Not an insect (Sebum plug, keratin plug, or skin fragment)

Found on human skin, inside hair follicles/pores, usually expressed onto tissue or towels during grooming.

N/A (This is a product of the body, not a living organism)

This object is non-living. It is often squeezed out of a pore (comedo) on the face, back, or scalp. It usually has a hard, waxy, or crystalline consistency.

Risks: None directly, though aggressive picking can cause skin infection or scarring. Benefits: Removing them can sometimes relieve pore blockage, though they often recur.
