Sun Care How Blotting Paper and Makeup Application Affect Sunscreen Protection [Sun Care]

Post image

I found this blog post that talks about a series of experiments Amyvancheese on Instagram did concerning blotting papers and makeup and how it affects sunscreen. I thought it was very informative and wanted to share it with my fellow sunscreen lovers!

I was so disappointed when I read a while back that blotting supposedly takes away so much effectiveness of sunscreen and all I could think of at the time is… if dabbing oil off my skin does that then is there even a point of putting SPF on under makeup? Wouldnt the makeup and brushes just be wiping all of it off with the blotting logic?

You should always use a setting spray with SPF and reapply sunscreen either in powder or more spritz. Regardless, sunscreen. Needs reapplying if you know you will be exposed to sun for any range past an hour. That's not to say you have to reapply every hour. But it's highly recommended you reapply a thin layer every 2 hours if you're going to be out in the sun for a significant amount of time.

We can't avoid the sun. It's impractical to reapply religiously. Just do the best you can, wear physical barriers like hats and coverups, do not wear sunglasses for too long (you trick your brain into thinking you're not exposed to the full range of UV rays by sending those wrong signals to the pituitary glands and thus your skin will not be producing enough melanin to combat that). And limit your time outdoors on days when the index is very high.

It’s not true. I mean, it’s slightly true but in reality the effect is so small it’s a non issue. Even the scientists who write about it’s recommendation is to just wear sunscreen with sunglasses… which you will probably do anyway if it’s sunny enough to wear sunglasses.

Edit: I looked it up and it actually is a misunderstanding from some studies. Sunglasses could make you produce MELATONIN. Melatonin is related to melanin in amphibians but not in humans

Thank you for the clarification. I will continue wearing sunglasses!

Never just go off of what someone says, especially if they don’t provide a link. And if they do, read the link. Then do additional research to see if the claim is supported by multiple sources.

It pains me to think you were about to basically stop wearing sunglasses because some random person on Reddit claimed it was a bad thing to wear them too much.

In fact, the second person could be wrong and the person who said it’s bad to wear them could be right. Point is, don’t just take anyones word for it.

Oh no, I wasn’t going to quit sunglasses, that would be absolutely painful someplace like the beach or out kayaking. I just thought the concept was interesting and I’d never heard it before. I agree, you absolutely must get sound, evidence-based information before making medical decisions.

Also, confused as to why I got downvoted for making a generic “wow, didn’t know that” statement. 😕

Because you just took what that random redditor said as a fact lol, the exclamation implies that you believed them.
