butter LONDON was founded by Sasha Muir, a British innovator looking to blend high-fashion nail color with toxin-free formulas. Her line of beauty products eschews such toxic ingredients as formaldehyde, toluene, and DBP. While Muir is known for her colorful line of 3 Free Nail Lacquers, she also has a line of pedicure products. Try the Rock Off Callus Remover. While filing your heels may tone your arms, it does little to consistently control hard, thick, yellowing soles. When combined with Rock Off, however, filing easily exfoliates away the skin cells that have been broken down by the callus remover, leaving you with supple soles that will last throughout the year.

• Removes skin calluses on your feet
