Human Skin Sebum Plug (or Keratin Plug)

Natural Habitat

Human skin pores, particularly on the nose, chin, or oily areas of the face.

Diet & Feeding

N/A (Not a living organism)

Behavior Patterns

These are plugs formed from a collection of dead skin cells (keratin), bacteria, and oil (sebum) that naturally accumulate within hair follicles. They are stationary and non-living.

Risks & Benefits

No health risk. They serve a biological function by helping channel oil to the surface of the skin to moisturize it, though they are often removed for cosmetic reasons. Incorrect removal or squeezing can sometimes lead to inflammation or acne scarring.
