LOVE IT!
I’ve been really impressed with the Round Lab Birch Juice Moisturizing Sunscreen. The texture is very lightweight and feels more like a moisturizer than a typical sunscreen. It absorbs quickly, leaves no white cast, and doesn’t feel greasy or sticky on the skin. It also layers beautifully under makeup and doesn’t pill, which makes it great for everyday use. My skin feels hydrated throughout the day, and it doesn’t irritate or clog my pores. Overall, this is a great daily sunscreen if you want strong sun protection with a comfortable, moisturizing feel. I would definitely repurchase.

Light weight, NO white cast & great under make up
Super light weight. It goes on smooth, doesn’t have white cast. Soaks into skin easily. Doesn’t burn your eyes in or out of the water. Great under make up too!!

⭐️⭐️⭐️⭐️⭐️ 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.

Top Ranked Korean Sunscreen
This Dokdo (ROUND LAB) sunscreen works so well. It's light and non-greasy and is fragrance free. I'm able to put it under my BB cream once it has set. The price is quite affordable for the quality of the cream. The Korean formulation has additional UVA protection, so I'll be trying to buy that one next.

Honest review
Really solid product and still works with my skin despite the differences in formulation compared its Korean counterpart. It’s a lot thicker than the kr version and smells more like your typical sunscreen alongside the birch sap. Asides all that and spf differences (45 broad spec. and 50+ PA+++), it absorbs pretty well but does leave a slight bit of stickiness and weight to my face which might be a dealbreaker. But overall, I’d recommend it more for dry/combination skin types but still works for oily skin types like myself.👍 8.5/10

Amazing sunscreen
This is hands down the most moisturizing sunscreen I have used. It provides great coverage without leaving a white cast. My skin looks so glowy and feels super hydrated after using this, and it also works well under makeup. Will definitely be buying this one on repeat!

Lightweight, Hydrating & No White Cast — Love It!
I am honestly obsessed with this sunscreen! The texture is super lightweight and melts into the skin beautifully — no white cast and no greasy feeling at all. My skin is combination and this gives the perfect amount of hydration without making me oily. It layers perfectly under makeup and leaves my skin looking smooth and healthy. I’ve been using it daily in my morning routine and it hasn’t caused any irritation or breakouts. The packaging is also super cute and travel-friendly. Definitely a new staple in my skincare routine. Highly recommend if you want a hydrating, elegant sunscreen for everyday use!

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!
