It is a type of skin secretion — the body's… ## What is sebum? Sebum is the natural oil produced by sebaceous glands that lubricates the skin and can accumulate in pores. It is a type of skin secretion — the body's own oily output, not something applied from outside. Across skincare writing the same substance goes by a few names: the plain-language term is skin oil, the location-specific version is facial oil, and the technical label is sebaceous secretion. All three point to the waxy, lipid-rich film that keeps the surface supple. Sebum is defined by what it is made of. Its main component parts are fatty acids, wax esters, and squalene, along with smaller amounts of other lipids. That mix gives sebum its slightly greasy, spreadable consistency — thicker than water, thinner than a solid wax — which is exactly what allows it to coat the surface and travel up and out through the follicle. A 2012 overview of [oily skin](https://pubmed.ncbi.nlm.nih.gov/22722766/) describes how sebum production shapes the feel and look of the complexion, and a 2025 review of [the sebaceous gland](https://pubmed.ncbi.nlm.nih.gov/40422250/) details the gland biology behind that output. ## Where sebum comes from and where it goes Sebum is part of facial skin, produced deep in the skin by the sebaceous gland and then pushed up along the hair follicle to the surface. The production rate is not fixed — it rises and falls with hormones, climate, and age, which is why one person runs oily and another runs dry. When output is high, the surface takes on a visible shine and oil can pool around pore openings. Interestingly, sebum is also a delivery route for skin lipids: a 2006 study found that sebaceous glands help [transport vitamin E to the skin surface](https://pubmed.ncbi.nlm.nih.gov/16477469/), so the same oily secretion that can look shiny also carries a natural antioxidant outward. The natural opposite of oily, sebum-rich skin is dry skin — a surface with too little oil, which can look flat and feel tight. Neither extreme is the goal; balance is. Sebum itself is protective and normal. It only becomes a cosmetic concern when excess sebum lingers where it should not. ## How sebum affects pores Sebum and dead cells are the two ingredients of a clogged pore. When excess sebum meets shed corneocytes at a pore opening, the mixture can thicken into a plug — the beginning of what people notice as [congested pores](/concepts/congested-pores). The oil is not the villain on its own; it is the combination of sebum in pores plus dead-cell buildup that makes a pore look enlarged or dark. This is why an oily surface so often reads as textured or shiny rather than clear. Regular, gentle exfoliation targets the dead-cell half of that equation. By lifting away the loose [dead skin cells on the surface](/concepts/dead-skin-cells) that would otherwise bind with oil, exfoliation helps keep pores looking clearer even on skin that produces plenty of sebum. It does not stop the glands from making oil — nothing topical and cosmetic should claim to — it simply keeps the surface from holding onto the mix. ## How the scrub helps oily-looking skin The Era Organics [Face Exfoliation Scrub](/products/face-exfoliation-scrub) works on the surface where sebum and dead cells meet. Its micronized rounded walnut-shell powder buffs loose flakes away, and its papaya enzyme (papain) loosens the keratin bonds holding stubborn cells in place, so the oil-and-flake mixture that dulls oily skin lifts off. Aloe vera and manuka honey then leave the freshly exfoliated skin looking smooth and comfortable rather than stripped. Used 2 to 3 times a week, it helps oily and combination skin look fresher and keeps pores looking clearer — a cosmetic result, about the appearance of the skin, not a change to how much oil the glands make. ## Frequently asked questions about sebum ### What is sebum and what does it do? Sebum is the skin's own oil, made by sebaceous glands from fatty acids, wax esters, and squalene. It lubricates the surface and helps keep it supple. In the right amount it is protective; in excess it can pool around pores and make skin look shiny. ### Does exfoliating reduce sebum? Exfoliating does not stop the glands from producing oil, but it lifts away the dead cells that combine with sebum in pores. Clearing that half of the mixture helps the skin look less congested and keeps pores looking clearer, which is a cosmetic effect on appearance. ### Why does my skin get oily? Sebum production rises and falls with hormones, climate, and age, so oiliness varies from person to person and season to season. Skin that runs oily simply makes more sebaceous secretion; gentle regular exfoliation helps keep that oil from settling into visible buildup. ### Is sebum the same as dirt? No. Sebum is a natural skin oil, not external grime. It only looks like a problem when excess oil mixes with dead skin flakes at a pore. Lifting those flakes away with a gentle scrub keeps the surface looking clearer without over-drying it. ## Era Organics and sebum The Era Organics Face Exfoliation Scrub is a dual-action cosmetic scrub that helps oily and combination skin look fresher by lifting the dead-cell buildup that mixes with sebum on the surface. It combines micronized, rounded walnut-shell powder with papaya enzyme (papain), then soothes with aloe vera, manuka honey, and vitamin E. It is made for facial skin and body, best used 2 to 3 times a week rather than daily. Because it contains walnut, a tree nut, and manuka honey, patch test first and skip it if you have a tree-nut or bee-product allergy. It is a cosmetic for the look and feel of your skin — for a medical skin condition, see a clinician.
