MCC is naturally rich in hyaluronic acid, GlcNAc (ß1>4)GlcA(ß1>3), biochemically referred to as glycosaminoglycan (GAG), which is the skin's agent for hydration and support for tone and elasticity. Fifty year olds are estimated to have less than half the hyaluronic acid that was present in their youth, making replenishment of this substance critical for continued healthy skin.

Hyaluronic acid's unique and scarce glycosaminoglycan nature and 1 million daltons of molecular weight give it “molecular sponge” properties as it moisturizes (by forming a film on the skin enabling it to hold water), protects, lubricates, prevents moisture-loss from the skin and maintains the structural integrity of the tissues. The viscoelastic properties of its films on the skin resemble its functions in the intercellular matrix inside the skin. In addition to its superior moisturizing properties, it improves the texture of the skin by rendering it “naturally” silky and yet allowing the skin to maintain its breathability.

In topical applications, hyaluronic acid preserves the hydrophilic barrier of the skin. It is a film-former which improves the skin's texture and accelerates wound healing as it favors cell proliferation and facilitates cell migration. Because of its protective properties, hyaluronic acid provides desquamation of the stratum corneum, hence restoring the smoothness and elasticity of tissues overexposed to the sun. MCC absorbs UV light in the middle wavelengths and, therefore, also has a mild sunscreen component.

Clinical studies completed in 1996 by Eric Dupont, PhD Clinical Investigator at Aeterna Laboratories in Quebec, Canada, provided substantial evidence that MCC can help reduce the signs of skin aging, specifically sagging, dehydration, fine lines and wrinkles. According to the findings, MCC appears to accomplish age retardation by aiding dermal fibroblast cells to prevent the destruction of collagen by inhibiting the production of the destructive enzymes, collagenases.
