The Science of Ceramides: what are those?

Understanding ceramides

Ceramides, wax-like lipid molecules, belong to a group of lipids or fats that make up two main components of our skin's cell membranes. Naturally present in the human skin, their levels decrease with age, essentially halting production by the age of 40 (1).

Why ceramides matter?

Ceramides are essential for maintaining healthy skin of all genders and skin types and are beneficial for everyone, regardless of skin concerns. Ceramides play an important role in strengthening the skin barrier, preventing moisture loss and protecting against environmental aggressors (2).  Using ceramide-enriched skin care products is essential to combat dryness, flakiness, and maintain a supple complexion.

Especially in the cold embrace of the winter, our skin faces significant decrease in ceramides level, as depicted in the graph illustrating seasonal effects on ceramide levels in human skin. Ceramides, vital lipid molecules for skin health, serve as the skin's natural protectors, forming a protective barrier against harsh weather conditions. In winter, this protective shield weakens, making the skin more sensitive to dryness and external stress factors.

The importance of the ratio of occlusive ingredients to skin lipids

Pay attention to the occlusive ingredients in the moisturizer - especially if you have dry skin or it shows signs of aging - for example, natural occlusive ingredients like lanolin, or synthetic ones like petrolatum and dimethicone, as well as possible microplastics (like acrylates). If they are combined with ceramides in a product, it is important to check that the 3:1:1 ratio of skin lipids to ceramides, free fatty acids and cholesterol is maintained. Without this balance, the product might lead to a disrupted skin barrier, potentially causing increased dependency on these products and exacerbating skin problems over time (4).

 

What are the benefits of ceramides for the skin barrier?

  • Moisture Retention: Prevents moisture loss, keeping skin hydrated, smooth and supple.
  • Protective layer: forms a barrier that protects the skin from dehydration and environmental damage.
  • Anti-aging: Promotes anti-aging by keeping skin moist and supple (3).
