Retinol is a vitamin A derivative, which the skin absorbs and converts to retinoic acid. Retin-A is the prescription form. "Topical retinoids are fortunately one of the most effective treatments for acne, and also happens to be a highly effective antiaging ingredient, because of its collagen-building properties," Dr. Tzu notes.

Ablative lasers deliver an intense wavelength of light to the skin, removing thin outer layers of the skin (epidermis).

There you have it! As with any skin condition, it's best to consult your regular dermatologist to see which option is best for you.

Probably the most useful lifestyle changes one can make is to never to pick or squeeze pimples. Playing with or popping pimples, no matter how careful and clean one is, nearly always makes bumps stay redder and bumpier longer. People often refer to redness as "scarring," but fortunately, it usually isn't permanent. It's just a mark that takes months to fade if left entirely alone.
