What causes sebaceous filaments?Updated a year ago
Sebaceous filaments form because of the skin’s natural oil production and dead skin cell shedding process. When dead skin combines with sebum it becomes sticky and paste-like. It can stick to things, including to the “peach fuzz” hairs that grow out of your pores.
The dead skin and oil mixture can harden at the surface of the skin, forming a visible little clog or bump. This is especially common in areas with more oil production or larger pores, like the nose and inner part of the cheeks. In other cases, dead cells can struggle to shed as a result of skin dehydration, which can cause a high concentration of very small sebaceous filaments in one area.
