Sebum and skin care: A complete guide to balanced skin : Your online pharmacy selection

What is sebum?

Sebum is an oily substance produced by the sebaceous glands in the skin. It plays a crucial role in protecting and moisturizing the skin. Composed mainly of lipids, it forms a protective barrier on the skin's surface, helping to prevent dehydration and protect against external aggressors such as bacteria and pollutants.

Why is sebum important for the skin?

Sebum is essential for maintaining the skin's hydrolipidic balance. It prevents the skin from becoming dry and cracked, and contributes to its suppleness and softness. It also has antibacterial and antifungal properties, helping to prevent skin infections.

What causes excessive sebum production?

Several factors can lead to excessive sebum production:

• Hormonal changes, particularly during adolescence, pregnancy or the menstrual cycle.
• A diet rich in fats and sugars.
• Stress and anxiety.
• Use of aggressive cosmetics or those unsuitable for your skin type.
• Climatic conditions, such as humidity and heat.

What are the symptoms of excess sebum?

Excess sebum can manifest itself as :

• Shiny skin, especially on the T-zone (forehead, nose, chin).
• Visible, dilated pores.
• Blackheads, pimples and acne.
• Irregular skin texture.

How to regulate sebum production?

To regulate sebum production, we recommend :

• Use gentle cleansers adapted to oily skin.
• Apply light, non-comedogenic skin care products.
• Incorporate ingredients such as salicylic acid, glycolic acid and zinc into your skincare routine.
• Avoid alcohol-based products, which can dry out the skin and stimulate sebum production.
• Maintain a balanced, nutrient-rich diet.
• Manage stress through relaxation techniques such as yoga or meditation.

What products are recommended for oily, acne-prone skin?

For oily, acne-prone skin, it's crucial to choose products specifically formulated to control sebum production and prevent breakouts. Here are a few recommendations:

• Gentle, purifying cleansers: Choose cleansers that remove excess sebum without drying out the skin.
• Sebum-regulating serums: Serums containing niacinamide or salicylic acid can help regulate sebum production and reduce blemishes.
• Light moisturizers: Opt for water- or gel-based, non-comedogenic moisturizers that won't weigh down the skin.
• Purifying masks: Clay masks can absorb excess sebum and deep-clean pores.

How to get rid of blackheads caused by excess sebum?

To get rid of blackheads, which are often the result of excess sebum and dead cells clogging pores, you can follow these tips:

• Regular exfoliation: Use chemical exfoliants based on salicylic acid or glycolic acid to dissolve dead cells and dislodge impurities.
• Deep cleansing: Use cleansing brushes or ultrasonic devices for deeper pore cleansing.
• Clay masks: Apply clay masks once or twice a week to absorb excess sebum.
• Topical treatments: Creams or gels containing benzoyl peroxide or retinol can help unclog pores and prevent the formation of new blackheads.

What's the difference between sebum and sweat?

Sebum and sweat are two different substances produced by the skin. Sebum is an oil produced by the sebaceous glands, while sweat is an aqueous liquid produced by the sweat glands. Sebum moisturizes and protects the skin, while sweat helps regulate body temperature and eliminate toxins.

How does sebum affect the scalp and hair?

Sebum is also produced by the sebaceous glands of the scalp. It plays an essential role in protecting and moisturizing hair. However, excessive sebum production can lead to an oily scalp, heavy hair and problems such as dandruff and seborrheic dermatitis. Conversely, a lack of sebum can make hair dry and brittle.

What are the differences between sebum and acne?

Sebum is a natural substance produced by the sebaceous glands to protect and moisturize the skin. Acne, on the other hand, is a skin condition that occurs when hair follicles become clogged with sebum, dead cells and bacteria. Excessive sebum production can contribute to the development of acne, but acne itself is the result of inflammation and infection of the clogged follicles.

What foods can influence sebum production?

Diet can have a significant impact on sebum production. Certain foods can stimulate the sebaceous glands and increase sebum production, including :

• Foods rich in saturated fats and refined sugars.
• Dairy products, especially those containing hormones.
• Processed foods rich in trans fats. To maintain balanced sebum production, we recommend eating a diet rich in fruits, vegetables, lean proteins and omega-3 fatty acids.

Can medical treatments help control sebum production?

Yes, several medical treatments can help control sebum production. Dermatologists may prescribe :

• Topical or oral retinoids to regulate sebum production and treat acne.
• Oral contraceptives to balance hormonal levels and reduce sebum production in women.
• Hormonal treatments such as spironolactone to block the effects of androgens on the sebaceous glands.
• Antibiotics to reduce the bacteria and inflammation associated with acne.

How does age affect sebum production?

Sebum production changes throughout life. During adolescence, the sebaceous glands are often hyperactive due to hormonal changes, which can lead to oily skin and acne. As we age, sebum production decreases, which can lead to drier skin and an increase in fine lines and wrinkles. It's important to adapt your skincare routine according to your age and your skin's specific needs to maintain a good hydrolipidic balance.
