Touted for their ability to even skin tone and boost radiance, vitamin C serums are an essential step in many of our routines, including Sienna Miller's, who sings the praises of this glow-giving, facialist-made formula.
Whether you're looking to smooth fine lines or tackle irritation, a serum is a great way to add a targeted treatment to your everyday skincare steps. The best hyaluronic acid serums, for example, are ideal for tackling dry skin, as they help to lock in moisture and maintain a healthy skin barrier. The best vitamin C serums, on the other hand, work to brighten your complexion, fading the appearance of hyperpigmentation, for even and radiant-looking skin. So essentially, they can be quite the game-changer if you want to banish dullness and achieve a lit-from-within sort of glow. Especially, it seems, in the case of Sienna Miller's go-to formula.
