I only used it once, but I think it's pretty good. I know it only has SPF 30, but I feel like it's better than nothing—definitely better than not putting on sunscreen. It's really good for people with oily skin. So far, this is probably the best sunscreen I've ever used. It's actually lightweight. I've also tried other Korean sunscreens like Beauty of Joseon and Round Lab, and I think this one is the best. I might repurchase once I finish it.
