Know Your Skin And Skin Related Problems

Skin problems are something that bother a lot of people during their lifetime. But most commonly it tends to trouble people during their younger days, especially during adolescents, it can become a huge problem for many people. And then it tends to persist throughout their life as young adults. And only later in life does the problem actually settle down. But the reason skin diseases are so distressing for people is because it affects one of the most important phases in their lives, that time of their life when they can look their best. And having this time spoilt by skin related problems is a definite no no. and this is why most people prefer to obtain good knowledge about their skin and how it functions so that they can take better care of it.

What you must know is that current modern forms of therapy, such as microdermabrasion machines all target only the visible, outer and superficial layer of the skin. But the skin has more to it than that. Because the skin consist of three layers, the outermost and visible layer called the epidermis, the dermis which lies underneath that and the subcutis, which is the thin layer of fat that we have under our skin. So if you want to avoid skin problems all together, then you have to make sure that all three layers remain healthy. Because most of the problems that appear on the surface epidermal layer, is actually originating from the inner layers.

And the modern machines like the professional laser hair removal machine treat skin by penetrating into these inner layers. Because the dermis is of mesodermal origin and is a matrix of collagen and elastin fibers, surrounded by an extracellular gel-like substance (ground substance). These fibers give skin its strength and elasticity. The dermis contains a range of cells: fibroblasts, mast cells, lymphocytes and dermal dendritic cells. It also contains blood and lymphatic vessels, nerves, muscle and appendages (sebaceous glands, sweat glands and hair follicles). In the upper papillary dermis, there are finger-like projections that contain terminal capillary networks. The lower reticular dermis is thicker and denser.

Eccrine sweat glands are found throughout the skin, except at the mucosal surfaces, and are responsible for most thermoregulatory sweating. Apocrine sweat glands are found in the axillae and anogenital area, and do not function until puberty. Sebaceous glands are also inactive until puberty, when they excrete an oily substance called sebum under the influence of androgens. Sebum passes on to the skin surface via the pilosebaceous duct (hair follicle). Its lipids contribute to the skin barrier and have antimicrobial actions. Sebaceous glands are found in the highest density on the face, scalp and upper torso. The skin is richly innervated. Sensory nerve fibers transmit stimuli of touch, pain, itch, vibration, pressure and temperature. Innervation of dermal autonomic structures, including sweat glands, blood vessels and arrectores pilorum muscles, control the skin’s thermoregulatory mechanisms.
