Ingredient library
Every ingredient SkinAtlas knows about — all 2165 of them. What each one does, what it works well with, and what to watch for.
A peptide marketed to relax expression lines.
Pure vitamin C; a potent antioxidant and brightener.
A hybrid molecule formed by esterification of ascorbic acid (vitamin C) with the carboxyl groups of hyaluronic acid via a propyl linker. Combines the antioxidant/brightening properties of ascorbic acid with the humectant properties of hyaluronic acid. The ester bond provides improved stability versus free L-ascorbic acid while still hydrolyzing to release the active forms. Used in multi-functional serums for combined brightening, antioxidant, and hydration benefits.
A multitasker for redness, acne and pigmentation.
A fermented soybean extract using Bacillus species bacteria. Fermentation by Bacillus transforms soy compounds, potentially enhancing isoflavone bioavailability and adding probiotic metabolites. Used in Sana's fermented lotion.
A plant-derived ingredient with retinol-like benefits and less irritation.
A bee-derived active marketed for temporary firming, but a significant allergen for sting-sensitive users.
A cell-free filtrate obtained from Bifidobacterium fermentation, distinct from bifida ferment lysate in that it contains only secreted metabolites and exopolysaccharides without cellular debris, used for barrier reinforcement and soothing.
Broussonetia kazinoki (paper mulberry) root extract is a cornerstone brightening ingredient in Korean beauty. Its distinctive prenylated flavonoids — particularly kazinol F and broussochalcone A — inhibit tyrosinase more potently than kojic acid in several comparative in vitro studies, making it highly effective for addressing melasma, PIH, and uneven skin tone. Widely used in K-beauty brightening serums and essences, often paired with niacinamide for complementary melanin inhibition mechanisms.
The calcium salt form of vitamin B5 (pantothenic acid), which is more stable than panthenol and supports fibroblast activity, skin regeneration, and moisturization.
Plant-cell-culture-derived extracellular vesicles (exosome-like) from Centella asiatica callus, carrying bioactive lipids, proteins, and miRNAs that stimulate skin repair, collagen synthesis, and barrier recovery.
An extract from quinoa seeds (Chenopodium quinoa) rich in amino acids, flavonoids, and vitamins, used in premium skincare for antioxidant, brightening, and skin-conditioning properties.
A non-volatile extract of Ceylon cinnamon (Cinnamomum zeylanicum / C. verum) bark, containing cinnamaldehyde, eugenol, and polyphenols; used for antioxidant and antimicrobial effects but carries meaningful skin sensitization risk from its fragrance-active constituents.
An extract from the fruit of the lime tree (Citrus aurantifolia) containing vitamin C, flavonoids, and citric acid, used for antioxidant and brightening effects; contains furanocoumarins that can increase UV sensitivity.
An extract from horseradish root containing peroxidase enzymes and glucosinolates, used in exfoliating toners (notably Biologique Recherche P50) for mild enzymatic exfoliation and brightening.
A signaling peptide that supports skin repair and firmness.
An extract from the mycelium of Cordyceps militaris, a red-orange entomopathogenic fungus; distinct from the rare Cordyceps sinensis, it contains cordycepin, adenosine, and beta-glucans with antioxidant, anti-inflammatory, and skin-revitalizing properties.
Extract from the mycelium of Ophiocordyceps sinensis (syn. Cordyceps sinensis), a high-altitude fungus. Key bioactives include cordycepin (3'-deoxyadenosine), adenosine, and beta-glucan polysaccharides. Cordycepin modulates cellular energy pathways via NAD+ biosynthesis and sirtuin activation, while polysaccharides contribute humectant and barrier-supporting properties. EU CosIng registers five cosmetic functions: antioxidant, humectant, and skin conditioning.
An extract from the mycelium of Cordyceps sinensis (caterpillar fungus / Dong Chong Xia Cao), a rare Himalayan TCM fungus; contains polysaccharides, cordycepic acid, and nucleosides with antioxidant and adaptogenic skin-revitalizing properties.
A naturally occurring nitrogenous compound that serves as a cellular energy buffer; applied topically it may support ATP regeneration in skin cells, with anti-aging and photoprotective properties suggested by early clinical studies.
The synthetic, stable form of vitamin B12, used in cosmetics for its antioxidant and skin-conditioning properties; studies suggest topical B12 can reduce eczema symptoms and support skin barrier recovery.
The sodium salt of deoxyribonucleic acid (DNA), typically sourced from salmon milt (sperm). Highly hydrophilic — attracts and retains moisture. Also promotes skin cell repair mechanisms. Used in Lululun's Hydra PD mask.
Methylsulfonylmethane (MSM), a naturally occurring organic sulfur compound used topically to support collagen production, soothe inflammation, and improve skin hydration and texture.
The dipalmitoyl ester of hydroxyproline (the key amino acid in collagen) designed for oil-phase delivery; stimulates collagen synthesis and protects skin structural proteins to firm and smooth aging skin.
