The adaptable, single-use smoothing adhesive finishes the scraper's job by erasing the rest of the callus. Designed to eliminate calluses in just 15 minutes, the De Si Jolis Pieds treatment from Yumi Feet provides a simple, effective and cost-effective callus control solution for all beauty professionals. Very easy to use. 1- Application of De Si Jolis Pieds patches. After putting on protective gloves, apply De Si Jolis Pieds patches to the calluses on your feet. 2- Patch wrapping. The patches should be kept in place for 15 minutes and wrapped in stretch film to promote the action of the treatment. 3- Removal of calluses. After removing the first patch, remove excess dead skin using the duo feet utensil (scraper side). 4- Moisturize and nourish the skin. To complete the treatment, apply AfterCare post-care moisturizer to the foot.
