Does anybody have any suggestions about how to get rid of adult acne?

I'm 30 years old and I have had moderate acne since I was 10 years old. Right about age 29 my acne started to clear and I was like "Score! I'm finally going to have clear skin!" On no particular regimen, my skin clear beautifully for about a year. Then, about 3 weeks after I turned 30, The acne was back worse than it had EVER been. It was not on my back & shoulders! I'm trying to be cool about it but its really killing my self esteem. I know I am a great person, but when I am out in public I feel like people are looking at my skin when they talk to me. It's honestly getting to te point that I don't want to go places. It seems the older I get the more scars my acne leaves. So now I'm battling the acne & the scars they leave behind (whether I pick at them or not). I am the only one in my family and the only one of my friends who still has acne. I have been to the dermatologist who admits that my acne is mild, but if that's the case why won't it clear up?! I've tried every acne medication that has an infomercial and currently I'm doing Pro Activ, previously on a strict twice a day Cetaphil cleansing with Benzoyl Peroxide 10%. My fam & friends are sweet, when they say "I didn't even notice!", but c'mon we all know they see it. LOL.
