Restylane®is a cosmetic dermal filler that replaces lost volume and restores youthful contours to the skin to smooth away moderate to severe facial wrinkles and folds, such as the lines from your nose to the corners of your mouth (nasolabial folds). Restylane® is made from hyaluronic acid that has been modified slightly to last longer than the body's hyaluronic acid. In the human body natural hyaluronic acid provides volume and fullness to the skin. Restylane® is a minimally invasive treatment and is approved by the FDA. Restylane® is injected directly into the skin in small amounts by an ultra-fine needle. Results are immediate and last about six months.
