Korean serums, ampoules and essences add targeted hydration and active ingredients to your routine. Essences usually have a lightweight texture that layers easily, while serums are designed to address specific concerns such as dehydration, uneven tone, texture or signs of ageing. Ampoules often provide a more focused formula, although the difference between an ampoule and a serum varies by brand.

Apply products from the lightest to the richest texture after toner and before moisturiser. Introduce one new active formula at a time so you can see how your skin responds and avoid overwhelming your skin barrier.
