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.

Oily, formula feels different than the one I bought in Korea
I bought this in Korea last year and loved it. I finally ran out so bought two more online. I don’t know if the formula changed, but this one makes my skin feel way more oily and slick. I will be returning

Different Formula
Why must America take every product and ruin it to add it to the market. Smells like sunblock, greasy oily feeling, white cast. Not the same product whatsoever, a waste of $25. Don't buy this if you're used to the original!

Feels great on my skin
This has been the best sunscreen I've used so far, and I've tried so many different brands & products. My skin is very sensitive so I was hesitant to try something new, but I'm really glad I did because I never have to look for another sunscreen again!

Best Moisturizer
Used to be the best moisturizer ever, but then they changed the formula when they entered the American market and I cant do it. The smell is the same as every other sunscreen and its overwhelming.

Great product
I really have enjoyed using the Birch sunscreen. While it comes out of the tube white, it quickly melts into the skin and becomes invisible. It gives my skin such a glassy look when first applied and then mattes as it sets in. It works great under makeup. I would highly recommend!
