If you regularly find yourself making spontaneous plans, keep the SKINSTANT Instant Bronzed Tanning Stick (£24.99) in your handbag for an instant and flawless glow. You can use it on smaller areas to contour or apply with a mitt and buff into wider areas wherever you want a bit of colour. This is the perfect option if you want a 24-hour tan that can be washed away with soap and water in a flash. Unlike lots of wash-off tans, this formula is totally splash-proof, sweat-proof, and water-proof, making it the ideal companion for parties, clubbing, gymming, and hitting the beach.
