Building Strong Skin: Your Skin Barrier Simplified

in Jan 5, 2024

We all want healthy, radiant skin, but sometimes it feels like a mystery. Let's break it down into simple terms. Think of your skin as a wall, and we'll talk about the bricks and mortar that make it strong, how to keep it hydrated, and what can go wrong.

Your Skin Wall - Bricks and Cement: Imagine your skin is like a wall. The outer layer is the "brick" layer, called the stratum corneum. It's made up of corneocytes, like bricks in a wall, and they play a role in protecting your skin from the sun, bumps, and keeping it hydrated.

Now, the "cement" in this wall is the lipid matrix, which includes ceramides, fatty acids, and cholesterol. This cement protects your skin like a barrier, keeping out bad stuff and making sure your skin stays healthy.

Keeping Moisture In: To have happy skin, you need to keep it hydrated. Your skin has different levels of moisture, with the inner layer having lots (70% water) and the outer layer, the stratum corneum, having less (only 13%). How much moisture your skin has depends on a few things:

  1. The Weather: Think of your skin like a sponge. Dry air can make it lose water, while humid air helps it stay moist.

  2. Skin Oils: The oils in your skin, like the cement in our wall, keep moisture in. If these oils get damaged, your skin can get dry.

  3. Acid Mantle: Your skin has a protective layer, like an invisible shield called the acid mantle. It helps keep the right balance for your skin to stay moist.

Nature's Moisture Helper: Your skin has a natural way of keeping itself hydrated. It's like a sponge that holds onto water using something called the Natural Moisturizing Factor (NMF). NMF is like a collection of tiny sponges made of things like amino acids, lactic acid, and glycerol. They're most concentrated in the lower part of the stratum corneum, where they trap moisture and keep your skin happy.

When Things Go Wrong: Sometimes, things can mess up the skin barrier. If the acid mantle, the brick-like corneocytes, or the lipid cement get damaged, your skin can lose water, leading to dry, itchy, and uncomfortable skin. This can result in skin conditions like eczema, psoriasis, redness or very dry skin.


Moisture's Best Friends - Humectants: Now, let's talk about moisture helpers - humectants. Think of them as magnets for water. They can pull moisture from the air and take it deep into your skin. Some common ones are Hyaluronic acid, Glycerine, and Polyglutamic Acid. They help keep your skin hydrated.

Here are some for you to try! 

Ceramides (part of the skin's lipid barrier):

  • Banilla Co Cleansing Balm
  • Apothaka Barrier Repair Serum
  • Apothaka AOX Serum

Conclusion: Achieving healthy, hydrated skin is like building a strong wall. Protect your skin's acid mantle, take care of the brick and cement, and use moisture magnets like humectants. When you understand these basics, you're on your way to having happy, glowing skin. Skincare is a bit like a science, but with simple steps, you can unlock the secret to your skin's natural beauty.
