What is Dermis?
Dermis is the second or middle layer of human skin. It contains collagen and elastin fibers, which are important proteins. Collagen and elastin in this layer of leather form a resistant layer similar to a net. The dermis also contains fibroblasts that are cells important for overall skin health, small blood vessels called capillaries and lymph nodes. Dearmis also contains sebaceous glands, hair follicles, sweat glands and nerves.
people do not see a dermis because it is under the epidermis, the upper layer of the skin and hiding from the glance. However, the fact that Dermis is hidden from sight does not mean that it is less important. This layer of skin is thicker than the farthest layer and has a job that gives the skin its columns and strength. It also helps the body to maintain its temperature and even sends nutrients to a part of the epidermis. Because Dermis contains nerves, it also helps one recognize a number of feelings, including pain, ear and heat or cold.
differentNot parts of this skin layer have important tasks. For example, collagen and elastin proteins help the skin to be durable and steep, but at the same time firm. Fibroblasts in this skin layer play an important role in both synthesis of collagen and elastin. In fact, this type of cell helps synthesize other molecules that also support the structure of the skin. Small blood vessels that are present in this layer of skin help to nourish and provide the necessary oxygen, while lymph nodes help protect the skin from microorganisms.
Thesebaceous glands in the dermis also have an important job. It serves to produce oily substances called cuddling, which helps lubricate not only the skin but also the hair that stands out. The substance also helps to make the skin somewhat water. Sweed glands are also important as they help the body regulate its temperature. In fact, some people call sweat that sweat glands produce air conditioning for the body; Its presence on the skin surface helps the body cool.
Interesting JE that people often try to use creams against wrinkles on the surface of their skin and the results are disappointed. This is due to the fact that wrinkles develop in the dermis and most of the creams cannot penetrate that far into the skin. It is therefore unlikely that collagen creams that are often sold for the repair or prevention of wrinkles will be effective.
