"Retinoids work over time by continuously increasing cell turnover which in turn helps fade hyperpigmentation," says Dr. Idriss. Dr. Shah agrees, noting that Retin-A helps with acne marks by causing your skin cells to "divide more rapidly and pushing out cells with discolored pigments." Since retinoids make your skin super-sensitive to the sun, it's best to not only wear SPF, but to also apply a treatment like RoC Retinol Correxion Sensitive Night Cream before you go to bed.


Worried moisturizer will make your acne worse? Think again — it can actually help improve your skin. “If the skin surface is dry and dehydrated, the oil glands tend to overproduce oil and this can make acne worse,” Dr. Weiser says. “Hydrating the skin surface can re-balance oil glands and help control acne and improve healing.” When buying a moisturizer, she recommends looking for a lightweight, oil-based product that won’t clog your pores. Dr. Levin likes Differin Soothing Moisturizer because it's "a great lightweight pH balanced moisturizer you can use in combination with acne topical treatments."
Acne (acne vulgaris, common acne) is a disease of the hair follicles of the face, chest, and back that affects almost all teenagers during puberty -- the only exception being members of a few primitive Neolithic tribes living in isolation. It is not caused by bacteria, although bacteria play a role in its development. It is not unusual for some women to develop acne in their mid- to late-20s.
