Hyaluronic acid (HA) is a molecule that our bodies naturally produce and can be found in our joints, connective tissue and eyes. About 50 percent of the hyaluronic acid in our bodies lives in our skin.
Hyaluronic acid (HA) is the key molecule involved in skin moisture that has unique capacity in retaining water –up to 6000 times the weight of the molecule itself.
Most of the hyaluronic acid dwells in the extracellular matrix, the scaffold which holds up the cells of our skin. It is found in both the epidermis and the deeper dermis, where it is vital forskin hydration, metabolic processes, skin repair, and protection against free radical and UV damage.
Due to aging process and environmental factors, the production of hyaluronic acid in our skin reduces and this leads to appearance of dryness, fine lines and wrinkles.
