Many people know that taking certain medications or getting a chemical peel or laser treatments will make your skin more sensitive to the sun, but there are many other, less obvious culprits that will have you seeing red in the extreme if you mix them with the sun’s rays. Common pain-relievers like Aleve, Motrin and Advil; herbal supplements like St. John’s wort and dong quai; fruits and veggies like lime, parsnips and fennel; and even alcohol are just a few of the potentially dangerous items that can react with the sun to cause anything from a mild sunburn or a nasty rash to an increased chance of skin cancer.
