What is the Skin Barrier, and Why is it Important?<\/strong>
The skin barrier is a critical function of the skin, taking the form of the ultra-thin, uppermost layer of the skin called the Stratum corneum <\/em>(SC). It functions as a physical barrier to keep harmful things, like pollutants and toxins, and microorganisms and viruses, from entering our bodies, and prevents good things, most importantly water, from leaving. Therefore, a well-functioning barrier is not only critical to the health of our skin but also to our general health.

What Does a Damaged Skin Barrier Look Like?<\/strong>
Early signs of barrier damage are dull looking skin<\/a>, followed by visible white lines, flaking skin, and mild erythema (redness). These visible changes are often accompanied by itching and tight feeling skin. Advanced barrier damage can result in cracking or even bleeding, painful skin. If these symptoms sound similar to those of dry skin that is no coincidence because barrier damage is the essential underlying cause of dry skin<\/a>.<\/p>\n\n\n\n

What Other Skin Conditions Can Be Caused by a Damaged Barrier?<\/strong><\/p>\n\n\n\n

Because the barrier protects the skin from irritant chemicals and microorganisms, a damaged barrier can quickly lead to irritated, inflamed skin. The condition of the skin barrier and skin irritation are intimately related because skin irritation also negatively affects the barrier function, which can cause a vicious cycle wherein the barrier damage causes irritation, which causes more barrier damage, causing more irritation, etc.<\/p>\n\n\n\n

A damaged barrier can also lead to breakouts as shed skin flakes can clog up pores, which is a critical step in the formation of pimples and blemishes.<\/p>\n\n\n\n


How to Restore Skin Barrier: 4 Effective Steps<\/strong>
There are four critical parts to repairing a compromised barrier, all of which should be combined in a well-designed skincare regimen or moisturizer:<\/p>\n\n\n\n

    \n
  1. Hydrate<\/strong>

    The ironic aspect of the skin barrier is that while its function is to limit water loss from the skin, water is also essential to the functioning of the barrier. Therefore,     hydrating the skin<\/a> is an essential step to barrier recovery. Although most skin products contain water, those water molecules are not absorbed by the skin but tend to evaporate within seconds of applying the product. Rather, hydration is achieved by using ingredients called humectants<\/em>. Humectants like Glycerin<\/a> and Hyaluronic Acid<\/a>, once absorbed by the skin, have the ability to attract water molecules from the atmospheres and hold on to them to minimize further water loss.

  2. Occlude<\/strong>

    Occlusives are molecules that are able to form a layer on top of the skin that effectively seals in moisture by preventing water from evaporating. It\u2019s like a temporary barrier on top of your real barrier that takes over its duties and gives it a chance to heal. Traditional occlusives like Petrolatum and Mineral Oil are used less and less because of their greasy skin feel and environmental concerns. They also tend to clog up pores making them unsuitable for acne prone skin. Modern alternatives like Squalane, plant-based Esters and Silicones provide a superior balance between performance, skin aesthetics, and environmental profile, while being suitable for a wide range of skin types.

  3. Replenish<\/strong>

    Lipids are a type of molecule that are an essential part of the skin barrier. They tend to have long \u201ctails\u201d that like oil and a smaller \u201chead\u201d that prefers to be closer to water molecules. This special property allows them to organize in layers that \u201cseal in\u201d the water molecules in the Stratum Corneum to maintain hydration and keep the barrier functional. Skin barrier lipids include     Ceramides<\/a>, Cholesterol, and Fatty Acids. Your skin produces these molecules naturally, but that ability slows down as we age, which is one of the reasons why the skin barrier function declines. Harsh cleansers in skincare and household products can also strip away the lipids from your skin and cause damage to the barrier. Luckily, lipids can be incorporated into moisturizers to replenish lost lipids to maintain\/restore barrier function.

  4. Soothe<\/strong>

    Regardless of whether skin irritation is the underlying cause or a consequence of barrier damage (it can be both), soothing irritated skin is an important part of preventing or strengthening the barrier, particularly if you have sensitive skin. You can find proven soothing agents in many products, including Colloidal Oatmeal, Panthenol (Vitamin B5),     Niacinamide<\/a> (Vitamin B3), and Bisabolol.<\/li>\n<\/ol>\n\n\n\n
