InStyle talks with N.Y.C.-based nail pro Ji Baek about how to get dry feet primped and perfect for the sandal season. “Feet need to be constantly exfoliated and hydrated to stay healthy,” Baek says. Try using a foot scrub or slough during every shower and afterward, apply a thick cream with glycolic acid while feet are still damp. If skin is still extra-dry, try soaking your feet in a milk bath for 15 minutes a couple of times a week. Tweezerman's Glide Away foot file is a great tool for getting tough skin smooth again.
