Most, if not all, nonprescription moisturizers help smooth skin and replenish moisture in the outermost layer of the skin. But products with claims that go beyond the basics probably aren't worth the extra cost. Higher cost doesn't correlate with a more effective product.

Tips

On the face or other acne prone areas, use products designed specifically for the face. Other moisturizers may clog pores.

Extra dry skin - Look for a product with petrolatum as one of the top three ingredients. Products containing glycerin, lactic acid or urea can provide an extra boost. However, they may sting on application, especially for those with cracked skin.

Sensitive skin - Almost any moisturizer ingredient can cause skin irritation or allergy, but fragrances, dyes, lanolin, and the preservatives parabens and formaldehyde tend to be the most common offenders.

Moisturizers work best when used daily and immediately after a bath or shower. Hydrated skin is healthier and better shields the body from germs and allows dead skin cells to shed without becoming scaly or flaky.
