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, ormoisture 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 cracksthrough 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. (Wait… Your skin can be both oily AND dehydrated?
Some other damaged skin barrier symptoms:
- Flakiness & Peeling
- Rough to the touch
- Stinging or burning sensation when products are applied
- Crepiness and fine lines
- Rashes like eczema (atopic dermatitis)

When you read over this list of these symptoms, you might notice that a whole range of skin issues can be traced back to a damaged skin barrier. That’s why caring for your skin barrier is so important.
