Ceramides are one of three types of lipids (fats) along with cholesterol and free fatty acids found in the stratum corneum, the top layer of the epidermis, the skin’s covering. These three lipids have many different functions in the body. In addition to helping to maintain the skin’s protective barrier, ceramides also function as cell signaling agents.
There are nine different types of ceramides in the stratum corneum, named ceramide 1 to ceramide 9 and they make up between 40-50% of the lipids in the stratum corneum. Studies have shown that individuals with dry skin conditions such as eczema have significantly fewer ceramides in their stratum corneum. Interestingly, individuals with psoriasis have been found to have normal numbers of ceramides, but fewer of some types and more of others.
Ceramides Can Improve Eczema
We know that lipids in the stratum corneum can be replaced with topical preparations. Best results are achieved when lipids are applied in certain ratios to restore the skin’s barrier function. The use of ceramides in the treatment of eczema has demonstrated good results.
If you have dry skin or eczema, you may want to consider a ceramide containing formulation. Here are two to consider:
- Impruv Barrier Repair Cream – This formulation contains ceramides plus other lipids to help strengthen the skin’s protective barrier.
- La Roche Posay Nutritic 2.5% or 5% – Natural biolipids mimic the skin’s ceramides to restore the skin’s barrier function.
