What Is Sebum? How Sebum Works & What It Can Do For You


The word "sebum" comes from the Latin word sebum meaning "fat". Sebum is a glandular secretion produced by the sebaceous glands in the skin. It helps to waterproof our skin and keep it hydrated and soft. Sebum also plays an important role in regulating our body's natural temperature, protecting against damage caused by free radicals, assisting the absorption of nutrients, regulating keratin production, reducing inflammation in response to infection, regulating sebum production (if necessary), and so on.

 Sebum is basically the oil that our skin produces naturally. It's a project that we have to deal with on a daily basis, because although it helps keep our skin looking good and healthy.

1) How do you produce sebum?

 The sebaceous glands produce sebum, a waxy, fatty substance that lubricates and protects the skin. Sebum is produced by the sebaceous glands and is found on the surface of the skin, including the forehead, cheeks, chin, and underarms. The sebaceous glands are attached to hair follicles in areas where facial hair grows.

Sebum production varies from person to person. Some people produce more than others, about 1 gram of sebum per day for most people but it can vary dramatically from person to person. Women produce more sebum than men do and tend to produce it at a higher rate during puberty or when they are pregnant or nursing. Women also have more sebum than men do because they have more hair follicles (the part of the body where new hairs grow) than men do on their bodies and face.

Sebum production is regulated by hormones such as testosterone and estrogen. Sebaceous glands are also more active during puberty when hormone levels increase.

2) What is the purpose of sebum?

 The purpose of sebum is to keep the skin moist and soft. Sebum also helps to protect the skin from bacteria by creating a protective layer. This layer prevents water loss and keeps the skin hydrated. Sebum is secreted by the sebaceous glands in response to hormonal changes, especially during puberty and pregnancy. These glands produce several different types of lipids (fats), including cholesterol, wax esters, and triglycerides. The main function of sebum is to act as a barrier between your skin and the environment, preventing evaporation as well as keeping it hydrated.

 The main function of sebum is to help prevent damage from ultraviolet radiation (UVR). When UVR hits our skin, it causes damage to cells in the epidermis (outer layer) which leads to a loss of moisture and dryness. Sebum helps restore this damaged tissue by filling in gaps in between cells so that there will be no more UVR damage occurring.

Sebum also acts as an important antioxidant in our body because it contains lactic acid which can neutralize free radicals produced from UVR from passing through cell membranes into our body's cells.

3) Do some people produce more sebum than others?

 The answer to this question is yes, some people produce more sebum than others.

The amount of sebum produced by our bodies depends on several factors including age, gender, and ethnic origin. In general, women have more sebaceous glands than men do, which means they produce more sebum than men do. However, there are exceptions to this rule: some women have less visible pores than others because they produce less sebum; some men have more visible pores because they produce more sebum.

 The production rate is affected by a number of factors including:

i- The level of activity: 

If you are very active, your body will need to produce more sebum as it has to keep up with all the activity.

ii- Lifestyle: 

People who live a sedentary lifestyle usually have less sebum production as their bodies don’t need so much extra oil for them to function properly.

iii- Genetics: 

Some people are genetically predisposed to producing more sebum than others and this can be passed on from generation to generation through genes that affect how much oil is produced in the skin.

 4) What are the benefits of sebum for skin?

The primary function of sebum is to keep the skin hydrated and healthy. It also helps in maintaining the pH balance of the skin, which helps in preventing any infection from occurring.

Sebum helps in lubricating the skin, which prevents friction between the hair follicles. The presence of sebum also acts as an antioxidant, protecting your skin from damage caused by free radicals.

Sebum can be found in almost every part of your body including your scalp and face. But it is primarily produced by sebaceous glands located at the base of hair follicles. The amount of sebum produced depends on how much moisture is present on your skin at that time.

5) How does sebum affect your hair?

 It's no secret that having oily hair can be a real bummer. And when it comes to the condition of your hair, sebum is one of the most important factors. But how does it affect your hair?

You can think of sebum as a natural conditioner for your hair. It's what helps keep your hair soft and shiny. But too much sebum can cause problems for your hair that you don't want to deal with:

i- Dandruff: 

Sebum may contain bacteria or yeast that contribute to dandruff. In fact, some experts say that dandruff is actually an inflammation of the scalp caused by an overgrowth of yeast cells in the follicles (nodes) of the hair shafts.

i- Acne: 

Seborrheic dermatitis (also known as 'dandruff') is often associated with acne because both share similar symptoms: flaky skin, redness, and crusting around the nose area and forehead areas that follow a seasonal pattern due to hormonal changes in puberty. If you have acne but no dandruff, this could mean you're missing out on treatment for both conditions if you don't address what's causing them first!

Your body produces oil every day — whether you're aware of it or not. Your brain makes about 45 ml of oil per day; that's only enough for a few minutes' worths of activity before you need water to lubricate things again. The rest comes from special glands in your face called pores (which sit just under your skin). These glands produce oil to keep skin smooth and prevent flaky skin caused by dry air or harsh chemicals like detergents and cleansers. Your body actually makes three types of oils: cerumen (ear wax), sebum (underarm/hairline), and sweat (all over).

6) Is there anything wrong with having a lot of sebum on your skin?

 The short answer is yes, there's something wrong with having a lot of sebum on your skin. Sebum is the natural oil produced by the sebaceous glands on the skin. It's normal for the skin to produce some amount of sebum, but if it becomes excessive and causes problems like acne or blackheads, it can be a sign that something else is going on.

So what's going wrong if you have too much sebum on your skin? Basically, there are a few things that cause excess sebaceous gland activity — hormones like testosterone, prolactin, and estrogen; irritation from shaving or washing; stress and illness; and underlying medical conditions like PCOS (polycystic ovary syndrome) or acne vulgaris (a skin condition).

7) The importance of sebum outweighs its negative reputation.

Sebum is the oily secretion that covers the skin’s surface, and it has been linked to acne, aging, and even dandruff. But this substance also plays a vital role in keeping skin healthy and protecting it from environmental damage.

Sebum is made up of two types of cells: sebocytes and desquamating cells. Sebocytes are the main producers of sebum, while desquamating cells help remove old sebum from the surface. Sebocytes produce up to 10 times more sebum than desquamating cells do.

It protects, lubricates, and moisturizes our skin. However, it does not prevent water loss but rather helps to maintain moisture balance within the skin.

Sebum also plays an important role in body odor control. It has antibacterial properties that help keep skin healthy and free of germs and bacteria. Sebaceous glands secrete sebum into hair follicles where it mixes with dead cells and bacteria on our skin surface to form a protective layer that keeps out dust and dirt particles as well as environmental pollutants like pollutants in the air we breathe.

The fact that sebum plays such an important role in keeping us healthy should make us consider using it more often instead of keeping it hidden under clothing all day long!


We hope that this article has been an eye-opening look at an often overlooked subject in the field of skincare. Sebum is something that exists within the skin of everyone and is vitally important to our skin's health. Understanding its purpose has helped us to better recognize when our skins are producing too much sebum or too little, and then take action to rectify these problems. In short, excess sebum production can lead to clogged pores and acne breakouts, while sebum deficiencies can cause dry skin and flaking. By keeping your sebum levels balanced, you can help maintain a healthy complexion for yourself for years to come.
