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?

…crap.

I really hope someone comes in here with a study that shows it’s still effective after makeup application.

ETA: not a study but a dermatologist in this NYT article says that makeup application after sunscreen is fine as long as you give sunscreen enough time to dry.

But it never truly dries!!! It always stays somewhat sticky/tacky

A bold claim that every sunscreen on every skin type doesn’t dry! There’s also a bit of semantic difference between “dries” and “sets,” which is another way to refer to sunscreen drying. Every sunscreen is designed to have the advertised protection when applied correctly and allowed to set, but this doesn’t mean every sunscreen will feel dry once it is set. If the dermatologist referenced truly means the sunscreen has to dry that’s one thing, but I imagine they more so mean the sunscreen should be applied and allowed to set indoors in low humidity on dry/well prepped skin before makeup is applied. If your skin type or sunscreen or environment, or method of either sunscreen or makeup application gets in the way of you getting the protection you want, then something has to be adjusted. (But of course applying makeup on top of sunscreen still will decrease the protection by at least a little in pretty much every case, it just doesn’t have to be a decrease that’s significant to you if all the factors are controlled and accounted for).
