For twenty years the most prestigious idea in Asian skincare has been a yeast ferment: a clear liquid produced by a Saccharomyces strain, sold at a price that implied the yeast had a doctorate. Chinese brands watched that market from the outside until Chando, in 2021, announced its own strain, isolated from an extreme cold-adapted environment, patented, and named HiMurchaSin, and built an entire line around it that the domestic market promptly nicknamed the little purple bottle. This emulsion is the milky step of that line, and it is worth reviewing because it puts the ferment where it can be judged: second on the list, ahead of every glycol, as the water phase of the product rather than a garnish on it.
That is the first thing the INCI tells you, and it is more meaningful than it sounds. Ferment filtrates are mostly water and their position overstates their active content, but a filtrate in second place means whatever the yeast produced, amino acids, small peptides, a little natural ergothioneine and the assorted metabolites that ferment marketing calls 'nutrients', is present at the ferment's own strength, not diluted into a splash. Chando's claims for HiMurchaSin, collagen stimulation, an anti-fatigue effect, the fading of what it calls the six fatigue lines, come from its own laboratories and have not been published where a sceptic can read them. What can be said is that the ferment is not decorative, and that yeast ferments as a class have a plausible, if under-studied, record for hydration and barrier support.
The second thing the list tells you is that Chando did not trust the yeast to work alone, which is the mark of a formulator rather than a storyteller. Niacinamide is sixth, directly after the emollient ester, which is a real dose for an emulsion and the most independently proven active in the bottle. Tranexamic acid sits lower, just after the fragrance ester, and together the two attack sallow, uneven tone at different points in the pigment pathway, which is a sensible pairing for skin that reads as tired rather than spotted. Ergothioneine, the mushroom-and-yeast antioxidant that skin cells import through a dedicated transporter, appears in the trace tail at what the brand says is 99 percent purity, and the list closes with a cyclic decapeptide and acetyl hexapeptide-8, the usual peptide handshake at the usual peptide doses. None of these is a lift. Together they are a credible tone-and-freshness formula that a Korean or Japanese brand would price considerably higher.
The texture is the part that wins converts. This is a thin lavender-white milk emulsified with sorbitan olivate and hydrogenated lecithin around jojoba oil, a wax ester close to skin's own sebum, with a phenyl trimethicone for slip and a couple of light esters for glide. Two pumps cover the face and neck, it disappears in under a minute, and the finish is hydrated satin rather than film. On combination skin it is the whole moisturizer; on dry skin in winter it is the layer under a cream. Chando suggests applying it thickly as a ten-minute mask on tired days, which is a pleasant way to use more product and does add a temporary plumpness. The pump bottle is elegant on a shelf and hopeless in a suitcase.
What holds it back is familiar. The formula is fragranced, with parfum and methyldihydrojasmonate, a jasmine-like material, in the lower half, and the brand's 'free from three additives, suitable for sensitive skin' line means free of certain preservatives and colourants rather than free of scent. The fragrance is light and gone in minutes, and most skin will not mind; rosacea-prone or sensitised skin should patch-test before trusting the label. The esters that make it glide, isononyl isononanoate, neopentyl glycol diethylhexanoate and triethylhexanoin, are the kind fungal-acne-prone skin tends to blame, and the jojoba will not help there either.
Chando itself is not a brand that needs benefit of the doubt on manufacturing. Founded in Shanghai in 2001, it is one of the biggest domestic skincare companies in China, runs a group R&D centre of some twenty laboratories and opened a Himalaya research institute in 2017, and the discipline in this base, the preservation system, the emulsifier choice, shows that scale. Where it does need the doubt is evidence: every efficacy claim on the bottle traces to internal work, and the English-language user record since the 2025 YesStyle listing is a couple of dozen comments. The chemistry is legible; the results are the brand's word.
Price is the reason to hesitate, and only for Western buyers. On YesStyle the 110 g bottle lists around CA$52 before shipping, with no US retailer to anchor a dollar price; in China the line sits in the brand's upper-mid tier, and marketplace resellers quote whatever they can. At fifty-odd dollars for a hundred and ten grams of a niacinamide-and-tranexamic emulsion built on a real ferment, the value is fair and the per-use cost is low, because the milk goes a long way. For anyone who has wondered what a Chinese yeast ferment feels like next to the famous ones, this is the affordable answer, and the answer is: like a very good emulsion with a story attached, which is what the famous ones feel like too.
