Round Lab Birch Juice Moisturizing Cream
Ingredient analysis and how the ad lines read

What is this product?
Reach for this Round Lab birch cream if the goal is a lightweight daily moisturiser with a declared birch sap content of one percent and no fragrance, essential oil or exfoliating acid anywhere in its 38 entries, and skip it if you want a functional cosmetic, because the statutory field records none. The emollients are branched alkanes and a jojoba ester rather than butters or waxes, and two hyaluronic acid forms at 14 and 15, plus panthenol and glyceryl glucoside, do the humectant work. One thing to know: the clinical testing language attached to this product comes from a 2020 trade press article rather than any brand or label surface, and the ingredient list on file here was harvested in 2026.
What makes it different?
Birch sap is declared at 10,000ppm in eighth position, which puts a printed content figure on the ingredient the product is named for. The emollient system is built from isononyl isononanoate, isododecane and polydecene rather than fatty acid esters or plant butters, which is why the fungal acne screen returns only one match and the comedogenic screen returns none. Eleven botanical extracts sit at position 13 and at 16 through 25, a long botanical block for a product whose statutory notice claims no functional cosmetic status. The block is not a single unbroken run: 소듐하이알루로네이트 at 14 and 하이알루로닉애씨드 at 15 sit inside it.
