Esthetician's Guide to Sebaceous Filaments

This condition appears in the ASCP SkinPro app

What are Sebaceous Filaments?

A structure comprised of corneum cells, sebum, bacteria, cellular fragments, and one hair. 

What Should I Know About Sebaceous Filaments?

  • Look like tiny open comedones and are frequently called “clogged pores.” 
  • In oily skin, they have a waxy texture due to accumulated sebum when extracted. 
  • In older skin, they can resemble tiny dark hairs. 

Treatment Considerations for Sebaceous Filaments

  • Can be easily extracted by softening the areas with a desincrustation solution under steam. 
  • At home, salicylic and/or glycolic acid serums can reduce their appearance.
  • Sebaceous filaments will always reoccur since they are actually part of the sebaceous structure.
