We all know that a shower is a great way to wrap up a workout. However, not everyone knows that a thorough face wash before you exercise (as opposed to after) is the best way to keep your facial skin clean.

When you sweat during your jog, yoga class or any other activity, you don't usually think twice about wiping the sweat off your face. But, if you haven't washed your face before your workout, all the dirt, oil and debris you've been carrying around on your skin all day gets ground deep into it, clogging pores and causing blackheads.

However, there is nothing about sweat that causes breakouts. The sweat you produce is simply water, salt and urea (a great moisturizer).

So instead, if your face is clean before you workout, there is no dirt to clog your pores, and a splash of water after you exercise is all you'll need to feel fresh and know that your skin is clean.
