Catapulted into mainstream beauty by Charlotte Cho of Soko Glam, the double cleanse is now a well-known two-step cleansing method. You know the drill. First, you use an oil-based cleanser on dry skin, rinse that off, and follow up with a water-based cleanser. The first step gently breaks down makeup, sebum, and sunscreen, while the second step washes away sweat and dirt.
