Here’s some more info on the Demodex mites, which I believe are related to GD.

An elongated parasite, Demodex "sit with their heads down in the sebum-containing pore utilizing human sebum as a nutritional source. The mites release their waste products, which are composed of free fatty acids, into the pore and surrounding tissues, which are extremely irritating," Draelos explained. "Free fatty acids are released not only by Demodex, but also by bacteria like Proprionibacterium acnes, which is the causative agent in acne. It's interesting that all organisms that utilize sebum as a nutritional source release free fatty acids, and providing a common pathway for inflammation, not only in rosacea, but also in inflammatory acne and in the facial erythema and desquamation associated with seborrheic dermatitis."

Has anyone tried Ivermectin (Soolantra) for their Grover’s Disease? It is getting more popular for treating rosacea as it targets the mites. Some doctors prescribe an antibiotic with Ivermectin to make it work better.
