Other self-tanning tips to keep in mind.  Before using a self-tanner, you should put moisturize. Continue the preparing procedure by using a moisturizer after exfoliating your body. You shouldn’t use self-tanner without first hydrating your skin, since neglecting this step might result in spotty color. After bathing, wipe yourself dry with a towel and use body lotion to make your skin feel smoother, which may make applying self-tanner simpler.
