What is it? Restylane Silk is a transparent hyaluronic acid gel that is injected into patients’ lips and wrinkles around the mouth. Hyaluronic acid is a protective and lubricating gel that is produced naturally by the body.

How does it work? A doctor injects Restylane Silk in a patient’s lips and wrinkles around the mouth one or two times as needed over a period of two weeks. The product works by temporarily adding volume to the lips and smoothing wrinkles around the mouth. The effect lasts for about 6 months.
When is it used? Restylane Silk is used in patients over the age of 21 with thin or very thin lips. The gel temporarily adds volume to the skin which may result in larger lips and may smooth wrinkles around the mouth.
What will it accomplish? Restylane Silk may help increase the volume of patients’ lips and may smooth wrinkles around the mouth.
