My experience: While a generally low carb diet (esp no grains) dramatically improved my psoriatic arthritis 10 years ago...2 years on stricter low carb (under 30, climbing the ladder this last 3 months to under 50/60g) has done nothing for my skin.
Sigh

I’m not complaining though. I ve had psoriasis for 25 years, mostly elbows, back and scalp. As long as it stays off my face and hands I’m not complaining. It gets less when I’m not working...maybe I’ll go into remission at retirement!

I’m glad to hear that others get clear, though. There’s always hope!
