There are two types of exfoliators: physical exfoliators and chemical exfoliators. They both get the job done, but they go about it in different ways.
How Physical Exfoliators Work
Physical exfoliators work by physically removing the cells with visible scrubbing agents.
“Physical exfoliators contain finely ground grains or nuts that, when rubbed on the skin, help remove dead skin cells,” says Dr. Farris. You might exfoliate with these products using a cleansing brush, a mitt, an at-home microdermabrasion device, or just your fingertips. “It increases circulation and gives your skin a bit of a glow. It also leaves skin feeling smooth and silky,” she says.
She recommends U.SK Under Skin Perfect Rice Scrub (Farris is a board member for the line), Philosophy Microdelivery Exfoliating Facial Wash, and St. Ives Gentle Smoothing Oatmeal Scrub and Mask.
How Chemical Exfoliators Work
Chemical exfoliators, on the other hand, work by dissolving dead skin cells with acid, says Farris. There are two main acids to look for in chemical exfoliator products: alpha hydroxy acids (AHAs) and beta hydroxy acids (BHAs).
You can also use an exfoliating product that combines the two acids (Farris likes SkinMedica AHA/BHA Exfoliating Cleanser).
Farris says the benefits of these chemicals go above and beyond exfoliation. “These multitaskers lighten pigmentation, reduce the appearance of pores, soften fine lines and wrinkles, and even improve breakouts,” she says.
