I'm usually on here asking for advice so for once I'm in a position to give some; about time I returned all the favours tbh!
I'm 43 and for the last year(ish) have suffered really bad outbreaks of cystic acne, particularly in the 2 weeks running up to my period.
As the spots are so HUGE and DEEP and painful, they really don't go anywhere, just rumble horrible and boil-like deep below the surface for about 10 days, then take about 10 days after that to recede, and them my cycle hits the mid-end point and it all starts up again. Joy.
I noticed a big improvement in the summer when for random reasons I had no dairy produce for about 10 days.
Back on the dairy produce after that - cystic lumps all over again...
So, for the last month, I've had absolutely NO DAIRY, as an experiment.
And... (drum roll)
...My period is due tomorrow and I have just ONE medium-sized spot, right on my jawline.
It's easily squeezable (sorry TMI) rather than deep deeeeeeep below the surface and I've been able to easily cover it with concealer (previous spots are so lumpy that even if concealer hides some redness, skin is distorted beneath it so it still looks terrible).
It's a massive, massive improvement. Past months I'd have about 4 huge boils by now, on chin and near mouth, that would bubble up over about 5 days then linger for another 10.
Not sure what to do next as I love and miss my dairy produce - I love a yogurt, me, and I don't want to just cut out a whole food group - but maybe others who've tried this have further advice? Perhaps I can go back to small amounts.
I will probably need a calcium supplement too, I guess, if they're any good.
Anyway, I just wanted to put this up here as I know there are users of this board who have cystic acne too. I had it far worse in my late teens/20s and ended up on Roaccutane which was a godsend but as recently it's been obviously hormonal I didn't want to go down that route yet.
