If you’re at all concerned about sunscreen safety, a mineral based (zinc oxide and/or titanium dioxide) version is generally agreed upon as safe.
The evidence is convergent. Multiple independent sources reach the same conclusion, the underlying mechanism is well-characterized, and even the field's most cautious voices treat it as worth doing.

Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.

if you are somebody who is concerned about the chemicals in sunscreen most every dermatologist or chemist who works on sunscreens will tell you well mineral-based inorganic sunscreens are going to be your safer option
probably best of year towards a mineral-based sunscreen if you are concerned at all about the chemicals in chemical based sunscreen wear a mineral based sunscreen
very few folks are concerned about mineral-based inorganic sunscreen so if you want to use sunscreen as many people do and you want to make sure that it's not an endocrine disruptor and it's not a neurotoxin or something else that's been raised for some of these chemical-based sunscreens well then find a sunscreen that has 25% less zinc oxide and or titanium dioxide
I tend to recommend mineral sunscreens because they don't have any of that data they haven't for the last 30 40 years they're considered safe
for several reasons in the original set of sunscreens that were approved by the FDA that came out in 1999 there wasn't enough data to look at biologic effect efficacy internal organ involvement Etc fast forward 20 years and we've gathered a lot more information about these chemical organic compounds there is an amazing 2020 study that looked at absorption of chemical sunscreens when they're applied onto the skin they looked at absorption with single application and they looked at absorption over 4 days of application now the study they applied a little bit more than you know Real World Experience would but even with single application they saw blood plasma absorption of these chemicals that were 100 to 500 times greater than the upper threshold defined by the FDA now the question exists okay what does that mean is this healthy is this not healthy is it neither that's still up for debate but in looking at the more recent literature and looking at the chemical structure of these compounds a lot of these are phenolic compounds meaning they they have one or two usually two Benzene Rings attached together and they they look very similar to one another there's been a lot of basic science animal study and retrospective human studies in the last 2 or three years that suggest that some of these chemical compounds particularly o o benzone particularly octocrylene particularly um Octon oxinate um that can have endocrine disruption or affect the nervous system because they mimic a lot of biologic phenolic compounds and a lot of biologic hormones if you actually look at the structure of oxybenzone it looks very similar to the structure of bisphenol a which has been now banned in a lot of the lining of plastic bottles why because of the same concept now the data is not 100% one way or another but there's enough smoldering evidence that makes me think H we should reinvestigate this and in fact the fda's proposed final order in 2021 changed these chemicals from Grace generally recognized as safe and effective to not Grace because of these concerns
one is I use a mineral based sunscreen it is less likely to be absorbed through the skin it has UVA a and UVB protection it also is more environmental friendly

mineral sunscreens especially those with non- nanozinc oxide are probably the safest options when it comes to protection from the Sun and not disrupting your hormones with these other chemicals
Until there is more data, mineral-based sunscreens are the way to go.
I said mineral-based sunscreens rather than chemical-based sunscreens are the way to go.
