# Sebaceous Filaments

## Quick Summary

Sebaceous filaments are normal pore structures, not dirt. On the nose they can look like tiny dots because oil and skin-cell material collect in visible pores.

## Causes

Oil production, pore size, skin texture, lighting, and close-up mirrors can make filaments stand out. They can be minimized temporarily, but they refill because they are part of normal skin.
