6 misconceptions about hyaluronic acid.

True. Hyaluronic acid is a compound naturally produced by the body. It is notably present in connective tissue, eyes, and skin. Almost 50% of its total amount is located in the dermis, the deep layer of the skin. It forms the extracellular matrix and serves as a support for collagen and elastin fibers. It also ensures skin hydration as it acts like a molecular sponge: it captures water molecules and retains them.

However, over the years, the body's production of hyaluronic acid tends to decrease (a drop of about 6% per decade), which leads to skin sagging, the appearance of initial wrinkles, and a decrease in cellular activity...From the age of 50, it is thus proven that the stock of hyaluronic acid is halved !

False. Hyaluronic acid is a molecule that is generally well tolerated by all skin types and does not appear to have a sensitizing potential. It does not present any undesirable side effects when applied externally. This excellent tolerance comes from the fact that this molecule is already present in the skin and is not foreign to the body, which tolerates and absorbs it all the better.

True. As previously seen, the stock of hyaluronic acid is halved after 50 years, which results in deepening wrinkles and increasingly visible skin sagging. Given this observation, it is particularly interesting toprovide the skin with hyaluronic acid through dermocosmetic care. Indeed, this remains less invasive therefore significantly less risky than injections...

Nevertheless, it is clear that for a more pronounced effect on wrinkle reduction, injections are more effective! As the syringe penetrates deeply, the active ingredient can fill in wrinkles, particularly frown lines, nasolabial folds, or forehead wrinkles. However, these injections can be accompanied by side effects, the least severe being edema, skin redness, itching, erythema, and slight bruising.

False. Hyaluronic acid treatments can be used as early as your twenties.

Indeed, in addition to combating skin aging, hyaluronic acid is essential for thehydration of the skin. Capable of capturing and retaining up to 1,000 times its own weight in water, this active ingredient presents itself as the solution for delivering a shot of hydration to dry and dull skin or those that struggle with the harshness of winter, starting as early as 20 years old.

Between the ages of 30 and 40, a hyaluronic acid treatment is relevant for mitigating the first signs of aging.With its low molecular weight, the molecule penetrates deeply into the epidermis to strengthen and stimulate its own production naturally produced by the human body. Thus, the appearance of wrinkles is delayed and the small signs of age already present are smoothed out.

False. Contrary to popular belief, hyaluronic acid injections are different from Botox injections. Indeed, they only affect the dermis and not the muscle. These formulas restore volume and hydrate the skin, while Botox relaxes the muscle. The effect of hyaluronic acid on the skin is not permanent. It fades after 6 to 20 months, which requires renewal.

False. In hair care, hyaluronic acid can fulfill several functions to enhance the hair on a daily basis.

• Preventing split ends: A treatment with hyaluronic acid applied to the lengths of the hair can preventhair breakage and limit split ends, making your hair softer and stronger.

• Taming Unruly Hair: Rebellious hair tends to puff up and frizz. A treatment rich in hyaluronic acid applied to the lengths of the hair can smooth out frizz and make styling easier.

• Restoring Radiance: Several factors such as pollution, stress, smoking, or even hair coloring can make hair dry and dull. A treatment with hyaluronic acid deeply hydrates the hair fiber and repairs damaged hair. Once hydrated and repaired, your hair regains its shine.

• Caring for your curls: A treatment rich in hyaluronic acid reshapes and restructures your curls. It also adds volume to your hair. If your hair is naturally curly, this active ingredient helps to keep it shiny, flexible, and elastic. Finally, on kinky hair, the use of this active ingredient gives character to the hair and keeps it hydrated.
