Dermatologists Warn on Misleading 'Oral Sunscreens' as Sunblocks

Imagine your skin is like a house, and the sun's rays are like little hammers.

Topical sunscreen is like a shield that stops the hammers.

Oral sunscreens are more like helpers inside your house that try to fix the damage if some hammers get through.

They have antioxidants, like vitamins, that help your skin.

But doctors say they aren't as good as sunscreen you put on your skin, and shouldn't be used without a doctor's advice.

You can also get these helpful things from eating fruits and vegetables, so you don't always need a pill.
