[Miscellaneous] An Experiment on How Much Sunscreen is Left on Fingers/Puff After Application

Beauty Tips For Body Care
Hey everyone! With the current situation, I recently had some extra time on my hands so I decided to do an experiment.I recently learned that some people like to apply their sunscreen with a cushion puff (ala Fiddy Snails). I personally subscribe to the finger-pat method but have been using the puff occasionally because it gives me a less streaky finish. However, I'm worried the puff might be absorbing some of the sunscreen, which is why Fiddy recommends dispensing three fingers' worth to account for absorption.I still prefer patting sunscreen with my fingers but wanted to quantify exactly how much I'm losing with both fingers and puff.Earlier, I computed that I need around 0.66g of sunscreen for my face based on the 2mg/cm² recommendation. I've simplified it to 2/3 of my pointer finger, which comes out to 0.92g, which is a still a lot more than necessary but not so much as to be wasteful. (These measurements are only for the Purito Unscented sunscreen.)Puff Method:I weighed my unused cushion puff and it came out to 2.52g. I dispensed 0.92g of sunscreen and dotted it all over my thigh. (I had to use my thigh since it's nighttime and I have tretinoin on my face.)I didn't smear it with my fingers but patted it into an even layer using the puff. I then weighed the used puff and it came out to 2.90g. The puff ended up absorbing 0.40g of sunscreen!This is how much the puff absorbed. (It's exactly 0.40g but I accidentally tared the scale.) Pretty significant. When using a puff, definitely use more sunscreen than needed.Finger Pat Method:Again, I dispensed exactly 0.92g of sunscreen and dotted it all over my other thigh. Like with my face, I roughly smeared it with three fingers and patted it into an even finish.. I'm now left with the usual amount of sunscreen on my fingers.I scraped everything off with the scale container until my fingers were clean and weighed the scraped sunscreen. It came out to 0.033g. This is what it looks like on my finger. Pretty negligible.Of course, this might be completely different for you and for other sunscreens. Do what you will with this info. But for now, I'm sticking to the finger-pat method and applying a second layer.I hope you guys enjoyed this little experiment!
