Restylane Silk has recently been approved for release in the United States! It's the first and only FDA-approved product  for subtle lip enhancement and the smoothing of wrinkles and lines around the mouth in patients over 21 years of age.

HOW DOES RESTYLANE SILK WORK?
Just like the other members of the Restylane family, Restylane Silk is a clear gel formulation of hyaluronic acid — a sugar that is naturally present in your skin.
