What it is
Sebum is an oily substance produced by sebaceous glands in the skin. Its primary role is to lubricate and protect the skin and hair, keeping it moisturised and preventing it from drying out. Although it is essential for maintaining a healthy skin barrier, too much or too little can lead to various skin concerns.
Sebum is made up of a mixture of fatty acids, triglycerides, wax esters, squalene and cholesterol. It is secreted by sebaceous glands, which are located throughout the skin, particularly on the face, scalp, chest, and back. The amount produced is influenced by factors like genetics, hormones, diet and skincare habits.
How it works in skincare
Excess Sebum can lead to oily skin, clogged pores and acne.
Insufficient Sebum causes dry, tight and sensitive skin.
Balancing Sebum
Oily Skin: Use oil-free products and ingredients such as niacinamide or salicylic acid.
Dry Skin: Opt for richer moisturisers and hydrating ingredients such as hyaluronic acid.
Hormones can also influence levels of production, leading to fluctuations during puberty, menstruation, pregnancy or menopause.
