How does demodex progress (please give a clinical description)?
The demodex disease, as a rule, tends to advance and propagate. On the skin around mouth, the hair follicles are on an inflamed background, there are papules (small dermal eruptions – small, dense nodules slightly elevated above the skin) and pustules (purulent spots), and the skin may be seen to peel. There are spots of what appear to be pink acne. You may see hair in and around the lesion. Ocular developing processes (blepharoconjunctivitis, an episcleritis, a keratitis, a serous iritis) are possible. Irritating sensations of crawling, and an itch at the center of the site of the lesion.
