The science
The cream's evidence lies in its panthenol, its lipids and its humectants. Dexpanthenol, the provitamin of pantothenic acid, has a substantial clinical literature at concentrations of one to five percent for increasing stratum corneum hydration, reducing transepidermal water loss, calming irritant dermatitis and accelerating barrier recovery after damage; at a declared three percent and seventh position it is dosed and placed as the primary active, and it explains the rapid relief of tightness and the settling of retinoid flaking users report. Seventeen free amino acids with sodium PCA and trehalose reproduce the natural moisturising factor, the water-binding mixture the stratum corneum generates from filaggrin, and topical NMF components measurably raise skin hydration. Ceramide NP, cholesterol and linoleic acid with phytosphingosine and hydrogenated lecithin supply the barrier-lipid classes in a physiological combination, though their tail position indicates a modest dose; squalane, meadowfoam, macadamia and safflower oils add emollience.
Guaiazulene at 300 ppm is a sesquiterpene azulene with laboratory data for inhibiting inflammatory mediators and a long history in Japanese and European topical pharmacy products; a 2024 Molecules review of azulene derivatives summarises its dermatological potential and its laboratory photosensitivity, the latter a reason the blue cream is best worn under sunscreen by day. Adenosine is a Korean-registered functional wrinkle ingredient with modest clinical support.
EGF is present at a dose that cannot be credited with the effect. sh-Oligopeptide-1 at 10 ppm is the Korean cosmetic ceiling; recombinant EGF has small clinical studies in post-procedure and wound settings where the barrier is compromised, and a 2026 randomised, double-blinded pilot in the Journal of Cosmetic Dermatology compared synthetic and human-derived topical EGF for facial rejuvenation with modest outcomes over leave-on use, but penetration of a six-kilodalton protein through intact stratum corneum is poor and no study isolates its contribution in a cream of this composition. The vehicle, a water-in-silicone emulsion of cetyl ethylhexanoate, dimethicone and caprylic/capric triglyceride thickened with stearalkonium hectorite, is non-occlusive and low in comedogenic potential; the triglyceride and ester content is the component fungal-acne-prone skin may react to. The formula contains no fragrance, alcohol, parabens or colourants.
