But the side effects of targeted breakout cream treatments aren’t always worth it. “So many products instruct consumers to use benzoyl peroxide spot treat red bumps and pustules. I don’t recommend it,” says Dr. Lawrence Green, board-certified dermatologist and assistant clinical professor of dermatology at George Washington University. Such high concentrations of benzoyl peroxide cause added irritation and inflammation to already sensitive skin, so with this in mind, we cut kits that included spot treatments.
Since benzoyl peroxide is often prescribed in office for handling cystic acne (it kills acne-causing bacteria within the hair follicle), it was the first choice among dermatologists I spoke to as an over-the-counter treatment. There are a couple of different options out there from face washes to topical creams to bodywashes, but dermatologist Ross S. Levy, of CareMount Medical — the director of dermatologic surgery at the Albert Einstein College of Medicine — says that typically “the benzoyl peroxide (5 to 10 percent) topical creams or gels are more effective than the cleansers or washes.” The only danger with benzoyl peroxide to be mindful of is that it will stain clothing and pillowcases. Clean & Clear’s Persa-Gel, which contains 10 percent benzoyl peroxide, is one of Gonzalez’s go-to recommendations for treating cystic acne at home.
Dermabrasion is an effective therapeutic procedure for reducing the appearance of superficial atrophic scars of the boxcar and rolling varieties. Ice-pick scars do not respond well to treatment with dermabrasion due to their depth. The procedure is painful and has many potential side effects such as skin sensitivity to sunlight, redness, and decreased pigmentation of the skin. Dermabrasion has fallen out of favor with the introduction of laser resurfacing. Unlike dermabrasion, there is no evidence that microdermabrasion is an effective treatment for acne.
In most cases, acne products need to be used for at least 30 days before you can begin to ascertain its efficacy. Some skin and acne types may see noticeable results in a few days and end up totally clear in just a few weeks. Others may take several weeks to see the slightest change, or need to have their regimen adjusted as their skin adapts. Treating acne can often be a months-long process.
Risk factors for the development of acne, other than genetics, have not been conclusively identified. Possible secondary contributors include hormones, infections, diet and stress. Studies investigating the impact of smoking on the incidence and severity of acne have been inconclusive. Sunlight and cleanliness are not associated with acne.
