Sebum

Sebum is a complex mixture of lipids produced by the sebaceous glands in your skin. Its primary function is to moisturize, protect, and waterproof the skin and hair. While essential for a healthy barrier, overproduction of sebum (often influenced by hormones or harsh cleansers stripping the skin) leads to an oily complexion and clogged pores. A balanced routine hydrates the skin, signaling the glands to normalize production.
