Acne HELP!

W
Y'all I'm really needing help with these horrible breakouts. I'm almost 30 I thought I would grow out of this by now. The only thing that has ever helped has been Proactiv but I hate the thought of spending $70 every time I need it. I'm currently using Cerave cleanser with my clarisonic, cetaphil moisturizer, and in the morning I use neutrogena. Tea tree oil for my breakouts. What am I doing wrong?!?
