Sebaceous filament
Sebaceous Filament
Sebaceous Filament (/sɪˈbeɪʃəs ˈfɪləmənt/), derived from the Latin words "sebum" meaning "tallow" and "filum" meaning "thread", is a tiny collection of sebum and dead skin cells around a hair follicle, which usually takes the form of a small hair-like strand. They are most commonly found in the nose area, but they can also appear on the forehead, chin, and cheeks.
Description
Sebaceous filaments are a natural part of the skin's follicular system. They help to channel the flow of sebum within each hair follicle. Unlike blackheads, they are not a form of acne but are entirely normal. They are usually less than 1 mm in diameter and can be yellowish or grayish in color.
Function
The primary function of sebaceous filaments is to facilitate the movement of sebum from the sebaceous gland to the skin's surface. This sebum helps to moisturize and protect the skin.
