Step 1: Use a body scrub to remove all dead skin and cream residue. Step 2: Apply it to your desired body area with generous and long, stroking movements on an application mitt. Step 3: For a long-lasting dark tan, rinse off the skin after 1 hour. For a particularly dark tan, leave the foam on the skin for 2-3 hours. Shower with warm water and gently pat the skin dry.
