does what it says [SEP] out of work right now so cannot afford my every week pedicures i have supination where i walk on the outside of my feet which causes excessive callouses to grow on my heels i always use a pumice stone after every shower but have had to have the manicurist use the heel razor now our state has outlawed the use of the razors i find using this callous remover does help a lot however if i go too long without getting my heels scraped the right heel splits open and wellit is very uncomfortable needless to say do not use the product if you have any sores or cuts on your feet i used rubber gloves to apply then tied my feet up with plastic bags and let sit minutes then i used a foot rasp while product is still on the feet was amazed at how much callous the product removed afterward i washed real well i think this product is good for those times you cannot get a pedicure and you want to do it at home however if you do have excessive callouses and feet problems you might want to discuss options with a podiatrist as this product may not do well
