Skin is the largest organ in the body and covers body tissues. Wiki: Skin  It  plays a key role in protecting the body against pathogens, excessive water loss, excretes toxic wastes, has about 500,000 sweat glands and can produce more than a pint of sweat a day, regulates temperature, acts as an insulator, is sensitive to heat and cold, touch, pressure and vibration, absorbs oxygen and nitrogen, stores fat and water and produces fat-soluble vitamin D. Since the skin contains a lot of fat, it thereby also absorbs and stores many substances and dangerous chemicals that are also fat soluble. It acts as a monitoring system to protect you from harm.  Wiki: Skin

Although there is much that we know about the skin, there is also a lot that we do not know.  This disparity of knowledge about the skin …. how it works, the interpretation of the symptoms and causes, what it is made of and treatment modalities …. all contribute to much disagreement and controversy among the medical experts and general public about human skin. 

This article summarizes what is known about the skin and how we may maintain skin health.  New research discoveries shed a light on the three key ingredients of skin health. 

There is general agreement about the following: 

1. Skin is a barometer of the health of the rest of the body. When the skin functions properly it has aesthetically pleasing properties, giving skin a healthful appearance and feel and the body is healthy. On the other hand, a less attractive skin reflects unhealthy biological conditions. 

2. Skin ages and loses its elasticity and ability to regenerate.

3. Skin has the ability to heal itself and is virtually indestructible.

4. Skin has multiple functions.

5. Skin is an major detoxifier.

6. Skin damage can include: laxity, discoloration, wrinkling, thickening, changes in skin texture, abnormal skin growths, and impaired wound healing are also possible. 

7. Most commercial skin supplementations and creams and lotions do not work.

8. Skin aging is a normal process and is difficult to distinguish chronological age from other effects.

9. Cumulative effects of decades of skin wear cannot be reversed, although the effects on skin appearance may be temporarily masked.

10. Skin damage usually causes inflammation, discomfort and pain.   skin damage

11. Skin health is linked to large colon health.   Probiotics and a balanced diet may be important to balance the microbes in the large gut.

12. Skin can synthesize up to 10,000IU of vitamin D in half an hour or less of sun exposure on about 40 % of body. Skin prevents the disease rickets.

Symptoms of unhealthy skin and body: Dry skin, itchy skin, rashes, inflammation and pain are symptoms.  Interpreting the symptoms and how to relieve the symptoms is where there is disagreement and controversy. 

Abnormalities that appear on the skin are usually a sign of metabolic and other glandular disorders in the body.  Yilmaz: skin mirroors health 

The architecture of the skin can help us understand our skin.  The skin is composed of several different functioning and interdependent layers.

Illustration above shows the skin layers where the three most important ingredients for skin health are located:

Epidermis: This is the outer most skin layer and is about the thickness of a page.   There are nine different ceramides or fatty lipoids [ green color in illustration ] located mostly in the very top epidermis layer known as stratum corneum. The stratum corneum (SC) acts as a protective barrier, keeping moisture in and irritants and infection out. However, the SC is often compromised, allowing the skin to become very dry and itchy. Ceramides help protect collagen.  Collagen, yellow in the illustration, makes up 70 % of our skin and is found in stratum corneum and the dermis. It is the glue that holds tissues and cells together and acts as a skin filler, preventing wrinkles.  Hyaluronic acid [HA], blue in the illustration, is found in the epidermis and dermis and every cell in the body; although 50 % of all HA in the body is found in the skin.  HA absorbs water, preserves moisture in the skin and helps in healing the body. It also works with collagen and acts as a filler and cushions the skin. 

Dermis is about ten times thicker than the epidermis and contains the blood vessels that feed the skin, nerves, sebaceous glands, and hair follicles.

Hypodermis: The final 'fatty tissue' layer in the diagram, also referred to as the subcutaneous layer, contains sweat glands, some hair follicles, blood vessels and fat tissue. The hypodermis is used mainly for fat storage.

Maintaining healthy skin:  There are three ways to keep your skin healthy:

1.  by eating a whole food complex diet that provides the natural essential nutrients from within the body.

2. by covering the skin with a lotion/cream that has the ability to transport ceramides, hyaluronic acid and collagen to the skin without plugging up skin pores.  Most skin cream/lotions cannot do this. 

3. by taking nutritional supplements.  Eating a good diet may be difficult to do today and one may need to supplement with nutritional supplements. 

Which nutrients are essential for good skin health?  The best way to answer this question is to unravel the biochemistry of how ceramides, hyaluronic acid and collagen are synthesized by the body:

Ceramides:  are synthesized by the body from fatty lipid compounds, phosporus and amino acids [proteins]; help maintain the water retention in the stratum corneum and help regulate apoptasis or programmed cell death.  Failure to properly regulate apoptosis can have catastrophic consequences, Rivas: ceramides cause muscle loss 2012  and can result in many disease states including cancer, diabetes, neuropathies, Alzheimer's disease, Parkinson's disease, and atherosclerosis.  AOCS: Ceramides   Ceramides are naturally-occurring in many foods. Sphingoiipids, which contain Ceramides, are found in large amounts in dairy products, eggs and soybeans. Ceramides are also found in rice, millet, and spinach. Walker: plant derived ceramides

Collagen: is synthesized by the body from vitamin C, silica and elastin.  Skin deteriorates when collagen breaks down.  Silica is essential for maintaining the health of connective tissues due to its interaction with hyaluronic acid.  Collagen makes up more than 70 percent of our skin.  Ceramides help protect collagen.

Hyaluronic acid: Hyaluronic Acid is synthesized by the body from iron, zinc, magnesium, calcium, selenium, protein amino acids and vitamins A and C.  Vitamin D, iodine, chlorophyll, and silica should not be discounted! Sorochan: Hyaluronic acid 2014  The HA molecule acts like a cellular sponge. Manasa: Review HA 2012    Brown: HA skin absortion 1999   Collagen gives the skin its firmness but it is HA that nourishes and hydrates the collagen. HA acts as a space-filler in dermal layers between skin cells on a long term basis; enhancing soft, smooth and elastic skin.  Sorochan: Hyaluronic acid 2014

Hyaluronic Acid [HA] has dual functions: excess amount causes inflammation when repairing injury while lesser amounts suppress inflammation after healing.  There is no direct research to support claims that food contains hyaluronic acid; except for trace amounts in meat.  Hyaluronic Acid (HA) is not in the diet in any appreciable amounts. Manasa: Review HA 2012   However, there is a link between HA, magnesium, zinc, vitamins A and C and diseases and health.  Sorochan: Hyaluronic acid 2014  Liguori Double-blind study HA 1997

Nutrients for healthy skin:  Most of the skin health comes from nutrients: Minerals magnesium, copper, selenium, zinc, iron and phosphorus; silica; Vitamins A, B5, C, E, D, K2, niacin; Amino Acids methionine, cysteine, praline and glycine; Arachidonic acid [fat], Linoleic acid (LA), essential fatty acids (EFA); and essential factors that cannot be synthesized by humans that include omega-6 fatty acid, alpha-linolenic acid (ALA), and omega-3 fatty acid. Fallon Weston Price: skin nutrition 2010  Morell: Nutrition for skin 2010  Vesper: ceramides in food 2002  Kresser: skin nutrition  Michaels: nutrition & skin health 2011  Ongoing research has linked bacteria in the large intestine or colon with skin health and disorders. Such bacteria are often referred to as probiotics. 

Probiotics: The inner lying of the large intestine, or gut, is a special type of skin.  It is lined with a film made up of billions of beneficial bacteria, just as healthy skin is home to a variety of bacteria, most of which are beneficial. Essential bacteria found in the large intestine are also perceived as essential to the health of the skin and the human body as a whole. Bowe: Probiotics & skin health 2014  Goldin: Probioitics & disease 2008  Sorochan: Probiotics   

There are billions of good and bad bacteria in the gut. The balance between good [80%] and bad bacteria [20%] is essential for good health.   When this balance is compromised, then we can experience a host of health disorders, including lower immunity, diseases and skin disorders. Sorochan: Probiotics  Probiotics, a food supplement, can restore the bacterial balance and comes in many forms, including foods such as yogurt, capsules, powders, and liquids. Restoring the proper intestinal flora through probiotics can rescue your gut health and, in turn, your skin health.  

All three ingredients [ collagen, HA, ceramides ] work together to make skin healthy. The body works wonders in synthesizing all three of these skin ingredients to work together.  But when one or more of these essential ingredients are missing, then we have skin problems like itchy dry skin, psoriasis, eczema and so on.  Cosmetic companies have been trying, for over a century with very little success, to provide topical lotions and creams to fix these problems. 

Skin disorders: A few disorders are summarized in the article skin disorders.

Accumulation of hyaluronic acid in the intestine is linked to numerous diseases and dysfunction in various organs. Kresser: skin nutrition Bowe: Probiotics & skin health 2014  Sorochan: Probiotics 

Excessive exposure to sunlight UVA causes free radicals to form, decreasing the skin's ability to produce HA naturally. This is because free radicals trigger the activity of an enzyme called hyaluronidase.  This enzyme breaks down HA in your skin cells as well as in joints, causing less moisture in the skin and thereby contributing to inflammation, pain and itchy skin. 

Dry skin can be caused by many factors; most often from water lost to the environment, chemical exposures, or from complex nutritional deficiencies.  However, the skin has the ability to heal itself and is virtually indestructible.  Michaels: nutrition & skin health 2011  Most of intrinsic skin aging cannot be avoided. The cumulative effects of decades of skin wear cannot be reversed, although the effects on skin appearance may be temporarily masked.  Michaels: nutrition & skin health 2011

Research:  The majority of the research that has been reported on anti-aging ingredients and skin cosmetics has been done by or been sponsored by major cosmetic companies; with a vested conflict of interest in selling their cosmetic products. US patent 20070077292 A1  Edwards: FDA letter of incompetence  Most research studies use the single subject approach, that is, only one factor in isolation.  Bernhard: vitamin truth 2012   Sorochan: supplements update 2013  Although this may be a good approach when studying the nature of a drug in isolation by itself, such an approach ignores how a drug or nutrient can commingle with other natural body factors as co-factors or helping each other function in the human body.  The human body does not work in isolation!  This issue is reflected in how the medical profession prefers to relieve the symptoms and ignore the cause of health problems.  The sick person’s problems persist in spite of relieving symptoms.  This may also be true with skin disorders. Such as dry skin. 

Skin creams and lotions:  Most commercial skin products on the market today do not restore HA or ceramides to the skin.  The lack of restoration has been inability to transport topical applications into the skin itself. But a new microvesicular emulsion technology claims to provide a novel and cosmetically acceptable delivery system, which contributes to epidermal barrier repair. Bikowski: MVE delivery system 2006  Gatto: designing topical skin products

CeraVe skin lotion: Valeant Pharmaceuticals North America Company [ vested interest company ] claims that microvesicular emulsion technology is their skin lotion and that it is a "true breakthrough in skin care." It is a blend of skin nourishing ingredients [ collagen, hyaluronic acid and ceramides ] blended with a patented Multivesicular Emulsion [MVE] delivery technology that delivers the ingredients slowly, throughout the day, into the skin and repairs the top skin layer.   CeraVe Moisturizing Lotion is touted as noncomedogenic [ does not cause pimples or acne by clogging pores ] and is non-irritating and fragrance-free. Although clinical research trials are lacking, the science is good and this product has promise.  Buyer-user should be aware that this cosmetic cream/lotion lacks independent research to validate the company claims!
