Valuable / ANTIMICROBIAL, ANTIOXIDANT, HAIR CONDITIONING, HUMECTANT

A turnip-derived callus extract that functions as a multi-target active ingredient for addressing hyperpigmentation and skin aging. This botanical extract combines melanogenesis inhibition with basement membrane protein synthesis stimulation to deliver comprehensive skin brightening and structural support benefits.

Summary

antioxidant skin conditioning humectant antimicrobial pigmentation inhibitor

Science

Mechanism of Action

Works through dual pathways: inhibits melanin synthesis and distribution in melanocytes while simultaneously upregulating laminin-5 and collagen IV production in the dermal-epidermal junction. Additionally provides antioxidant protection through ROS neutralization and delivers temporary pore-tightening effects via astringent properties.
