Customise your tan with Self -Tan Drops Sunlit Bronze. You simply add a few drops to your favourite The Body Shop moisturiser and gently rub into your skin for a gradual, easy-to-build natural tan. Formulated with DHA, you build the intensity you wish, for that lasting, sun-kissed feeling, all year round. The tanning effect becomes noticeable from around 8 hours after application and continues to develop up to 24 hours depending on the amount applied, before gradually fading over time.
