To make your spray tan last as long as possible, avoid using products that chemically exfoliate skin cells, like retinol, glycolic acid and salicylic acid. Use a lightweight lotion daily to keep your newly tanned skin cells from flaking off prematurely.

Both salt water and chlorinated water will fade your tan faster, so keep that in mind if you're baring your new glow by the beach or poolside. If you do go in the water, pat your skin dry -- don't rub.

By following the above rules, your glorious spray tan will last seven to ten days.
