Maintaining Healthy Skin

The skin serves numerous functions - detoxifying, protecting, regulating - but the primary protective or barrier function is the most obvious. The top layer of skin cells has the most important function in maintaining the effectiveness of the barrier. Here the individual cells overlie each other and are tightly packed, preventing bacteria from entering and maintaining the water-holding properties of the skin.
Fatty substances (lipids) are secreted by the cells during the course of their journey from the base layer of the skin to the top. These lipid molecules join up and form a tough connecting network, in effect acting as the mortar between the bricks of a wall.

The cell wall barriers are simply layers of fats that surround the watery contents. Therefore, the communication mechanisms must operate through these fatty cell walls. In fact, many of the substances that are involved in this communication process are various fats since it is easiest for fats to move within the fatty layers that comprise the cell walls. Despite its bad reputation, proper fats and cellular fats are of major importance in our body’s biochemistry and physiology.

Damage to the skin barrier can result from a combination of genetic predisposion and exposure to sensitizing chemicals and other substances. That is why avoiding irritants is as important as using products that help. In skin care, the most common irritants are usually perfumes and preservatives.

Fatty substances control the majority of our body’s physiology through receptors that activate many important genes. Likewise, our skin barrier is comprised of a supporting structure of collagen, a protein that contains fats that serve a critical function. These fats prevent the excess loss of water through our skin and prevent the cells of our body from becoming dehydrated and dying.

A major sign of a defective skin is the dryness that results from excessive water loss. This water can not be applied topically but must be ingested. To prevent the excessive water loss and the resulting dry skin, we must repair the skin barrier. We find that the skin composition in individuals with dry skin is due to an improper mixture of the skin fats. This is commonly due to a deficiency in our diet of the correct fats, those contained in natural olive oils, avocados, and healthy nuts, etc. On a nutritional basis, we can provide these necessary fats through the skin sometimes through topical treatments containing natural butters or oils, like Shea, olive and cocoa butter. The epidermis is not a usual means to acquire nutrition but it can absorb enough fatty substances to correct the fat imbalances that are the cause of the defect in the skin’s barrier function and thus correct the dry, itchy skin or sensitive skin problem. Try to be aware of chemical preservatives in any topical products you do use.

Although many products today are labeled “fragrance free,” that is really a misnomer. Nearly all products contain some fragrance to mask their chemical odor; so-called fragrance-free products may just contain fewer chemicals than others. What’s more, the fragrances used in many products (even pricey perfumes) are commonly synthetic. For sensitive individuals, this chemical brew can be a problem To make matters worse, many natural fragrances are now extracted using harsh solvents rather than old-fashioned distillation methods, in which fewer chemicals come into contact with the essential oil of the flower. Unless you can determine the extraction method used, be cautious. This is one reason many individuals react negatively to the essential oils used in aromatherapy massages and related products – many are of a synthetic, chemical composition.

According to several studies, various preservatives including formaldehyde, parabens, and others commonly used in skin, hair, and beauty products can also provoke allergic reactions. Although the preservatives are needed to maintain product shelf life and only minute amounts are present in any given product, many products contain these same chemicals, including skin care products, makeup, medications, antiperspirants, toothpaste, and foods. Many of these products are used on a daily basis, causing a higher reaction rate. As a result, the overall exposure to these harmful ingredients is higher than would occur if only a single product were used. Studies show that massage therapists have more contact dermatitis – or skin inflammation - due to exposure to these extracts.

Until recently, few studies investigated the cumulative impact of repeated exposures to preservatives in a variety of products and ingredients. For the majority of people, these product preservatives are an additional benefit, not a problem. But, as the chemical compositions increase, so do the allergic reactions.
If you suffer from sensitive, allergic skin or severe dry skin, you may be among those who will have a problem or reaction to these chemical-laden products. In this case, it is your role as an informed consumer to carefully read labels for all products that come into contact with your skin - internally or externally- to assure that they don’t contain the listed ingredients that you must avoid. Your skin barrier does a lot to protect you naturally, help it out when you can and feed it nourishing chemical-free products whenever you can.

The Mediterranean Diet

We all know how important diet is to building healthy, beautiful skin. But did you know eating the right foods and avoiding the wrong ones can actually help prevent wrinkles and minimize the signs of aging?
According to a recent article in the UK’s Daily Telegraph, “Eating a Mediterranean diet can halve the risk of the most dangerous form of skin cancer, research suggests.” The recent study may eventually prove regular intake of fruit, vegetables, nuts and fish may protect against malignant melanoma.

The” Mediterranean diet,” which features plenty of vegetables, legumes, and olive oils, may be a catalyst for the body to absorb and benefit from fat-soluble antioxidant vitamins and phytochemicals, such as vitamin E, lycopene, and isoflavones. In this light, organic produce has been shown to contain a higher level of beneficial antioxidants than conventionally raised fruits and vegetables.

So, what does all this mean if you suffer from dry skin or sensitive skin? With dry skin issues, it is important to get the right types fats into your diet. But what are the right types of fats? For example, increased intake of saturated fat and monounsaturated fat in the diet has been associated with a decrease skin hydration. So consuming some saturated fats but not too many, seems to be best.
Countless studies show that an omega-3 fat deficiency is associated with dry skin and skin problems like eczema. That’s why it is important to consume adequate amounts of these essential fats, found in fatty fish, fish oils, flaxseeds, flaxseed oil, etc.

Be aware of the difference from the omega-6 polyunsaturated vegetable oils (including corn, canola, and safflower), formerly hailed as healing for the heart. Meaning, most need to eat more omega-3s and less omega-6 oils.
The dairy products you eat (and avoid) can also make a difference in skin aging. Butter, full-fat milk, margarine, and sweets should be minimal, while yogurt, cheese, and reduced-fat milk are neutral in their aging effects.

The epidermis (upper layer of the skin) is composed of 25 percent monounsaturated fatty acids. In the cell membranes, both monosaturated fats and saturated fats resist oxidation, a key process in cellular aging. Omega-6 polyunsaturated oils, on the other hand, contribute to the production of free radicals, the by-products of oxidation - also the cause of the skin aging process. This would increase both wrinkling and the risk of developing skin and other cancers, including melanoma. Polyphenols, found in fresh fruits, vegetable and herbs can protect the body’s cells against the damaging effects of oxidative stress, a process by which oxygen-rich molecules can attack and destroy cells in much the same way as rust rots a car.
Therefore, it is beneficial to eat more olive oil (a monounsaturated) while avoiding omega-6 polyunsaturated oils, such as corn, canola, safflower and others. Included in this list of foods to avoid, are the trans fats, present in margarine, most baked goods, fried, processed foods, and sweets, which are oxidized polyunsaturates, making them even more detrimental. In certain studies they have been shown to block healthy Omega -3 fats. High trans-fats content may interfere with the hormonal pathways needed for healthy fat metabolism and preventing inflammation.

Consuming the omega-3s and avoiding unhealthy oils that block them will help the body absorb the vital lipids needed in the skin cells and improve the hormonal actions. Since skin aging is caused by hormonal shifts that occur naturally in the aging process, it’s best to eliminate the polyunsaturated and trans fats as much as possible.

Fish oils and fish are the purest sources of omega-3 fatty acids,which can increase the lipid content of your cells. These fats have been shown to improve psoriasis and other severe dry skin conditions. If you are pregnant or nursing, please be aware of the mercury content in your fish - which has been shown to cause detrimental effects to mothers, and young children, so supplements may be the best way of obtaining these fats vital to skin health.

Dry, sensitive, and wrinkled skin can also be helped with a diet rich in antioxidants obtained from fresh fruits and vegetables, such as spinach, kale, collard greens, turnips, romaine lettuce, broccoli, leeks, corn, peppers, peas, and mustard greens. Egg yolks and oranges contain the antioxidant lutein. Lutein is an important natural antioxidant that may help your eyes stay healthy while maintaining the health of your skin.
So, to recap your skin-healthy diet should include:
•    Fats from whole foods-nuts, seeds, olives, and avocados
•    A wide variety of whole plant foods
•    Monounsaturated fats, such as olive or nut oils
•    Good sources of omega3 oils (never heated) or in capsule form
•    Moderate use of omega-6 oils (corn, safflower, canola and soy oils)
•    Limited amounts of processed foods and deep-fried foods
•    Pure sources of omega3 fats, including a source of essential fatty acids (EFA)

Healthy Diet Helps Dry Skin

There are lots of things you can do with your diet and supplements that can help your dry skin. To combat dry skin, your body needs fats to build fat-rich cells that hold on to moisture. Saturated, monounsaturated and omega-3 fats are key components in the cell membranes . Vegetarians (who eat eggs and dairy products but not meat) eat about one-third less saturated fat than the average meat eater. Vegans (who eat no animal products of any kind) only receive about one half as much saturated fat as the average meat-eating American. As a result, they obtain from their diet much less cholesterol than omnivores.

Although cholesterol has received a bad name due to concerns about its connection with cardiovascular illness, recent studies show that it does have benefits, particularly for some post menopausal women. Cholesterol is needed for key body functions within the cellular membranes that impact the skin. For example, studies show that cholesterol-lowering drugs can lead to dry skin, while decreased levels of essential fatty acids have been associated with dry skin, dry hair, and brittle nails. If you have these symptoms and you are a vegetarian you may want to speak to your doctor to see if you may suffer from an essential fatty acid deficiency.

The best way to assure you get a healthy diet of skin-enhancing  fats is by eating a wide variety of whole plant foods. You can get fats from nuts, seeds, olives and avocados Use olive oil, replete with monosaturated fat, for cooking and salad dressings. Coconut oil is also an excellent alternative for it retains its stability at high temperatures. Try to avoid processed  foods and deep-fried foods that are rich in trans fats and omega-6 polyunsaturated fats. These fats contribute to the production of free radicals, the by-products of oxidation, which is a skin aging process that antioxidant vegetables help tame. Although for many years polyunsaturated vegetable oils, like canola, corn, safflower, and soy were recommended, canola oil is actually unstable when heated and the processed used to stabilize it turns a certain percentage of the oil into a trans fat.

Eating the undesirable fats found in these oils (as well in trans-fat containing foods such as margarine, most baked goods, fried foods, processed foods and sweets )may increase both wrinkling and the risk of developing skin and other cancers including melanoma. Vegetarians can eat eggs and dairy to obtain saturated fats while vegans can obtain them from coconut oil.

Fish oils are good sources of omega-3 polyunsaturated fatty acids which can increase the lipid content of your cells. They can be obtained from fish like salmon, as well as supplements with Omega-3 or Cod Liver Oil capsules. Omega-3s help your skin by providing essential fats needed for cellular integrity while they also prevent inflammation which can lead to the formation of dark spots in pigmented skin types.
Antioxidants are helpful in fighting free radicals - renegade oxygen molecules that cause cellular aging and wrinkles.

Also look for products that contain ingredients that help your skin retain moisture, such as essential fatty acids along with ingredients like lecithin to strengthens kin cell membranes. Look for products that are also third party tested to ensure they are free of environmental toxins. It is important in purchasing essential fats to ensure that you find a pure, well-tested source, free of environmental contaminants.

Several studies have suggested that it is better to get antioxidants through natural food sources instead of supplements, but if this is not possible or additional vitamin intake is needed, supplements can be a valuable help.

SUPPLEMENTS
The following oral supplements that contain the below nutrients can all be helpful to your skin:

Selenium is a powerful antioxidant mineral. Selenium. Some scientific evidence suggests that consumption of selenium may reduce the risk of certain forms of cancer. However, FDA has determined that this evidence is limited and not conclusive. Vitamins A, C, E, B5, alpha lipoic acid, and grape seed extract,  Ester-C , CoQro, lutein, as well as zinc, selenium, copper, and lycopene. Take these supplements according to the manufacturer’s directions.

Taking glucosamine supplements increases hyaluronic acid production. Hyaluronic acid (also called Hyaluronan) is a component of connective tissue whose function is to cushion and lubricate.  Vitamin C can be especially beneficial,  although it is tough to get ample quantities from supplements, every little bit helps. Be cautious of a laxative effect from vitamin C. take small doses at first then build gradually to endure to reaction has occurred. Buffered vitamin C is also available for those with sensitive digestive tracks. Complementing your daily skin care regimen with skin supportive supplements can boost the benefits to your skin.
