Round Lab earns strong reviews for effective, cosmetically elegant sunscreens and gentle cleansers; the brand is good, with multiple users calling the Birch Juice Moisturizing Sunscreen a top favorite for no white cast, quick absorption, and seamless wear under makeup. Weaknesses surface around occasional stickiness or thicker texture, potential irritation for sensitive users (especially to birch), and formulas that differ between Korean and U.S. versions.

Ive purchased two products from Roundlab, the birch SPF and toner. The SPF feels awesome, I loved using it on hot summer days, its super light, didnt break me out at all and felt great. The toner also feels awesome, although when I first started using it directly on my skin (patting it in after my cleanser) I started to have a few breakouts that I think this might have caused, so now I use it on a cotton pad some mornings instead of splashing my face with water, or after cleansing in the PM and it seems to be all good.

I liked the roundlab SPF sunscreen - please be advised that as of August 2025, Kbeauty brands are following a new USA law that they need to fomulate a USA ingredient approved version, so of it says "broad spectrum" it doesn't have the Korean sunscreen in it and the formula may be different. That being said, this one original was great. I prefer ones with more cooling ingredients.

I bought the Round Lab sunscreen as a replacement for my beloved Beauty of Joseon which recently had a reformulation for the US version. The Round Lab sunscreen is good but not perfect. The price is appealing for a product of this quality. The scent isn't noticeable (a plus!). The real drawback for me is that the the texture is a little bit thicker than my preference and I feel it leaves a slightly sticky residue while drying. I'm happily using the bottle I bought, but I'll look for other options before I repurchase.

Round Lab Mugwort Calming Cleanser is perfect for sensitive skin 🌿. It gently cleanses while calming redness and irritation with mugwort and CICA ingredients. The creamy texture lathers softly without drying out the skin. It leaves my face feeling fresh, clean, and balanced every time!

This sunscreen feels super lightweight and gives a nice, natural tone-up effect — perfect for no-makeup days. It blends easily without looking too white or chalky on my skin. I also love that it keeps my skin moisturized throughout the day without getting greasy. Great choice if you want sun protection with a soft glow! ☁️✨

جربت كريم الترطيب من Round Lab بخلاصة عصارة شجرة البتولا، وبصراحة كان من ألطف المنتجات اللي استخدمتها لبشرتي. ترطيبه عميق لكنه خفيف، وبيمتص بسرعة من غير ما يترك أي طبقة دهنية. مناسب جدًا للبشرة الحساسة، بس لو بشرتك دهنية جدًا ممكن تحسي إنه ثقيل شوية في الصيف🤍

Round Lab Vuce Moisturizing Sunscreen offers great hydration with SPF 50+ protection, perfect for dry skin needing extra moisture. It feels lightweight and absorbs quickly without a sticky residue. However, it might not be the best choice for oily skin types. 💙💦🩵

This cleanser is super gentle but still gives a deep, refreshing clean—perfect for daily use. It doesn’t strip my skin or leave it tight, and it works great even on sensitive or acne-prone skin. A simple, soothing staple in my routine🌊🧴💙


This sunscreen feels like a light moisturizer—it hydrates and protects without any white cast. It’s perfect for sensitive skin and layers beautifully under makeup. One of my go-to daily sunscreens for a dewy finish.

The cleanser has worked well so far. It’s cleaned my face without drying it out or leaving a residue. I also started using the moisturizing cream and it feels nice on the skin. I bought them online but recently found out that they started selling some items at Target so that’s convenient!

I’ve tried Round Lab and I’m pretty happy with what I’ve used so far. The oil cleanser is a standout. I seriously love the scent, and it melts away makeup and sunscreen gently without stripping or irritating. The toner has been gentle and comfortable on my sensitive skin though I haven’t noticed a dramatic transformation in tone or clarity. I do appreciate how calm and stable my skin feels after using their products and plan on trying more from the brand.

High quality skincare - never leaves my skin feeling striped, and is veryyyy hydrating! Love the cleanser, it foams really nice, takes off makeup well and a little goes a long way which is wonderful!

I fell in love with ROUND LAB the first time I tried their Korean-formulated Birch Juice sunscreen—so I had to check out the U.S. versions! ROUND LAB Birch Juice Moisturizing UVLOCK (SPF 45, chemical): Not bad, but not quite the soothing, elegant finish of the Korean original. Different filters meant a but more redness than I am used to, for me. ROUND LAB Birch Juice Mild-Up UVLOCK (SPF 50, zinc): This one, on the other hand, was AMAZING! I tried it out for a few days and couldn't figure out why my skin looked so much more clear and less red than usual. Turns out that topical zinc is fantastic at soothing red irritated skin, and it make my complexion look SO good in a matter of days. Like, I could have mistaken this for a redness/blemish treatment if I didn't know it was a sunscreen. This is definitely my go-to.

I bought the sunscreen at Olive Young in Seoul, which came with a cleanser. I really like the texture of the sunscreen, which really does not leave any oily film or white streaks. It works very well under make up and I love that it's scentless. It's a very reasonable price and works better than some expensive brands out there. The cleanser lathers up well but is nothing too special.

Round Lab Birch Moisturizing Sunscreen is all the rage in Korea as one of the top sunscreens. I finally got my hands on one, and, as someone who’s tried at least 15 different sunscreens, this is in my top two! I’m normal to slight combination skin, and this sits SO nicely on my face. The texture is like a light lotion and isn’t greasy at all. My skin soaks it up, and I think it’s the best in terms of how well my skin absorbs it. There’s no white cast, and it isn’t overly dewy or shiny on the skin. I bought mine in Korea at Olive Young, but they also have a US website. One of my favorite products of 2023!

Best quality so far for affordable skincare. I wasn't inclined to have a full skincare routine but since i start working night shift my skin needed something to cope and this company keep giving !
Their birch juice moisturizing sunscreen is the best face SPF I've tried in a long time. I'm someone who really can't stand the smell of sunscreen in general and it's very difficult to find a truly "unscented" sunscreen that actually works. I highly highly recommend this one! On top of that, the consistency is super hydrating and sits really well under makeup. Their sheet masks are also very high-quality and come in different formulas for different skin types and concerns.

Their products are worth the money, you should try it, especially the cleanser.
the oil cleanser is the best i’ve used! it needs to be emulsified with a touch of water, and is gentle on my sensitive skin. i usually finish off my routine with the fresh soy cleanser after to rehydrate my skin.
Their signature sunscreen absorbs quickly and leaves my skin lightly moisturized. There's no typical sunscreen odor or stickiness. It dries to matte. I bought my first tube in May and just finished it in November.
