THE IMPORTANCE OF THE SKIN BARRIER AND HOW TO STRENGTHEN IT
What is the skin barrier?
The complex structure of the skin barrier consists of ceramides and other lipids that are essential for maintaining its barrier function. This barrier layer protects the skin from excessive moisture loss and protects it from the penetration of harmful substances and microorganisms. It works together with the hydrolipidic film to optimally protect the skin and maintain its functions.
Why is the skin barrier important?
An intact skin barrier protects against environmental influences, allergens and pathogens. Studies have shown that the skin barrier is crucial for general skin health. The role of the skin microbiome in maintaining the skin barrier function is increasingly recognized as important. A disrupted skin barrier can lead to skin problems such as dryness, irritation and infection.
Factors that damage the skin barrier
Various factors can impair the skin barrier. The most common causes include
- Excessive cleaning and aggressive cleaning agents
- Environmental factors such as UV radiation and pollution
- Lack of moisture supply
- Unbalanced diet
- Lack of sleep
- Hormonal changes
Repairing the skin barrier
If the skin barrier is impaired, it is important to use products that soothe and repair the skin. Ingredients such as panthenol, ceramides and pre- and postbiotics are particularly suitable for this. The importance of the skin microbiome in wound healing and restoring the skin barrier is also strongly emphasized in scientific articles.
Our Better Balm Ceramide Lip Care contains these important ingredients and is suitable for repairing the damaged skin barrier of the lips. Thanks to the combination of ceramides, panthenol and pre- and postbiotics, Better Balm Lip Care offers an effective solution for soothing and regenerating dry, chapped lips.

STRUCTURE OF THE SKIN AND ITS PROTECTIVE FUNCTIONS
The skin is the largest organ of the body and consists of three main layers: Epidermis, Dermis and Subcutis. Each of these skin layers has specific tasks and functions that are crucial for the health and well-being of the skin.
The three skin layers
1. epidermis
The epidermis is the outer layer of the skin and forms the primary protective barrier. It consists of several layers of cells that form a waterproof layer. The epidermis protects against mechanical damage, chemical substances and microorganisms.
2. dermis
The dermis lies beneath the epidermis and contains collagen and elastin fibers that give the skin firmness and elasticity. It supplies the epidermis with nutrients and is responsible for thermoregulation.
3. subcutis
The subcutis consists of fatty tissue that acts as a shock absorber and stores energy. It protects the internal organs and helps to store heat.
Functions of the skin
The skin has several important functions:
- Protective barrier of the body: Protects against external influences and pathogens.
- Temperature regulation: Helps to regulate body temperature through sweating and blood circulation.
- Sensory organ: perception of touch, pain and temperature.
PROTECTIVE SHIELD SKIN BARRIER
The skin forms a protective barrier that protects the body from harmful environmental influences such as toxic substances, UV radiation and pathogens. As the body's first line of defense, the health and function of this barrier is essential for the protection of the entire organism.
1. microbial barrier
The microbial barrier consists of certain microorganisms such as bacteria, fungi and yeasts. These "good" microorganisms, also known as commensals, prevent the growth of harmful microbes by competing for space and nutrients. A loss of these microbes can cause inflammation, chronic wounds or abscesses. In addition, the "good" microorganisms produce antibiotic substances that are effective against pathogens such as Staphylococcus aureus.
2. physical barrier
The physical barrier is formed by keratinocytes, which work together like bricks in a wall. These cells are held together by lipids (including sphingolipids), which act as mortar. The physical barrier protects against external influences and enables rapid regeneration and wound healing in the case of superficial injuries. The skin barrier is particularly vulnerable in atopic dermatitis, which underlines the importance of a robust physical barrier.
3. chemical barrier
The chemical barrier maintains an acidic environment of the skin, which prevents colonization by pathogens. Fat-splitting enzymes produce free fatty acids that nourish "good" bacteria and fight "bad" bacteria.
4. immunological barrier
The immunological barrier is based on the complex interactions of immune cells. Langerhans cells in the stratum spinosum alert the immune system upon contact with pathogens and contribute to the defense against pathogens.
HOW CAN THE SKIN BARRIER BE STRENGTHENED?
As the skin barrier is the body's first line of defense against environmental influences and skin diseases, it is important to keep it intact and resilient. Effective and gentle skin care plays a key role in maintaining and strengthening the skin barrier. To strengthen the skin barrier, it is crucial to use the right skincare products that are specifically designed to repair and build up the skin barrier.
Here are four skincare tips to support the skin barrier and improve its functions:
1. skin lipids support
Skin lipids play a central role in the skin's barrier function. Care products containing ceramides are particularly recommended. Ceramides, a subgroup of sphingolipids, are the skin's own lipids that can help to repair the damaged skin barrier and rebuild the skin barrier.
2. Use pH-neutral skin care products
The chemical skin barrier is based on a slightly acidic pH value of the skin, which is between 4.5 and 5.5. When purchasing cosmetic products, attention should therefore be paid to the pH value in order to preserve the skin's natural acid mantle. Gentle cleansing products with a skin-neutral pH value help to maintain the skin's protective barrier. Our The Ten out of Ten Gentle Gel Cleanser with mild sugar surfactants cleanses effectively without damaging the skin barrier.
3. avoid aggressive, abrasive exfoliants
Avoid highly abrasive, mechanical exfoliants that can damage the skin barrier by reducing skin lipids and possibly causing micro-injuries. A gentle alternative is chemical peels that can be used once or twice a week, depending on skin type and acid concentration, such as Active Acids Exfoliating Solution.
4. observe the skin and respond to individual needs
A regular skincare routine tailored to the skin type is crucial to strengthen the skin barrier. Soothing ingredients such as ceramides, panthenol (provitamin B5), amino acids and copper peptides can help to soothe the skin and improve the barrier function.
KEY TAKEAWAYS
A strong and healthy skin barrier is essential for protecting the skin and preventing skin problems. A disturbed skin barrier can lead to dryness, irritation and infections. It is therefore important to strengthen the skin barrier and build up the skin's protective barrier. Targeted care and the use of suitable products can strengthen the skin barrier and maintain it in the long term. The use of care products with ceramides can help to repair a damaged skin barrier and rebuild the skin barrier. Good sun protection is also essential to protect the skin barrier from UV damage. Proper care strengthens the skin structure and the body's protective barrier. Incorporating gentle cleansing products, moisturizing care and good sun protection into your daily skincare routine will contribute significantly to the health of your skin.
FAQ
The skin consists of three main layers: Epidermis, dermis and subcutis. Each of these layers contains different cell types and structures that fulfill specific functions.
The skin has numerous functions, including protection from external influences, regulation of body temperature and perception of touch and pain.
The skin is divided into three main layers: the epidermis, the dermis and the subcutis. The epidermis contains keratinocytes and melanocytes, the dermis contains collagen and elastic fibers as well as blood vessels, and the subcutis consists mainly of fatty tissue.
The epidermis protects the body from environmental influences, prevents water loss and contains cells that provide an immunological defense against microorganisms. It is also involved in the production of melanin, which protects the skin from UV rays.
Don't forget: Retinoids such as high-dose retinol and retinal make the skin more susceptible to sun damage such as sunburns, hyperpigmentation and signs of ageing. Therefore: Always apply sun protection (at least SPF 30, preferably SPF 50) when using Retinal - even in fall and winter.
A person has three main layers of skin: the epidermis, the dermis and the subcutis. The epidermis also consists of five sub-layers: Stratum corneum, stratum lucidum (only in certain areas), stratum granulosum, stratum spinosum and stratum basale.
The lower layer of the epidermis, the stratum basaleis responsible for the production of new skin cells. These cells migrate upwards to replace dead cells on the surface.
The skin acts as a barrier against physical, chemical and microbiological influences, regulates the water balance and body temperature and enables sensory perceptions. It also plays a role in immune defense.
The skin renews itself approximately every 28 days. However, this process, known as natural cell turnover, can be influenced by various factors such as age, diet and skin care. Regular exfoliation can help to remove dead skin cells and support the skin's renewal process.
The skin consists of three main layers: Epidermis (epidermis), dermis (dermis) and subcutis (hypodermis). The epidermis itself consists of several sub-layers.
