ROUND LAB Birch Juice Moisturizing UV LOCK SPF 45

I really like the ROUND LAB Birch Juice Moisturizing UV LOCK SPF 45. It feels lightweight and moisturizing on the skin without leaving a heavy or greasy feeling. It absorbs nicely and works well under makeup. I also love that it doesn’t leave an obvious white cast. My skin feels soft and hydrated after applying it, making it easy to use every day. Overall, a great sunscreen and I’m very happy with my purchase!

I’ve tried a lot of sunscreens, especially Korean sunscreens, and this has quickly become one of my favorites. It feels much more like a lightweight moisturizer than a traditional sunscreen. It spreads easily, absorbs nicely, and doesn’t leave my skin feeling heavy, greasy, or sticky. The biggest thing for me is that it sits really well under makeup and doesn’t pill when I layer other skincare underneath. I also haven’t noticed a white cast. My skin tends to get a little sensitive and dry, so I really like that this feels moisturizing without being too much.

I am thoroughly impressed by this sunscreen. If you are used to traditional, heavy US drugstore formulas that leave you feeling like you are wearing a chalky plaster mask, switching to the Round Lab Birch Juice UV LOCK will feel like a complete revelation. The texture strikes a perfect balance right in between a lightweight cream and a gel, giving it incredible slip so it spreads seamlessly across the face. True to its claims, it absorbs beautifully with absolutely zero heavy residue or white cast. What really sets it apart is the immediate, wonderfully cooling sensation it gives upon application, leaving the skin feeling deeply refreshed and hydrated rather than suffocated. Because it layers so beautifully, I’ve actually been using it in a hybrid routine: applying a standard heavy sunscreen as a base, and then layering this elegant Round Lab formula on the high points of my face where the sun directly hits. It behaves like a high-end daily face lotion rather than a thick sunblock, meaning it doesn't sting the eyes or feel greasy as the day goes on. For a 1.69 fl oz facial sunscreen, the formulation quality is top-tier K-Beauty. If you have sensitive or dry skin and are looking for real comfort, compliance, and deep hydration under your daily layer, this is a phenomenal investment. Highly recommended!

Round Lab has some great products but this moisturizer with spf is so much better than I was expecting. No white cast. No greasy residue. I have sensitive skin so I’m always very careful with skin products as I break out easily. This product is so moisturizing and works great on its own and even better under my foundation! My hubby uses it too. I will definitely purchase again!

Pretty good overall. It feels lightweight and moisturizing, but I found the finish a little too dewy for my skin. It’s okay, but I expected a bit more.

I’ve tried many sunscreens, but this one really impressed me. It feels more like a lightweight moisturizer than a sunscreen. I applied it in the morning before my makeup, and the picture I uploaded was taken in the evening. My skin still looked fresh, hydrated, and glowy after an entire day. No pilling, no heavy feeling, and it sits beautifully under makeup. It’s one of the few sunscreens that makes me actually look forward to wearing SPF every day. Highly recommended!

Absorbed really well into the skin and does not make me feel like i have anything on my skin even. Although there is a bit of a shine after but it feels like nothing is there. And it definitely is moisturizing as other sunscreens I've used i can see and feel the difference in my skin drying out vs this one.

Didn't realize this is the American version until it was too late....but still works well. Just need to layer a 2nd/3rd time. Less sheen that the original Korean version. Texture is lighter and not as moisturizing but it's pretty good. I still used it.

Amo este producto, lo mejor en protector solar.
