The Ultimate Guide to Understanding Your Skin Barrier
August 21, 2023
What is the Skin Barrier?
Our skin is the largest organ of the human body (and the most exposed, too) which means it needs to be well protected. Our skin barrier is the first line of defense against environmental stressors and irritants. It also protects against the loss of one of the most important things in the human body: water. The skin barrier owes its incredible defense to its selectively permeable nature - meaning a healthy skin barrier will keep the good things in and bad things out. For example, it will keep enough water in to allow it to function, and allows enough water out to hydrate the outermost layer of the skin. This keeps our skin flexible and soft.

How to Support and Maintain Your Skin Barrier
You can maintain your skin barrier through a skincare regimen that both respects and supports the key parts of the skin barrier. To avoid stripping your skin of those essential lipids and NMFs, gentle cleansing is key.When using products that exfoliate or encourage skin renewal, such as direct acids or retinoids, you should gradually add them into your skincare routine to avoid over-exfoliation and damage to the skin barrier. Lastly, to support your skin’s natural components, moisturizing ingredients will help to replenish your barrier, and prevent water-loss.
