Developed by celebrity tanning expert (and founder of the brand), Jules Von Hep, the Isle of Paradise Hyglo Self-Tan Serum (£22) is a gradual fake-tan serum that you can easily integrate into your everyday skin-care routine. Like most of the self-tan serums on the market, Hyglo contains hyaluronic acid, but what makes this formula so incredibly moisturising is the fact it also contains avocado, coconut, and chia seed oils that leave your skin glowing and help your faux glow last and last. "I really like it!" says POPSUGAR associate editor Tori Crowther, who has been using it for a couple of weeks. "It's very lightweight, but doesn't feel like it clogs up my pores. It really hydrates, but doesn't irritate my sensitive skin while giving me a tan, and it smells great. It doesn't have a horrid tan smell at all. I also love that it comes in an XL size so can add to body moisturiser, too."
