The skin is the largest organ in the body, accounting for around 16% of our total body weight. It is made up of three principle layers (epidermis, dermis, subcutaneous), each of which has various sub layers.
Our skin consists of three main layers - epidermis, dermis, subcutaneous - each of which has various sub-layers. The epidermis is the outer layer of constantly regenerating cells that gradually keratinize and flake off as they move from the innermost layer to the outermost. Under this, we have the dermis - a complex layer of elastic (elastin) and inelastic (collagen) connective tissue, oil, scent and sweat glands, hair follicles, blood vessels, and nerve fibers all 'cemented' together with a hyaluronic acid gel. Then finally the subcutaneous is a fatty tissue with connective fibers, larger blood vessels and nerve fibers.
The epidermis is the outer layer of the skin. Its thickness varies from 0.05mm (eyelids) to 1.5mm (soles/palms) depending on where it is found on the body. It consists of five layers who's principle functions are moisture retention and protection against disease and various external agents. The epidermis is in a constant state of renewal as the lowest cell layer divides and pushes upwards and the outermost layers transform into flat, keratinized cells and flake off. In healthy skin the epidermis is renewed every 15-30 days.
The dermis is found directly below the epidermis and also varies in thickness from 0.3mm (eyelid) to 3mm (back). Three principle types of tissue can be found in the dermis (reticular, elastic and collagen) as well as hair follicles, sebaceous glands (oil), apoerine glands (scent), eccrine glands (sweat), blood vessels and nerve fibers.
The subcutaneous tissue is a layer of fat and connective tissue found directly below the dermis. This tissue also varies in thickness depending on where it is found on the body and from person to person. It houses larger blood vessels and nerve fibers and plays an important role in body temperature regulation.
In summary, our skin consists of an outer layer of constantly regenerating cells that gradually keratinize and flake off as they move from the innermost layer to the outermost. Under this, we have a complex layer of elastic and inelastic connective tissue, oil, scent and sweat glands, hair follicles, blood vessels, and nerve fibers all 'cemented' together with a hyaluronic acid gel. Then finally we have a fatty tissue with connective fibers, larger blood vessels and nerve fibers during a week, then use once at night. Keep to a diet. Protect your skin from the sun.
During our life we only use 1/3 of our full organism's biological potential - it means that we could be still look and feel young in our 70s. Read full article: Skin Aging
As we get older some, or all, of our skin's components 'slow down', losing their ability to regenerate, while simultaneously suffering damage by free radicals and external factors such as pollution and ultraviolet rays. 'Aged' skin becomes wrinkled, saggy, dry, rough and chapped. These changes in the skin's structure and appearance are principally the result of:
- changes in hormone production
- a thinning of the epidermis
- a thinning of the subcutaneous fat
- a reduction in the water-binding capacity of the connective tissue
- a degeneration and reduction in mass of the connective tissue
In order to neutralize these ageing processes we need to help the skin by providing it with those components it lacks. It is important to consider here that our skin does not simply change overnight from 'young' skin to 'old' skin. These processes occur over time so we must be aware of what components our skin needs at each stage of our lives (see Plazan Diamond Series Creams). For optimum skin health we need the following components:
- hormones for improved cell activity and regeneration
- nutritive supplements to energize cells and optimize capacity
- hydrating and moisture-retaining components to bind, protect and tone skin tissue
- proteins and amino acids to serve as 'building blocks' for cell renewal
Finally, it must be also considered the quality of the components Plazan use in skin treatment and care. The best and most effective skin care cosmeceuticals are those based on placental cell extracts, not plant or animal sources. Placental cells are 100% compatible with those components found naturally in skin cells so are readily accepted into the biosynthesis processes. Plant extracts are not as readily accepted by our bodies and may create a dependency, requiring an increasing amount of active ingredients to maintain the skin's health as time goes by.
