Slathering oil on your skin might seem counterproductive, but that’s not actually the case here. “Tea tree oil will reduce inflammation and help calm acne-prone skin and works as well as 5 percent benzoyl peroxide without the irritation,” says Elizabeth Tanzi, M.D., founder and director of Capital Laser Skin Care in Maryland. Try Evanhealy Tea Tree Gel Cleanser ($10, evanhealy.com) in place of your regular face wash.
