Parts per billion is an unusual unit to see on a moisturizer, and Missha uses it twice for this cream: sodium DNA at 50,000 ppb and NAD+ at 7,500 ppb. Translated, that is 0.005 percent and 0.00075 percent, and the translation is the review. The two molecules in the name, the salmon-DNA repair ingredient that clinics inject and the longevity coenzyme that supplement companies sell, are present at doses that would embarrass either category, and the brand, to its credit, says so in its own numbers. What the jar actually contains at a working level is at fifth in the list, and it is niacinamide.
That makes the cream easier to judge than its marketing. Niacinamide behind the glycols and glycerin is a real dose for barrier lipids, tone and, over months, modest elasticity, and it has a neat irony to it: niacinamide is the vitamin the skin uses to make its own NAD+, so if anything in this jar supports the coenzyme the label sells, it is the ordinary vitamin at fifth rather than the trace coenzyme at thirty-third. Three fermented-grain extracts, rye, soymilk and soybean, sit eighth to tenth, the 1,080-hour superfood story, and at that placement they contribute amino acids and humectant sugars that genuinely soften and hydrate. Cocoa and camellia flower extracts follow, then a full B-complex scattered through the tail with panthenol at twenty-sixth, allantoin and licorice-derived glycyrrhizate to soothe. There is no fragrance, no alcohol, no oil, no silicone.
The texture is the product's real distinction, and it is the reason for the early enthusiasm. Four acrylate polymers build a dense, bouncy jelly that melts into a cool gel under the fingers and sets, over a couple of minutes, into a thin, close-fitting veil that feels faintly tightened and looks dewy; polyglyceryl-10 oleate is the only emollient in the formula. Oily and combination skin get a complete, refreshing, unscented moisturizer that sits under sunscreen without pilling, and the fifty-odd Amazon reviewers who have found it in its first two months average close to five stars and say plump, cool, glowy. The tightened feel is the film, and it resets with every wash; on dry skin the absence of any lipid shows by the second day, and a richer cream or an oil over it is the fix.
The headline actives deserve a fair hearing before they are set aside. Polydeoxyribonucleotide has genuine evidence, from salmon-derived injectables, for wound healing and tissue repair, and it became K-beauty's ingredient of 2025 on the strength of that clinic association; topical sodium DNA in a cream has in vitro data and no controlled clinical support, and at 0.005 percent it is a signature rather than a dose. Missha's twist, calling its version camellia PDRN and listing camellia flower extract at the same ppb as the DNA, is a plant-sourcing story for a category built on fish, and the camellia contributes a little antioxidant activity and the name. NAD+ is a large, charged coenzyme that does not cross the stratum corneum in meaningful amounts, and NMN and ATP beside it are the same idea at the same trace; the concept is borrowed from longevity supplements, where the molecules are swallowed, and no cream has shown it working on skin.
None of that makes the cream dishonest, and the ppb figures are the reason: Missha discloses the doses, which most trend-chasing brands do not, and a buyer who reads them knows exactly what they are getting. What they are getting is a gentle, fragrance-free niacinamide jelly moisturizer with a satisfying veil, a fermented conditioning base and a B-complex, at twenty-eight dollars for 70 millilitres, three months of twice-daily use, which is fair value for that product and would be poor value for the one on the label.
A note on the texture for people who have not met a Korean jelly cream before, because it explains the split in first reactions. The dense gel is meant to be melted rather than rubbed: a dot pressed between warm fingertips liquefies in seconds and spreads as a thin film, while the same dot rubbed straight onto the cheek drags and beads. The veil that sets afterwards is faintly tacky for a few minutes and then dry to the touch, and it is that dry film, not any active, that produces the tightened feel reviewers describe as firming. Understood as a hydrating film rather than a treatment, it is one of the more agreeable gel textures on the market; misunderstood as a cream, it disappoints on the first night.
Missha, founded in 2000, has built two decades of business on affordable versions of whatever K-beauty is talking about, and this line is that model applied to 2026's two loudest molecules; the brand supports it with dermatologist testing and nothing more, and the cream is two months old in the US, so its reviews are first impressions. So read the parts per billion as the useful part of the marketing. This is a good, clean, cooling gel moisturizer for oily and combination skin, with the niacinamide doing the work and a longevity vocabulary doing the selling, and at this price the vocabulary is nearly free.
