Relationship Between Bricks And Mortar On The Skin And Exfoliation?
How is the relationship between the bricks and mortar model on the skin and the exfoliation?
Hello Macaroni, thank you for the question for HealthReplies.com
Human skin consists of 3 layers, the epidermis layer (outermost layer), the dermis layer (under the epidermis), and the subcutaneous layer (under the dermis). The epidermis layer of the skin is further divided into 5 layers which from the outside to the inside consist of:
and stratum basale
The brick and mortar model is only a histological analogy of the outermost layer of skin (the stratum corneum in the epidermis of the skin). This model analizes corneocyte cells (cells in the outer layer which are dead cells) as bricks and the lipid matrix as the mortar that connects these corneocytes.
Normally, the skin is always peeling. Exfoliation will always occur in the stratum corneum of the skin. At the same time, the stratum basale (which is the layer that has cells that are always dividing) will always produce new cells in the lower layer and the old cells will move upward to replace the cells in the layer above. Later the topmost cell will become the stratum corneum and experience peeling back. This will continue to happen throughout human life.
The lipid matrix (which is analogous to a mortar) is a matrix that will bind the corneocyte cells so they don't peel too quickly. This lipid matrix also has several other functions, among others, to maintain skin hydration, make the skin look soft and supple, prevent a lot of fluid from coming out of the inner layer of skin, protect the inner layer of skin from chemicals or pollutants that damage the skin. Several conditions can cause damage to this lipid matrix so that the skin can look dry and cracked, for example using soap that is too harsh, using ingredients that cause allergies or irritation to the skin, using too hot water to shower, rubbing too hard in the shower , and so forth.
So many answers from me, hopefully it will explain enough
