Accelerators are your basic tanning lotions. Their sole purpose is to speed up the tanning process by boosting melanin production and moisturizing. Using an accelerator will help you get the tannest your skin will “naturally” be. To get darker than what you can normally get, you may need to select a different type of lotion with advanced tanning ingredients. .
