Our latest kit makes easy work of skin cycling – a way of applying skincare on a four-nightly rotation for maximum benefits. Containing two must-have actives – glycolic acid for exfoliating and retinol for collagen production and to target pigmentation, fine lines, marks and blemishes – as well as hydration to replenish skin on non-active nights. Ideal for all skin types, but particularly blemish-prone and dull, pigmented skin. What's included?
