After having bad acne i am stuck with acne scar and dark spots, what product should i use?

Acne scars and spots: In general, I have found the best results for the scarring using an erbium fractional laser. That said, a series of tca peels often yields great results at a much lower price, but longer time is required. The dark spots can likely be treated with ipl or at least mitigated with a "lightening" agent like hydroquinone. Kind regards, mark johnson.
