Round Lab formulates clean, high-quality skincare products from Korea that improve skin conditions regardless of skin type and age
4.5
Round Lab earns strong reviews for effective, elegant sunscreens—especially Birch Juice Moisturizing Sunscreen—that wear invisibly under makeup, hydrate without white cast, and suit sensitive skin, while oil and foam cleansers clean thoroughly without stripping. Reviews also flag drawbacks: certain formulas feel thicker or slightly sticky, the Korean and U.S. versions perform differently, some users experience mild irritation or breakouts with toners, and several skincare items deliver minimal visible results.

Honestly, not impressed. I think that you can find much better Milky Toners out there. As you can see from my picture it’s a very watery consistency for a milky toner. It does feel good on the skin but I don’t find that it gives much or does much in terms of moisture or improving my skin’s appearance.
I’m not sure this is doing anything. This is the first product I’ve tried from Round Lab. I have melasma and post acne spots that I have been trying to fade. It’s an interesting consistency that feels very light and like a gel. There is the “capsule” suspended in the clear gel that seems to be more of a creamy, yellow texture. Everything mixes together when you apply it. It feels nice and soothing on my face but I don’t think it’s really doing much and I haven’t noticed any other benefits.

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.
