Your skin is more than just the reflection looking back at you in the mirror. It is a workhorse that works around the clock acting as your body's first defense from the environment.
When your skin barrier is healthy, your skin is glowing, and radiant. When it's in distress you will start to see symptoms of skin conditions surfacing, like dryness, flakiness and possibly redness.
What Is The Skin Barrier?
As you all know, your skin is the largest organ in your body and has many key functions! It helps maintain body temperature and acts as the primary barrier between your body and the environment. It consists of three different layers: the stratum corneum (aka the epidermis), the dermis, and the hypodermis (aka subcutaneous fat) at the deepest layer. If you’ve ever heard of a burn being third-degree for example, that is referring to the specific layer of skin that is impacted. The stratum corneum, the outermost layer of your skin, is the most crucial part of the skin barrier. It comprised of cholesterol, fatty acids (sebum), and ceramides which consist of lipids and make up over 50% of the skin's function that forms this natural barrier. Your skin’s outer layer is also referred to as the acid mantle. This acid mantle is your body's invisible force-field that keeps moisture in and pathogens out. It's formed from the combination of sebum and amino acids from your sweat to create a perfect pH of 5.5 that is neither too acidic nor too alkaline. You will notice the signs that your skin’s pH balance is off by visible damage to your skin such as dryness, flakiness, early signs of aging, redness, or more than usual sensitivity that normally occurs.
Symptoms of a compromised skin barrier:
- Acne
- Itchiness
- Dry, scaly skin
- Skin infections
- Sensitive or inflamed areas
- Rough or discolored patches
Some common skin conditions like eczema, an itchy skin condition that can be impacted by genes, food allergies, stress, and in some cases, using the wrong skincare products.
