Once you’ve applied tan to your whole body, let it dry for a few minutes, or until you feel the product has fully soaked into your skin. Then, put on loose clothing (a baggy t-shirt, boxer shorts, etc.) and let it set for a few hours, or overnight.
Letting it set overnight makes this process a whole lot easier because you won’t be exercising or sweating while the tan is on. Plus, you don’t have to worry about tanner getting on your good daytime clothes.
Each tanning product is different, so be sure to check the label for the ideal setting time. Most of the time, letting the product sit longer than the allotted time won’t do much, but cutting it short may result in a lighter tan than expected.
