It should be at least 30. What about Oxybenzone? Does it give you cancer due to factor of absorption through skin layers? I am so disappointed to see that most of the drugstore brands lotion contain Oxybenzon if this has been proved to be correct. Beauty Brains please help! Is it true that SPF 15 is not enough?

It's SPF 15, smooth and easy to apply, nice and moisturising but not greasy at all. I have yet to find a higher SPF lotion to use on my body - mostly I just put up with greasiness!

That said, I know most of my training is highly biased(especially from the luxury brands vs. the derm brands), which is why I was so pleased to find your blog to balance out my training, and I now subscribe to much of cosmetics design for up-to-the-minute advances and controversies(thank you!). Getting to my point, one of the trainers from the derm brand said screens with chemical screens(mexoryl xl, tinosorb, helioplex) included are applied as the first layer in your daily regimen because they have to soak into the top layers of the skin so they can absorb UVA/UVB rays, and that if you're using a strictly mineral screen(like those formulated for sensitive skins) with titanium dioxide and/or zinc oxide as the only sunscreen ingredients, you apply those after the rest of your skincare. Intuitively, this makes sense to me, but I look to you guys for some more specific answers regarding the truth of this. Also, do you have any input on the new use of jet-milling for the mineral screens? It creates a much more appealing product because it spreads easily and disappears quickly, but i feel like i wouldn't use enough to achieve the full SPF on the package? Maybe though the increased surface area makes a lot less product a lot more effective?
