The listing cannot agree with itself. In one paragraph the mask is formulated with fifty percent Extreme Biome, made up of ten fermented ingredients; a few lines later it is infused with seventy-seven point two percent of the same complex. The ingredient list settles the matter in the only way that counts: bifida ferment lysate is first, ahead of water, and the other ten ferments, bifida filtrate, Bacillus, a Leuconostoc radish ferment, two Lactococcus, three Lactobacillus and two fruit ferments, sit in a tight group near the end, behind the root extracts, the gelling agents and the bergamot oil. A ferment lysate is mostly water, so a high bifida content is plausible and the fifty could even be true of it; the complex as a whole is a small addition, and the seventy-seven is a copywriting slip. Either way the mask is better read from its list than from its listing, and the list is decent. It is worth being fair about how common the slip is: percentage claims for ferment complexes are quoted from the raw material's own dilution as often as from the finished product, and brands rarely say which, so the reader is left to do the arithmetic from the list, which is what the list is for.
Bifida ferment lysate first is a genuine placement for the Night Repair line's signature ingredient, and its evidence, small controlled studies on barrier recovery and reduced sensitivity, is more than most sheet-mask heroes can show. Water, butylene glycol and glycerin follow, then chicory and dandelion root extracts at fifth and sixth, inulin-rich prebiotic humectants placed unusually high, and niacinamide at seventh, which is the ingredient with the clearest record and the source of whatever tone and comfort benefit accrues over weeks. A preservative, propanediol, hydrolyzed jojoba esters, gelling agents, allantoin, panthenol, adenosine, arginine and licorice root make up a solid soothing middle; then hydrolyzed collagen, the bergamot oil, a cocoa extract, a copolymer, five vegetable extracts, a second copolymer, the ferment complex, dextrin, and limonene and linalool declared last. No alcohol, no oil, no silicone, and it is vegan-certified.
On the skin it does what a good ferment sheet does. The cellulose fits closely and holds enough essence for twenty minutes without dripping, the feel is cool and cushioned, and the face on removal is plump, soft and calm with a light tack that a night cream smooths; dry and normal skin feel the difference into the next morning. The cotton dries a little faster than the hydrogel, so twenty minutes is the sensible limit, and a chilled pouch helps on a warm night. Reviewers describe it as the comfortable, dependable one, buy it in the six-pack for a fortnight of evenings, and pair it with the purple ampoule that shares the pouch, which is a sensible sequence. Against the brand's own First Essence pads, which carry a yeast ferment and no niacinamide, this sheet is the more active of the two cheap formats, and against the Vita C Plus sheet it is the calmer. The firming and wrinkle language on the listing describes that plumped morning face, and the brand's clinical proof for elasticity and texture is unpublished; the mask hydrates and, through the niacinamide, evens tone modestly over a month, and that is the honest scope.
The bergamot is the thing to weigh, and it separates this mask from its sibling. Citrus aurantium bergamia fruit oil sits mid-list with limonene and linalool declared, which is a modest but real fragrance load under twenty minutes of occlusion, and bergamot carries furocoumarins with a photosensitising reputation unless the oil has had them removed, which the label does not say; on a mask used at night that risk is small, and on reactive, rosacea-prone or eczema-prone skin the sensitisation risk is not. That combination, a scented essence in a repair line, is a recurring K-beauty habit and not a Missha peculiarity; it is worth naming only because the same brand makes the unscented alternative and sells it for the same nine dollars. The line's First Hydrogel Mask, sold in the same six-pack at the same price, carries no fragrance at all, and for anyone whose skin has ever objected to a scent it is the better nine dollars. A useful test is the corner of the sheet on the jaw for five minutes; a face that stays quiet can have the whole mask, and one that pinks up should have the hydrogel instead.
At a dollar fifty a sheet the mask is inexpensive for one with a bifida lysate first and a real niacinamide placement, and a six-pack is two or three weeks of evenings. A sheet at this price with the ferment first and the niacinamide seventh is doing more than its pouch needs it to, and less than its listing says. So the recommendation is warm for the right skin: dry, normal and combination faces that want a plumping, calming, faintly scented ferment sheet for winter evenings, after the Night Repair ampoule or on its own, will find this a reliable, well-priced one. Sensitive skin should choose the hydrogel, and everyone should read the fifty and the seventy-seven as the same enthusiasm counted twice.
