There are several low-level light devices designed as at-home acne remedies on the market — but do they really work? Some, like the Zeno electronic "zit-zapper" are FDA-approved as acne remedies, but reviews with these products are typically mixed. Even the best acne treatment won't work for everyone, as the severity of the acne, types of acne and quality of the device are all factors. Ask your dermatologist for a recommendation if you're considering purchasing an at-home light device to treat your acne.

Common acne, known medically as Acne Vulgaris, is generally caused by hormonal changes in the body, and its onset usually can be found in teenage years when puberty rears its head. Acne is directly attributed to the rise of androgen hormone levels. The production of these hormones rise when a child begins puberty, and is the reason much acne is prevalent in adolescence. As androgen levels rise, the oil glands sitting directly underneath the skin enlarge and produce increased levels of oil, also known as sebum. When pores are filled with excessive sebum, it can cause surrounding skin cells’ walls to rupture and create a breeding ground of P. acnes bacteria. As the sebum attempts to push out of the pore, it can attach to this infectious bacteria and dead skin cells, causing a blockage that begins the formation of a pimple. According to Medical News Today, dermatologists purport that almost three quarters of 11 to 30-year-olds will deal with acne at some point, but acne breakouts can continue on into adulthood, and have been observed in patients in their fifties.
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. The biggest downside is they're harsh and can sometimes be too much for sensitive skin. For an elegant OTC option, try Dr. Dennis Gross Skincare Ferulic Acid + Retinol Brightening Solution.

Dr. Day says another product ingredient to look out for is retinol to "help minimize and even avoid scarring." Dr. Chiu suggests this particular SkinMedica product because it "induces new collagen formation, which can soften acne scars, as well as unclogs pores for acne prone skin while bringing pigment to the surface with its exfoliative properties." Start using it twice a week and you'll notice fine lines start to fade as well.
The SUPERMUD® Clearing Treatment was developed to address common skin concerns, which include blemishes, redness, scars, razor bumps, and in-grown hair. The potent mud formula supports skin’s natural oil balance, while a proprietary blend of six acids (glycolic acid, salicylic acid, lactic acid, mandelic acid, pyruvic acid, and tartaric acid) works to help minimize pores and create clearer skin. Activated-X charcoal lifts away dirt and other skin congestions, resulting in a refined, healthy-looking complexion.

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.
