The skin is the body’s largest organ, covering the entire outside of your body and weighing approximately six pounds. In addition to providing protection against heat, light, injury, and infection, the skin also regulates body temperature and stores water, fat, and vitamin D.
It’s truly amazing, so we thought we would take some time to explore this fascinating organ.
Throughout the body, the skin’s characteristics vary (i.e. thickness, color, texture). For instance, the skin on your head has more hair follicles than anywhere else, while the soles of your feet have none. The soles, along with the palms of your hands have much thicker layers than are found anywhere else on your body.
Your skin is made three layers – epidermis, dermis, and subcutis – and we thought we’d take some time to enumerate, further, the functions of each layer.
The epidermis is the thin outermost layer of your skin. It is, itself, made up of three layers. The stratum corneum is the one that is continuously shedding. The keratin, a protein formed from the dead cells, protects the skin from external substances. The keratinoctye layer has living squamous cells, which enable the skin to protect the rest of your body. And lastly, the innermost basal layer contains basal cells. These cells are continuously dividing to form new keratinocytes, replacing those that are being shed from your skin’s surface. Note: the epidermis also contains melanocytes, which are the pigment cells that produce melanin.
The next layer is the dermis. This middle layer is made up of blood vessels, lymph vessels, hair follicles, and sweat glands. The dermis is held together by a protein called collagen, made by fibroblasts – skin cells which give your skin its strength and resilience. This layer also contains pain and touch receptors.
Finally, the subcutis is the deepest layer of your skin – also known as the subcutaneous layer. The subcutis consists of a network of collagen and fat cells. These work to conserve your body’s heat and protects your body’s other organs from injury by acting as a shock absorber.
SKIN All Natural recognizes every aspect of your skin’s depth, and we strive to combine ingredients that are completely safe for each layer. Avoiding synthetics is the only way to protect your skin from lasting damage. This is the belief upon which our brand is built.
