Restylane can be used for smoothing out folds and wrinkles, lip enhancements and shaping facial contours. The most common areas are the glabellar lines (between the eyebrows), the nasolabial folds (from the root of the nose to the angle of the mouth) and the lips, although other sites can also be treated. Very superficial or very deep wrinkles may be difficult to correct. Please consult your physician for an assessment.
