Collagen injections and fat grafting are employed to improve deeper facial wrinkles and are also used for lip enlargement. The collagen used in Dr. Natale’s office is human as opposed to bovine variety. The advantage to human collagen is that it is far less likely to result in an allergic reaction and does not require skin testing prior to use. Improvements obtained with collagen injections are temporary, lasting a maximum of six months.

Fat grafts, obtained by liposuctioning other areas of your body can also be used to improve lines and wrinkles and are also used for lip enlargement. Fat grafts are fragile, and much of the material injected will atrophy. The remaining fat will, however, last longer than collagen but should not be considered permanent.
