To complete your tan, Step 3 products help replenish moisture and nutrients lost to the skin during UV-exposure. The use of a step 3 product should follow every tanning session, whether you are in the beginning or advanced stages of tanning. By keeping your skin moisturized and conditioned you will help protect the longevity and radiance of your tan. For best results, use a Step 1 or a Step 2 product during every tanning session, and apply a Step 3 Extender daily after tanning and/or bathing to complete your tanning regimen and lock in results.
