I'm turning 30 this year and after another breakout I thought I would turn to the forums for help. Over the years I've tried various regimes and made a few observations...

My Acne - I've had acne on my face since I was 14/15, I did nothing about it in the early years and just lived with it. As I got older and went to uni I become more and more aware of my looks. I used to skip lectures some days and hide in my room as it was so bad. For a couple of years I also got it on my back and shoulders but its since gone. After uni and various topical and oral drugs I went onto Accutane. It worked really well for me and despite a break out 3 months after it really reduced my acne for a couple of years. The problem is over the last 8 years its slowly got worse again and im almost back to where I was. The worst areas at the moment are my jawline, the crease between my chin and mouth and around my mouth.

My Body - I'm a fit and healthy person (although a little skinny) and recently ran a marathon but there are a few things ive noticed about my body that may contribute to acne. Firstly I have a very high metabolism, I eat fast, poo 2/3 times a day and never put on weight despite eating rather a lot compared to my friends. Secondly I have a fast paced life, I walk fast, do things quickly and never like to chill. This contributes to me being sweaty at times and very sweaty in hot weather, I often find my feet, groin, bum, arm pits and back are moist. This sometimes causes various skin conditions around my body, I get eczema on my feet and sweat rash on my groin area both of which are easily manageable, but does it cause my acne and how do I stop it?

My Family History - My Dad had acne as a teenager and my brother (28) has light acne on his face and severe acne on his back/shoulders/chest. Its obvious acne runs in my family but why and can it be fixed? My brother is also a bit sweaty and has oily skin.

What Ive tried - Creams, oral medicines, Accutane, Vitamin B5, Zinc, Vitamin C, Tea Tree none with much success. The only thing that seems to reduce my acne is sunshine.

Current Regime - Currently I wake up, prick any severe whiteheads with a pin (I don't squeeze), shower and wash gently with Clearasil for Sensitive skin, towel dry, moisturize with Clean & Clean Oil Free Daily with a drop of tea tree oil. Once dried I use a Witch Blemish Stick to cover any large red spots. I run a business and hated going to meetings covered in acne, the blemish covers gives me a little confidence back but it can only do so much. I repeat the same at night but without the blemish cover. I take a multi vitamin in the morning with a Zinc then another zinc at night.

What Next? - So with all the above info what do I do next? One option im considering is a Food Intolerance test with Yorktest which costs 300 but is it worth it? What is the family link? Is it because I sweat so much? Is it because my metabolism is so fast my body cant deal with the food?

Any advice anyone can offer?
