Amomum Xanthioides Seed Extract

Amomum xanthioides (Sha Ren, lesser cardamom) seed extract is derived from an aromatic spice plant widely used in Traditional Chinese Medicine and Korean herbal formulations. Its essential oil fraction (camphor, borneol, bornyl acetate, linalool) gives it a distinctive warm, spicy-camphoraceous scent and antimicrobial properties. In cosmetics its primary role is fragrance; linalool must be declared per EU Cosmetics Regulation and camphor has defined concentration limits.

Provides a warm, spicy-camphoraceous aromatic character to formulations via its dominant volatile constituents (camphor, borneol, bornyl acetate, linalool)Antimicrobial properties of the volatile terpenoid fraction (borneol, camphor) may contribute mild preservative-boosting effectsMinor skin-conditioning benefit at typical cosmetic use concentrations; aromatic function dominates
Linalool is a listed EU fragrance allergen (must be declared above 0.001% in leave-on / 0.01% in rinse-off per EU Cosmetics Regulation)Camphor has explicit EU concentration restrictions (limit 1.5% in non-medicated face/body products) and is a known irritant at higher concentrations

Angelica Acutiloba Root Water

Angelica Acutiloba Root Water is a hydrosol or aqueous extract from the roots of Angelica acutiloba (Toki, Japanese angelica), a plant in the Apiaceae family central to traditional Japanese and Korean herbal medicine. The root is a classic ingredient in Oriental medicine for promoting skin clarity and improving complexion. Its aqueous fraction delivers ferulic acid, chlorogenic acid, ligustilide, and related bioactives. Distinct from Angelica dahurica (Bai Zhi, with furanocoumarin phototoxicity concerns) — Angelica acutiloba has a different phytochemical profile.

Contains furanocoumarins (bergapten, xanthotoxin, imperatorin) — phototoxic at high concentrations; risk is concentration-dependentMay cause photosensitivity with sun exposure; avoid leaving high-concentration formulas on skin before UV exposure
Active
Angelica Dahurica Root Extract

Angelica Dahurica Root Extract (Bai Zhi / 白芷) is derived from a root in the Apiaceae family deeply embedded in traditional Chinese and Korean medicine for brightening, anti-inflammatory, and antimicrobial activity. Its bioactives include coumarins, furanocoumarins, volatile oils, and polyacetylenes — the furanocoumarins (psoralen, bergapten) are photosensitizing agents that render standard extracts unsuitable for leave-on daytime use without confirmed furanocoumarin removal per SCCS limits.

skin-brighteninganti-inflammatoryskin-conditioningantimicrobial
Coumarins (oxypeucedanin, isoimperatorin, phellopterin) and furanocoumarins contribute to skin-brightening effects by modulating melanin synthesis pathways — a traditional East Asian brightening ingredient with documented depigmenting activityAnti-inflammatory polyacetylenes and volatile oil components help calm irritation and reduce redness, complementing its brightening use in uneven skin tone formulasAntimicrobial activity from its alkaloid and coumarin fraction supports use in formulas targeting congested or acne-prone skin
Contains furanocoumarins (psoralen, bergapten, imperatorin) — these are phototoxic compounds. Topical application followed by UV exposure can cause phototoxic reactions (erythema, hyperpigmentation, blistering). SCCS guidance: bergapten ≤1 ppm in leave-on productsPM-only use is strongly advisable for standard extracts not certified furanocoumarin-free; leave-on daytime use requires confirmed furanocoumarin removal to safe levels
