I can really relate to this. I'm 45 and have always had bad skin especially on the chin in the later years (which I have heard is hormonal acne and I believe that since my hormones are going nuts right now). However, what I have really found that has completely cleared my skin in my opinion are three things - cleansing and masks: go to clareledor - she is my favorite - all natural things - I use her cleanser, toner and clay mask with jojoba beads for acne prone skin. She also has a super nice anti aging cream for acne prone skin which helps acne and also moisturizes but it does not make your skin greasy - mine is matte after using it. I just love love love all her products - they have really helped my skin. Also, the usual - lots of water, vegetables - stay away from junk food. And I think the most important also was taking probiotics - a really good one - I take it 3 times daily - look it up for skin - if your insides are messed up, it comes out in your skin and I won't be without my cleansing routine and my probiotics!
Good luck!
