I have found that the best way to help a callus heal fast consists of a two-step approach. First of all, you will need a callus lotion with some of the ingredients mentioned in this article. I personally prefer one with aloe vera, because this ingredient is very healing.
Next, you will need a bandage that is large enough to completely cover your callus. If it is not large enough, it could fall off before your callus gets the benefits from being covered.
After smoothing on the callus lotion, place the bandage over your callus. This will keep the lotion in place while locking in moisture that will soften and sooth your callus.
Repeat this process at least twice a day until your callus heals. You will most likely find that covering your callus as you treat it with lotion will work for you.
