Our skin consists of three distinct layers. The hypodermis (more commonly known as the ‘subcutaneous tissue’), the dermis, and the epidermis. Out of the three layers, the epidermis happens to be the outermost layer of our skin, which protects our body from harmful substances like pollution or allergies.

But what is a skin barrier? Well, the outermost layer of the epidermis, referred to as ‘stratum corneum,’ is known as the ‘skin barrier.’ It’s like a protective sheet that prevents moisture from escaping the skin and also prevents allergies and viruses from penetrating the skin. Let’s explore this blog till the end to find out more about how to protect the skin barrier, and what things cause damage to it.

A Brief Overview of The Skin Barrier

First up, let’s explore the reason why it is called ‘skin barrier’ and not anything else!

Well, as mentioned above, it’s the outermost layer of the epidermis. That’s one reason. And the second reason is that, if looked at under a microscope, this outermost layer resembles that of a brick wall. The skin cells, or the ‘corneocytes’, are like bricks, which are held together by a lipid membrane consisting of ceramides, various fatty acids, and cholesterol, thereby justifying the name!

The skin barrier acts as the first line of defense against external elements like pollution, infections, toxins, UV rays, etc. Along with that, it also helps regulate temperature and prevent water loss, which further justifies its importance.

What Causes Damage to The Skin Barrier?

Several factors can contribute to a damaged skin barrier. Let’s take a look at them-

• Too much exposure to the sun.
• Various alkaline-based products that affect the skin’s pH levels.
• Various cosmetic products dry out the skin’s natural oil and moisture.
• A handful of skin conditions, like psoriasis, atopic dermatitis, or eczema.
• Pollutants and allergens.
• Dry temperatures with low humidity levels.
• Mental stress.
• Aging.
• Steroids.
• Any kind of trauma (cuts or burns).
• Over exfoliation.
• UV rays.

Excessive dryness, which results in flaking skin, an increase in infections and allergic reactions, and frequent inflammation, are warning signs that your skin barrier has suffered severe damage.

How To Repair Skin Barrier?

Now that you know the signs of a damaged skin barrier, let’s move on and look at some of the tips to repair skin barrier damage-

Avoid using harsh skincare products

The first and foremost step to restore the skin barrier is to stop using skincare products that contain harsh chemicals. The skin has a pH level of 4.7. So while buying any product, make sure that the pH levels range from 4 to 5 for the best results.

Try out plant-based oil to repair the damage

Plant-based oils are another set of natural moisturizers that assist in repairing the skin barrier. Products like jojoba oil, coconut oil, sunflower oil, almond oil, etc., contain antioxidants and anti-bacterial formulas that have positive effects on any skin type. This is one of the best solutions if you want to know how to protect skin barrier naturally.

Choose moisturizers that contain glycerin or hyaluronic acid

Dryness on the skin is a common sign of damage, for which moisturizers are a great solution. So, try to get moisturizers that contain glycerin or hyaluronic acid. These moisturizers effectively block almost 99% of water loss from the skin, thereby keeping it moist.
