Round Lab Birch Moisturizing Sunscreen SPF 50+ PA++++ 40 ingredients
It's not the most hydrating sunscreen I've ever used and its texture is reminiscent of a slightly thick serum or an emulsion. It feels good on my skin and did not break me out. No white cast whatsoever, didn't require any blending in, and applied without a tacky finish. One of the sunscreens with the least pilling I've tried, but did very very very slightly pill on the area around the eyes after a Show more
Stung my face
I wanted to love it because so many people are praising it, but it just wasn't for me. I don't why, but it stung my face, and I'm not sure which ingredient is causing it (I don't have sensitive skin, but I used it alongside BoJ ginseng essence and iUnik centella calming gel cream in the morning, maybe the ingredients in the products react w each other?). It also makes me look oily, Show more

this sunscreen stung my eyes super bad. even when i took care to avoid my eye area, it still burnt. left my skin red and irritated looking.
Worst product from COSRX
Not suitable for oily skin because the amount of silicone in it causes a lot of pilling and it's horrible to use with other products. Not suitable for sensitive skin, it triggered irritation and redness on my face after one week of using it.
