Restylane® is a dermal filler made of hyaluronic acid, a natural substance that already exists in the human body. The hyaluronic acid also creates volume and fullness in the skin, giving it a healthy, youthful appearance. When Restylane® is injected directly into areas where the body’s collagen has been weakened, it smoothes and minimizes facial lines. It can also be used in some types of scars, including depressed acne scars. In addition, skin texture is improved and has a softer and more even tone. Restylane® may be used to correct moderate to severe facial wrinkles, such as the lines from your nose to the corners of your mouth and for lip enhancements in patients over 21 years of age.
