ROUND LAB ROUND LAB BIRCH JUICE MOISTURIZING CLEANSER

What is this product?

A Korean water gel face wash from ROUND LAB, sold in one 150 ml tube from the brand's own storefront as the cleansing step of its Birch Moisture line. The label is a mildly acidic surfactant wash by construction: water leads, an acrylates crosspolymer and a salt form the thickening pair, and six surfactants across the amino acid, sultaine, amphoteric, taurate, alkyl polyglucoside and isethionate types do the removal, with no sulfate ester, no soap and no oil phase. One entry carries a printed concentration, a birch sap at position eight with 10,000 parts per million beside it, and the humectant side adds a sodium hyaluronate, a hyaluronic acid and a glyceryl glucoside, all of them below the surfactant block in a product that is rinsed off. A citric acid at twenty five is the pH adjuster and no pH figure is printed anywhere. Two third party test documents are reproduced on the brand's own image and both name this product: a domestic primary irritation summary with a 32 person panel and a no irritation verdict, and a German tolerability certificate with study number 2309183394 and 30 subjects. The four efficacy panels are weaker: three are photograph pairs with no figure or control arm, the fourth publishes a 5.18 percent headline over bar values of 16.93 and 17.81, and both footnotes name one institute, one window and one 22 person panel without naming the tested product. No fragrance entry appears in the twenty six, so the fragrance flag reads none, but two volatile plant oils are printed at seventeen and eighteen and a chamomile flower oil and a pine leaf oil are what a person avoiding essential oils would need to see. No English ingredient column and no usage direction appear on any surface read. No lived use reports were collected.

What makes it different?

The surfactant system is what separates this record from its own line and from the two landed rivals read for it. Six surfactants sit at positions three, four, five, six, twenty one and twenty three, spanning amino acid, sultaine, amphoteric, taurate, alkyl polyglucoside and isethionate chemistries, with no sulfate ester and no soap anywhere in the twenty six entries. The brand narrative does not separate it: the birch sap with its 10,000 parts per million figure, the glyceryl glucoside and the vitamin plus hyaluronic pairing are printed in two sibling products of the same line as well, so those are line conventions rather than this product's own ground. Two documents do give it an evidence base the rest of this page lacks, a domestic primary irritation summary and a German tolerability certificate, both naming this exact product and both carrying panel sizes. The trade-offs sit on the same label: a chamomile flower oil and a pine leaf oil at seventeen and eighteen that no sentence on the page mentions, a saponin bark extract and a sweet wormwood extract that the copy also never names, four efficacy panels whose footnotes name a panel of twenty two and no tested product, and a mildly acidic positioning with no pH figure printed anywhere.
