You might think a dermatologist would advise against sun exposure altogether.
“There’s nothing wrong with being outside in the sun,” says Dr. Davis.
Ultraviolet (UV) light is a carcinogen, which is where sunscreen comes in handy.
“Sunscreen can act as a barrier to help keep your skin safe from carcinogens,” Dr. Davis explains.
Here are some key facts about sunscreen to keep in mind:
– Sunscreen can expire, which affects both the active ingredient and the preservative.
– Sunscreen is sensitive to extreme temperatures. Keep it out of direct sunlight and avoid letting it freeze during winter storage.
– People of color need to wear sunscreen.
In summary, everyone over the age of 6 months needs sunscreen — including babies.
