The truth about SPF

[HenHenriette]

That's true about UVB rays, though. But the spf number on a sunscreen stands for UVB protection, and the UVA protection is only promised to be at least a third of UVB protection. (If the sunscreen is broad spectrum, ofc.)
So if you use spf 30, UVA is at least 10. Spf 50 would be at least 17. That's almost doubled the protection compared to 30, so I would say spf 50 is more worth it for that fact.
Please prove me wrong, but I've read that more than once. The first time at a brochure at my doctor's office.

can you do a video on how to erase under eye wrinkles, please?

I always buy 50+, didn't know 30+ is just a percentage less

i think the fact is the reaplication time, not the protection, you have to reaplicate faster the 30 spf, so the 50 one it takes longer. 🤗

What kind of sunscreen is that you are using ?

[KPOPCOREEE]

My Sun block contains broad spectrum and it ha uv filters for prevention against uva and uvb rays it is UVA And UVB and the spf is 60 and the most important ingredient in it is Methylisothiazolinone Phenoxyethanol 😅

It's not about protection you get it's about what you don’t. Spf 30 means 3% rays are penetrating inside in your skin and spf 50 means 2℅ you are getting 1.5x more protection
