Every ingredient SkinAtlas knows about — all 2402 of them. What each one does, what it works well with, and what to watch for.
Polysilicone-11 is a high-molecular-weight silicone polymer (a polysiloxane copolymer with functional groups) used as a film-former and sensory modifier in serums and lightweight skincare formulations. It provides a smooth, non-greasy skin feel and can contribute optical softening effects. Distinct from lower-molecular-weight dimethicone and cyclopentasiloxane in its film-forming and substantivity properties.
A polymeric UV filter where benzalmalonate UVB-absorbing chromophores are covalently attached to a polydimethylsiloxane backbone. High molecular weight prevents significant skin penetration. Approved in EU and Japan. Used in Anessa Perfect UV.
A crosslinked silicone elastomer (polysiloxane) used as a film-former and sensory modifier in cosmetics. Provides a weightless, non-greasy finish. Widely used in Japanese sunscreens (including Biore UV products) to achieve their distinctive light, watery texture.
A mild, nonionic polyoxyethylene sorbitan ester used to solubilize oils and stabilize water-based formulas.
A mild nonionic polyoxyethylene sorbitan ester (Tween 60) used to emulsify and solubilize oils in water-based cosmetic formulas.
A mild, nonionic polyoxyethylene sorbitan monooleate ester (Tween 80) widely used to emulsify and solubilize oils in water-based cosmetic and pharmaceutical formulas.
Synthetic polymer microspheres added to sunscreen and colour cosmetics for optical blurring. Used in Rohto Skin Aqua Super Moisture Gel for its photo-finish soft-focus effect.
A thin, flexible synthetic polymer film used as the outer backing layer of acne patches and wound dressings, providing a protective, occlusive barrier over the adhesive layer.
A polyurethane-based polymer used as a film-forming and viscosity-controlling agent in cosmetic formulations, creating flexible protective barriers with excellent biocompatibility.
A polyurethane-based film-forming polymer used as the flexible carrier matrix in hydrocolloid acne patches and dressings.
A water-soluble synthetic polymer used as a film-former and thickener in sunscreens and peel-off masks, providing a smooth, even texture.
An extract from the unripe fruit of Poncirus trifoliata (trifoliate orange), a traditional Korean medicinal plant used in cosmetics for its soothing, anti-inflammatory, and antioxidant flavonoid content.
A furanoflavonoid diketone isolated from karanja (Millettia pinnata) seed oil with documented antioxidant and anti-inflammatory activity.
Extract from Poria cocos (fu ling / wolfiporia extensa), a medicinal fungus widely used in traditional Korean and Chinese medicine; provides beta-glucans for antioxidant and calming effects in prestige hanbang skincare.
A polysaccharide-rich fu-ling mushroom extract that calms and hydrates skin.
An extract of red microalgae (Porphyridium cruentum) rich in sulfated polysaccharides, used for its water-binding and antioxidant properties.
An extract of purslane traditionally used to calm and soothe reactive skin.
A naturally occurring aluminum potassium sulfate mineral salt used as an astringent, mild antibacterial, and deodorant active in beauty waters, deodorants, and after-shaves.
A stabilized vitamin C + vitamin E hybrid derivative that delivers paired antioxidant and brightening benefits with good formula stability.
The potassium salt of aspartic acid, used in cosmetics as a skin-conditioning agent that provides both a mineral component (potassium) and an amino acid (aspartate) associated with cellular energy metabolism.
A water-soluble azelaic acid derivative. Milder and more soluble than azelaic acid, it targets uneven tone, redness and excess sebum.
The potassium salt of benzoic acid used as a preservative in cosmetics, particularly effective in low-pH formulations against bacteria, yeasts, and molds.
The potassium salt of cetyl phosphate, a mild anionic emulsifier widely used in premium skin-care creams and lotions to create stable oil-in-water emulsions.
An inorganic potassium salt used in cosmetics as an ionic viscosity modifier and buffering agent, also providing mineral supplementation in spa-type and mineral-infusion formulations.
