My skin is breaking out ! what should I do ? URGENT?

I hate that I breakout during summer Grrrrr.... Just the time where you don't want to wear makeup ... I used to use harsh things on my skin and it never really worked like I wished so I started using gentle stuff and that really helped drastically because I found out my skin was sensitive .. I've added isopropyl alcohol as a toner to my routine and that worked out amazing! 2 weeks later I'm breaking out crazy ! :( on my for head, pimples on my cheeks etc ... I don't know what to do anymore ?! :O
