As an oily skin girly, how well the sunscreen stays on throughout the day is the most important factor for me. And roundlab doesnt disappoint! The sunscreen applies smoothly and gets absorbed into the skin quite easily (not a lot of rubbing required). After it's applied, it doesnt clump, flake, or pill throughout the day, even if im sweating in the clammy office.

The only thing to note is that roundlab is rumored to clog pores, especially for oily skin girlies. I haven't really observed anything? I still have acne, but I seem to get it regardless, and it doesnt seem to be linked with Roundlab, so that correlation is inconclusive. Also, the tone up sunscreens run more white casty on purpose.

Speaking as a medium-toned East Asian girly, the medium tone up is a little too pale for me, I tend to use the regular Birch sunscreen. Im using the medium up for my neck, since I'm convinced my neck is darker than my face even without any foundation on, so Im self-conscious of that
