Early verdict · Few reviews so far

What the gurus are saying

This foaming cleanser earns consistent praise for being surprisingly gentle despite its rich lather, with a lower pH around 5 to 6 that supports the skin's natural barrier. The key to getting the most from it is using very little product, mixing it with water in your hands before applying to your face, which creates a full deep cleanse without leaving skin tight or dry. It contains birch sap with amino acids and minerals that help retain moisture, making it feel more hydrating than many Western cleansers.

"This is the Round Lab Moisturizing Birch Cleanser, one I've tried before. This is a great K beauty cleanser and such a good example of a cleanser that is quite different from Western cleansers. [...] This is a true foaming cleanser, and in big contrast to Western products you need so little of it, just the tiniest amount, mixed in your hands with water before it touches your face, and then you get such rich lather, a full deep cleanse that doesn't dry your skin out."

"I finished two Korean facial cleansers, both from Round Lab. The Birch Juice Moisturizing Cleanser and the Round Lab Docto Cleanser. [...] These are both wonderful. The Docto one is creamy and the Birch Juice one is clear and colorless. But they're both super gentle, fragrance-free, nice lathers, wash your face just fine. Rinse off easily. No offensive smells. Really, really like those as my second step."

What the evidence says.

Independent of what the gurus think, this is what the published research supports about the main active ingredients here.

Vitamin C

Topical vitamin C is an antioxidant with reasonable evidence for dullness and uneven tone. It breaks down in light and air, so how a product is formulated and packaged matters as much as the percentage on the front.

Humectants and emollients

Ingredients like these draw water into the surface layers and slow how fast it leaves. The evidence is for comfort, softness and hydration rather than for changing the structure of the skin.
