Hyaluronic Acid, or Hyaluronan is one of the newer anti-ageing "miracle" ingredients on the beauty scene. But does anyone actually know what it's doing? How it works? Doubt it... so let me fill you in!
Hyaluronic acid is a biological polymer - a polymer that is found naturally within our bodies. It's found in all types of tissue, but is often concentrated around joints, in the umbilical cord, and in our extracellular matrix. Traditionally, this glycosaminoglycan has been used in medicine for treatment of rheumatoid arthritis, as it helps to restore flexibility and elasticity around the joints.
Essentially, it binds water in the extracellular matrix and holds cells together in a jelly-like consistency. This is why it's been utilized for so many cosmetic purposes! As a filler, it is bio-compatible (your body is unlikely to reject it), and plumps up at the site of injection. In other cosmetic products, such as moisturizers, anti-ageing treatments, even in cosmeceutical lipsticks and blushes, it acts to temporarily smooth and plump the applied surface.
Products with hyaluronic acid include: Hylaform Dermal Filler, Fusion Beauty Sculptdiva Blush, Biotherm Multi Recharge SPF 15 Moisturizer (my favourite!), and many, many more!!
