Restylane is an injectable dermal filler made from hyaluronic acid, a substance that occurs naturally in the body. Hyaluronic acid is responsible for adding volume and moisture to the skin, which is why Restylane injections are often used to treat wrinkles, fine lines and other signs of aging. Additionally, Restylane can be used to enhance lips and cheeks for a more youthful appearance. While there are different types of dermal fillers on the market today, Restylane is one of the most popular because of its ability to provide long-lasting results with minimal side effects.   Most patients receive Restylane injections every three to six months to maintain desired effects. However, treatment frequency may vary based on individual needs and goals. It is necessary to discuss your treatment plan with a qualified professional.
