thanks for contacting HCM, One common (and usually effective) way to battle acne is with antibiotics, either in a pill or applied to the skin. Antibiotics work by destroying bacteria that have accumulated in the hair follicle to the point of damaging it. Photopneumatic therapy: This treatment combines an intense pulsed light (IPL) laser with a gentle vacuum. It works by removing excess oil and dead skin cells from clogged pores. It is approved to treat blackheads, whiteheads, and some other types of acne. It cannot treat acne nodules or cysts. conclusion is optical treatments with lasers...possess the potential to improve inflammatory acne on a short-term basis...optical treatments for acne today are not included among first-line treatments.Both proper topical treatment, as well as isotretinoin (Accutane) for people with severe acne, can provide more predictable, consistent, and complete clearing. regards
