Amazing product!
[This review was collected as part of a promotion.] Love it. It’s my 4th time buying and not only 1, but I buy 3-4 at a time. No white cast. Doesn't feel heavy. More natural products as opposed to the ones in the USA.

Great sunscreen
[This review was collected as part of a promotion.] It goes on easily and doesn’t have a white cast. It feels very hydrating. So far, so good. My friend gave me my first bottle that was P++++ and this one is only P+++ so it’s a little disappointing to have lost a + but I’ll still use it.

Better than other US sunscreens
This Is not as good as the original Version but still good. Mildly greasy and takes more effort to spread over skin than the spf50 PA++++. Smells like other sunscreens available in the US market while the original one had virtually no odor.

Really excited about this sunscreen!
[This review was collected as part of a promotion.] I've been using this product for about two weeks so far and have really been enjoying it. It doesn't leave a white cast on my face, feels very hydrating, and leaves me with a slight glow for a while after application. It's a great final step to my skincare routine.

NOT THE SAME PRODUCT GAVE ME AN AWFUL REACTION
THIS SUNSCREEN IS AWFUL. I ordered it online this past summer and loved it. They have reformulated it completely it is not the same product. i had an AWFUL reaction to this product. as soon as i applied it i noticed it messing with my vision and making it blurry. i then got an awful migraine and threw up.

Silky Smooth
[This review was collected as part of a promotion.] This sunscreen moisturizer makes my skin feel like silk. I use it solely as a moisturizer, forgetting it has the added benefit of being a sunscreen. It doesn't leave a white cast, the formula is very light and much thinner than lotion sunscreen, and it doesn't have a strong smell. I'm never going to use anything else now that I've found this product!

Not the original
Not the original made in Korea version. Still better than most sunscreens but much thicker than the original and also had that "sunscreen smell" that I dislike. Also much pricier than other sellers.

Feels like a moisturizer
This SPF is easily the most comfortable sunscreen I’ve tried because it feels exactly like a lightweight daily lotion. It absorbs easily and leaves the skin feeling soft and protected with absolutely zero white cast. While it’s labeled as non greasy, it definitely leaves a strong glow. If you prefer a matte look or have oily skin, just be aware that the dewy finish is quite prominent throughout the day.

This is the product that convinced me to actually start using some kind of skincare on my face. I’ve always hated how lotions or SPFs feel, but this one actually feels nice and does t take long to dry or absorb, or whatever it’s doing. I apply it after a shower in the morning and it makes my skin feel nice for the rest of the day.

Fantastic sunscreen!
Love this product! Has an adequate SPF 45+ protection, and goes on easily. Absorbs quickly, and doesn’t leave a white haze on my skin. The hydration is great, keeping my skin hydrated throughout the day. Gives my skin a nice dewey look.

Aww
I miss the 50 spf!! But the ones that are sold on your site seem to be knock offs because there is a texture difference

This is a very moisturized sunblock lotion. It is a bit creamy, but overall it is a great sunblock lotion.
