I hope sharing my story with others may help them in some way. My journey with acne started around 25 years ago in my teens, I'm now 39. I've always had pretty clear skin on my face, just bad bacne (sometimes cystic and painful) and occasionally on chest. Made me horribly self conscious in certain clothing, at beach and god forbid, intimate with partners. Over the years, I've used oral contraceptive Diane (pretty good), taken supplements (not very disciplined, some made me break out horribly like fish oil!), had IGG testing (showed gluten and eggs), been vegan (not good), been almost Paleo (sometimes ok), so many things. I was convinced it was food and avoiding gluten and eggs helped but didn't clear completely. It was hard to pin point triggers as effect seemed to show about a week or so later, but this varied. Generally my diet is pretty good, full of whole foods, organic veggies from garden, ethically sourced meat, etc. I avoided dairy and drank soy milk for years. I ate more soy products when vegan (no longer), acne was bad then. I've been off the contraceptive pill for number of years (trying to conceive) and recently decided to stop soy milk as thought this might be affecting things in that area (not for acne purposes). Within a week, my skin had calmed significantly! I had to laugh (cry) at the irony of myself thinking I was so healthy drinking soy milk when it was giving me acne and probably contributing to infertility. I think I've narrowed it down to gluten, eggs and soy, and if I avoid these, I am pretty much clear. Sugar is bad too, although it generally accompanies the above. Small amounts of my trigger foods seem ok and I've decided not to be so strict that life becomes unmanageable (soy is in everything). This attitude has probably made it hard to pin point triggers but you also have to live andnot be obsessed, which is hard if you've ever suffered depression from acne. I acknowledge for some people, they must strictly avoid certain foods. IGG testing helped but can be very expensive (I'm in Australia and used Imupro). I would recommend elimination diet as best solution, as challenging as it can be, and you'll probably need to wait a week between each elimination to see results. Fingers crossed my approach will see results!
