What is oral sunscreen? Viral beauty trend or a genuine solution?

Traditional sunscreens are applied directly to the skin in the form of lotion, cream, gel, or spray. It creates a barrier on the skin that absorbs and reflects harmful UV rays. 

Oral sunscreens are supplements rich in antioxidants that enhance free radical neutralization, which helps combat cellular damage and premature aging from harmful UV rays. 

Unlike traditional sunscreen, oral ones boost the body's natural defense against UV rays. Traditional sunscreen lays on top of skin, while oral ones protect from the inside out. 

It might be more convenient and less time-consuming than traditional sunscreen, as it doesn't require re-application. It provides body antioxidants and boosts natural defense. 

It still requires tons of research and is a topic of debate about whether it is enough to protect skin from damaging UV rays.
