Ya a chemical peel can definitely start Psoriasis including physical trauma. And when I say I think EC is maybe a manifestation of Psoriasis I'm not saying I think it is absolutely Psoriasis itself, but something very similar. Psoriasis can come on at anytime in someones life which makes me think about the stories of EC coming up out of nowhere. Inflammation is present like psoriasis and cell turn over rate is similar. From there the similarities kind of stop...but the underlying symptoms are what make me think this is psoriasis related.
