Case Study: Dermabrasion
While beauty is only skin deep, those who have troubled complexion resulting from acne, aging, or injury may find their skin improved through dermabrasion. This cosmetic procedure is done by a skilled physician who removes unwanted skin. In the case of Mrs. Jones, a 48 year old homemaker, a successful dermabrasion treatment was conducted. There wasn’t severe pain or bleeding of the skin, which indicates that the right layer and a sufficient amount of skin was removed. The removed dead skin layer would soon be regenerated by the underlying facial epidermis, which will give rise to new cells called keratonocytes. Mrs. Jones will soon notice a difference in the complexion and texture of her skin, due to the new underlying layer that will take over the old damages layer. The thought of removing a layer of the skin sounds terrifying and possibly harmful, but there are many people that undergo this unique procedure in order to achieve better looking skin. Now that you know that there is a treatment that can remove unwanted layers of the skin, you may be wondering what layers are there, and what layer is removed?
The skin is made of three layers of tissues. The epidermis is the superficial layer, dermis is the underlying layer that is well supplied with blood vessels, and the hypodermis is the deepest layer that has more areolar and adipose tissue. The epidermis layer of the skin is avascular, and it is the layer that the physician removes during a dermabrasion procedure. This layer is made of five zones known as startas. The stratum basal is the deepest layer that contains stem cells, which give rise to keratonocytes. These karatinocytes are pushed upward, forming the upper layer called the stratum spinosum. The stratum granulosum has three to five layers of flat cells. The layer that is seen in only thick skin such as; the palms, and the soles of the feet is called stratum lucidum. The layer that sits on the top is called stratum corneum that consists of up to 30 layers of dead scaly skin. This layer is especially resistant to water loss. All of these layers work together to create a protective layer of epidermis. Each one has a unique function, but there is one specific layer out of all of these that gives rise to the cells that form the overall epidermis.
The stratum basal layer of the skin divides mitotically to form the epidermis cell layer. The stem cells divide to form keratinocytes that migrate toward the skin surface and replace lost epidermal cells.
