    Wait, 0.3mm is huge, you should be able to see that. I don’t think this is right.

      Agreed. 1/64th of an inch is .016". An average human hair is .003" in diameter, that would be as long as five hairs wide. You wouldn’t even need a magnifier to see the largest ones.

      Combine the size with the fact that they are semi transparent and live in hair follicles and sebaceous glands, both of which are essentially under the skin, and that’s why you don’t generally see them.
