The key to this callus time machine? Chemical exfoliation via lactic and salicylic acid, which encourages calluses and dry skin to literally peel off.

According to the Cleveland Clinic, “underneath those calluses and rough, dry patches is smoother, softer skin” — but you have to get to it. Rather than just hydrating or moisturizing, these masks exfoliate your feet, helping you get rid of the tough, dead skin, revealing fresh, happy feet.

To do the treatment, first soak your feet in water for 10-20 minutes, apply and wear the mask for 90 minutes, then wait a week or two for the peeling to start. “...On day 10, the horror show began! Just as others described, tons of skin began to peel. It peeled from places that I didn’t realize I had skin to spare,” shopper Breanna wrote. “...Seriously, I am creeping up on 50 years old, and my feet look like they did in my 20s.”

According to the brand, the strawberry option gives extra hydration while the peach boosts new skin cells. (If you don’t favor fruity scents, the lavender option (not on sale) is meant to help reduce inflammation,the jasmine option focuses on reducing dryness, and aloe + green tea has citric acid, intended to help speed up the peeling process.)
