After my acne fade away they leave behind scars and some kind of red spots? now my question is how to get rid of these red spots. & black heads please

A few options: First, if the scar is red or swollen, use an over-the-counter cortisone cream to calm the skin. You can also do laser therapy or filler therapy, within one to three sessions, laser skin resurfacing using fractionated laser technology can even out the skin surface and increase new collagen formation to help fill in acne scars. Wear plenty of sunscreen, sun makes the scars worse. Hope this helped :].

Prevent new ones: The spots heal with time and can't be remedied. Acne needs to be treated scientifically. If you have scars, you didn't get proper care when you were a teen. I'm sorry. If topical benzoyl peroxide has failed, with with your physician. If blackheads are numerous, a retinoic acid derivative may be the next rx to add. Acne is a serious, chronic, non-lifestyle-related disease.

Many options: Blackheads can be treated with exfoliants such as salicylic acid, glycolic acid, or procedures such as microderm, glycolic peels. Red discolorations can be treated with various laser (ktp or pulsed dye lasers) or ipl treatments.
