Human Sebum Plug (Not an insect)

Typically found on human skin, often originating from pores on the face, scalp, or back.

N/A (This is a non-living accumulation of skin oils and cells, not a living organism).

Stationary. These plugs forms slowly over time as sebum (oil) and dead skin cells accumulate and harden within a hair follicle or pore.

Benefits: None, though removing them can feel satisfying to some. Risks: Generally harmless, but squeezing or picking at skin to remove them can lead to inflammation, infection, or scarring (acne).
