Inspired by the brands best-selling Banana Bright Eye Crème, the Ole Henriksen Banana Bright Vitamin C Serum (£53) promises both instant and long-term brightening effects. It contains soft yellow pigments that upon application, immediately make your skin look more luminous, while the potent blend of 15 percent vitamin C, 5 percent polyhydroxy acids (PHAs, these break up dead skin cells that would otherwise impede vitamin C from being absorbed), and hyaluronic acid provide long-term benefits by helping to fade bright spots, smooth uneven texture, soften fine lines, and hydrate — all of which contribute to a more radiant-looking complexion.
