How is sebum secretion regulated?

Question

The principle of homeostasis in biology says that living organisms try to maintain some sort of equilibrium. Doing that requires the use of feedback mechanisms to regulate things like temperature, salinity, etc. Are there any feedback mechanisms the body uses to regulate the output of the skin's sebaceous glands? If so, what are they, and on what timescale do they operate?

Answer 1

Metabolic pathways are the primary regulators of human sebum concentration and secretion. Given their control by hormones, the timescale ranges from small changes over hours to large changes over the course of puberty.
