Skin is the biggest organ in the body. And it is one of the most important organs as it shields all other organs inside it. The skin forms the sense of touch and maintains the body temperature.
Skin also plays a major role in protecting the body against pathogens and also from excessive water loss. It also synthesise vitamin D and protects vitamin B folates.
Though we all know that skin is the largest organ, we just think it as an outer covering. Well, let’s see what makes the skin. Not every individual has the same skin; some may have dry skin or some others may have oily skin. Moreover, the colour of the skin also changes from one individual to another. Some may be dark or some may be fair or some may be white. Well, melanin is the substance that gives colour t the skin.
Coming to the skin, it has three layers — Epidermis, Dermis and Subcutaneous.
Epidermis is the outermost layer, the part that we see. It is here where the hairs and the sweat glands open. Just below the epidermis is the dermis, which consists of nerve endings, blood vessels, oil and sweat glands.
The last and the bottom layer is Subcutaneous. This layer has fats, which helps in keeping the body warm. Subcutaneous layer also acts as a shock absorber and it is here where the hair follicles emerge.
Well, proper skin care is needed or one is at a higher risk for pathogens.
