WTH?
Right here’s the deal: every little thing is product of chemical substances. Water? A chemical (H20). Olive oil? Manufactured from chemical substances. Your physique? Hey, you’re product of chemical substances, too!
Fact bomb: if it’s product of matter, it’s a chemical.
If chemical-free sunscreens existed, you’d get an enormous, fats bottle of… nothing! Heck, you wouldn’t even get the bottle. That’s product of chemical substances, too.
So, why are individuals speaking about chemical-free sunscreens?!
By some means, within the skincare world, chemical-free has develop into synonymous with pure. Right here’s what this implies for sunscreens:
What Are Chemical-Free Sunscreens?
Once more, there are NO chemical-free sunscreens. However, for the sake of readability, I’ll let you know what individuals imply with this expression and maintain utilizing it for the remainder of the article.
Chemical-free sunscreens are sunscreens that comprise solely pure UV filters. There are solely two round:
- Titanium dioxide
- Zinc oxide
P.S. Titanium Dioxide and Zinc Oxide are minerals. A greater time period than chemical-free sunscreens is mineral sunscreen.
WARNING!
If we need to be choosy (and I do), the right time period for sunscreens that comprise pure UV filters is “inorganic”. Why?
In science, something that comprises carbon known as “natural” and something that doesn’t is “inorganic”. These two filters don’t comprise a drop of carbon. They might have a pure origin, however they’re inorganic. Confused a lot?
I personally don’t suppose the time period inorganic sunscreen will catch on anytime quickly – particularly when individuals affiliate pure with natural. I’d relatively name them chemical-free sunscreen even when it’s incorrect. Finally, this fashion we’re all clear on what we’re speaking about.

Are Chemical-Free Suncreens Safer And Extra Efficient?
It relies upon. In the event you’re simply on the lookout for broad-spectrum safety, any sunscreen that protects each from UVA and UVB rays gives you that – whatever the origin of their UV filters.
However if in case you have delicate pores and skin that will get simply irritated, chemical-free sunscreens are a a lot better choice for you. Why? Two causes:
- They’re gentler on the pores and skin: Avobenzone, oxybenzone & co are well-known for inflicting irritations and allergy symptoms, particularly for individuals with delicate pores and skin. Titanium dioxide and zinc oxide hardly ever do. In accordance with a research printed in Contact Dermatitis, oxybenzone is likely one of the most typical sunscreen allergens(Rodriguez, E., et al., 2006).
- Fewer UV filters: You often want 4 or 5 artificial UV filters to offer enough solar safety. The extra UV filters your sunscreen has, the upper the prospect considered one of them will set off a foul response. Zinc oxide, alternatively, protects you from the complete UV vary. A research from Photodermatology, Photoimmunology & Photomedicine concluded that zinc oxide is probably the most secure and least irritating UV filter accessible (Draelos, Z. D., 2016).
P.S. For sure, UV filters aren’t the one problematic ingredient for delicate pores and skin in sunscreens. Watch out for perfume, important oils, and harsh preservatives, too.

Or if you would like a light-weight texture, search for a sunscreen that makes use of nanoparticles (these are controversial, so it’s exhausting to discover a sunscreen with this expertise).
Are nanoparticles protected?
- Research counsel that nano-sized titanium dioxide and zinc oxide don’t penetrate wholesome pores and skin. (Supply: Toxicological Sciences, 2013).
- Nevertheless, they need to by no means be inhaled, which is why spray mineral sunscreens must be prevented.
Chemical-free sunscreens are getting higher, however they’re not nonetheless as nice to make use of as “chemical sunscreens”.
