The skin on the face is more delicate and it requires care
The skin of the face is more slender and contains a higher centralization of skin oil organs when contrasted with the skin of whatever is left of the body. This is the reason acne tends to be on the face so regularly. In any case, skin oil organs on the body, especially the back, have a tendency to be bigger, which is the reason when skin break out injuries happen on the body, they have a tendency to be bigger in the estimate.
The skin on the face is thinner and delicate, this is why when it comes to treating acne it needs to be a gentler treatment regimen, then a more aggressive treatment regimen when it comes to the skin on the body because it is thicker.
The skin on the face and body differ in two key areas:
1. Skin care: taking care of your facial skin differs from your body skin. While you handle the former gently you handle the later more aggressively.
2. Anatomy: the skin consists of the epidermis, dermis, and hypodermis, and in these three layers lays the difference between the skin on the face and the one on the body.
We are going to take a look at how the layers of the skin differ from the one on the face and the one on the body.
The epidermis is the external layer of the skin, in charge of counteracting passage of outside substances into the skin and in addition keeping water loss from the skin.
It is additionally partitioned into a few sublayers, which incorporate the stratum basale and the stratum corneum. These sub-layers are made out of various kinds of cells.
The innermost layer of the epidermis is the stratum basale. Different cells in the stratum basale contribute to the skin’s color, sense of touch, and protective effects:
- Merkel cells, another name for these cells are tactile cells. These cells are modified nerve endings and are the cells that are responsible for touch detection.
- Melanocytes these cells produce pigments known as melanin. This pigment give rise to hair and skin color these pigments called melanin also provide protection for the rays present in the sun called ultraviolet rays.
- Keratinocytes this make up 90% of the cells in the epiderm. In the stratum basale, they experience repeated cell division to shape new cells that ceaselessly supplant more seasoned cells. As old keratinocytes are supplanted, they travel through the upper layers of the epidermis toward the skin’s surface, where they experience auxiliary and substance changes that change them into cells called corneocytes.
- Langerhans these are the cells that form part of the immune system of the skin. They help detect the presence of foreign substance and protect the body against infection. These cells are also the ones responsible for skin allergies.
The stratum corneum which is the topmost layer of the epidermis is waterproof. This feature allows it to viruses, bacteria and other unwanted substance from getting into the body.
The most important component of the stratum corneum is the Corneocytes. In order for these cells to adhere to one another, they acquire structures called desmosomes this structure helps in the prevention of water loss. They also contain protein. As this corneocytes mature, they get tougher and create the protective outer layer of the skin.
After the epidermis comes to the dermis. This is the part of the skin that is responsible for the skin elasticity and skin strength. This is where the sweat gland, blood vessels, hair follicles, sebaceous (oil) glands and nerve endings are located.
- Sweating gland: the sweat gland is divided into two major types namely: Apocrine gland and Eccrine glands. The former grows in areas that contain a large number of hairs some of which are the groins and the armpit. They produce a substance that is milky, and this substance gives odor whenever they come in contact with the bacteria on the body. On the other hand, the later is not in contact with hair follicles. This makes them produce clean sweat that aid in the controlling of the temperature of the body as it leaves the skin.
- Sebaceous glands: These glands are usually joined to the follicles. They produce sebum (oily substance) which is responsible for lubrication and serves as waterproof for the skin. These glands also provide protection against antibacterial.
- Blood vessels: this is the part of the dermise that provides nutrient to the epidermis. Due to the lack of blood vessels in the epidermis, it depends on the dermise for the provision of its nourishment. These vessels which are in the dermis are also important when it comes to regulation of temperature. This is one of the most important functions of the skin. When the temperature is high, it enlarges the blood vessels and the gives rise to the increase in blood flow to the skin surface to the area where the heat is being released and vice versa
- Hair follicles: these are the ones responsible for the production of hair that serves as a body temperature regulator and at the same time they enhance sensation. The hairs on the body can be divided into two type: terminal hair and vellus hair. The vellus hair contains light pigments, they are soft and fine. These hairs are mostly found in children but when they grow to become adults, these hairs are replaced by a terminal hair. Terminal hair: These ones are coarser, they are longer and also dark in color compared to the vellus hair. When a person gets to the pubertal stage, this hair grows on the genital area of both females and males, and also for the men they grow on the chest, feet’s and arms.
This is the third and innermost layer of the skin. This layer comprises of cells that serve as an insulator for the skin and also protects it from cold and heat. This fatty tissue in the hypodermis is called an Adipose. This tissues stores energy in the body during the time of lack of calories and also produces protective paddings.
Comparison between the hypodermis on the face and the one on the body
The distribution of the adipose tissues is affected by genetic factors. Also, environmental factors that include exercise and diet also determine how thick the skin will be. Generally, you find thicker hypodermis in the buttocks of females, thighs, and hips. While in both genders the one on the cheeks is the thickest. When calories are consumed in quantum, it increases the number of adipocytes and also aids in the generation of new ones. For the short term, overheating contributes to the size of the adipocytes in lean persons. While in obese person overheating does not only increase the size but also Increase the quantity of the adipocytes.
