At Desert Bloom Plastic Surgery, you’ve probably heard the term “skin barrier function” a time or two. Skin barrier function is important to correcting skin weakness, sensitivity, dryness, and restoring skin health. What is skin barrier function? According to Dr. Zein Obagi, the barrier function “acts as a protective skin envelope preventing penetration of harmful substances and excessive trans-epidermal water loss. It also enhances epidermal renewal repair, which is responsible for building and maintaining skin tolerance.” THe barrier function is made up of water, lipids, and proteins. Stratum corneum cells are arranged in multiple layers that are enveloped in water, lipids, and proteins. How do you repair skin barrier function? Correcting epidermal weakness and dryness by restoring water, lipid and protein balance, preventing trans-epidermal water loss and regulating natural skin exfoliation. This can be achieved through skincare products and treatments in which hydration is restored and the skin is being exfoliated. There are three steps to achieve this with skincare. First, prepare the skin’s surface through a good cleanser, toner, and exfoliant. Next, regulate natural exfoliation through an exfoliation accelerator. Finally, repair the skin’s barrier by repairing damaged DNA. Daily Power Defense is clinically proven to penetrate deep into the skin and repair DNA from the inside out. A healthy skin barrier is imperative to protect against harmful substances and excessive loss of moisture. Talk to your skincare professional about how you can treat a compromised skin barrier.
