4 in 1 Serum - 30mL

This 4-in-1 serum combines Arbutin, Hyaluronic Acid, Vitamin C, and Ceramides—ingredients that have been studied for their potential roles in supporting skin hydration, barrier function, and overall skin appearance.

Arbutin has been studied for its potential involvement in skin tone–related pathways and pigment-regulating processes. Hyaluronic Acid has been explored for its potential role in supporting moisture retention and hydration within the skin’s extracellular matrix. Vitamin C has been researched for its potential involvement in antioxidant activity and collagen-related signaling pathways. Ceramides have been studied for their potential role in supporting the skin barrier and lipid structure integrity.

This combination continues to be of interest in skincare research examining hydration support, barrier maintenance, and skin appearance–related biological processes.
