moisturizer to the heels.
Products containing ingredients such as urea, lactic acid, or salicylic acid can be particularly helpful for thick, dry skin. For a simpler approach, petroleum jelly or a thick, fragrance-free moisturizer can help reduce water loss and keep the skin soft.
Massage the product gently into your heels and, if comfortable, wear a pair of clean cotton socks overnight. This can help keep the moisturizer in contact with the skin for longer.
Consistency is key. An occasional treatment is unlikely to resolve long-standing dryness.
