At first glance, sebaceous filaments may look like blackheads, but before you start squeezing them, you may want to take a closer look. Sebaceous filaments serve an important function of moving sebum from sebaceous glands to the skin's surface. This process helps lubricate your skin and keeps it naturally moisturized and is one of the main reasons you should leave them alone. So, how can you tell sebaceous filaments and blackheads apart? Unlike blackheads, sebaceous filaments tend to be sandy in color or light grey. On the other hand, blackheads have a darker color and appear when dead skin cells, bacteria, and sebum collect around the opening of your pores, forming a small bump called a comedo.
