Are there "toxins" in your sunscreen? A dermatologist explains what you need to know.

Labor Day weekend may be over, but summer isn't yet — and even as temperatures cool down, it's important to keep protecting your skin from the sun. But do you need to be worried about toxins in sunscreen?

Experts say concerns around sunscreen doing more harm than good are often misguided — and potentially dangerous if it leads to people skipping SPF altogether. 

"We know the sun and UV rays result in photoaging, sun spots, wrinkles and increased risk of skin cancer. Sunscreen helps protect against these effects," explains Dr. Samer Jaber, a board-certified dermatologist at Washington Square Dermatology in New York. "When you are outside, please practice sun safe behaviors."
