Detailed answer

Blackheads are clogged pores that contain oil, dead skin cells, and bacteria. They appear as small black bumps on the surface of the skin and can be inflamed or raised. Sebaceous filaments, on the other hand, are naturally occurring structures that help transport oil from the sebaceous glands to the skin's surface. They appear as greyish or tan, pin-like dots and are usually not inflamed or raised. While blackheads can be treated and minimized with proper skincare, sebaceous filaments are a normal part of the skin and cannot be permanently eliminated.
