What is Sebum and Why Does Your Skin Need It?

What is it?

Sebum is an oily, waxy substance produced by the sebaceous glands, which are found all over the skin except on the palms of your hands and soles of your feet. It's a complex mixture of lipids (fats) like fatty acids, triglycerides, squalene, and cholesterol. This natural oil coats, moisturizes, and protects your skin and hair. The highest concentration of sebaceous glands is on the face and scalp, which is why these areas can become particularly oily. Sebum's primary function is to form a protective barrier to prevent moisture loss and shield the skin from environmental damage.

Why is it trending?

The conversation around sebum has shifted in the wellness and beauty space. Instead of just focusing on eliminating oil, there's a growing understanding of its benefits and the importance of balancing sebum production rather than stripping it away completely. This trend is driven by a move towards supporting the skin's natural barrier. Skincare enthusiasts are now more interested in how to work with their skin's natural oils to achieve a healthy glow, rather than fighting against them. This has led to a rise in products and routines aimed at managing either overproduction or underproduction of sebum.

How does it affect people?

The amount of sebum your skin produces can significantly impact its health and appearance. An overproduction of sebum can lead to oily skin, clogged pores, and is often associated with acne breakouts. Conversely, too little sebum can result in dry, flaky, and irritated skin because the protective moisture barrier is compromised. Sebum production is influenced by hormones, particularly androgens, which is why conditions like acne often flare up during puberty when hormone levels surge. Finding the right balance is key; healthy sebum levels keep the skin lubricated, protected from infection, and moisturized.
