To understand the skin barrier's function, we need to know how the skin is structured. You may have heard that the skin is made up of three distinct layers, but that's only partially correct. The skin has three main layers (epidermis, dermis, and hypodermis), each with several sublayers, most of which serve their specialized functions. However, for this article, let's focus on the top-level epidermis. 

The outermost part of the epidermis is the stratum corneum or the skin's protective barrier. Scientists often liken the structure of the stratum corneum to a brick wall. In this analogy, skin cells are the building blocks. Everything else, including the skin barrier, is the mortar that holds it all together. This grout contains essential nutrients such as cholesterol, ceramides, and fatty acids. Together, these compounds are known as the skin's "Natural moisturizers" because they help moisturize and nourish the deeper layers of the skin.

What Are The Main Skin Barrier Functions?

The skin barrier has several roles, many of which are health-related. Among all the functions of the skin barrier, researchers generally agree that the skin barrier has three main roles, it protects the body from external stressors such as pollution and UV rays, retains moisture to hydrate the body and skin, and delivers vital nutrients to the skin. Words to keep the various systems of the body in balance.

The skin barrier is also the most important factor that determines the appearance of healthy skin. A strong skin barrier can effectively retain moisture, keeping the skin hydrated, smooth, and elastic. Skin problems such as irritation are less likely to occur.  

What Can Cause a Weak Skin Barrier?

It is nearly impossible to list all potential causes of skin barrier damage. Everything from genetic makeup to lifestyle can affect skin barrier health. The most important factors that can impair barrier function include chronic exposure to ultraviolet light, smoking, and pollution. Physical damage, such as excessive exfoliation, can also affect skin barrier health, as can lifestyle factors such as stress levels and sleep duration. Think of it like this, any internal or external stressor that causes visible skin changes can disrupt or damage the skin barrier. Avoiding these stressors can help protect the skin barrier and contribute to a healthy appearance.
