Hyaluronic Acid (commonly referred to as HA) is the skin’s key ingredient to retain water. It is what gives our skins the gorgeous volume and elasticity! A slower rate of skin cell renewal with ageing results in decreased HA, collagen, and elastin production which ultimately thins the skin. The skin which lost volume will show classic sign of ageing, such as drooping, wrinkles, and fine lines. External factors like sun exposure, gravity, repetitive motion, diet, cigarette smoking, disturbed night sleeps, and stress contribute to the process too.
