Hyaluronic Acid

Acide Hyaluronique

ONE OF THE MOST BENEFICIAL INGREDIENTS FOR THE SKIN


Like collagen, whose production inevitably declines with age (starting at 25), hyaluronic acid, which is naturally produced by the body, also sees its production decrease by 6% every 10 years. This leads to the formation of fine lines and skin laxity — the face loses its fullness. Yet hyaluronic acid and collagen are essential for maintaining skin elasticity and youthfulness. Collagen provides firmness and hyaluronic acid nourishes and hydrates collagen.

More precisely, hyaluronic acid is a carbohydrate, a form of viscous sugar found mostly in the skin and responsible for retaining water in tissues. Its main strength: it can hold up to 1000 times its weight in water. It acts like a real sponge that attracts and retains water to provide instant hydration, smooth wrinkles and fine lines, plump the skin and boost radiance. It also has antioxidant and healing properties...

BENEFICIAL IN EVERY ROUTINE


It is particularly recommended for dehydrated skin due to its powerful hydrating properties, but the truth is that almost all of us lack hydration — even the oiliest skin types. It is important not to confuse dry skin with dehydrated skin.

It is also perfectly suited for sensitive skin that needs soothing.

In short, it is suitable for all skin types! It does not clog pores and does not cause irritation. There is no risk in including it in your routine. Everyone can benefit from its properties regardless of age. It is very easy to use as it can be applied morning and evening, in every season. It is a lifesaving active ingredient after a long-haul flight, a day exposed to air conditioning or heating, or before an important evening.

THE DIFFERENT MOLECULAR WEIGHTS OF HYALURONIC ACID


LOW MOLECULAR WEIGHT HYALURONIC ACIDS

They contain smaller particles that penetrate deeper into the skin. They boost collagen production and improve firmness. This molecular weight is commonly found in formulations known to plump the skin, fill wrinkles and improve skin tone.

HIGH MOLECULAR WEIGHT HYALURONIC ACIDS

Larger in size, they retain water on the surface of the skin, maintain hydration and protect the skin against external aggressors. They also enhance the skin’s radiance.

Hyaluronic acid can appear under different names in cosmetic formulas: sodium hyaluronate, glycoaminoglycan, hyaluronan, Hydrolyzed Sodium Hyaluronate and sodium PCA.

The effects of hyaluronic acid are temporary, so it must be continuously replenished in the skin.

We have a preference for essences and lightweight serums that absorb quickly and deeply without leaving any greasy residue.
