Skin Moisture Barrier
What It Does and How You Can Help Take Care of It?
What is the moisture barrier?
An outer layer of skin called the moisture barrier holds and traps water to keep your skin moisturized. Water escaping your barrier and evaporating into the air around you is known as transepidermal water loss, and it is one of the ways your skin dries out. Therefore, maintaining a robust moisture layer is crucial for proper skin function.
What then constitutes this moisture barrier?
A mixture of lipids and proteins from skin cells that have died. If there was any area of the skin that resembled the brick wall from the brick-and-mortar comparison I made in the opening, it would be this. .Squalene and ceramides are examples of the natural oils and waxes that make up your skin's lipid layer. The proteins are things like collagen and keratin (see, I told you it wasn't an entirely incorrect image!) If you want to get technical, the outermost layer of the epidermis is known as the stratum corneum and is what protects the skin from moisture.
How does it relate to the skin barrier?
We must comprehend the skin barrier in its entirety in order to contextualize this moisture barrier (or stratum corneum; I'll refer to them both as such from this point forward). It's not just this physical barrier, as we formerly believed. The skin barrier is made up of four primary parts, according to Bowe. It also includes elements including the skin's immune system, acid mantle, and microbiome.
Let's break it down:
The outermost layer of the skin, known as the stratum corneum or moisture barrier, is composed of lipids and proteins. This is the layer that maintains moisture.
The many bacteria that live on and in our skin make up the skin microbiome. The health of the skin and body as a whole is profoundly influenced by the skin microbiome, despite its inherent complexity.
The thin, somewhat acidic membrane that covers the skin is known as the acid mantle. It is a combination of your perspiration and natural sebum (oil). Your body's and face's skin's pH range varies between 4.7 and 5.751.
All of the foregoing, as well as skin-resident immune cells and free radical scavengers (such antioxidants), are included in the skin's immune system (yes, the skin has its own immune system).
Together, these components enhance and support one another. For instance, the skin microbiome can assist in the production of postbiotics, or byproducts, such lipids and peptides that feed back into the stratum corneum. On the other hand, if one is weak, it can hurt the others. For instance, if the acid mantle is disturbed, the biome's microbiota may shift or the lipids that make up the moisture barrier may be removed.
How does it become damaged?
The moisture barrier may be impacted by a variety of factors, including those that are beyond of your control. If your barrier becomes easily irritated, inflamed, burns, or reacts to things that it used to tolerate, this is a sign that it has become compromised or weakened. The major elements to be careful of when maintaining the moisture barrier are listed below.
- Hot water and harsh soaps
Sulfates and powerful soaps strip the skin of its oils and harm the proteins, which causes a large portion of the damage to the moisture barrier. The lubricating oils on the skin can also be dissolved by hot water.
- Over exfoliation
The removal of dead skin cells from the stratum corneum is referred to as exfoliation. To some extent, doing this is beneficial because it can promote cell turnover and make the skin appear more vivid, but when you go too far, you risk destroying the priceless lipids and proteins that make up the skin's outer layer.
- Lifestyle habits
The dermal density of the skin has been found to be impacted by internal dehydration. Internal dehydration can also be caused by factors like drinking drying beverages (caffeine, alcohol). Finally, the barrier can be harmed by things like smoking.
- Sun exposure and pollution
Free radicals and oxidative stress from environmental stimuli are constantly present on the skin.
- Skipping hydrating topical
It will harm the barrier and cause transepidermal water loss if you forget to face cream or body lotion after showering or washing.
FAQ's about skin moisture barrier
1. What is a moisture barrier?
A moisture barrier, also known as a skin barrier or skin moisture barrier, refers to the outermost layer of the skin that acts as a protective barrier against external factors such as moisture loss, irritants, and environmental pollutants. It helps to maintain the skin's hydration levels and overall health.
2. Why is a moisture barrier important?
A healthy moisture barrier is crucial for maintaining optimal skin health. It helps to retain moisture within the skin, preventing dryness and dehydration. A strong moisture barrier also acts as a defense mechanism, protecting the skin from harmful bacteria, allergens, and irritants. When the moisture barrier is compromised, it can lead to various skin issues such as dryness, sensitivity, inflammation, and increased vulnerability to skin conditions.
3. How can I tell if my moisture barrier is damaged?
Signs of a damaged moisture barrier may include dryness, tightness, redness, flakiness, itching, and increased sensitivity. You may also notice a dull complexion or an increase in skin sensitivity to certain products. Additionally, if your skin feels easily irritated or experiences frequent breakouts, it could be an indication of a compromised moisture barrier.
4. How can I repair and strengthen my moisture barrier?
To repair and strengthen your moisture barrier, it's important to adopt a skincare routine that focuses on hydration and protection. This includes using gentle cleansers, avoiding harsh ingredients, incorporating moisturizers with hydrating ingredients like hyaluronic acid and ceramides, and applying sunscreen daily. Additionally, using products specifically formulated to support the moisture barrier, such as barrier creams or serums, can aid in its repair and maintenance.
It's worth noting that if you're experiencing persistent or severe skin issues related to your moisture barrier, it's recommended to consult with a dermatologist for a proper diagnosis and personalized treatment plan.
