Wat is huidbarrière?

Simpel gezegd is de huidbarrière een waterdichte afsluiting die de buitenste lagen van de huid bij elkaar houdt. Bij een gezonde huidbarrière voelt je huid glad en zacht aan, maar als deze buitenste lagen beschadigd zijn, kan de huid er dof uitzien en ruw of droog aanvoelen.

What is the stratum corneum made of?

The stratum corneum consists of a series of layers of specialized skin cells that are continuously shedding. It’s also called the horny layer, as the cells are tougher than most, like an animal’s horn. The stratum corneum exists to protect the inner layers of skin. Most areas of the stratum corneum are about 20 layers of cells thick.

How thick is the stratum corneum in reptiles?

Generally, the stratum corneum is made up of 15-20 dead cell layers with a thickness of 10-40 micrometer. The stratum corneum is permanent in reptiles and is only replaced during the phase of rapid growth called molting or ecdysis. Beta-keratin is also present and provides rigidity to the skin layer.

How do you see the stratum corneum?

The stratum corneum can be visualized by examining sectioned epidermal tissue under hematoxylin and eosin staining under light microscopy. The corneocytes present in the stratum corneum are flat, eosinophilic cells that lack nuclei. The stratum compactum and stratum disjunctum layers can generally be visualized easily.

What products can damage the stratum corneum?

Unfortunately, some of the products that you use to clean your body can harm the stratum corneum. Surfactants, such as hand soap, will bind to the proteins in the skin and allow water loss through the skin and weaken the barrier created. Using sensitive soap, such as an unscented bar soap, and not over-washing is suggested.
