Why does sunscreen damage car paint? Are there other household products that can also damage car paint?

Question

What specifically about sunscreen damages the surface layer of car paint? If it damages car paint, how come it doesn’t damage your skin?

Is it found in both chemical and physical sunscreen?

How come people don’t care about interactions of other skin care products (like moisturizers) with their car paint?
Thank you! I’ve always wondered this since someone warned me not to put sunscreen on near their car.

Answer 1

Fortunately we are not made out of car parts and car paint. The solvents in sunscreen react with car paint, but not our epidermis.
