@thedermdad: Ever put on sunscreen or a lotion, spent some time in the sun, and then ended up with an itchy rash exactly where you applied it? It might not be a sunburn. Photoallergic contact dermatitis happens when certain ingredients on your skin react with UV light, causing your immune system to see them as a problem. The rash usually shows up a day or two later and can be incredibly itchy. The tricky part? It often looks like eczema, so it’s easy to miss the real cause. If you keep getting a rash after being in the sun, especially in the same areas, it’s worth getting evaluated. Sometimes the solution isn’t avoiding the sun—it’s avoiding the ingredient. Have you ever seen this before? #dermatology #sunscreen
