James Read Glow20 Facial Tanning Serum (£25) is the ultimate hard-working self-tanning serum as it develops in as little as just 20 minutes both thanks to the DHA (the sugar that reacts with proteins on your skin's surface to causes it to turn bronze) and ingredients like vitamin C, hyaluronic acid, and aloe vera in the formula — the latter of which help keep your skin hydrated and bright. The best part, though? This serum is meant to fit in with the rest of your skin-care routine, not add an extra step, as you can apply between your cleanser and moisturiser.
