Give your skin a deep drink of water with the Madagascar Centella Hyalu-Cica Blue Serum. This ultra-hydrating "blue serum" is a cult favorite for a reason—it targets the deeper layers of the skin to eliminate "inner dryness" (that tight feeling you get even if your skin looks oily). With a cooling, gel-like texture, it instantly soothes irritation while pumping the skin full of moisture for a bouncy, glass-skin finish.
