Trans epidermal Water Loss – What is it and How to Stop It
If you are struggling with dehydrated or dry skin, one of the causes may be trans epidermal water loss (TEWL). You're losing water and moisture from your skin. TEWL can lead to a variety of dry skin conditions — including severe dehydration — but there are ways that you can keep your skin hydrated or prevent dryness from occurring in the first place. What Is Trans epidermal Water Loss? To understand TEWL, let's revisit the layers of our skin. Our skin is made up of three primary layers, the outermost being the epidermis (aka what you look at in the mirror). The dermis is the middle layer, and the hypodermis is the innermost layer. TEWL occurs when water passes from the dermis through the epidermis and evaporates through the skin barrier.

Skin Barrier Issues.
Your skin barrier is the lipid matrix found in the outermost layer of your skin, the stratum-corneum, and essentially sits on top of this layer. When healthy, the skin barrier helps keep moisture in and external irritants out (e.g., UV, free radicals, bacteria) - acting as your skin’s bodyguard.What is the skin barrier?The skin barrier, or moisture barrier, is mainly composed of three lipids: ceramides, cholesterol, and free (AKA essential) fatty acids. These lipids work together to prevent water loss and to protect your skin from the environment. Damage to the skin barrier occurs in the form of miniscule cracks through which moisture can easily escape and irritants can enter more easily.Signs your skin barrier is damaged:When your skin barrier is healthy, your skin generally looks plump and smooth and feels soft to the touch. If you have oily skin that’s also dehydrated, that’s a common sign that you may have a damaged skin barrier. (Yes ... Your skin can be both oily and dehydrated.
