Sebum filaments are actually a result of sebaceous gland activity. They are composed of sebum, excess oil, dead skin cells, and dirt. These filaments typically reside deep within hair follicles or may extend slightly above the skin’s surface. They appear opaque white or ivory white, have a soft texture, and are often easy to remove with light pressure.
