I have chronic acne, don’t think I’ve woken up to ‘normal’ skin since I was 11
Have tried most topicals - BHA, AHAs, benzoyl peroxide, antibiotics, etc some of which helped but I’ve never had clear skin
I follow a low carb diet, (not keto but low carb) to try and help but still have acne
Previously tried eliminating dairy didn’t help either
I think as it’s hormonal diet and topical treatments alone won’t be enough...
I haven’t tried birth control but I’m so scared my skin will get worse afterwards, as I’ve heard a lot of cases where BC clears acne temporarily but once you get off it the acne comes back even stronger 
I have heard spironolactone is quite commonly prescribed in the US for women with hormonal acne, but not so much here in the U.K. Would love to know if anyone here has taken it, and what there experiences were
Also, did you have go private or is it available on the NHS
