Fake-tan brand Isle of Paradise not only leads the conversation in body positivity, but now they're leading the pack when it comes to sustainability. This year, they introduced new refill pouches in a pledge to reduce plastic waste. The new Isle of Paradise Refill Pouches (£15) are made with a whopping 81 percent less plastic than the bottles of self-tanning water. Not only that, the packs also save you money — £4 less than a brand new bottle, to be exact. With the easy-to-use refills, simply pour the pouch into your original tanning water bottle, twist the bottle cap to seal, and spritz away. And like all of the Isle of Paradise products, the tanning water is vegan and cruelty-free.
