Most of us didn't get pedicures during the pandemic. But even in regular years, keeping the skin on one's feet and heels soft, supple, and un-ashy requires commitment. "The epidermis is much thicker on the soles of your feet," explains Cheri Frey, a dermatologist based in Maryland. "As a response to the pressure of standing, this skin also sheds less frequently. This, along with friction, can lead to callouses." It's that thickening that makes it difficult for regular foot creams to penetrate and nourish your heels and soles. And that's where foot peels come in. (Drum roll, please.)
