Soothing
Chamomilla Recutita (Matricaria) Flower/Leaf Extract

Chamomilla Recutita (Matricaria) Flower/Leaf Extract is derived from both the flowers and leaves of German chamomile, yielding a broader phytochemical profile than flower-only extracts. Bioactives include alpha-bisabolol (wound-healing, anti-inflammatory), chamazulene (anti-inflammatory, blue pigment), apigenin and luteolin (flavonoid antioxidants), and phenolic acids from the leaf fraction. Distinct INCI from the flower-only extract; used in soothing and sensitive-skin formulations.

anti-inflammatorysoothingantioxidantskin-conditioning
Chamomile flower and leaf extract is richer in flavonoids (apigenin, luteolin) and phenolic acids than flower extract alone — the additional leaf fraction contributes further anti-inflammatory activityAlpha-bisabolol from the flower fraction provides proven wound-healing, anti-irritant, and skin-calming properties; leaf polyphenols add antioxidant depthWidely documented as one of the most effective botanical anti-inflammatory actives in cosmetics; suitable for reactive, sensitized, and post-procedure skin
Asteraceae family — contact allergy to chamomile (sesquiterpene lactone sensitivity) is rare but documented; patch test recommended for confirmed ragweed-sensitive individuals

Chitosan

Chitosan is a linear polysaccharide derived by partial deacetylation of chitin (found in crustacean shells, insect exoskeletons, and fungal cell walls). The degree of deacetylation determines its cationic charge density — cosmetic-grade chitosan is 75–90% deacetylated. Its cationic nature gives it substantive affinity for skin, excellent film-forming properties, and antimicrobial activity. Used in Korean skincare as a barrier-supportive, skin-conditioning, and gentle anti-microbial active.

film-formingbarrier-repairantimicrobialskin-conditioning
Chitosan is a cationic polysaccharide derived from chitin (crustacean shells) that adsorbs tightly to the negatively charged skin surface, forming a breathable, moisture-retaining film with substantive skin conditioningThe cationic character of chitosan gives it inherent antimicrobial activity against gram-positive bacteria and fungi — relevant for acne-prone and oily skin formulationsLow-molecular-weight chitosan fractions can penetrate into the stratum corneum, reinforcing the lipid barrier and contributing to trans-epidermal water loss reduction
Derived from crustacean shells — not vegan or shellfish-allergy safe; shellfish-allergic individuals should exercise caution, though documented topical reactions are rareHighly cationic — incompatible with anionic polymers (e.g., carbomer, hyaluronic acid at low ionic strength) in formulations; can cause turbidity or precipitation if mixed improperly

Cholesteryl Succinate

The succinate half-ester of cholesterol. Cholesterol is a critical structural component of the skin's lamellar lipid bilayers, maintaining fluidity and barrier integrity.
