Sebum
The waxy, oily substance your skin naturally produces to lubricate and protect itself.
Sebum is a complex mixture of lipids — including triglycerides, wax esters, squalene, and fatty acids — produced by your sebaceous glands. These glands sit within the deeper layers of skin and release sebum through your pores onto the skin's surface. Everyone produces sebum; it's a normal and necessary part of how skin functions, not a flaw to eliminate.
Sebum plays a genuine protective role. It forms part of your skin's acid mantle, a thin film that helps maintain the skin barrier, limits water loss from the upper layers, and supports the skin's natural microbiome. The amount you produce is influenced by genetics, hormones, climate, and age. Production tends to be higher during adolescence and can shift throughout life.
Understanding your sebum output helps you choose products that work with your skin rather than against it. If your skin tends toward higher oil production, lightweight, non-comedogenic moisturisers and gentle cleansers can support balance without stripping the barrier. Harsh products that strip too much oil can leave skin dry and irritated, which can make it feel oilier — though there's little evidence that stripping actually makes your glands produce more sebum. If your skin leans drier, richer formulations with occlusives or emollients can complement what your sebaceous glands provide naturally.
It's worth knowing that sebum production alone doesn't cause breakouts — it's one factor among several, including how skin cells shed and the bacteria present on the surface. If you're finding that excess oiliness is persistent and accompanied by ongoing congestion or discomfort, consider speaking to a skincare professional who can assess what's happening beneath the surface. There's no universal "right" amount of sebum, and working gently with your skin's natural tendencies tends to give better long-term results than trying to shut oil production down entirely.
