Medicated cream for black and white head?

Serious Rx: You've already got acne scarring. This would not have happened if you'd gotten cared for by a scientific physician. Acne is a serious, chronic, non-lifestyle-related disease, a major personal and professional liability, that can be managed by 21st century care. With many blackheads, a topical retinoic acid derivative is a good choice; since scarring's present, likely an antibiotic also. Go for it.
