow's feet wrinkles and lion wrinkle.
  • Dehydration wrinkles These small, superficial lines appear when the skin lacks moisture. The injection of a specific hyaluronic acid, the Skinbooster It reduces them by improving the skin's moisture content.

All the benefits of hyaluronic acid

As well as its effect on wrinkles, hyaluronic acid has a number of other benefits for the skin.

  • Improved elasticity of the skin : By stimulating the production of collagen and elastin, hyaluronic acid improves the skin's elasticity, making it firmer and more resistant to external aggression.
  • Faster healing: hyaluronic acid promotes the healing of wounds and skin inflammation by regulating inflammation and speeding up tissue repair.
  • Protection against free radicals: hyaluronic acid also has antioxidant properties, which help protect the skin against damage caused by free radicals, such as those caused by exposure to UV rays and pollution.

Applications of hyaluronic acid

There are several ways of using hyaluronic acid to treat wrinkles.

  • Filler injections: this is the most commonly used method for treating deep wrinkles and restoring facial volume. Hyaluronic acid injections are carried out by a doctor, who chooses the type of product and technique to suit the patient's needs.
  • Serums and creams: topical products containing hyaluronic acid are ideal for hydrating the skin's surface. They can be used in addition to injections.
  • Masks and patches: these products contain high concentrations of hyaluronic acid and are used for intense and immediate surface moisturisation.

Who is hyaluronic acid intended for?

Hyaluronic acid is suitable for almost all skin types, and is particularly suited to people who want to combat the signs of ageing, such as wrinkles, loss of firmness and lack of hydration. It is also suitable for those looking for a natural, non-invasive solution to improve the appearance of their skin.

However, it is essential to consult a qualified doctor before considering hyaluronic acid injections. He or she will be able to assess the patient's specific needs and recommend the most appropriate treatment.

Results and maintenance of hyaluronic acid treatments

The results of hyaluronic acid injections are visible immediately after treatment and are optimal three weeks later. The duration of the effects depends on a number of factors, such as the type of product used, the area treated and the patient's metabolism.

In general, the effects can last between 6 and 18 months. Regular maintenance sessions are recommended to maintain results.

Why choose hyaluronic acid?

In conclusion, hyaluronic acid is an effective and safe option for treating wrinkles and restoring the skin's youthful appearance. Its ability to hydrate, fill and stimulate collagen production makes it an essential ally in the fight against skin ageing. Whether through injections, serums or topical treatments, hyaluronic acid meets the specific needs of each patient.

For those considering injections, it is essential to consult an experienced doctor for personalised advice and the best possible results.
