Compared to the 80s there are so many better treatments available now. Back then they just greased you up like a channel swimmer and hoped for the best.
I’ve been on Humira for 5 years now and it has totally changed my life as it’s the only thing that has truly worked for me.
I do think stopping smoking and reduced drinking has also helped but it’s also true that every case seems to be slightly different.
For beard wearers I’d recommend rubbing protopic ointment or Vaseline into it when still wet.
I also strongly agree with those who suggest not using soap at all.
I’ve had this shitty condition for 39 years now and there is such a better array of treatments available now so do take the time to see a GP if you can and good luck.
