What Is The Epidermis?
The epidermis is the outermost of the three layers that make up the skin. It contains various kinds of cells that offer protection and assist in the visual appearance of the skin.
Functions Of The Epidermis
The epidermis is exposed to the outside elements and creates a barrier against the deeper layers of your skin and the external factors. Its most important function is protecting the body from UV radiations, harmful chemicals and intrusion of bacteria and other microbes into the skin.
In recent years, it has been discovered that the epidermis has a complex functionality in the skin’s immunity system and defense mechanisms.
Within the epidermis’ various layers, here’s what each one offers to the skin:
- Production of melanin: the innermost layer of the epidermis, stratum basale, is home to melanocytes, the melanin-producing cells. When exposed to sunlight, the melanocytes produce more melanin to protect the skin against UV radiations
- Producing new cells: the innermost layer also contains the basal cells. These cells continuously divide and are pushed to the outer layers of the skin to replace the older cells that eventually shed off
- Prevent infiltration: 95% of the cells in the epidermis are the keratinocytes, according to science. These cells act as a barrier against foreign substances infiltrating the skin. In addition to preventing toxins from entering the skin, it also prevents loss of moisture, heat and other important constituents of the skin
- The Epidermal Barrier:the topmost layer of the epidermis, the stratum corneum (SC), serves the most important barrier functions of this layer. The SC is composed of brick-like structure that prevents the loss of moisture, microbes and other pathogens from entering the skin. In short, the health of this barrier determines the health of the skin
Symptoms Of Epidermal Barrier Damage
The barrier is, single-handedly, the most important aspect of having healthy, smooth skin. But the daily effect of pollution, stress and harsh products can take a toll on it. Here’s signs to prove that your epidermal barrier is damaged:
- Skin looks and feels dry: if your skin looks dry and flaky, it only means that your skin’s barrier is damaged. Barrier damage caused by moisture loss also results in the skin being depleted of essential oils, making it extremely sensitive and prone to inflammation
- Skin feels tight minutes after applying moisturizer: skin feels dry minutes after applying moisturizer because the layer that locks moisture in the skin has been damaged general moisturizers cannot repair it
- Stinging or burning on applying skincare: a sign that your skin is rejecting the products. Any harsh skincare will further cause damage to the skin barrier
- Red patches on the skin: a damaged barrier results in external particles entering the deeper layers of the skin. In such cases, the skin fights back by using healing properties and causing inflammation. This becomes a constant process, causing redness, and acne
Here's What You Can Do To Protect The Epidermis:
- Use a pH balancing cleanser to no disturb the balance in your skin’s mechanism
