Dermatologists have been using glycolic peels on patients for years to help with hyperpigmentation and fine lines, but finding an at-home version that didn't risk leaving your your skin flaky and irritated was hard to come by, says online beauty and fashion editor Amber Kallor. But the Brazilian Peel plunger system (which looks like a syringe without a needle) contains premeasured amounts of the neutralizer and active exfoliating ingredient (glycolic acid). Once both are dispensed and spread over the skin, the acid automatically deactivates after 10 minutes. Kallor says the gel felt tingly and warm on her face at first, but when she rinsed it off with water her skin looked glowy—not red. Game to try this at home? Remember to wear some kind of SPF protection; your skin will be especially sensitive to the sun.
