Sebum is an oily substance made of fats. Sebum isn’t all bad since it helps protect and moisturize your skin and keep your hair shiny and healthy.
Too much sebum, however, may lead to oily skin, which can lead to clogged pores and acne. Genetics, hormone changes, or even stress may increase sebum production.
The following are often associated with oily skin:
- Enlarged pores
- Dull or shiny, thick complexion
- Blackheads, pimples, or other blemishes
