The allergy, called alpha-gal syndrome, came to light a little over a decade ago.
Eczema: For years I was dependent on prescription topical steroids. Then I tried giving up soap. I no longer suffer from eczema.
Briefly went back to using soap during COVID. Had a flare-up within a week. Haven’t used soap since, except in the rare occasion I have something specific on my hands (machine grease or something) I want to get off.
