50% of the human body’s hyaluronic acid is present in the layers of skin. It proves its loyalty towards skin by retaining the moisture which makes it look more healthy and radiating. Also known as hyaluronan, its amount constantly decreases with ageing and exposure to UV radiations. Using hyaluronic acid as a supplement speeds up the wound healing process and reduces the appearance of fine lines and wrinkles. It can also treat facial redness and improve the skin elasticity.
