Lasers. Your dermatologist can use a laser to remove the outer layer of your skin, contour areas of acne scars, or lighten redness around healed acne lesions. Various types of lasers are used, depending on whether the acne scar is raised or flat. More than one laser treatment may be required and, depending on the laser used, you may need to several days to heal.
Sunscreen: "Sun exposure during an active breakout can lead to darkening of inflammatory lesions, prolonging their appearance on your skin and making them harder to fade over time," says Dr. Shereene Idriss from Union Square Dermatology, which means it's important to lather on the sunscreen daily — even when it's cloudy. And don't worry about breaking out from a pore-clogging sunscreen; the latest formulas are more innovative and acne-friendly than ever. Elta MD UV Clear Broad-Spectrum SPF 46 is a top derm-approved favorite. It contains niacinamide, which is an anti-inflammatory that helps reduce redness.
All three dermatologists suggested that the best solution for boxcar or rolling scars are in-office procedures. Dr. Day, for instance, suggestedEndyMed Intensif, which uses microneedle radio frequency to remodel the skin by delivering heat into the skin to stimulate collagen and elastin production. For at-home treatments, however, Dr. Day turns to Olay's DIY microdermabrasion kit. It comes with both a foam head and crystal polisher, which claims to exfoliate 7 times better than a typical scrub and thoroughly cleanses the face to prevent future breakouts.
Doctors can treat telangiectasias with a small electric needle, a laser, intense pulsed light, or minor surgery to close off the dilated blood vessels. Usually, multiple treatments are required for best results, and only a portion of the blood vessels improve with each treatment. Not everyone responds the same to these types of treatments, and a physician can help someone decide which treatment is best for his or her skin type, condition, and size of blood vessels.
Post-inflammatory hyperpigmentation is not an acne scar, but a red, pink, brown or tan skin discoloration where acne has previously flared up. It will usually disappear on its own in a year or so. Many skin lightening products claim to help reduce the visibility of these acne “scars." Their active ingredient, hydroquinone, works to slow melanin production and can reduce dark brown marks, but melanin isn't the cause of red and pink acne discolorations. A better option is to use the best foundation for acne prone skin you can find to hide the marks until they naturally fade away.
Exfoliating cleansers and masks: A variety of mild scrubs, exfoliants, and masks can be used. These products may contain salicylic acid in a concentration that makes it a very mild peeling agent. These products remove the outer layer of the skin and thus open pores. Products containing glycolic or alpha hydroxy acids are also gentle skin exfoliants.
