There are so many fillers these days that it is often difficult to know which is best. Acne scars are a specialized treatment area and thus the choice is often times easier.
The two basic requirements should be that the filler plumps the skin well enough to correct the scar and second that it lasts long enough for prolonged correction.
My personal favorite is Radiesse (Calcium hydroxlapetite). This filler plumps, provides immediate correction and last approximately 9-16 months.
Microroplet silicone is another excellent alternative. This is a specialized technique performed by only a limited number of physicians. It is a permanent filler and must be used with care.
ONE IMPORTANT NOTE ABOUT ACNE SCARS: there are many different types of acne scars (ice pick, box car, rolling type scars), and they must be approached using different techniques and combinations of techniques including lasers, acid peels and then fillers as a final therapy.
