Hyaluronic acid is a sugar molecule that occurs naturally in the skin and in all tissues in the body. Because of its unique ability to bind water hyaluronic acid helps to give the skin its shape and volume. As early as the 1930s researchers discovered that hyaluronic acid had an important function as a moisturiser, volume provider and lubricant in the skin, joint fluid and eyes. With its outstanding properties for cosmetic wrinkle filling and skincare, hyaluronic acid has come to be very popular with plastic surgeons and skin therapists across the world.
