Start by applying a small amount of self-tanner to the center of the back applicator, and then hold one handle in each hand behind your back. Use a back-and-forth motion to spread the self-tanner evenly across your skin, working from the middle of your back out to the edges. Be sure to blend the edges carefully to avoid any streaks or uneven areas.

Repeat the process until you achieve your desired level of colour, and then wash the applicator with warm water and mild soap before storing it for your next use.
