Hyaluronic acid (HA) is a sugar found naturally in our skin that holds water and helps keep it hydrated and plump. Basically, hyaluronic acid increases hydration in the skin, which can keep your skin looking fresh, full, and bouncy. The collagen in our dermis forms the structure of the skin, Natural hyaluronic acid is bound to collagen on one side and links to water molecules on the other, giving skin its plumpness. The HA within our bodies holds a thousand times its weight in water to not only retain all that moisture in our skin and joints, but also prevent all that moisture from evaporating into the air. It will make the skin appear more dewy and younger because it improves skin elasticity.
Apply hyaluronic acid as a serum in the mornings and evenings after cleansing and before applying moisturizer and sunscreen. I think the best hyaluronic acid in skin care products are serums because they are more effective at penetrating the skin barrier than, say, a cream or toner.
Always remember to perform an allergy test before applying. Simply apply a drop or two to the back of the hand and wait several hours (not all reactions occur immediately) to check for any adverse effects.This statement has not been evaluated by the Food and Drug Administration.
