Exfoliating removes the dead skin cells that leave your face dull, flaky, and rough, and it helps clear clogged pores. Done right, it makes a visible difference. Done too often or too hard, it strips and inflames the skin, which is the more common mistake. The skill is doing enough and no more.
Two Ways to Exfoliate
There are two types, and they work differently. Physical exfoliation scrubs dead skin off with grit, a scrub, brush, or cloth. Chemical exfoliation uses acids, like salicylic or glycolic acid, to dissolve the bonds holding dead cells on. Chemical exfoliation sounds harsher but is often gentler and more even than scrubbing, since a good scrub is easy to overdo and can cause tiny tears in the skin.
Which One to Use
For most people, a chemical exfoliant is the safer choice. Salicylic acid suits oily and acne-prone skin because it gets into the pores. Glycolic acid suits dull or rough skin and works on the surface. Harsh grainy scrubs, especially rough ones, are the easiest way to damage your skin, so if you use a physical scrub, pick a fine one and a light touch.
"More exfoliation is not better skin. Past a certain point it is raw, red, over-stripped skin. Two or three times a week does more than every day ever will."
How Often Is Enough
This is where most people go wrong. Exfoliating two or three times a week is plenty for most skin, and sensitive skin may want just once. Daily exfoliation, or scrubbing hard every day, strips the barrier and leaves skin red, tight, and irritated. Start slow, once or twice a week, and only increase if your skin handles it well.
The Signs You Are Overdoing It
Over-exfoliated skin is common and looks like the opposite of what you wanted. Watch for redness, tightness, stinging, unexpected breakouts, or skin that feels tight and looks shiny-raw. If you see these, stop exfoliating completely for a week or two, focus on gentle moisturizing, and let the barrier recover before easing back in more slowly.
Moisturize and Protect After
Exfoliating leaves fresh skin exposed, so aftercare matters. Moisturize after exfoliating to comfort the new skin, and be strict about sunscreen, since freshly exfoliated skin is more sensitive to the sun. Skipping sun protection after using acids is a fast way to irritate and damage the skin you just uncovered.
