Be warned, though. This is a treatment you have to set some time aside for. (Some would say it’s the perfect thing for a period of staying at home.) The masks themselves vary in how long they should be left on. Some are as short as an hour but no longer than overnight. A quick piece of advice from us: Always soak your feet in warm water for a short time before applying any of these masks to help the process along. The exfoliation part, however, involves the mask’s ingredients working slowly over a period of time, sometimes up to a week or 10 days, before any results are seen. Then, the top layer of your skin sheds, much like a snake, leaving behind baby-soft soles underneath.
So if you’re ever planning to use one in preparation for a specific event in the future, be sure to leave at least a week beforehand. And no matter how convinced you are that it hasn’t worked, maybe just leave it another day before heading out for a walk in your sandals. Trust us, though—the results are worth it.
