"Psoriasis is the overgrowth of the top layer of skin cells in the epidermis, and is thought to be brought about by an immune reaction in the skin," says Mona Gohara, MD, a board-certified dermatologist based in Connecticut. She adds that it can happen at any age, and tends to show up in the form of a flaky, itchy rash.
“While it’s not curable, it is treatable, which means there is no reason for anyone to be walking around with a skin condition that makes them feel uncomfortable," says Dr. Gohara. Derms tend to prescribe treatments and suggest topical steroids to help tone down the inflammation, but to treat psoriasis scaling at home, all you need is a gentle (repeat: gentle!) chemical exfoliator.

"When people have thicker plaques on their skin, use of an alpha hydroxy acid, such as lactic acid, or a urea-based product can really go a long way to help to get those scales off the skin," says Dr. Gohara. Lactic acid is famous for being one of the most gentle exfoliants out there, while urea acts a keratolytic and a humectant, getting rid of thick dry skin build-ups while hydrating and softening the skin.
Though scrubbing at your psoriasis patches can make them worse (it leads to something called the Koebner Phenomenon, in which flare-ups appear in areas of trauma), gently exfoliating them with an acid can help remove some of the plaques. "Keep It simple," says Dr. Gohara. "Cleanse, use a gentle exfoliator over the plaques if need be, and moisturize every night."
