We tapped two board-certified dermatologists to get the scoop on exfoliation and how to properly exfoliate for your skin type. While this is no miracle fix and certainly won’t scrub away your dark spots after one use, over time you may notice these marks become lighter in color thanks to sloughing away that dead skin. “Physical exfoliation uses something abrasive,” says board-certified dermatologist Amy Ross, M.D. Often, these types of exfoliators can get a bad rep for being too harsh and causing the skin to become stripped and dry when used on the face. On the other hand, chemical exfoliants use chemicals to break apart and remove dead skin cells. “These are commonly alpha-hydroxy acids (AHAs),” Ross says. “The strength of the acid can be adjusted to create safe, mild, and effective exfoliation for all skin types.” Like all skin care products, it’s important to know exactly what type of skin you have and any sensitivities that you should be mindful of before choosing which exfoliant to use. Keep reading to learn exactly how to exfoliate based on your skin type. Ross suggests choosing a physical exfoliant that’s mild and gentle and blended with hydrating ingredients like oils, butters, or waxes to smooth and protect the skin. But what’s most important is taking note of how your skin feels after exfoliating. If your complexion is red, irritated, or inflamed, you’ll want to choose a gentler formula. For best results, stick to exfoliating once a week until your skin is able to tolerate it without irritation.
