The tube says Retinol 500 IU, and the unit is the review. International units are how vitamin supplements measure retinol, and one IU is three tenths of a microgram; five hundred of them are about 0.15 milligrams, which spread through a gram of cream is roughly 0.015 percent, and through the whole sixty-millilitre tube would be less than a hundredth of that. Retinol products that publish percentages use 0.1 to 1 percent, and the studies that show retinol smoothing lines and evening tone use those doses over months. Missha chose a unit that makes a trace sound like a shot, and the ingredient list, where retinol sits thirty-ninth behind six essential oils and ten ferments, confirms which it is. The unit is also new to the line's own vocabulary: the companion Retinol Intensive Ampoule launched the same month uses the same IU figure, so the choice is a house style rather than a slip, and it is one worth being suspicious of wherever it appears.
What the tube contains in quantity is a rich night cream, and read as one it is decent. Water, a preservative, then bifida ferment lysate at third, the Night Repair line's signature lysate with small but genuine barrier data, and then shea butter, palmitic and stearic acids, glycerin and a triglyceride, the balm-like base that gives the cream its thick, cushioned feel. A polyolefin, a silicone and emulsifiers follow, then niacinamide at thirteenth, betaine and panthenol, gelling and stabilising agents, and, from twenty-third, the oils: bergamot, geranium, orange, lavender, Roman chamomile and sandalwood. The ten-ferment Extreme Biome complex comes next, then the retinol in its polymer shot, vitamin E, thickeners, rice extract, adenosine, a phospholipid, palm oil, a Bacillus ferment, five vegetable extracts, a yeast ferment, and a tail of ceramide NP, elastin, collagen, alcohol, a hyaluronate, cholesterol and olivates, with limonene, citronellol, geraniol and linalool declared last. The brand's US listing prints several of these entries twice, which is careless rather than sinister, and the list above is the cleaned version.
On dry skin the cream does what its base promises. It spreads like a softened balm, settles to a cushioned, faintly glossy finish, and leaves skin soft and comfortable by morning without a hint of the dryness a retinoid usually brings, because there is no meaningful retinoid to bring it; reviewers who wanted a rich winter night cream are happy, and reviewers who wanted retinol results describe finishing the tube and seeing nothing they could attribute to it. Reviewers who like the cream describe it in the vocabulary of moisturisers, soft, nourished, comfortable, and almost never in the vocabulary of retinoids, which is the most accurate consumer testing the product has had. The niacinamide at thirteenth is the ingredient most likely to deliver a modest evening of tone over months, and the bifida lysate and shea are the comfort; the retinol at this level is, at most, a gentle introduction that a nervous beginner could tolerate, which the brand's dermatologically-tested-for-sensitive-skin line seems designed to say. A dry face in a cold month, layered under it after the ampoule, gets exactly the cushioned, glossy morning that a good shea cream delivers, and there are worse ways to spend twenty-five dollars.
The oils undo that line. Six essential oils in the top thirty of a night cream is a heavy load, and on a product that already asks for daily sunscreen because of its retinol, bergamot and orange peel add a photosensitivity consideration the brand does not address; the four declared allergens are the usual suspects in fragrance patch-test series, and alcohol appears in the tail. Sensitive, rosacea-prone and eczema-prone skin, the very people a 0.015 percent retinol might suit as a starter, are the people most likely to react to the rest of the tube, and a first retinoid that stings from its scent rather than its active is a discouraging place to begin. It is the same pattern as the line's essence cream, a comfortable base carrying a heavy scent, and the same recommendation follows.
On cost the cream is fair for what it is and poor for what it says. Twenty-five dollars for sixty millilitres of a shea-and-ferment night cream with niacinamide is reasonable, and a tube lasts two to three months; twenty-five dollars for a retinol treatment at a fortieth of a working dose is not, and the brand's own line offers the ferment without the retinol pretence in the Night Repair ampoule and cream.
So the recommendation separates the two products in the tube. Dry, normal and resilient skin that wants a rich, comfortable, strongly scented night cream with a real bifida base and niacinamide, and does not mind a trace of retinol along for the ride, will like it and should ignore the shot. Anyone wanting a retinol result should buy a product with a percentage on it; anyone with sensitive or oily skin should skip the tube for the oils and the shea; and nobody should use it while pregnant, however small the dose. The arithmetic is the whole review, and the tube invites it by printing the number.
