Acne should be optimally managed with your dermatologist before starting cosmetic treatments. A treatment often not covered by insurance, but shown to be effective for acne in many people is photodynamic therapy (PDT). Once the acne condition is stable, there are several treatment options available, depending on the goal. For resistant comedones, microdermabrasion and chemical peels are valuable. Persistent red spots or marks can be improved with the Palomar MaxG laser. Surface irregularities, depressions, and textural changes (scars) can be treated with the Palomar 1540 or 2940 erbium lasers and microdermabrasion.
