Skin Barrier Function is a common phrase in skincare circles, but just what is it?
Using the brick-and-mortar model is the best way to demonstrate the optimal structure of our skin.
Like a brick wall composed of bricks held together with mortar, in our skin, the bricks are flattened skin cells called corneocytes, and the mortar holding them in place is a highly organized lipid structure of waxy compounds, oils, and fats.
The skin barrier is fundamentally an organized structure composed of highly complex lipid compounds: ceramides, cholesterol, and fatty acids.
Maintaining this protective lipid structure will help improve hydration, calm inflammation and sensitivity, slow aging, and prevent pigmentation, all of which flow from the ability to maintain the lipid layers intact and functioning.
These are a few oils that can help maintain its lipid organization and help it repair and revitalize itself:
Oils can help activate the skin to protect the body from stress, inflammation, and damage.
These are:
- Pomegranate seed oil
- Sea buckthorn fruit oil
- Black seed oil
- Argan oil
- Olive oil
Oils rich in omega-3 fatty acids
- Perilla seed oil
- Sacha inchi
- Chia seed oil
- Fig seed oil
Also, by applying carotenoid-rich oils, we can minimize the damage oxygen can cause, allowing the skin barrier to do its job of repairing and revitalizing the tissues.
For carotenoids, look for the colors deep yellow, orange, and red.
- Buriti oil
- Sea buckthorn seed or fruit oils
- Rose hip seed oil
- Tucuma oil
By working with oils that naturally supply these fatty acids and plant compounds, you help the skin maintain the organization of its lipid layers allowing the barrier to do its job.
