Thoroughly rub the cream into all skin surfaces, from your head to the soles of your feet. It is important to apply it everywhere on your body, not just where the rash is. Apply the cream between fingers and toe creases, in the folds of the wrist and waistline, in the cleft of the buttocks, on the genitals, and in the belly button. Use a toothpick to apply the cream beneath your fingernails and toenails. Nails should be cut short.
