Every ingredient SkinAtlas knows about — all 2277 of them. What each one does, what it works well with, and what to watch for.
Enzymatically or chemically hydrolyzed protein from avocado (Persea gratissima), yielding small peptides and amino acids. These fragments have affinity for skin and hair surfaces, forming a moisture-retaining film and providing a soft, smooth feel. Used in moisturizers, serums, and hair treatments.
A modified hyaluronic acid where C12-13 alkyl glyceryl groups are attached via hydrolysis, creating an oil-dispersible form with improved skin penetration.
Enzymatically broken-down collagen peptides that hydrate and condition the skin surface.
A protein hydrolysate from pearl/shell conchiolin used as a moisturizing, film-forming conditioning agent in Japanese formulas.
A hydrolysate of conchiolin, the structural protein from pearl/nacre (Pinctada spp.). Used in luxury Japanese skincare for its moisturising, conditioning, and film-forming properties.
A partial hydrolysate of corn (Zea mays) starch that acts as a film-former and skin-conditioning agent, distinct from the intact starch in its smaller molecular fragments and enhanced skin compatibility.
Hydrolysate of extensin, the major hydroxyproline-rich glycoprotein (HRGP) of plant cell walls, cleaved into low-molecular-weight fragments for improved skin penetration. Most commonly sourced from carrot (Daucus carota). High hydroxyproline and glycosylated amino acid content parallels animal collagen, while abundant polysaccharide side chains confer water-binding and film-forming properties. Used in K-beauty effector serums for its skin-conditioning and moisture-retention activity.
A hydrolyzed extract from the fruit of Gardenia florida (gardenia/cape jasmine) yielding peptides, polysaccharides, and low-molecular-weight fractions used for skin conditioning and light film formation.
Hydrolyzed Ginseng Saponins are produced by enzymatic or acid hydrolysis of the triterpene saponins (ginsenosides) present in Panax ginseng root. The hydrolysis cleaves sugar moieties, yielding smaller aglycone and protopanaxadiol/protopanaxatriol metabolites (including Rh1, Rh2, Rg3, compound K) that have improved skin penetration versus intact high-molecular-weight saponins. Used in premium Korean skincare as a high-potency, bioavailable form of ginseng active.
Hydrolyzed fragments of glycosaminoglycans (such as chondroitin sulfate and dermatan sulfate) that function as humectants and skin-conditioning agents, similar in concept to hydrolyzed hyaluronic acid.
A protein hydrolysate of the astaxanthin-rich red-phase microalgae Haematococcus pluvialis, yielding skin-penetrating peptide fragments alongside the algae's native astaxanthin carotenoid for antioxidant and skin-conditioning effects.
A hydrolyzed form of the waxy esters from jojoba seed oil used as a lightweight emollient and skin-conditioning agent.
A hydrolyzed extract of malted barley (Hordeum vulgare) yielding a mixture of maltodextrins, amino acids, and simple sugars used as a humectant and skin-conditioning agent.
An enzymatic or acid hydrolysate of freshwater or marine pearl (nacre) yielding amino acids, calcium, and trace minerals that brighten, condition, and hydrate skin.
Hydrolyzed Proanthocyanidin is a hydrolyzed form of proanthocyanidin (condensed tannins / oligomeric proanthocyanidins, OPCs), typically sourced from grape seed, maritime pine bark, or bilberry. Hydrolysis reduces polymer chain length, improving bioavailability and skin penetration. Proanthocyanidins are exceptionally potent antioxidants with documented MMP-inhibitory and collagen cross-linking activity, making them effective anti-aging and skin-firming actives beyond simple radical scavenging.
Protein derived from rice bran that has been hydrolyzed for better skin and hair penetration.
The enzymatically or chemically hydrolyzed form of rice (Oryza sativa) extract; yields smaller molecular weight saccharides and peptides for improved skin penetration and humectant activity.
Enzymatic or acid hydrolysate of rice (Oryza sativa) leaf protein. Yields amino acids and small peptides that condition and smooth skin.
Enzymatically hydrolyzed rice protein peptides that hydrate and condition the skin surface while forming a light film.
Enzymatically hydrolyzed sodium hyaluronate with very low molecular weight for deeper skin penetration and enhanced hydration.
Enzymatically hydrolyzed soybean protein peptides used as a humectant and skin conditioner that helps retain moisture and smooth the skin surface.
A hydrolysate of soybean (Glycine soja) used as a skin-conditioning and mildly firming active. Contains isoflavones (genistein, daidzein) and peptides that condition and protect the skin.
A hydrolysate derived from marine sponge (typically Spongia species), used as a skin-conditioning agent that delivers marine-derived peptides and trace minerals.
A broad INCI category covering protein hydrolysates from plant sources (soy, wheat, rice, corn, pea, etc.) broken down into amino acids and peptide chains by acid, alkali, or enzymatic hydrolysis. Amino acids are NMF components that support the skin's natural moisture-retention capacity. Frequently used in formulas where specific protein sources are not disclosed or where a blend is intentional.
