Skin: what is sebum, how to regulate excess?

Sebum is an essential element for maintaining good skin hydration , provided it is of good quality and produced in the right quantity. When it is out of balance, the skin can become shiny, mark more quickly and thicken. When it is harmonious, it protects, softens and helps the skin barrier remain supple and comfortable.

Sebum

Sebum is an oily substance secreted by the skin , and more precisely by its sebaceous glands. These glands, located in the dermis (the layer located under the epidermis), are more or less numerous depending on the area.

They are found in large quantities in the T-zone of the face (forehead, nose, chin): this is why this area often shines more and presents blackheads more easily. Conversely, the palms of the hands have almost no sebaceous glands.

What is sebum used for?

Sebum plays a key role in skin balance and hair vitality. After its production by the sebaceous gland, it rises through a channel to the surface of the skin, where it flows out through the pore . From there, it fulfills several fundamental functions:

• Form the hydrolipidic film : by mixing with sweat, sebum forms a protective barrier that limits water evaporation and helps the skin remain supple and comfortable.
• Protect the skin ecosystem : its fatty acids help maintain a slightly acidic pH, less conducive to the development of unwanted germs.
• Nourish keratin fibers : sebum uses the same orifice as hair; it lubricates them, gives them shine and protects them from drying out.

What is seborrhea (excess sebum)?

When they go into overdrive, especially during puberty, the sebaceous glands can produce more sebum than necessary. This is called seborrhea . This phenomenon is typical of combination to oily skin and can manifest itself as: diffuse shine, dilated pores, blackheads, uneven skin texture and sometimes a scalp that quickly becomes oily.

Why does sebum become too abundant?

• Hormones : The main cause of excess sebum. Androgens during adolescence or progesterone during pregnancy stimulate the activity of the sebaceous glands; some blemishes and shine are then common.
• Genetics : Some skin is hereditarily oilier. Tobacco, alcohol, fatigue, stress, and the environment (sun, wind, pollution) can accentuate this tendency.
• Unsuitable cosmetics : Cleansers that are too harsh attack the skin; in response, it produces more sebum to defend itself.
• High doses of sun : Prolonged exposure to the sun first dries out the skin; then the body compensates by overproducing sebum to avoid dehydration.

What are the consequences of excess sebum on the skin?

Beyond shine, excess sebum can clog pores. Dead skin cells are less easily removed, bacteria proliferate, and this can develop into acne , an inflammation of the hair follicle. Shiny, uneven skin can then become more sensitive and reactive.

Gentle tips for regulating sebum production

The goal is not to “dry out” the skin, but to balance it. A comprehensive approach (healthy lifestyle, appropriate care, simple actions) offers lasting results, while respecting the skin barrier.

1. Cooking & Hydration: Nourish the skin from within

Balance starts on the plate. For skin that breathes and “finer” sebum:

• Focus on vitamins B6, A, E, omega-3 and zinc (oily fish, eggs, colorful vegetables, oilseeds, whole grains).
• Limit fast sugars and poor quality fats that fuel inflammation.
• Drink 1.5 to 2 L of water per day: dehydrated skin can… overproduce sebum.

2. Minimalist and effective skincare routine

• Gentle cleansing morning and evening : a non-stripping, pH-friendly gel or milk. Once a week, a very fine scrub to smooth without irritating.
• Morning : a light cream with sebum-regulating active ingredients to gently mattify.
• Evening : a formula with AHAs (fruit acids) to refine skin texture and reduce blackheads.
• Essential hydration : yes, even for oily skin! Fluid, non-comedogenic textures help the skin rebalance.
• Scalp : in case of seborrhea, choose a shampoo specifically for oily hair and gradually space out washes.

3. Let the skin breathe

One day a week without makeup allows pores to relax and skin to regain comfort; the complexion appears fresher, shine is reduced.

4. Stress management & lifestyle

Stress can modulate hormonal activity and sebum quality. Deep breathing, regular sleep, gentle activity (walking, yoga): these habits soothe the mind and are reflected in the skin.

Supplements & skin: help to support balance

When lifestyle and skincare are well established, targeted supplementation can support the skin over time. To take stock of the format, here are the advantages and disadvantages of gummies (compared to other forms).
