Green Tea Water Cream

A versatile vitamin B3 derivative with multiple benefits.

A gold-standard humectant that draws water into the skin.

Pro-vitamin B5 that soothes and hydrates.

A naturally occurring amino acid that acts as a humectant and supports the skin's own moisture-retention system.

A licorice-root-derived salt that calms inflammation and soothes irritated, reactive skin.

A gentle soothing and skin-conditioning agent.

Natto gum is polyglutamic acid (PGA) — a biopolymer produced by Bacillus subtilis during the fermentation of soybeans (natto). It has extraordinary water-holding capacity, exceeding even hyaluronic acid. Used in Matsuyama's Hadauru ceramide line for superior moisturization.

The salt form of hyaluronic acid; penetrates more readily.

A nucleoside used at low concentrations to help smooth the look of fine lines; a common K-beauty anti-aging active.

A polyphenol-rich antioxidant that also calms skin.

Vitamin E; a lipid-soluble antioxidant that also conditions skin.

sh-Decapeptide-7 is a recombinant human decapeptide produced synthetically to be identical to an endogenous neuropeptide sequence. It belongs to the enkephalin/neuropeptide family and functions as a skin-protecting and anti-irritant active, modulating the response to cutaneous stressors. Used as part of multi-factor growth factor complexes in K-beauty anti-aging formulas (cream, serum), typically alongside other sh- peptides such as sh-Octapeptide-4 and sh-Polypeptide-7.

sh-Octapeptide-4 (Neuropeptide-1; trade name SpecPed Sh-O4P by Spec-Chem Industry Inc) is a recombinant human octapeptide produced synthetically to be identical to Leu-Enkephalin, an endogenous opioid neuropeptide. In cosmetics, it functions primarily as an anti-seborrheic and skin-protecting active — modulating sebum output and reducing cutaneous oxidative stress. Its barrier-conditioning and chelating properties complement its neuropeptide-driven activity. Used in multi-peptide anti-aging and skin-balancing formulas.

sh-Oligopeptide-9 is a recombinant human oligopeptide produced synthetically to be identical to an endogenous protein sequence. EU CosIng and INCI Beauty databases list its cosmetic functions as humectant, skin conditioning, and skin protecting. It appears in multi-factor growth factor cream formulas alongside sh-Decapeptide-7, sh-Octapeptide-4, sh-Pentapeptide-19, and sh-Polypeptide-7 as part of an integrated skin rejuvenation complex.

sh-Pentapeptide-19 is a recombinant human pentapeptide identical to a 5-amino-acid endogenous enkephalin-related sequence. It functions as a skin-conditioning and anti-aging active, used in multi-peptide growth factor complexes for improved skin elasticity, firmness, and overall skin quality. It may be paired with Tripeptide-7 in formulations as a complementary complex. Used in K-beauty premium moisturizers alongside other sh- growth factor peptides.

A signaling peptide that supports skin repair and firmness.

sh-Polypeptide-7 is a recombinant human polypeptide produced by fermentation in E. coli, consisting of a single-chain synthetic fusion peptide identical to an endogenous human growth factor sequence. EU CosIng lists its functions as skin protecting and anti-seborrheic. Based on patent literature and the growth factor complex context in which it appears (alongside sh-Oligopeptide-1 in other formulas), it is likely related to the KGF/FGF-7 (keratinocyte growth factor) family. Used in multi-factor K-beauty anti-aging cream formulas.
