Anti-aging Skin Conditioning Epidermal Repair Pigmentation Regulator Sebum Control

Science

This ingredient operates through several biological pathways: it stimulates collagen synthesis and boosts the content of Loricrin (LOR) to fortify the skin barrier. It accelerates cellular turnover and epidermal differentiation to smooth wrinkles, while simultaneously inhibiting melanogenesis to correct pigmentation and reduce skin yellowness. Additionally, its natural composition helps regulate sebum production for a balanced, mattified finish.
