@4complexion: Your sebum has a UV problem. Squalene is a big part of your natural oil oxidises in sunlight into something genuinely pore-clogging. So the “SPF breaks me out” is often backwards: it’s the protected skin doing the clogging. #cosmeticchemist #skincarehacks #sunscreen #oilyskin #SkinCare101
The more i learn about science, the less i like the sun😅
