This St. Tropez Self Tan Purity Vitamins Face Serum ($30) has hydrating hyaluronic acid alongside vitamins C and D
to offer a sun-free glow, adding radiance to skin no matter the season. There's also an active tanning agent inside to aid with a deeper glow when this is worn under makeup or mixed with moisturiser. (The new St. Tropez Self Tan Purity Vitamins Bronzing Water Body Mist ($42) can bring similar moisturising and tanning effects to the rest of your body.)
