Exfoliation helps remove dead skin cells that can dull your complexion or clog pores, but too much can lead to irritation, redness, or a compromised barrier. Dermatology experts suggest chemical exfoliants—like AHAs (alpha hydroxy acids) or BHAs (beta hydroxy acids)—over harsh physical scrubs, as they’re more even and less abrasive. The golden rule: start slow, listen to your skin, and treat exfoliation as a gentle nudge, not a full-on attack.
