Dr. Scholl's Liquid Corn & Callus Remover, 0.33 oz – Fast-Acting Foot Treatment for Corns & Calluses with Protective Cushions | Relieves Pain from Shoe Pressure & Friction – Ideal for Daily Use, Walking, Running & High-Heel Wearers

Softens callous after just two uses (and a few days wait) although, I will probably use up to four to get it baby soft. I did not experience any peeling as of two back to back applications. Only issue, the applicator sucks! It is a plain jane stick, It does not hold any product… you have to constantly dip it back in multiple times and apply on the same tiny area to get a full coat.
