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.

The picture on this product page shows SPF 50 but title says SPF 100... lol. This is for the SPF 100 version, and holy moly it's the shiniest sunscreen I have tried yet to date. I really wanted the SPF 100 because there are so few of them on the market but it's just so immediately eye blindingly shiny and greasy. When I used this my oily skin didn't even stand a chance at being slick free. Also it burns the eyes so much.
But despite all that, the SPF did protect me against tropical sun during my vacation even though it felt so greasy using it so it gets 1 star back.
