Product Information

Acts as a protective barrier: The epidermis keeps bacteria and germs from entering your body and bloodstream and causing infections. It also protects against rain, sun and other elements. Keratinocytes are the major cells, constituting 95% of the epidermis, [11] while Merkel cells, melanocytes and Langerhans cells are also present. The epidermis can be further subdivided into the following strata or layers (beginning with the outermost layer): [12]

The dermis provides tensile strength and elasticity to the skin through an extracellular matrix composed of collagen fibrils, microfibrils, and elastic fibers, embedded in hyaluronan and proteoglycans. [13] Skin proteoglycans are varied and have very specific locations. [15] For example, hyaluronan, versican and decorin are present throughout the dermis and epidermis extracellular matrix, whereas biglycan and perlecan are only found in the epidermis. Sensation: contains a variety of nerve endings that react to heat and cold, touch, pressure, vibration, and tissue injury; see somatosensory system and haptics. Oxyhemoglobin: It is also found in blood and is not a pigment of the skin. It develops a red colour.

Keeps you in touch: Nerves in the dermis tell you when something is too hot to touch, itchy or super soft. These nerve receptors also help you feel pain.Water resistance: The skin acts as a water-resistant barrier so essential nutrients are not washed out of the body. [35] The human skin is the outer covering of the body and is the largest organ of the integumentary system. The skin has up to seven layers of ectodermal tissue guarding muscles, bones, ligaments and internal organs. Human skin is similar to most of the other mammals' skin, and it is very similar to pig skin. Though nearly all human skin is covered with hair follicles, it can appear hairless. There are two general types of skin, hairy and glabrous skin (hairless). The adjective cutaneous literally means "of the skin" (from Latin cutis, skin). The epidermis and dermis are separated by a thin sheet of fibers called the basement membrane, which is made through the action of both tissues.

Control of evaporation: the skin provides a relatively dry and semi-impermeable barrier to fluid loss. [35] Loss of this function contributes to the massive fluid loss in burns. Many animals store fat and water in the tissues of their skin. This allows these material to act as extra insulation while they are sitting around, waiting to be used. a b c Lee JW, Ratnakumar K, Hung KF, Rokunohe D, Kawasumi M (May 2020).

Damage from mechanical stressors was believed to be the only way to increase its permeability. [52] The skin patch is usually pink in color but can have a brown, tan, or gray base. This patch may appear the same color as the surrounding skin in people with darker skin.
