Sometimes stubborn acne just won't budge even with benzoyl peroxide, salicylic acid, tea tree oil or other common treatments. It might be time to try something a little unorthodox—calamine lotion has been used for years to treat chicken pox and poison ivy, and it can also help shrink blemishes, thanks to its zinc oxide content.
Wash your skin gently (don't scrub) and thoroughly with a natural, preservative-free soap. Rinse with lukewarm water, and dry your face with a clean towel.
Apply calamine lotion to a cotton swab and dab a little bit directly onto pimples. Apply more than one coat if you like. Let the lotion dry and leave it on overnight.
Wash your face as usual the next morning.
Apply the lotion as needed every night until the blemishes disappear. You should see a marked improvement in about a week.
