"Fading discoloration from acne spots on my face is a constant struggle for me — I try practically every brightening product that comes within arm's reach. So, when I find one that really shows me a noticeable difference, like the Isdin Pigment Expert Ampoules ($38), I hold onto it very tightly. It's designed to brighten discoloration from UV exposure, ageing, pollution, and blemishes. Each ampoule contains enough serum for two uses, and it comes with a protective tube to make opening it easier." — JH
