Broadly speaking, your skin consists of three layers:
- Epidermis: This is the skin barrier, also called stratum corneum, which is your skin’s first line of defense against free radicals.
- Dermis: The middle skin layer which is primarily made up by collagen and elastin to provide strength and flexibility to your skin. It’s also where hair follicles grow.
- Hypodermis: The deepest skin layer which is closest to the muscle with an important function to insulate the body and absorb shock and damage to internal organs.
The skin barrier is basically a system of cells and lipids that together form a shield on your skin — picture it like a brickwall. As illustrated above, the cells are like bricks in your skin barrier. But to keep them together (think mortar), you need lipids like ceramides, cholesterol and fatty acids — enter high performance skincare products with the right active ingredients at the effective levels.
When the skin barrier is at its best, your skin feels awesome. But if it’s damaged, free radicals can penetrate your skin and potentially cause harm to your body. Free radicals can be generated by an array of external aggressors, which can affect your skin barrier.
If you find yourself exposed to one or more aggressors, it’s even more important to make sure to boost and protect your skin barrier:
Aging
UV exposure
Over-exfoliating
Air pollution
Exercise & sweat
Harsh chemicals
Dry or humid climate
Emotional stress
Whether the skin barrier is broken or not, the key to happy and healthy skin comes with a simple routine with the rightactive ingredients in every product at the effective levels. This both rebuilds a damaged skin barrier and protects your skin barrier.
