Skin is a natural and first line of defense against the harsh external environment such as toxins, allergens, chemicals, and infectious agents. Internally, it prevents water loss and maintains hemostasis.

The skin or epidermal barrier is the outermost layer of the epidermis called stratum corneum. It is made up of corneocytes (dead cells) and lipid matrix containing free fatty acids, cholesterols, ceramide, and moisture. The skin barrier is like a brick wall in which corneocytes are the bricks and the lipid matrix is the mortar.

Tight junctions and anti-microbial peptides also contribute to maintaining the skin barrier. Tight junctions seal the space between the cells and don’t allow any material to pass through it. So, ions or molecules have to enter the cell to get absorbed in the skin. Also, they are bidirectional means they act as a barrier on both sides.

Antimicrobial peptides are expressed abundantly in the skin and contribute to maintaining the skin barrier. These peptides are produced in the deeper layer of the epidermis and then transported to the outer layer, stratum corneum. They act as the first line of defense against the potential organisms trying to enter the skin barrier.

As you grow old, the lipid matrix on your skin barrier begins to decline, as a result, tiny openings develop in your skin which let the free radicals and irritants to enter the body. Also, there will be excessive water loss from these tiny openings which let the skin dry and tight. This process enhances in winter due to the dryer air and loss of moisture. If you have ever noticed your skin becomes dry, red, inflamed, or pigmented then you might have a compromised skin barrier.

Skin barrier protects our skin in the following ways:

Stops the infectious agents like bacteria, viruses, and fungi from entering the skin.
Act as a shield against environmental stress like ultraviolent radiations, cold and hot temperatures.
Contribute to the Innate immunity of the person.
Act as a semi-permeable barrier that allows only some of the topically applied substances to pass and blocks others.
Retains moisture by preventing water loss.
It helps to maintain the normal temperature of the body.
