Skin Care Tip of the Day: The key in this age of product overload is to read labels. New compounds are turning up in cleansers, moisturizers and sunscreens all the time. It is hard to keep up, especially when some ingredients go by more than one name. By law the first ingredient listed on the label should have the highest concentration in the formula, but every ingredient is listed, even when there are only trace amounts of it in the product.
