Artemisia Argyi Leaf Extract

Artemisia argyi (Chinese mugwort, Ai Ye / 艾叶) leaf extract is derived from a perennial herb widely used in Traditional Chinese Medicine and moxibustion therapy. It is distinct from Artemisia vulgaris (European mugwort) and Artemisia capillaris (Asian capillary wormwood). The extract's bioactives — eucalyptol, camphor, flavonoids (artemetin, eupatilin), and caffeic acid derivatives — collectively deliver anti-inflammatory, antimicrobial, and antioxidant benefits suited to soothing and skin-calming formulas.

Active
Ascorbyl Propyl Hyaluronate

A hybrid molecule formed by esterification of ascorbic acid (vitamin C) with the carboxyl groups of hyaluronic acid via a propyl linker. Combines the antioxidant/brightening properties of ascorbic acid with the humectant properties of hyaluronic acid. The ester bond provides improved stability versus free L-ascorbic acid while still hydrolyzing to release the active forms. Used in multi-functional serums for combined brightening, antioxidant, and hydration benefits.
