@sarahcnutrition: Chemical sunscreen ingredients can show up in your bloodstream after a single application. The FDA’s own pharmacokinetic study confirmed it in 2019. That matters more for women 35+, whose hormone systems are already under enough pressure without a daily dose of endocrine-disrupting UV filters. Mineral sunscreen works on a completely different mechanism: non-nano zinc oxide sits on top of skin and reflects UV rather than absorbing it and converting it to heat. It’s this physics that makes it safer. I’ve been using Baie Botanique’s SPF 50 (25% non-nano zinc oxide, plus sea buckthorn, hyaluronic acid and vitamin C and E for barrier support) and I love both the protection and the texture. Check the active ingredient on your own sunscreen. If it’s not zinc oxide or titanium dioxide, you’re coating yourself in something your skin wasn’t built to process. #ad #partnership #spf50 #mineralsunscreen #skinhealth
