Hyaluronic acid: boosts the skin’s moisture level.  This naturally occurring acid may contain 1000 times its own weight in water, and this is the reason why it is ideal for adding moisture to the skin. Hyaluronic acid is a natural polysaccharide (large sugar molecule) that occurs in various tissues (skin, synovial fluids of joints, connective tissues). It is a powerful humectants who is responsible for tissue hydration, lubrication, & tissue stability, This natural carbohydrate from the group of mucopolysaccharides is an integral part of the dermis, but with age, its concentration in the tissue decreases significantly. It acts as a molecular sponge, binding protein and water (2% hyaluronic acid binds 98% water, builds a gel-like solution). Applied to the skin, it makes an elastic, transparent film, which stimulates the natural protective mechanisms. In the deeper layers, it binds to collagen and elastin, which restores the volume of the skin. It binds a large amount of water, so the skin becomes tighter, moisturized, looks younger, more beautiful and supple. It is biocompatible, safe and well tolerated.
