Having Problems On Acne?

With the weather changes here in the US my acne is appearing especially on summer. That is why I always avoid to stay under the sun because my skin started to get dry and I can see some rashes come out. But one of my biggest problem is my face when its summer because when I sweat a lot, my face is itchy and it turn into an acne. I always have an acne cream when its summer because its the only season you can see my acne. However, when I put some cream on, it goes quickly! It's amazing isn't?
