Treatment of acne scars: For those patients whose acne has gone away but left them with permanent scarring, several options are available. These include surgical procedures to elevate deep, depressed acne scars and laser resurfacing to smooth out shallow acne scars. Newer forms of laser resurfacing ("fractional resurfacing") are less invasive and heal faster than older methods, although results are less complete and the procedures may need to be repeated three or more times. These treatments can help, but they are never completely successful at eliminating acne scars.
"Hyperpigmentation is an increase of melanin, which is the substance that colors the skin," says Dr. Sobel. Hyperpigmentation often clears up on its own. However if you want to speed up the process, you can use topical treatments with ingredients like retinol, vitamin C, and kojic acid, which can help brighten skin overall. We like Sunday Riley Sleeping Night Oil ($105, sephora.com) and InstaNatural Vitamin C Serum ($17, amazon.com). The most important thing is to stay out of the sun to keep the dark spots from getting even deeper in color.

First thing's first: prevention. "Getting on a good skincare regimen, avoiding picking, popping, or traumatizing the skin, and protecting it with SPF so it does not darken are important ways to avoid acne scarring," dermatologist Annie Chiu advises. For day-to-day coverage, try this SPF 45 option from Dr. Jart. It's a four-in-one primer, moisturizer, sunscreen, and treatment serum that evens out skin tone from within and offers mild coverage.

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.
