Ingredient library
Every ingredient SkinAtlas knows about — all 2255 of them. What each one does, what it works well with, and what to watch for.
An aqueous extract from the root of Cynanchum atratum (Bai Wei), a TCM plant, clinically shown to improve skin barrier function and reduce itch in subjects with barrier dysfunction, with anti-inflammatory and antioxidant activity.
An extract from artichoke (Cynara scolymus) leaves rich in polyphenolic acids and flavonoids, used for antioxidant protection, brightening, and soothing benefits.
An aqueous extract from the North American yellow lady's slipper orchid (Cypripedium pubescens) used in soothing and anti-stress skincare formulations.
A sulfur-containing amino acid that acts as a humectant and antioxidant in cosmetics, contributing to skin hydration and supporting the skin's own defense mechanisms.
The oxidized dimer of cysteine formed by a disulfide bond between two cysteine molecules; used in cosmetics as a conditioning amino acid with roles in keratin integrity and as a precursor to antioxidant glutathione — distinct from cysteine (the monomer free thiol form).
Extract from Cystoseira tamariscifolia, a brown marine algae (rainbow wrack). Contains polyphenolic phlorotannins and sulfated polysaccharides with antioxidant, anti-inflammatory, and skin-conditioning properties.
The delta isomer of natural vitamin E (d-form). Has the lowest vitamin E activity of the four tocopherol isomers but strong antioxidant potency; used in formulas for its stabilizing and skin-conditioning effects.
A formaldehyde-releasing preservative that slowly releases trace formaldehyde to provide broad-spectrum antimicrobial protection in cosmetic formulations.
DNA (deoxyribonucleic acid) in cosmetics refers to isolated and purified DNA — often from salmon milt (salmon sperm) as a sustainable byproduct — used as a humectant and skin-conditioning active. The phosphate backbone of DNA binds water strongly, delivering surface hydration and a moisturizing film. Low-molecular-weight depolymerized fractions may have skin conditioning benefits. Distinct from medical-grade PDRN (polydeoxyribonucleotide), which is a specific fraction with tissue-regeneration activity administered by injection.
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.
Extract from carrot root, rich in carotenoids (beta-carotene), vitamins, and antioxidants. Used for its antioxidant properties and contribution to a healthy skin tone.
An extract from carrot (Daucus carota sativa) root rich in beta-carotene and other carotenoids, used in cosmetics for antioxidant and skin-brightening benefits.
The pressed juice of black (anthocyanin-rich) carrot varieties, used as a natural antioxidant colorant and skin-conditioning ingredient distinct from orange carrot root extract.
A seed oil cold-pressed or steam-extracted from carrot seeds, rich in carotenoids and tocopherols, used as an antioxidant-rich emollient in facial oils and serums.
A linear volatile silicone (L4) used as a lightweight carrier and emollient in serums and primers. Evaporates after application, leaving a smooth skin feel.
An ester created from decyl alcohol and coconut-derived fatty acids (Cocos nucifera) that functions as an emollient with a smooth, silky feel.
A gentle non-ionic alkyl glucoside surfactant derived from glucose and fatty alcohols, widely used in mild cleansers and baby products for its low irritation profile.
An ester of decyl alcohol and oleic acid that functions as an emollient, skin conditioner, and solvent in cosmetic formulations.
A 10-carbon 1,2-diol with broad-spectrum antimicrobial activity, often combined with caprylyl glycol or phenoxyethanol in paraben-free preservation. Provides mild skin-conditioning benefits.
A naturally derived cyclic lactone preservative approved for both conventional and Ecocert/COSMOS-certified natural cosmetics, effective against bacteria and fungi.
A modified form of xanthan gum where the side-chain carboxyl groups have been partially dehydrated, altering its electrolyte tolerance and rheological behavior. While standard xanthan gum can thin out in high-ionic-strength formulations (with electrolytes like salts, acids, or certain actives), dehydroxanthan gum maintains viscosity across a broader range of ionic conditions. Provides a cleaner, more elegant texture than conventional gums in lightweight K-beauty formulas.
Extract from Delesseria sanguinea, a red marine algae. Rich in sulfated polysaccharides, phycoerythrin pigments, and other bioactives with soothing, antioxidant, and film-forming properties.
A branched polysaccharide of α-D-glucose units primarily linked α(1→6), produced by fermentation of Leuconostoc mesenteroides. Distinct from dextrin (a partially hydrolyzed starch). In cosmetics, dextran forms a hydrophilic film on skin surfaces, providing temporary plumping, hydration retention, and a silky skin feel. Used in premium serums and masks for its biopolymer moisturizing and film-forming properties.
A succinic acid ester of dextran (a bacterial polysaccharide). Functions as a humectant and film-former in skincare. Found in Elixir's brightening emulsion.
