Skin is defined as the thin layer of tissue forming the natural outer covering of the body of a person or animal. The skin is the largest organ on the human body and it makes up several different components including water, protein, lipids, and minerals and chemicals. On average the skin weighs about six pounds and its job is to protect the body from infections and germs. Over the span of a person’s lifetime, the skin will continuously regenerate every 27-30 days which is why maintaining health skin is essential and protecting this vital organ. The skin has layers; there the out layer of dead skin, the stratum corneum. The stratum corneum contains dead skin cells that used to exist in the epidermis. Using facial scrubs and some other skin products will remove or thin this layer. Next is the epidermis, the out layer of skin. It is the thinnest layer of the skin, but it is responsible for protecting the body from the harsh environment. The epidermis has four layers of its own: stratum germinativum, stratum spinosum, stratum granulosum, and stratum lucidum. The epidermis also hosts different types of cells: keratinocytes, melanocytes and Langerhans cells. Keratinocytes produce the protein known as keratin, the main component of the epidermis. Melanocytes produce your skin pigment, known as melanin. Langerhans cells prevent foreign substances from getting into the skin. Next is the dermis, the middle layer of skin. This is the layer responsible for wrinkles. The dermis is a complex combination of blood vessels, hair follicles, and sebaceous glands. Collagen and elastin, the two proteins necessary for support and elasticity within the skin, are synthesized here. This layer also contains nerves that sense pain, touch, and temperature. Finally, there’s the subcutis, the ski’s fatty layer. This layer hosts sweat glands, and fat and loose connective tissue. The subcutis is responsible for conserving the body's heat and protecting the vital inner organs. Cleaning the skin regularly with mild soaps helps it maintain its overall elasticity and promotes healthier regeneration. Moisturizing is also essential in skin health in that it makes it smooth and pliable to the touch, further promoting skin regeneration. Sunscreen is one of the most important elements in skin protection and skin health because it protects the sensitive cells within the skin from harmful UVA and UVB rays radiated by the sun. Protecting the cells within the skin is pertinent in that it protects against skin cancer, preemptive aging, liver spots, dark spots, and uneven skin tone.
