Question: what are the little black dots on my inner thigh?
Answer: How to Treat and Prevent Blackheads on the Inner Thighs. A blackhead forms when the opening of a hair follicle (pore) gets plugged with dead skin cells and oil. This blockage causes a bump called a comedo. When the comedo is open, the clog gets oxidized by the air, turns dark, and becomes a blackhead.
