Packed with hyaluronic acid and antioxidants, Tan-Luxe Super Glow Hyaluronic Self-Tan Serum (£35) is a beauty editor favourite. It adds a Summer glow to your complexion all year round, without drying or clogging your skin. In fact, thanks to the hyaluronic acid, it leaves skin as supple and moisturised as any traditional HA serum on the market.
