Hyaluronic Acid

Acide Hyaluronique

Hyaluronic acid moisturizes, softens and firms your skin thanks to its viscoelastic properties. Naturally present in our body, in particular our eyes, it constantly lubricates the cornea and plays an important role in hydrating tissues and cells.

This ingredient is known to be non-allergenic, non-toxic and there is no risk of over-dosage.

Used as a moisturizing agent, it softens the skin and visibly reduces fine wrinkles. This ingredient is commonly used after a dermatological peeling in order to hydrate new cells. It provides them with an excellent environment and favors their growth.

Finally, hyaluronic acid is used in cosmetics in particular due to its contribution to the maintenance of the skin’s cohesion and structure: 1 g of hyaluronic acid can absorb up to 1 L of water.


Collagen

Collagène

Collagen is located in the center of the dermis. It is a protein in the form of fiber produced by fibroblasts. This protein allows the skin to be both firm and elastic and is part of the structure of the skin. The elastin fibers also play an important role by contracting and thereby ensuring a certain degree of elasticity. Collagen is also a hydrating agent able to absorb 30 times its weight in water and it is able to infiltrate into the skin.

Synthetic collagen is a large molecule that has greater difficulty in penetrating the skin. If it is applied in a thin layer on the skin, it prevents the water inside from evaporating and also allows other active ingredients to be more effective. The cells are rehydrated and the skin becomes firmer and more radiant.


Hexapeptides/Pentapeptides

Hexapeptides/Pentapeptides

Botulinum toxin revolutionized cosmetics due to its remarkable anti-wrinkle properties. Because it is highly toxic, its use is strictly controlled and can only be prescribed by a physician.

Today, molecules exist that are not toxic and act on the muscle contractions that create facial wrinkles. A topographical analysis of the skin has demonstrated that the regular use of this molecule significantly reduces the depth of wrinkles. These studies were conducted in vitro, as well as on female volunteers. (Excerpt from the International Journal of Cosmetic Science)
