Skin basics

  1. 1. Deep and Meaningful Pty Ltd P.O.Box 427 Ascot Vale Victoria, 3032 Australia ABN 33 080 145 795Skin Basics...Natural skin care treatments work to support the important functions of the skin.The skin is the largest organ of the body and like all organs of the body it has its own set duties to perform in orderto keep the body healthy and functioning correctly. Your skin works hard to protect you every day in manycomplex ways without you even knowing about it. Supporting your skin with the use of natural skin caretreatments provides vital nourishment and nutrients to assist the natural skin functioning that you are unable tosee in action in the deeper layers. The use of quality all natural skin care optimizes overall skin functioning andenhances your skins tone, texture and appearance. Both the body and the skin respond and connect with natureso it is not surprising to learn that natural skin care treatments and all natural skin care products are so readilyaccepted and absorbed by the skin and the body.Although our skin makes up the majority of our exterior appearance and holds all of our internal organs together itis much more complex than being the bone and muscle covering that we see on the outside. Let’s explore whatthis amazing organ actually does and how it functions in more detail.The skin is comprised of three main layers:EpidermisThe epidermis is the outer and visible portion of the skin and it is made up of five layers: • Stratum Corneum • Stratum Lucidum (only found on the palms and soles of the feet) • Stratum Granulosum • Stratum Spinosum • Stratum Germinativum/Basal layer- where cell division takes place.The skins surface has many tiny openings through which hairs appear and sweat is excreted. These tiny openingsextend down into the dermis and become our hair follicles and sweat ducts.DermisThe dermis is the middle layer of the skin and is made of connective tissues, collagen and elastin and contains mostof the nerve endings, blood vessels and lymphatic and immune systems of the skin. Our capillaries are housed hereto supply nutrients, water and oxygen to the epidermis.Oil and sweat glands are located in the dermis, along with hair follicles that receive nourishment to allow our hairsto grow and extend upwards, appearing through the tiny openings of the skins surface.Page 1 of 4 Copyright © D&M 2009

Deep and Meaningful Pty Ltd P.O.Box 427 Ascot Vale Victoria, 3032 Australia ABN 33 080 145 795The dermis also acts as a supporting framework and is responsible for the skins elasticity.Hypodermis/SubcutaneousKnown as the cushioning layer, this final layer of the skin contains our storage of adipose (‘fat’) tissue to act as ashock absorber.The hypodermis connects the skin with all the underlying muscle tissues.Throughout the layers of the skin there is a proliferation of nerves and receptors that respond to touch, pressureand pain, alerting us to pleasure as well as unpleasant stimuli. The skin is a very intricate structure that requiressupport. External care and a number of internal body functions are required to support the skins ability tomaintain its optimum condition.The skin provides the ultimate protection...Protection against microbial invasionThe skin as a whole intact organ prevents microbes (germs) from being able to enter the body. Microbes can landon the skin but cannot enter unless there is a break in it. The skin also has a continuous renewal of cells (mitosis)taking place and as new cells are formed, all the cells above them are forced upwards. Eventually the cells on thesurface of the skin slough off and any microbes attached to these skin cells are carried away too. The process ofmitosis (cell renewal) is continuous but it takes approximately 28 days for a newly developed cell to reach thesurface of the skin and approximately another 12 days for it to be sloughed away.The skin also secretes sebum onto its surface to maintain a slightly acidic environment, helping to inhibit microbiallife, provide a natural, protective barrier and maintain skin suppleness.Protection against chemicals and pollutantsHere again, an intact skin acts as a barrier against chemicals and pollutants. There is a certain amount ofabsorption that can take place through the skin but the quantity and rate of absorption is limited by the followingfactors: • The size and type of substance molecules in contact with the skin • The concentration of the substance • The length of exposure to the substancePage 2 of 4 Copyright © D&M 2009
  3. 3. Deep and Meaningful Pty Ltd P.O.Box 427 Ascot Vale Victoria, 3032 Australia ABN 33 080 145 795 • The area of skin on the body where this contact is madeThis absorption limitation provided by the skin, helps to protect the body against the entry of harmful chemicals.Exchange of gasesHave you ever heard it said that the skin can breathe? Well, it basically does – oxygen can enter and carbon dioxidecan escape- the exchanging of gases. Obviously this does not occur in great enough quantities to sustain lifewithout normal breathing, but it is still a necessity for health.Temperature controlThe body needs to maintain a fairly constant internal temperature in order to function properly. When the internalbody temperature increases, the blood vessels in the skin dilate (expand). This allows a larger amount of warmblood to flow through a larger area of the skin and closer to the surface, allowing heat to be radiated out of thebody. When this alone does not cool the body sufficiently, the body begins to sweat and as this moisture (now onthe skin surface) evaporates, it reduces the temperature in the body.When we are cold, our blood vessels constrict (narrow) reducing the surface area from which blood heat can belost to the outside environment. Storage of adipose (fatty) tissue also helps to aid as insulation against cold. Thehairs on our bodies are also a form of temperature control. When we are cold, we get goose bumps where ourhairs ‘stand on end’ in an attempt by the body to trap the radiating heat in and keep it close to the skin.Excretion of toxinsAs we sweat we excrete toxins that are contained in the skin, helping to maintain a healthier internal environment.Protection against internal damageThe hypodermis is made up of adipose (fatty) tissue which acts as a cushioning agent against damage from bumpsand knocks. The fatty tissue storage is also the body’s way of preventing death too quickly in times of famine. Itacts as an emergency energy supply that is held in storage until required.SecretionThe skin, as stated before, secretes sebum on to the surface of the skin. Apart from creating the acidicenvironment, the sebum creates a barrier on the surface of the skin. This barrier not only prevents outsideelements from entering, but prevents moisture loss from the skin itself, helping to keep the skin and the internalbody hydrated.Page 3 of 4 Copyright © D&M 2009

Deep and Meaningful Pty Ltd P.O.Box 427 Ascot Vale Victoria, 3032 Australia ABN 33 080 145 795ImmunityThe skin also plays an important role in our immunity- containing immune system cells that have the ability toisolate and destroy microbes and foreign particles that find a means of entrance into the skin.
