I'm 16 years old and where I live is very cold a lot of the time, and I get pretty bad acne so I use face washes and pro-active, but I recently went to live with my dad for 2 months he lives in queensland where it has been very hot and I have been sweating a lot and my skin is completely clear I don't wash it up here but its perfect with no pimples or redness. Do you know why my skin is so clear and how do I keep it clear when I go back home? Thank you
