Every ingredient SkinAtlas knows about — all 2402 of them. What each one does, what it works well with, and what to watch for.
An extract from olive (Olea europaea) leaves, rich in oleuropein, hydroxytyrosol, and flavonoids. Provides potent antioxidant, anti-inflammatory, and mild antimicrobial benefits in skincare.
A pentacyclic triterpene naturally found in olive leaves, olive oil, and rosemary. In cosmetics, used for its antioxidant, anti-inflammatory, and mild tyrosinase-inhibiting (brightening) properties. Also studied for its role in supporting the skin's own ceramide synthesis pathway.
A naturally occurring omega-9 monounsaturated fatty acid (C18:1) found in many plant oils, used as an emollient and penetration enhancer that softens skin and replenishes surface lipids.
A polyethoxylated (10 EO units) ether of oleyl alcohol, used as a nonionic emulsifier and solubilizer in cosmetic emulsions and cleansers.
A polyethoxylated (3 EO units) ether of oleyl alcohol with a low HLB value, used as a co-emulsifier in cosmetic formulations to assist water-in-oil stability.
A phosphate ester of oleth-3 (polyethoxylated oleyl alcohol) used as an anionic co-emulsifier and surfactant in cosmetic emulsions, often combined with oleth-3.
A polyethoxylated (5 EO units) ether of oleyl alcohol with intermediate HLB, used as a nonionic emulsifier and co-solubilizer in cosmetic formulations.
An unsaturated C18 fatty alcohol derived from oleic acid. Used as a rich emollient, co-emulsifier, and thickener in creams and lotions; softens and conditions skin.
An ester of oleyl alcohol and erucic acid (C22:1) used as a lightweight, skin-softening emollient that imparts a silky, non-occlusive skin feel.
An ester of oleyl alcohol and oleic acid that functions as a smooth, penetrating emollient. Imparts a silky, non-sticky skin feel and enhances the spreadability of oil-phase ingredients.
A synthetic tripeptide composed of glycine, histidine, and lysine (GHK) that acts as a copper-binding signal peptide, stimulating collagen and glycosaminoglycan synthesis in fibroblasts and supporting skin repair and anti-aging.
A synthetic lysine-serine-threonine oligopeptide that functions as a skin conditioning and signal peptide, activating the skin's endogenous repair mechanisms to support anti-aging activity.
A synthetic tetrapeptide (four amino acids) that acts as a signal peptide in cosmetics, stimulating skin's natural repair processes to improve firmness, elasticity, and reduce visible aging.
A synthetic hexapeptide that mimics the activity of EGF (epidermal growth factor). Stimulates cell proliferation and collagen synthesis, contributing to skin firming and anti-aging benefits. Used in Lululun's Hydra EX mask.
A synthetic oligopeptide that targets tyrosinase — the key enzyme in melanin production — making it a precision brightening active suited for dark spots and uneven tone.
A synthetic oligopeptide used as an active ingredient in blemish and acne-targeted skincare formulations, distinct from other numbered oligopeptides in the KB.
A refined mixture of glycerides derived from olive fruit oil (Olea europaea), used as a natural-positioned emollient and skin-conditioning agent.
The non-glyceride fraction of olive oil (squalene, sterols, tocopherols) that provides antioxidant and barrier-repair benefits with excellent skin compatibility.
An extract derived from olivine, a magnesium-iron silicate mineral, used as a skin-conditioning ingredient valued for trace mineral content.
INCI catch-all name for unspecified plant-derived oils used as emollients and skin conditioners.
Extract from the root of Ononis spinosa (spiny restharrow), a plant used in traditional European herbal medicine. Contains isoflavonoids and other phytochemicals with tyrosinase-inhibiting and antioxidant properties. Used in brightening skincare.
Onsen-Sui (温泉水) is the INCI-listed name for Japanese hot spring (onsen) water used as an ingredient in cosmetics. Onsens are geothermal mineral springs found throughout Japan, and their water carries dissolved minerals that vary by location and geological source. In cosmetics it is used as a mineral-enriched water alternative, replacing or supplementing regular purified water for marketing differentiation and the trace mineral benefits the water's source provides.
An extract from the tuberous roots of Ophiopogon japonicus (lilyturf / Maidong), a classic TCM herb; rich in steroidal saponins and fructo-oligosaccharides that provide humectant, soothing, and skin-conditioning benefits.
An extract from the fruit of Opuntia coccinellifera (nopal/prickly pear cactus), rich in polysaccharides, betalain pigments, and antioxidants; used in cosmetics for its moisturising and soothing properties.
