Your skin type and/or how you take care or your skin after the application determines the length of your tan. As you lose your skin layers you will lose your tan. Losing the layers from your skin is a natural process this comes from showers, tight clothing, rubbing your skin, and dry skin. That is why we recommend you MOISTURIZE, MOISTURIZE, MOISTURIZE! The more abrasive you are to your skin the sooner you will lose you tan. The average tan lasts 5-7 days or more. We recommend our tanning extender lotion. Our lotion has the same DHA in it, but a smaller amount. It helps to keep you tan longer, evens out fading and prevents any dry patches. It's a great product to go with your spray tan. $20.00/bottle.
