No, you should not shower immediately after tanning. Bronzers and other tanning bed treatments are intended to stimulate melanin formation, resulting in darker tans. Washing away these bronzers and lotions right after tanning might diminish their efficacy, and your tan may not be as dark as it could be. The best thing to do is let your skin breathe after it has been exposed to the sun. As soon as you can, wash your face and body with a gentle soap. Do not use exfoliants or scrubs because they will remove the outer layer of skin, which could leave you vulnerable to sunburn. If you must rush out of the house after getting a tan, at least wait until the next day to take a shower. Your body will still be warm from the sun, so that should help speed up the process of cooling off.
