Exfoliating scrubs or peels are like tough love for your complexion: A bit of abrasion can sends dead skin cells packing and exposes a softer skin underneath. But too much exfoliation can take instigate acne, make skin more vulnerable to irritation and cause rashes, breakouts, bacterial infection and scarring. If feel your skin can usually stand the extra scrub, you should still bypass products with rough particles and opt for ones featuring smooth beads made from jojoba wax (a moisturizing plant oil) or beeswax. Check with you dermatologist, and if your scrub feels too harsh, save it for dry spots like knees and elbows. Moisturize to help prevent irritation, wait a week between exfoliating treatments, and limit at-home peels to once every 2 weeks. If you feel burning (a little sting is normal), immediately rinse with water, apply moisturizer, and toss the peel.
