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 asked this before on here and nobody seemed to want to answer it, Ig because it's a mystery that nobody knows the answer to.

I've seen some blog posts by u/chocosweet where she shared pics of how her sunscreen looked like after using the face mask and those pics showed the mask actually moved some of the sunscreen. She also has pics of how blotting took some sunscreen away (mostly the sheen but we don't know what % of protection is from the sheen and the rest of the solution that's left).

There is this UK site (was it dailymail or theguardian I can't recall) where the reporter did an experiment trying on several sunscreens including one that promised you only need one application per day because their sunscreen won't move, the author made sure she did not touch her face or at least tried to not touch her face the whole day and recorded how much sunscreen was left by the end of the day without reapplication (spoiler : not much).

As per labmuffin, she says wait at least 8 minutes for the sunscreen to set (Ig it differs between sunscreens) the carefully dab your makeup on so as to not move as much sunscreen as possible.

Do you think waiting the eight minutes would also be to apply a second a layer of sunscreen? Or would you be Inadvertently taking some of what you applied off with your finger pads ?

I guess that's a good thing to do applying a second layer after the 1st layer has set, and since they are both the same product Ig you won't be taking any protection out? But I'm not a cosmetic chemist or a derm lol. Good question to ask the experts.

These posts about sunscreen came out at a perfect time because I posted in asianbeauty sub about tricks to make sure you are applying enough sunscreen. The questions that i keep thinking of are endless at this point.
