What to use for dry itchy skin, that's good and is over the counter?

Moisturize: There are lots of moisturizers available otc. Some people like them thicker, others prefer thinner like a lotion. Whatever you use should have minimal fragrance or coloring. It's a good idea to moisten the skin before you apply to help lock in moisture. Topical Hydrocortisone can help with some itching but if this is a big problem you should have a dermatologist take a look.
