Treatment for Boxcar and Icepick acne scars.

For your kind of scarring, I have had success with a combination of subcision and spot application of strong chemical peel solutions such as TCA or phenol. With subcision, you would expect bruising and with the spot chemical peel application, redness or pigmentation that can last for weeks to months.

Microdermabrasion would not give you significant improvement in the kinds of scars you are describing. The fractionated CO2 lasers (Fraxel repair and Deep FX) can give you significant improvement if you have the 7-10 days of available down-time.

Good luck.
