Hi before starting off directly with a laser treatment I would suggest you to consult a dermatologist . A qualified dermatologist will be able to assess your scar type. Acne scars can be of different types. Fractional CO2 laser works for most but some dieant. In which case prior or along with laser few small dermatological procedures loke subcision, punch elevation , derma roller and dermabrasion may be needed. Regards.
