Restylane is a dermal filler that is made up of hyaluronic acid and has been approved by the FDA to restore volume and fullness to the skin and to lift and smooth out wrinkles and fine lines. Restylane is very safe and natural, and is free of animal proteins. It is often used to treat the glabellar lines, which are between the forehead, and the nasolabial folds. This treatment can also be used to restore or add volume and shape to lips.
Studies have shown that Restylane will usually last for six months, but if retreated in the same area within 4-5 months can last up to a year or even longer. Another reason people choose Restylane is that the results are visible right away.
