Foundations, moisturizers may not contain enough sunscreen for daily protection

The Wall Street Journal reports that most foundations and moisturizers that contain sunscreen may not have enough of the product to provide protection lasting all day.

What’s more, the sunscreen found in make-up products and moisturizers may not protect against both types of ultraviolet rays, often failing to protect against UVA rays.

Finally, dermatologists point out that people need to wear at least the amount of sunscreen found in a shot glass to protect exposed skin, and that amount of coverage would be difficult to get unless moisturizer and make-up is frequently reapplied in large amounts.

The article also describes changes cosmetic manufacturers will have to make in order to meet new Food and Drug Administration requirements for sunscreen SPF labeling claims starting in June.
