The Restylane family of products is a brand of hyaluronic acid dermal fillers, which includes Restylane Silk, Restylane Lyft, Restylane, Restylane Refyne, and Restylane Defyne. Each is a clear gel formulation of hyaluronic acid specifically formulated to act like your body's own naturally produced hyaluronic acid. Each Restylane product is designed for a specific purpose. Restylane Silk is the first FDA-approved product specifically designed for subtle lip augmentation and the smoothing of wrinkles around the mouth. It is composed of a gel that is smaller and smoother than other Restylane products, resulting in a softer, more precise result — ideal for restoring and enhancing the lips. Additionally, Silk is administered via an ultrafine needle, which is designed for improved accuracy and precision. Restylane Lyft is approved for cheek augmentation and the correction of age-related midface contour deficiencies, as well as the treatment of moderate to severe facial folds, such as the nasolabial folds (smile lines). Lyft is the first and only FDA-approved filler with the ability to provide fullness to the cheeks, as well as restore lost volume in the midface area. Lyft contains 0.3% lidocaine, which is added to reduce discomfort during treatment. Restylane is used to add volume and fullness to the skin to correct moderate to severe facial wrinkles and folds, such as the lines from your nose to the corners of your mouth (nasolabial folds). Restylane is also indicated for lip augmentation. NEW Restylane Refyne integrates with your skin to help smooth out the lines that run alongside the corners of your mouth (nasolabial folds and marionette lines) and the flexibility you need for natural-looking movement and expressions. NEW Restylane Defyne is designed to act like your body’s own hyaluronic acid to help smooth out deeper lines around your mouth (nasolabial folds and marionette lines) while letting you look more natural through a range of facial expressions. Restylane products are approved only for patients over the age of 21.
