Summary

Skin Conditioning Anti-inflammatory Soothing Antioxidant Hydrating Decongestant Astringent Antibacterial Melanin Reduction

Science

Mechanism of Action

This extract exerts its effects primarily through N-feruloylserotonin, which potently neutralizes pro-inflammatory chemokines (CCL17, CCL22) and inhibits key enzymes (COX-2, 5-LOX) involved in inflammatory pathways. Its rich flavonoid and polyphenol content provides robust antioxidant protection by inhibiting reactive oxygen species and chelating metallic ions, thereby safeguarding skin from oxidative damage and supporting youthful appearance. Polysaccharides contribute to its soothing action, while its ability to significantly increase stratum corneum hydration enhances skin softness and elasticity. The extract also demonstrates a decongestant effect, particularly beneficial for the delicate eye area by improving microcirculation to reduce puffiness and dark circles, alongside astringent and potential melanin-reducing properties.

Stability

The extract is water-soluble, with optimal stability observed within a pH range of 4.5 to 7.0. Anthocyanins, key color and active components, may be susceptible to structural transformations at lower pH levels, specifically around pH 3.5. Its moisturizing efficacy can be enhanced when co-formulated with glycerin.
