The Barrier Function of the Skin: An Essential Concept

The skin’s barrier function is a fundamental aspect for the care and health of our skin. It is like the fortress that protects our body from external threats, and its importance lies in its ability to prevent the entry of pathogens and prevent various skin conditions.

This barrier function is made up of the outermost layer of the skin, known as the stratum corneum, which acts as a physical barrier. Its role is crucial to prevent the loss of water and electrolytes, keep the skin hydrated, and develop an immune defense that prevents the entry of microorganisms, bacteria and fungi.

When this function is compromised, the skin becomes dehydrated and becomes more prone to the entry of substances that can trigger unwanted skin reactions, such as irritations, allergies, or even infections.

The Composition and Functioning of the Barrier Function

From an anatomical point of view, the barrier function of the skin involves both the epidermis and the dermis. Functionally, it is divided into four groups: the microbiota, the chemical group, the physical group, and the immune group.

Each of these groups plays a crucial role in maintaining barrier function, and any alteration in any of them can lead to the appearance of allergies or dermatitis.

Maintenance and Care of the Barrier Function

To preserve the integrity of the barrier function, it is essential to use products that combine emollients and humectants, without compromising any of the levels necessary for their balance.

In addition, it is important to follow certain guidelines in daily skin care, such as opting for gentle cleansers that do not remove natural oils, using moisturizing creams with ingredients such as glycerin, hyaluronic acid and ceramides, protecting the skin from sun exposure, avoiding very hot water, and look for products with repairing ingredients such as ceramides, fatty acids and niacinamide.

Likewise, a diet rich in antioxidants, omega-3 fatty acids and vitamins can significantly contribute to maintaining healthy barrier function from within the body.

The Importance of Caring for the Barrier Function

Taking proper care of the barrier function not only helps prevent problems such as dryness and irritation, but also contributes to keeping the skin looking radiant and younger. Its alteration can lead to premature aging, so its care is essential for the health and appearance of the skin.

In summary, understanding the importance of the skin’s barrier function and how to keep it in balance is essential to ensure healthy and protected skin. By following the right recommendations, we can preserve this crucial function and enjoy beautiful, healthy skin over time.
