Global tanning brand St Tropez has introduced a free Tan Mirror App (available from the App store or Google Play), which helps customers try the full St Tropez product range before buying.

Using bespoke technology, the app showcases what every product will look like on individual skin tones. Users simply take a selfie and tell the app how much preparation time they have. It will then recommend a selection of suitable products that they can 'try on' to see how it would look in real life - whether it's one application of Dark Mousse or two days using Gradual Tan. The company believes that it will help customers buy with confidence. 

Users will also be encouraged to share their 'bronzed godess look' as the app can upload any saved selfies straight to social media (tagging @sttropeztan and #SHOWTHATGLOW).
