The science
The honest science of this cream is the science of its finish. Sodium polyacrylate is a cross-linked superabsorbent polymer that binds many times its weight in water and, as it dries on skin, leaves a thin, flexible, matte film that scatters light — the mechanism behind the soft-focus blur and the immediate 'smoother' impression. Arachidyl alcohol and arachidyl glucoside are a long-chain (C20) fatty alcohol and its sugar ester, used together as a naturally derived emulsifier system that gives emulsions a distinctively velvety, powdery skin-feel without particulate powder. Beneath that film, squalane — the hydrogenated, oxidation-stable form of squalene, the hydrocarbon that makes up roughly a tenth of human sebum and declines with age — and macadamia seed oil, unusually rich in palmitoleic acid, an omega-7 fatty acid abundant in young sebum and scarce in mature skin, supply a light, sebum-compatible emollient layer, with glycerin at third as the humectant. That combination reliably lowers transepidermal water loss and keeps a surface hydrated and optically smooth for the day, which is what the brand's 20-person panel was describing when it self-rated skin 'smoother by 63 percent' after 56 days.
The firming claim has less behind it. Chlorella vulgaris extract, twenty-fourth, is the range's 'micro-algae oil'; the relevant published work is a 2025 study in Marine Drugs by Masoumifeshani and colleagues, who enzymatically hydrolysed Chlorella vulgaris and Spirulina platensis proteins and found that the small (under 3 kilodalton) peptide fractions showed strong antioxidant activity and inhibited elastase by 84 percent, collagenase by 90 percent and tyrosinase by 66 percent in vitro, identifying several di- and tri-peptides as candidates. That supports a laboratory rationale for the alga as an anti-ageing ingredient; it says nothing about a whole-cell extract at this position in a leave-on cream, and no clinical trial of the cream exists. Acetyl tetrapeptide-5, twenty-fifth, is a synthetic peptide developed for under-eye puffiness on the basis of reduced vascular permeability and angiotensin-converting-enzyme inhibition; its supplier data concern eye bags, and it carries no claim on this product. Marshmallow root, wakame and sunflower oil are soothing and emollient botanicals at trace levels.
The fragrance deserves its own line: parfum at ninth with Citrus aurantium peel oil and nine declared allergen components — limonene, linalool, linalyl acetate, alpha-isomethyl ionone, geraniol, citronellol, terpineol, a synthetic musk and benzyl alcohol — is a meaningful sensitiser load for a daily leave-on, and the citrus oil adds a minor photosensitivity consideration that a morning sunscreen resolves.
