Slathering on moisturizer enhanced with sunscreen can save you an extra step in your skin care routine. But beware: Sunscreens are one of the top five allergens in moisturizers. Not every sunscreen causes allergic reactions, and not every person is allergic to sunscreen. To complicate things even further, you can't just avoid sunscreen altogether. It's necessary to protect your skin from the harsh effects of the sun, including cancer caused by too much exposure to ultraviolet (UV) rays. Yet, there are few things to keep in mind about sunscreens to help you find the one suited for your skin.
Certain substances in sunscreens are potential allergens. Here are some to watch out for:
- para-aminobenzoic acid (PABA)
You'll also want to keep an eye out for padimate A and O, which are related to PABA, because they can cause contact dermatitis in some people. If you have a sunscreen allergy, your dermatologist can help you find your ideal formula.
