What is hyaluronic acid?

Naturally present in our skin tissues, the presence of hyaluronic acid diminishes over time. Today, many food supplements contain it, and it can also be found in certain anti-aging creams. Here's everything you need to know about hyaluronic acid.

What exactly is hyaluronic acid?

Discovered in 1934, hyaluronic acid is a molecule derived from the carbohydrate family. Naturally present in skin tissues, it was initially extracted from rooster combs, but this process has now been replaced by biotechnological synthesis, a safer, less expensive, and higher-yielding method.

Hyaluronic acid preserves the tone and elasticity of your skin and helps combat external aggressions that accelerate the premature aging of our cells. The presence of hyaluronic acid in our body decreases with age and in the face of external aggressions (UV, environmental pollution, etc.). It is estimated that a child has twice as much as an adult of 50 years old.

Today, hyaluronic acid is used in cosmetics for its moisturizing and plumping properties. This humectant is capable of attracting and retaining a large amount of water within the skin. Moreover, depending on its molecular weight, hyaluronic acid penetrates the skin to varying depths, and its benefits differ.

What are the benefits of hyaluronic acid for your skin?

Hyaluronic acid is now widely favored in the formulation of anti-aging cosmetic products. Nevertheless, it would be a shame to consider this active ingredient only for its plumping action, as its scope of action is much broader. Indeed, you can use hyaluronic acid for:

• Repairing and strengthening the skin barrier: If your epidermis is damaged, bacteria and chemicals penetrate and can easily damage the deep layers of your skin. The first signs of this problem are skin that feels tight, itchy, peels, or becomes dull. By adding hyaluronic acid to your routine, you will restore the hydration of your epidermis while strengthening your skin's hydrolipidic film;
• Keeping skin plump: An anti-aging plumping serum formulated with hyaluronic acid helps retain water in the dermis, thus giving the face a bouncy appearance;
• Filling in wrinkles and fine lines: An anti-aging serum formulated with hyaluronic acid is an effective barrier against tissue dehydration. Acting on the skin's surface, it mixes with water to fill intercellular spaces and skin breaks, which are responsible for wrinkles and fine lines;
• Promoting healing: Applying hyaluronic acid to wounds or injured tissues accelerates skin healing;
• Calming and soothing inflammation, superficial burns, and irritations of delicate skin;
• Restoring elastic and supple skin: Like collagen, hyaluronic acid is the ideal ally to reactivate skin elasticity and tone.

Its dangers

Hyaluronic acid is generally safe, as our body naturally contains it.
Only hyaluronic acid injections sometimes pose a problem, but they do not harm your health. Simply, some people may develop allergies after a hyaluronic acid injection.

In this case, itching may develop, and the skin becomes sensitive, sometimes leading to small bruises and redness. Fortunately, the problem resolves naturally after only a few days.

How is hyaluronic acid used?

In cosmetic medicine?

With its reputation for anti-aging action, the use of hyaluronic acid is now widespread, and it can be found in our daily cosmetic products, from day creams to serums and eye contour treatments.

There are two types of hyaluronic acid that do not penetrate the skin in the same way and have different effects:

• High molecular weight hyaluronic acid. Too thick to penetrate deep into the skin, it simply retains water on its surface for a nourishing and softening effect. This type of acid is ideal for blurring fine lines and improving the hydration of still young skin;
• Low molecular weight hyaluronic acid. This second type of active ingredient has the ability to penetrate deeply into the layers of the epidermis. Its plumping action effectively combats skin aging.

In food?

Hyaluronic acid-based food supplements can be taken in addition to cosmetic treatments to enhance their action and redensify the dermis in depth.

When ingested orally, hyaluronic acid helps compensate for the loss of production by the body and helps limit the signs of skin aging.

In aesthetic medicine?

In aesthetic medicine, hyaluronic acid is mainly used in the form of injections to fill skin volume loss or to deeply rehydrate the skin.

There are two types of injection:

• Cross-linked hyaluronic acid is particularly popular for: nasolabial folds, which run from the sides of the nose to the corners of the mouth, and marionette lines, located on each side of the mouth;
• Skin boosters, which deeply hydrate the skin and give it a smoother, firmer appearance.

Is hyaluronic acid suitable for all skin types?

Hyaluronic acid is one of the best-tolerated active ingredients, regardless of your skin type. Here are its benefits, depending on your skin concerns.

For skin prone to aging

Hyaluronic acid is an exceptional ally for delaying skin aging and minimizing the signs of aging. It notably stimulates collagen, which helps firm your skin. In addition, hyaluronic acid smoothes wrinkles and fine lines while strengthening the skin and protecting it from the external environment.

For oily, blemish-prone, or combination skin

Subject to UV rays, pollution, and particles, young skin can become dry. Therefore, it needs hydration to prevent excess sebum. Thanks to hyaluronic acid, sebum production is regulated, and shine is thus reduced.

For dry skin

Hyaluronic acid deeply hydrates your skin and, most importantly, improves its texture. It also strengthens your skin barrier. In this way, the skin is better able to retain water, which prevents dehydration.

For dull skin

When the skin lacks water, it is unable to effectively fight against oxidative stress which dulls the complexion. With hyaluronic acid, the skin barrier is strengthened, and the skin is able to defend itself against external aggressions that alter its radiance.
