⭐️⭐️⭐️⭐️⭐️ Love love LOVE this sunscreen
I’ve always hated sunscreen — eye burning, bad smell, greasy feel, looks bad under makeup. This one completely changed that for me. This sunscreen feels like a lightweight glass skin moisturizer, not sunscreen. No eye stinging, no strong smell, and it actually makes my skin look and feel better. I let it dry down about 10 minutes or more before applying makeup. The best part is I love it so much that I want to apply more...which has never happened before with SPF. I don’t even need a separate moisturizer underneath. If you hate sunscreen, try this one. I’ll definitely repurchase. Trying their moisturizer next to replace my CeraVe.

Absolute BEST Sunscreen on the Market!
This sunscreen is my new favorite! It’s so lightweight and hydrating. Zero streaking and does not feel oily at all (a concern with all my past sunscreens). I’ve tried many other popular sunscreens like Anessa, Dr. G, EltaMD, Etude, Isntree, and more and RoundLab is by far the best. If you’re debating whether to get it I’m telling you to full send it!

Lightweight Daily SPF With No White Cast
ROUND LAB Birch Juice Moisturizing UV LOCK SPF I bought this sunscreen for a trip to Mexico and used it every morning, especially around my nose and cheeks where redness usually shows up. It went on easily and felt light on my skin, and I was relieved that it did not leave a white cast, even in bright sunlight. After putting it on, my skin looked more even and felt soft instead of dry or tight, which I appreciated in the heat. It stayed comfortable on my skin throughout the day without irritation. At night, it came off easily with my gentle everyday cleanser.

Moisturizing
I have super dry, eczema prone skim and this has been super moisturizing in the winter months. I used to be a big fan of the isntree hyaluronid acid sunscreen, but this is so much more moisturizing. I apply my sunscreen pretty thick and have not noticed any white cast. No irritation noted. Note that this will probobaly be too heavy for those with oily skin. For those with dry to normal skim, give it a try!

Lightweight and makeup friendly - everyday sunscreen
I’ve been using the Round Lab sunscreen for a few weeks now and it’s honestly perfect for everyday wear. It’s super lightweight and blends in effortlessly with no white cast at all, which is a huge plus, especially for deeper skin tones like mine. It wears beautifully under makeup. It feels smooth on the skin, and actually makes my foundation apply more evenly. It’s almost like a hydrating primer in that way. The only downside for me is that it does make me look a bit oily after a few hours, especially in my T-zone. If you have oily or combo skin, you might want to use a mattifying primer or blotting paper throughout the day. Other than that, it’s a great sunscreen. Gentle, effective, and comfortable for daily use, just wish it had a slightly more matte finish. I would still recommend this, especially for dry to normal skin types!

I loved it 😊
I loved this sunscreen because it combines high protection with hydration, which isn't always easy to find. Its texture is lightweight and absorbs quickly, without leaving a greasy feeling or white residue, making it very comfortable to wear all day long. I loved it from the first day I used it and I will definitely continue buying it.

Feels so good on my skin
I love the texture and how thick it is. Even when it’s overcast or raining, I still put this on at the end of my morning routine to “lock” my moisturizer in. Works great as a primer before applying makeup. I feel like it evens out and blurs my skin.

this is the american version. put photos for comparison.
this is the American version, it is entirely inferior to it’s Korean counterpart . It is significantly thicker, smells like sunscreen and leaves your face feeling and looking greasy for about an hour. The Korean one has little to no smell, is thinner, and leaves your face feeling moisturized. On the left of my hand is the American version, right is Korean. I also took a photo 20 minutes after lathering them on my hand. This is still a good sunscreen but there is no reason other than availability to use this over the other.
