After placing the lemon on the callus, secure it in place with a bandage or cloth. This will ensure that the lemon remains in contact with the callus for an extended period, typically overnight. Wearing a sock over the bandage can help keep the lemon in place and prevent any leakage of lemon juice, especially if you’re treating calluses on your feet.
While you sleep, the citric acid in the lemon works to break down the thickened skin. The acid gently penetrates the layers of the callus, loosening the bonds between dead skin cells and making them easier to exfoliate. This process is not only effective but also gentle, as it avoids the use of harsh chemicals that can sometimes irritate sensitive skin.
