PREVELLE Silk is a colorless hyaluronic acid gel that contains a small quantity of a local anesthetic (lidocaine) to provide pain relief at the injection site. Hyaluronic acid is a natural substance found in the human body, which moisturizes (hydrates) and cushions the skin. PREVELLE Silk is naturally broken down by your body over time. PREVELLE Silk is injected into facial skin, using a very fine needle, for correction of moderate to severe wrinkles and folds (e.g. areas around the nose and the mouth). The gel plumps the skin to smooth away wrinkles and folds. Your healthcare professional will work with you to develop a treatment program to meet your individual needs. After the initial injection an additional treatment, or touch up, may be needed 1 to 2 weeks later to achieve the desired level of correction. Over time PREVELLE Silk will be broken down naturally by your body, which is why you may want repeat treatments. In general, repeat treatments are needed within 3 to 6 months to maintain the desired result, but the timing of additional treatment varies from person to person. PREVELLE Silk is approved for lips and under the eye. This product costs half as much as other fillers, but also lasts half as long. This is a great product to use if you are unsure about dermal filler and want to try something that will fade within six months.
