You become one year older as each year passes by, you cannot change that reality. But your appearance need not have to be an indicator of your age. You might have admired many movie stars and celebrities on how they look so young at such an old age. One of the main factors that make you appear young is your skin.
Your beauty starts with your skin. Maintaining a beautiful skin is not a rocket science. All you need to have to achieve it is little care from your side.
There are many more benefits that our skin offers apart from making us look good. A good skin care would pave the foundation for better health as well.
The biggest part of our body is skin. It stretches for nearly 2 square meters in size. It constitutes three layers, which is epidermis, dermis, and fat. The outer most layer which is epidermis is more rigid. Cells present in epidermis layer is called as keratinocytes. There is a junction that is present in-between epidermis and dermis. One of the regions of epidermis layer is termed as basal layer. It is in this layer does the growth of new cells occurs. As the growth of these cells progresses they reach the epidermis layer and gradually start to die and wither away as dead cells. Once the cells start to die, it paves way for the growth of new cells. This happens in cycles of 28 to 40 days time period.
Epidermis
Epidermis layer acts as a sort of protection. It also acts as a water proof. Additionally, it protects us from bacteria, viruses from entering the body. This layer also prevents damage to the internal organs at times of injury.
The basal region contains melanocytes. Melanocytes is responsible for the release of melanin. It filters ultra violet radiations. It helps to protect us from skin cancer. Additionally, it prevents any damage to the DNA. Melanin is the main reason for sun tan when we are exposed to warm light.
Langerhans is another type of cell which you can find inside epidermis. It helps with protecting us from diseases. When it detects any bacterial infection in the skin, it stops the bacteria from penetrating further and flushes it out.
Dermis
Next layer of our skin is called dermis. It is made up of many threads like structures. It is these threads that offer strength to our skin. Collagen and Elastin tissues are present in this layer. Nerve endings are also present in this layer. Sensations are like touch, pain, warmth, cold, and pressure are felt only through these nerve endings.
Sweat glands are present in this layer. It helps to maintain our body temperature. We start to sweat when there is an increase in body temperature. When the released sweat starts to vaporize our body begins to cool down.
Sebaceous glands which secrete sebum is also present in this layer. These glands are attached to hair follicles. It helps to keep the skin soft and hydrated. Dermis also contains hair follicles. Hair follicles are responsible for beauty, controlling body’s temperature, and offering protection from injuries.
Next, comes the arteries. Arteries provide us with nutrients and maintain body’s temperature.
Fat
The bottom most layer is the fat. The fat layer is also responsible for maintaining our body’s temperature. It acts like a cushion. Additionally, it helps with storing energy.
So, we should learn not only to appreciate the external beauty of the skin but also learn to appreciate its complex working mechanism and take more care to protect it.
