What is Sebum and Why Do We Need it For Healthy Skin?
Sebum is a word you've probably heard, but might not really understand — especially since it gets blamed for acne more than it gets credit for anything else. Here's what it actually is, why your skin needs it, and what to do if it's producing too much.
What Is Sebum?
Sebum is the natural oil your body produces, made in the sebaceous glands located in the middle layers of skin near hair follicles. What you see on your skin's surface is actually a mix of sebum and fat molecules (lipids), which combine to form a protective coating.
Your face, chest, and scalp carry the highest concentration of sebaceous glands on your body — your face alone can have up to 900 sebaceous glands per square centimetre.
Everyone produces sebum, but how much varies significantly from person to person.
What Affects Sebum Production?
Hormones — particularly testosterone — play the biggest role in how much sebum your skin produces. That's why oily skin and breakouts are more common during puberty, when the body is flooded with hormonal changes.
Sebum production generally slows as you age. That's not automatically a good thing — sebum does real work for your skin.
The Benefits of Sebum
Sebum gets a bad reputation because of its link to acne, but an overproduction of sebum is the actual problem — not sebum itself. In normal amounts, it does more good than harm:
It's hydrating. The fat molecules sebum carries to the skin's surface help lock in moisture, leaving skin more supple and flexible.
It carries antioxidants. Fat-soluble antioxidants like vitamin E travel to the skin's surface via sebum, helping protect against free radical damage from UV rays and pollution.
It has antimicrobial and anti-inflammatory properties. Sebum is slightly acidic and contains sapienic acid and other fatty acids that help block viruses and bacteria from penetrating the skin barrier — reducing risk of infection and calming redness.
What If You're Producing Too Much Sebum?
Oily or acne-prone skin doesn't need less oil produced overnight — it needs a routine that balances oil production without stripping the barrier, since stripping tends to trigger even more oil in response.
Our Antioxidant Moisturiser is formulated to hydrate without adding oil, helping regulate sebum rather than fighting it. For deeper pore-level oil control, the AHA/BHA Exfoliating Cleanser and AHA/BHA Resurfacing Serum target the buildup that turns excess sebum into breakouts. If you want the full routine, the 3-Step Clear Skin Kit pairs all three.
Frequently Asked Questions About Sebum
Is sebum the same as oil?
Sebum is your skin's natural oil — the terms are essentially interchangeable in everyday use.
Does washing my face reduce sebum production?
Over-washing or over-stripping can actually trigger more oil production as skin tries to compensate. A gentle cleanser used consistently works better than aggressive washing.
Why is my skin oily in some areas and dry in others?
Sebaceous gland density varies across the face — the T-zone typically has more glands than the cheeks, which is why combination skin is so common.
