Why Dermal Fillers? Compared to other wrinkle correction methods, dermal fillers allow greater precision in wrinkle correction, and can more effectively treat medium to deep wrinkles. They do not cause any loss of ability to contract your facial muscles. Compared to other scarring treatments, dermal fillers allow more effective treatment of boxcar scars, deep divots and icepick scars. Compared to other methods of changing the shape of your face (such as your nose, lips or cheeks), dermal fillers offer the advantage of being non-permanent and creating a generally more youthful look. Rhinoplasty carries its own major risks, and facelifts often create an overtight look. Dermal fillers allow you to experiment with different facial changes in a non-permanent way. I only use a naturally-derived fillers (the most widely known is hyaluronic acid) which has a smaller risk of causing an allergic reaction. Depending on the type of filler and where it is injected, the effects can last anywhere from six months to two years.
