The skin is the largest organ in the human body.

The skin is made up of 3 main layers and the skin's barrier, also known as the acid mantle, which protects the skin against bacteria, viruses, pollution and dehydration. This acid mantle is composed of the stratum corneum and the hydrolipid film. Where the stratum corneum protects the dermis layer of skin from trans epidermal water loss and external factors, the hydrolipid film is the key to the skin's protective barrier. This film is a thin, oily acidic layer mainly made of sweat, water, sebum, and other lipids. Should this layer get damaged, the acid mantle is broken, and the skin barrier becomes vulnerable to infections, dryness, dehydration, inflammation, and irritation.

What is the microbiome and why is it important?

The skin microbiome is a diverse community of bacteria, fungi, viruses, and other microorganisms that naturally live on the surface of the skin. Some of these microorganisms help protect the body by preventing harmful pathogens from growing, supporting the immune system, and maintaining the skin's natural barrier. A healthy, balanced skin microbiome is essential for keeping skin healthy, while disruptions to this balance can lead to an increase in harmful microorganisms and contribute to conditions such as acne, eczema, and skin infections.

  • Natural Protection

    For natural skin protection balance is crucial. A slightly acidic pH balance of pH5.5 supports the healthy balance between "good" & "bad" microorganisms. A healthy balance of the skin's microbiome protects the skin from harmful microorganisms and environmental influences.

  • External Factors

    The influence of various internal and external factors can disturb the balance, such as inadequate skincare, improper nutrition, mental stress and environmental influences, such as pollution and sun damage.

  • Irritation & Infection

    If many harmful influences combine, the skin microbiome loses its balance. If the skin microbiome is unbalanced, the protective acid mantle is disturbed. This means the risk of irritations, infections and allergies increases.

What could damage your skin barrier?

There are many influences that could cause damage to the skin’s barrier, resulting in reduced defence against harmful microorganisms, viruses and allergens. If the skin barrier is damaged, it can lead to a variety of skin conditions and increase the risk of infections.

  • Close up of washing hands with soap

    Using Traditional Soaps & Skincare

    Cleaning your body with standard soaps or skincare products can strip away the skin’s natural oils and disrupt the skin’s pH balance.

  • Close up of skin in the sun with water droplets

    Environmental factors

    Cold weather, pollution, overexposure to the sun, and other external stresses can weaken the skin’s natural protective barrier, leading to dryness, sensitivity and discomfort.

  • A woman looking stressed.

    Psychological or biological factors

    Stress, anxiety and hormonal changes, including those experienced during menopause, can affect the skin’s barrier function and its ability to maintain moisture and protection.

    Aging

    As we age, our skin naturally becomes thinner and loses its ability to produce as much oil as it used to.

  • Some medication in a person's hand

    Medical Conditions & Treatments

    Certain medical conditions and treatments can affect the skin’s health, appearance and sensitivity, such as diabetes and chemotherapy.

  • A hot water tap

    Hot water

    Bathing and showering in overly hot water can strip away the skin’s natural oils and disrupt the skin’s pH balance

How do I care for my skin correctly?

Skin cleansing is an essential part of daily care. It helps remove dirt, sweat, sebum, dead skin cells, microorganisms and their potentially irritating by-products, leaving skin feeling clean and refreshed. However, it is important to maintain the skin’s delicate balance, as over-cleansing or using unsuitable products can disrupt the barrier and lead to dryness, irritation, increased sensitivity and a greater susceptibility to skin problems.

The rule is:

Do not cleanse your skin too often, too long, too hot or with aggressive products. Soap-free skin cleansing with a pH of 5.5 with the sebamed products not only protects the skin's barrier function against drying out and irritation, it also maintains the balance of the healthy skin microbiome.

The skin's protective layer requires regular care.

Skin care adjusted to skin type and the skin's individual and current needs support the natural protective functions, compensates for fat and moisture deficits, neutralises harmful environmental influences and helps maintain the microbiome balance. For all of this, a pH of 5.5 has been proven to be important, as shown in many scientific studies.

  • Someone dipping their hand in a bubbly bath

    Washing & Bathing

    Do not wash, shower or bathe too often, too long too hot or with aggressive products.

  • An Air conditioning unit

    Heating & Air-con

    Dry air from heating and air-conditioning stresses the skin's protective layer - support it with pH5.5.

  • close up of a face getting a skin peel treatment

    Skin Peels

    Peelings make the skin smooth, but weaken the skin's protective layer - do not use too often and apply intensive care and protection afterwards.
