SOAK Autonomic damage can result in abnormal function of sebaceous glands and absence of sweating. This means dry skin. Sun damaged skin and scarred skin may also be excessively dry. Dry skin is less resilient and more prone to burns and trauma than is moist skin. Dry skin rapidly absorbs water during soaking.
Plain water is all that is needed.
Usually, there is no need to include medication in the water, though many people add aqueous cream. Medication such as potassium permanganate for treatment of fungal infections, can be added if desired. It is safest to advise the water at room temperature. Hot water may burn the limb with heat impairment. Ten to twenty minutes soaking will soften all the callus making it appear white and spongy and will adequately hydrate dry skin and subcutaneous tissues.
