The skin is a complex organ made up of layers that all crucially contribute to skin health. The outermost layer, the epidermis, is what is seen with the naked eye and functions as a waterproof, protective barrier. Ceramides are widely accepted as the foundational blocks that allow for these protective barrier functions to occur.
What are Ceramides?
Ceramides are lipids that naturally occur in the epidermal layer of the skin and link with other lipids and fatty acids to form our skin’s barrier. Ceramides alone make up about 50% of the epidermis. The body produces ceramides organically, but similarly to collagen and elastin, these levels naturally decrease due to age and environmental factors.
Insufficient ceramides within the skin will encourage trans-epidermal water loss which leads the skin to struggle with water retention. This water loss can accentuate fine lines and the skin will become dry and rough. Skin barrier damage may also lead to an influx of acne and irritation.
