Effect of Sunscreen Application on Plasma Concentration of Sunscreen Active Ingredients: A Randomized Clinical Trial.
This study found that when people put sunscreen on their skin, some of the chemicals get into their bloodstream — and way more than the safety limit set by the FDA. So yes, the claim is right.
Effect of Sunscreen Application Under Maximal Use Conditions on Plasma Concentration of Sunscreen Active Ingredients: A Randomized Clinical Trial.
Scientists tested sunscreen on people using way more than normal amounts, and found that chemicals from the sunscreen got into their blood—way more than the safety limit. So yes, the claim is right.
This study showed that when people use sunscreen heavily, chemicals like oxybenzone and avobenzone get into their bloodstream — and in amounts higher than the safety limit set by the FDA.
