So, how does it all work? Firstly, you can select one of three Dramatically Different hydrating bases — the hydrating jelly, the signature moisturising lotion or an oil-control gel. Next up, choose one of five rainbow-hued active concentrate cartridges, which all address a specific skin type. There's Irritation, infused with white tea leaf extract to soothe, Pores & Uneven Texture packed with AHAs to retexturise skin, Lines and Wrinkles containing whey protein, Fatigue feat. taurine to regain your glow, and Uneven Skin Tone, which brightens up your complexion courtesy of angelica root extract. Finally, the colourful cartridge slots neatly into the base, distributing the right dose of each, every time.
