Not terrible, but I won't be repurchasing
Size: 3 Fl Oz (Pack of 1)
2.5 stars from me. I've been using this as a near-daily sunscreen for 3 months. I like it better than some other sunscreens I've used, but I'm dragging my feet to use the rest of the bottle haha. And I definitely won't repurchase. I'm hoping there's a magical sunscreen out there waiting for me that I love...
Pros: It doesn't leave a whitecast, it doesn't pill, it presumably blocks the sun!
Cons: If I put it anywhere near my eyes it will get in them, I will taste it in my mouth if it's applied anywhere near my mouth, it stays shiny throughout the day, I feel like I'm not allowed to touch my face (This may just be all sunscreens though)

Lightweight glowing hydrating sunscreen
really love how this sunscreen feels so light and smooth on my skin without leaving any white cast at all. It blends in quickly and gives a natural, hydrated glow skin with hyaluronic acid and collagen. My skin feels moisturized all day, and it doesn’t get oily or greasy even after hours. It’s gentle enough for my sensitive skin and hasn’t caused any irritation or breakouts. it’s a great everyday sunscreen that keeps my skin protected and fresh.

Lightweight Sunscreen with Great Hydration
This sunscreen feels lightweight on the skin and blends in nicely without leaving a heavy or greasy feeling. I like that it gives SPF 50 protection while also adding hydration, so it works well as part of a daily skincare routine. It leaves the skin feeling soft and comfortable.
The formula sits nicely under makeup or can be worn alone for a natural look. It absorbs well and does not feel sticky, which makes it easy to reapply when needed. A great option for everyday sun protection with added moisture.

Best sunscreen
I really like this sunscreen. It feels lightweight on the skin and blends in easily without leaving a white cast, which is a big plus. The texture is smooth and moisturizing, but it does not feel oily or heavy. It works well for daily use, especially under makeup, and feels comfortable even on sensitive skin.
The SPF 50 PA++++ protection gives good peace of mind for everyday sun exposure. I also like that it has hyaluronic acid and collagen, so it feels more like skincare than just sunscreen. Overall, it is a great affordable Korean sunscreen and I would definitely recommend it.
