Story at-a-glance +
By Dr. Mercola

Your skin is your largest organ, and far from being just a passive "covering" on your body, your skin is a complex system made up of nerves, glands and cell layers that play an intricate role in your health.

In fact, healthy skin not only serves as a buffer that helps protect your body from extreme temperatures and chemicals, it also produces antibacterial substances to protect you from infection and enables your body to produce vitamin D when exposed to the sun. It is also densely packed with nerve cells that act as messengers to your brain, making your skin a crucial part of your interactions with the world around you.

Obviously, for these reasons taking good care of your skin is of crucial importance, and will also help your skin appearance to stay soft, supple and glowing, rather than prematurely wrinkled or rough.

5 Common Skin Care Myths

Some of the most widely held "truths" about proper skin care are actually myths. Among the most flagrant and egregious examples are:

Myth #1: All Sun Must be Shunned

Getting safe sun exposure every day is actually one of the best actions you can take for your health, as this is how your body produces enough essential vitamin D, which is known to protect against cancer (including melanoma) and support your immune system, cardiovascular system, kidney function, bones and teeth, muscle strength and much more.

While excessive sun exposure, such as getting sunburned, can certainly damage your skin, sensible sun exposure is not only quite healthy, it's a fundamental step in reaching optimal health.

The skin around your eyes and your face is typically much thinner than other areas on your body and is a relatively small surface area so will not contribute much to vitamin D production. So it is strongly recommended that you protect this fragile area of your body, as it is at a much higher risk for cosmetic photo damage and premature wrinkling. You can use a safe sunblock in this area or wear a cap that always keeps your eyes in the shade.

Myth #2: Tanning Must be Avoided

Assuming you use sensible exposure and avoid getting burned, sensible tanning the "old-fashioned" way (i.e. out in the sun) is perfectly acceptable. The first few days, you should limit your exposure to the sun to allow your body's melanocyte cells to rev up the ability to produce protective pigmentation that not only gives you a tan, but also serves to help protect you against overexposure to the sun.

If you are a fairly light-skinned individual that tends to burn, you will want to limit your initial exposure to a few minutes, especially if it is in the middle of summer.

The more tanned your skin will get, and/or the more tanned you want to become, the longer you can stay in the sun. If it is early or late in the season and/or you are a dark-skinned individual, you could likely safely have 30 minutes on your initial exposure. If you are deeply pigmented and your immediate ancestors are from Africa, India or the Middle East, it is possible you may not even have to worry about how long you are exposed.

Always err on the side of caution however, and let it be your primary goal to never get sun burned, while also protecting the sensitive skin around your eyes and face, as noted above.

Myth #3: Sunless Tanning Lotions/Sprays are Safe

Sunless tanners contain a lengthy list of chemical agents — up to 45 in the case of spray tanners. Many of these agents have never been studied for their long-term effects on human health, because the U.S. Food and Drug Administration does not systematically review the safety of personal care products.

One of the main ingredients in spray tanning solutions is dihydroxyacetone, a color additive that darkens your skin by reacting with amino acids in your skin's surface layer. Dihydroxyacetone is often abbreviated DHA (which should not be confused with docosahexaenoic acid, the healthy omega-3 fat often given the same abbreviation).

Manufacturers of sunless tanning products claim DHA is a simple carbohydrate sugar solution, but some toxicologists disagree. Part of the problem is that the U.S. government's regulations for DHA allow contaminants such as lead, arsenic and mercury. Further, a report by the National Toxicology Program1 suggests the risks of DHA remain unclear, pointing to some evidence that DHA may be a mutagen that could induce breaks in DNA strands, which could contribute to accelerated aging and even skin cancer.

Myth #4: The Higher the SPF of Your Sunscreen, The Better

It's generally unnecessary to purchase sunscreen with a sun protection factor (SPF) greater than 50. The reason for this is because while SPF works by absorbing, reflecting or scattering the sun's rays on your skin, its protective ability is not linear and does not offer a great deal more protection at higher levels.

With regards to SPF, another important factor to remember is that SPF only protects against UVB rays, which are the rays within the ultraviolet spectrum that allows your body to produce vitamin D in your skin. But the most dangerous rays, in terms of causing skin damage and cancer are the UVA rays. This is why you always want to make sure any sunscreen you buy protects against UVA's as well as UVB's … and does NOT contain any common toxic ingredients, such as oxybenzone or retinyl palmitate.

Myth #5: All Skin Care Products on the Market are Safe


This is a Flash-based video and may not be viewable on mobile devices.

It is important to understand that of the 10,500 ingredients used in your personal care products, fewer than 20 percent have been reviewed for safety in the last 30 years, according to an Environmental Working Group (EWG) analysis.2

The reviews that have been done were conducted by a fox in the henhouse—the Cosmetics Ingredients Review, which is run by the cosmetics industry! Not all ingredients need even be mentioned on the label—if they don't want to include one for some reason, they can just leave it off. Therefore, most personal care product formulations are based on nothing more than marketing success, designed to smell good, look good and feel good when you rub them on your skin, regardless of their impact on your health.

But in reality, as the CNN video above describes, many skin care products on the market contain chemicals (including parabens, phthalates, triclosan and others) that have been linked to cancer, hormone disruption, reproductive toxicity and other health problems.

One of the core principles to remember when it comes to skin care is that whatever you slather onto your skin will be absorbed into your body and enter your bloodstream. This is why it's so important to avoid skin care products containing questionable chemicals! Your skin is an excellent drug delivery system, so you should be just as careful with what you put on your skin as you are with what you eat, if not more so, as your gut actually helps protect you against some of the toxins you ingest by filtering them out ... a protection you don't get when a chemical is absorbed through your skin.

Top Dietary Tips for Healthy Skin at Any Age

Ideally, your skin care regimen should include steps to address your skin health from the inside out, as well as from the outside in. The first step should be addressing your diet, as one of the most profoundly effective ways to create the most attractive glow for your skin is by consuming vegetables and fruits that are high in carotenoids. Carotenoids give red, orange and yellow fruits their color, and also occur in green vegetables. Studies have shownthat eating foods with these deeply colored pigments can make your face actually look healthier than being tanned.3

The more red and yellow tones found in your skin, the more attractive the people were found to be. The redder tones are caused when people are flushed with blood, particularly if the blood has lots of oxygen in it. Researchers found that, given the choice between skin color caused by suntan and skin color caused by carotenoids, people preferred the carotenoid skin color, so if you want a healthier and more attractive skin color, you are better off eating a healthy diet.

In order to have clear, healthy skin, you need to make sure your body is relatively free of toxins, so cleansing your body of dangerous substances while putting in the finest nutrients is essential. The organs responsible for providing you with beautiful skin include your liver, kidneys, adrenals, thyroid, and your large and small intestines.

Your liver and kidneys are the two organs that filter out impurities on an ongoing basis. If your diet is less than ideal, these two organs can easily become overtaxed, which can lead to breakouts and other skin problems.
Your adrenals make many essential hormones, such as pregnenolone, DHEA, estrogen, progesterone and testosterone. Hormonal imbalances can also result in problematic skin conditions, so adrenal function is important as well.
A well-nourished, energetic thyroid also provides hormones and works closely with your adrenals to create energy. Dry, flaky, sluggish skin can be evidence of a weak thyroid.
Your small- and large intestines provide nutrients to all your organs and remove waste products from your body. When waste meant for elimination remains in your intestines your skin becomes thick, oily and blemished. Pure, flawless skin is typically a reflection of clean intestines.
Eating a healthy diet as described in my nutrition plan, which focuses on whole, bioavailable organic foods, is your number one strategy for helping your body detox naturally while supplying the necessary nutrients your skin needs to thrive. That said, some foods are particularly effective at promoting beautiful, clear skin, including:

Trong số trắng trợn nhất và egregious ví dụ là:Chuyện hoang đường #1: Tất cả Sun phải được xa lánhNhận được ánh nắng mặt trời an toàn hàng ngày là thực sự là một trong những hành động tốt nhất bạn có thể làm cho sức khỏe của bạn, vì đây là cách cơ thể của bạn sản xuất đủ cần thiết vitamin D, được biết đến để bảo vệ chống lại ung thư (bao gồm cả khối u ác tính) và hỗ trợ hệ thống miễn dịch của bạn, Hệ thống tim mạch, chức năng thận, xương và răng, sức mạnh cơ bắp và nhiều thêm.Trong khi ánh nắng mặt trời quá nhiều, chẳng hạn như nhận được sunburned, chắc chắn có thể làm hỏng làn da của bạn, ánh nắng mặt trời hợp lý là không chỉ khá lành mạnh, nó là một bước cơ bản trong việc tiếp cận sức khỏe tối ưu.Da xung quanh mắt của bạn và khuôn mặt của bạn là thường mỏng hơn nhiều so với các khu vực khác trên cơ thể của bạn và là một khu vực bề mặt tương đối nhỏ vì vậy sẽ không tham gia vào nhiều để sản xuất vitamin D. Vì vậy nó được khuyên rằng bạn bảo vệ khu vực này dễ vỡ của cơ thể của bạn, vì nó là một nguy cơ cao hơn nhiều cho Mỹ phẩm ảnh thiệt hại và nhăn sớm. Bạn có thể sử dụng một sunblock an toàn trong lĩnh vực này hoặc mặc một nắp mà luôn luôn giữ mắt của bạn trong bóng râm.Chuyện hoang đường #2: Thuộc da phải được tránhGiả sử bạn sử dụng hợp lý tiếp xúc và tránh nhận được đốt cháy, hợp lý thuộc da cách "lỗi thời" (tức là ra trong mặt trời) là hoàn toàn chấp nhận được. Vài ngày đầu tiên, bạn nên hạn chế của bạn tiếp xúc với ánh mặt trời để cho phép các tế bào của cơ thể melanocyte để rev lên khả năng sản xuất sắc tố bảo vệ mà không chỉ cung cấp cho bạn một tan, nhưng cũng phục vụ để giúp bảo vệ bạn chống lại tiếp xúc quá nhiều với ánh nắng mặt trời.Nếu bạn là một công bằng da sáng cá nhân mà có xu hướng để đốt cháy, bạn sẽ muốn giới hạn tiếp xúc ban đầu của bạn cho một vài phút, đặc biệt là nếu nó là ở giữa mùa hè.The nhiều hơn tanned da của bạn sẽ nhận được, và/hoặc hơn tanned bạn muốn trở thành, dài, bạn có thể ở lại trong ánh mặt trời.

Nếu bạn được sâu sắc tố và tổ tiên của bạn ngay lập tức là từ Châu Phi, Ấn Độ hay Trung Đông, có thể bạn có thể thậm chí không phải lo lắng về bao lâu bạn đang tiếp xúc.Luôn luôn err ở mặt bên của thận trọng tuy nhiên, và để cho nó là mục tiêu chính của bạn để không bao giờ có được mặt trời thiêu đốt, trong khi cũng bảo vệ làn da nhạy cảm quanh mắt và khuôn mặt, như đã nói ở trên.Chuyện hoang đường #3: Các loại kem/phun thuộc da Sunless là Két an toànSunless tanners chứa một danh sách dài của lò-lên đến 45 trong trường hợp của tanners phun. Nhiều người trong số các đại lý không bao giờ có được nghiên cứu nhất của ảnh hưởng lâu dài trên sức khỏe con người, vì u. s.

Dihydroxyacetone là thường viết tắt là DHA (mà không nên bị nhầm lẫn với docosahexaenoic acid, chất béo omega-3 lành mạnh thường được đưa ra cùng một tên viết tắt).Manufacturers of sunless tanning products claim DHA is a simple carbohydrate sugar solution, but some toxicologists disagree.
