Since you can’t know if they’re there or not, you won’t know if anything kills them or not. So, no matter what you do you’ll imagine them having sex on your face all night and engorging themselves on your skin oils then pooping on you. These are things that can’t be unthought. Sorry man.
One compound is terpinen-4-ol which is a primary constituent of tea tree oil. Several products containing terpinen-4-ol exist to treat rosacea and ocular rosacea such as Cliradex and Oust Demodex.
Study of commercial terpinen-4-ol products against mites:
Even parasites that are definitely detrimental are generally not especially bad for hosts that have coevolved with them. Hookworm in the American South was completely debilitating for the impoverished whites it infected, but basically a nuisance for the blacks. This is generally how parasites work.
So there would be much more cause for alarm if you believed that your face mites were a variety you weren't already adapted to.
One of the things I find most interesting about the whole N. Americanus affair is that hookworm was a public health disaster of colossal proportions, and the medical research that recognized it was a big, important advance... but medical treatment for the problem is mostly irrelevant. The (very successful) "medical" intervention that solved this problem was just convincing people to wear shoes.
That's not saying much - just means that we can live until we can breed, and that the next generation also makes it somehow. The same thing could be said about any illness, drug, disaster or mis-treatment that ever happened.
Ivermectin is an amazing drug all around. Very safe and useful in so many circumstances. It’s a great shame that it got politicized, first by people who took it unnecessarily because they didn’t trust the establishment, and then by the media and politicians, who badmouthed Ivermectin in order to dunk on the first group. Very sad.
Definitely not a joke. I use Ivermectin cream to control Rosacea and it works well. The goal isn’t to eliminate them but to prevent overgrowth which is likely what causes most Rosacea.
