What is your skin made of?

The skin is made up of three layers: the epidermis, dermis and subcutaneous tissue. It also contains glands, hair follicles and nerve endings.
The epidermis, the outermost layer of skin, is made up mostly of dead cells that form a protective barrier against bacteria and other environmental threats. The dermis lies underneath the epidermis and contains nerves, sweat glands and hair follicles. This layer also provides strength to the skin by forming collagen fibers, which help keep its shape. Deeper still is the subcutaneous tissue which serves as insulation for our bodies by providing warmth in cold temperatures and helping us regulate body temperature when it gets too hot. ItÂ’s also responsible for storing fat to provide energy in times of need.

The skin plays an important role in protecting our bodies from infection due to its waterproof barrier around all external surfaces. It prevents water loss from internal organs while keeping out dirt, dust and other potentially harmful elements like bacteria or fungi from entering into our system through cuts or openings on the surface of our skin. Additionally, sebaceous glands located within this barrier secrete oil onto our skins surface which helps create a protective film that keeps moisture inside while repelling unwanted particles outside – further protecting us from potential harm caused by external factors.

Due to nerve endings found throughout all layers of the skin we are able to sense touch (pressure), heat/cold sensations as well as pain when something is amiss with this organ system – alerting us so we can take appropriate action before any further damage occurs.. Skin can also be affected cosmetically such as scars resulting after injury or acne due to clogged pores; these issues can eventually be resolved with proper hygiene practices and treatments available over-the-counter or prescribed medications depending on severity levels reached if needed at all
