Contrary to popular belief, getting a tan on your face does not make pimples better. It actually can make them worse. Initially, you will see a drying effect to your skin and the tan will conceal your pimples, but that is a only a temporary effect . The UV rays actually stimulate your oil glands to increase oil production also causing a thickening of the outer layer of your skin. This can block your pores and lead to breakouts.
