The specific lipid profile includes: Triglycerides: The primary component, which are broken down by surface bacteria into free fatty acids. Wax Esters: Contribute to the stability of the sebum and possess antioxidant properties.
Cortisol's Impact on Sebum Production and Skin Oil Balance
The enzyme 5-alpha reductase converts testosterone into dihydrotestosterone (DHT), which binds to receptors in the sebaceous gland, stimulating cell growth and lipid synthesis. The accumulated sebum is subsequently excreted into the hair follicle, where it travels to the skin’s surface, forming a protective film.
The Specific Lipid Profile Not all sebum is created equal; its composition is dynamic and influenced by genetics, age, and hormonal fluctuations. Cleansers with salicylic acid can help dissolve excess oil within the pores, while retinoids normalize cell turnover and prevent follicular hyperkeratosis.
How Stress-Driven Cortisol Elevates Sebum Production
This gland is holocrine, meaning that the entire cell disintegrates to release its lipid-rich contents. When excess oil mixes with dead skin cells and environmental debris, it can clog pores, creating a plug known as a comedone.
