To help avoid getting acne from being in the dirty and sweaty gym during the summer, I found a really helpful and easy remedy to keep my skin clean and clear (:
After the shower (when your skin is clean and pores are open) squeeze lemon juice all over your face and then rinse with really cold water!!
The citrus kills the bacteria in your skin and the cold water closes your pores so no new bacteria can get into your newly cleaned out face! Be sure to complete your skin clearing treatment with a layer of moisturizer! Its best to avoid doing this treatment more than 3 times a week because it could actually dry out your skin in the summer heat!
This whole process DOES WONDERS and only takes 30 sec to do (and 1 min to clean up/prep: cutting a lemon in half). Its vegan, organic, fresh, not too expensive, free of chemicals, and completely natural! Also, you can do it anywhere on your body!
