Every ingredient SkinAtlas knows about — all 2402 of them. What each one does, what it works well with, and what to watch for.
A naturally occurring amino acid that functions as a humectant and is a component of the skin's natural moisturizing factor.
An aqueous or hydroalcoholic extract from sesame seeds (Sesamum indicum) rich in lignans and polyphenols, used in cosmetics for antioxidant and skin-conditioning benefits, distinct from the fatty seed oil.
Cold-pressed oil from sesame seeds (Sesamum indicum), a traditional emollient rich in linoleic and oleic fatty acids and natural antioxidants including sesamol and tocopherols.
An extract from germinated sesame (Sesamum indicum) sprouts. Sprouts are richer in antioxidant lignans and flavonoids than mature seeds. Used in luxury skincare for potent antioxidant and conditioning effects.
An extract from the leaves of Setaria italica (foxtail millet / bottle grass), a grass species used in Korean cosmetics under the common trade name 'bottle grass leaf extract' for soothing and antioxidant properties.
A rich plant butter high in fatty acids.
A lighter derivative of shea butter made by esterification with ethanol, providing emollient skin conditioning without the heavy feel of raw shea butter.
Shea butter processed via glycerolysis to produce a more elegant, lighter-feeling emollient than traditional shea; retains the fatty acid and unsaponifiable fraction benefits.
A natural naphthoquinone pigment found in the roots of Lithospermum erythrorhizon and related plants. Has significant antioxidant, anti-inflammatory, and antimicrobial activity. Used as a natural colorant and functional active.
Illipe butter, a firm plant fat pressed from Shorea stenoptera seeds native to Borneo, used as a rich emollient with a high melting point.
A water-soluble organosilicon compound (methylsilanetriol) used in cosmetics to condition skin, form a lightweight film, and support moisture retention with a smooth, silky finish.
A fine silicon dioxide powder used as an absorbent, texture improver, and mild thickener in cosmetics.
A composite of silica and aluminum hydroxide used as a mild abrasive, absorbent, and texturizer in cosmetic formulas. Provides a silky, matte finish in sunscreens and color cosmetics.
Hydrophobic fumed silica treated with dimethylsilyloxyl groups, used to thicken and gel oil-phase formulas and suspend pigments or mineral sunscreen particles in anhydrous systems.
Amorphous silica that has been surface-treated with dimethylsilylate groups, rendering it hydrophobic. The coating gives the particles a dry, non-clumping character and a smooth, powdery skin feel. Used in pressed powders, foundations, sunscreens, and primers to control shine, improve spreadability, and add a matte finish.
A hydrated form of silicon dioxide used as an absorbent, thickener, and soft-focus agent in sunscreens and BB creams.
Hydrophobic fumed silica surface-treated with silyloxyl groups, used as a thickener, anticaking agent, and pigment suspending agent in anhydrous and sunscreen formulas.
The amino acid fraction obtained by hydrolysis of silk fibroin, the structural protein of silk from Bombyx mori silkworm cocoons. Rich in glycine (~46%), serine (~12%), and alanine (~29%). Distinct from 'Hydrolyzed Silk' (which refers to larger peptide fragments), though both are derived from the same source. Absorbs into skin to replenish NMF components and provides a smooth, slightly substantive skin feel.
A silk-derived protein extract that hydrates and imparts a smooth, conditioned feel.
Finely milled powder from Bombyx mori silk proteins. Imparts a silky, smooth feel to skin and cosmetic formulas; used in powders, foundations, and skincare for its texture-enhancing properties.
A silver compound with antimicrobial properties. Used in Kiku-Masamune's sake emulsion as a preservative/antimicrobial booster.
Milk thistle extract rich in protective flavonoids.
Oil cold-pressed from the seeds of milk thistle (Silybum marianum), a linoleic-acid-rich emollient with antioxidant silymarin flavonoids.
An extract derived from smithsonite, a zinc carbonate mineral, providing trace elements used in cosmetics for antioxidant, anti-glycation, and skin-conditioning activity.
