ROUND LAB ROUND LAB BIRCH JUICE AMPOULE

What is this product?

A 50 ml watery ampoule from a Korean brand's own storefront, where the whole product detail area is images and the statutory ingredient block had to be read out of one of them. Its 39 printed entries carry ten hyaluronate-family forms, which is exactly the count the brand advertises, spanning fragmented, native and crosslinked types, plus a birch sap at position 7 with a printed level of 10,230ppm, the only level on the label. There is no oil, no butter, no wax, no silicone, no fragrance entry, no essential oil, no denatured alcohol and no exfoliating acid anywhere in the list. The brand publishes a 72-hour instrumental hydration curve with an untreated control, three depth readings, two irritation studies both naming this exact product, and a patent number in full. It also runs a 100 percent satisfaction banner that its own footnote identifies as questionnaire agreement on twenty one people, and a seven-second absorption figure with nothing behind it. No usage instruction and no pH figure appear on any surface.

What makes it different?

Two things separate it inside its own line, and both are counted rather than asserted. First, the hyaluronate stack: ten hyaluronate-family entries against one to eight on the six line siblings whose records were compared, and the ten span fragmented, native and crosslinked forms rather than repeating one type. Second, the evidence: a 72-hour instrumental hydration curve with an untreated control running at baseline throughout, three depth readings, and two separate irritation studies naming this exact product, one reporting a mean skin reaction score of 0.00. What is not a separator, and is recorded here because it would be easy to claim: the birch sap, the glyceryl glucoside and the practice of printing a ppm level all appear on every line sibling checked. Against all that, the brand publishes no usage instruction at all and its headline absorption figure has no measurement behind it.
