By next year, Americans are expected to spend nearly 11 billion dollars  on skin care annually. By some estimates anyway, the biggest share  of this market goes to “anti-aging” products. Anti-aging… As I noted in an offhand way a few years back, there’s a certain enjoyment in looking good naked (or just looking good), and there’s nothing wrong with that. Looking “good” is largely a reflection of optimum inner health—nothing un-Primal about that. Great health is what we’re all here for. The “extra” rewards that come with it aren’t anything to shake a stick at—or to be sheepish about.
But the health ambition isn’t really what’s behind the statistics above. At their best, anti-aging products boost the body’s natural processes (or at least don’t undermine them with toxins). At their worst, these products promise a way to cheat effort as well as time. While taking care of your skin is part of basic hygiene, too often the claims have more in common with a hat trick than genuine wellness. But which is which?
As our largest organ, and one which is constantly on display to the outside world, our skin is critical to this healthy outward appearance. Conventional wisdom dictates that, as we age, our skin declines, and to a certain degree it’s true. Were we intended to be immortal beings, the Primal strive towards nutritional and lifestyle perfection might be sufficient to maintain your skin’s vibrant status. But…reality is different.
The basic Primal prescription will take your skin’s health far beyond any cream will. (And for today’s purposes, I’ll keep the focus on aging and clarity rather than specific skin conditions.) How far you go beyond that Primal prescription for the sake of your skin’s appearance is up to you, but let’s look at what the basics can accomplish.
Sleep and Skin Aging: You Know There’s a Connection!
Let’s begin with the most obvious. Sleep—it’s when all the cell-healing, hormone-regulating, skin-rejuvenating magic happens, and it might be what people skimp on the most.
Part of that magic involves the production of collagen. Sleep deprivation has a direct impact  on the integrity of the skin, including the production of collagen…and the result is saggier, more wrinkle-prone skin. Skimping a few hours on sleep every night can accentuate the number or severity of fine lines on your face. Not only that, your body dials up blood flow to your skin while you sleep. Inadequate sleep sets you up for an ashen, vampire-esque complexion. Probably not what you were going for.
The beauty here is that small changes can make a huge difference to your sleep regime, and hence your skin. Improving your sleep hygiene may just upgrade your appearance. In fact, you can bet on it.
The More Superficial Benefits of Good Nutrition
A couple of years ago, researchers embarked upon a curious quest  to determine the effect that skin color has on our perception of attractiveness in the opposite sex. Using a bunch of caucasian men and women, the study designers played around with varying degrees of facial coloration using carotenoids and melanin as precursors. They found that those faces which had increased carotenoid coloration were more attractive than those that had increased melanin coloration. Faces with increased coloration in general were also found to be more desirable than those with less pigmentation. The takeaway is this: nutrition may be an even bigger factor in skin health and attractiveness than the sun. A tan is still nice, but the effects of a carotenoid-rich diet comes out on top.
And that doesn’t even take into account the major boon to skin health (and appearance) that comes with avoiding the chronic systemic inflammation of a high-carb diet…
Obviously, good overall nutrition itself is a key for maintaining healthy skin through the years. The continuing media frenzy over antioxidant-rich superfoods may be old news, but it’s good news at that. Nutrient-dense foods do indeed protect your skin from time-induced degradation by slowing the oxidative forces  behind aging of the skin (and everything else). For example, upping your vitamin C intake can enhance collagen production and lowers the incidence  of wrinkles and “senile dryness.” The polyphenols in your green tea may have a photoprotective effect  against excessive sun exposure. Increasing essential fatty acid consumption from the likes of wild-caught salmon or walnuts reduces skin atrophy and wrinkling , as does eating more healthy fats. Many antioxidants and fish oil can reduce inflammation associated with acne and other skin conditions.
Being Primal, this shouldn’t be much of an issue for you. But if you’re not seeing an improvement in your skin after adopting a more Grokish way of life, try playing around with some of these nutritional focal points and add supplementation in the form of a potent, comprehensive multi and a quality fish oil. And you know how I feel about collagen ….
Speaking of supplementation, products known as nutricosmetics are more recent arrivals on the scene. These “beauty pills” derive their claims from doses of anti-aging, free-radical-fighting nutrients like collagen and antioxidants such carotenoids and polyphenols . There you go, right? Well…
I can’t speak to the quality of any of these products, but maybe some of you have had good experiences, and I’m all ears. In cases of specific deficiencies, they might have a role to play. Biotin, a common ingredient in these pills for example, can improve skin’s moisture retention and smoothness and can strengthen brittle hair and nails. For most people, however, a nutrient-rich diet and a good quality multi and fish oil offer more overall benefit and the same result for skin appearance.
Topical applications of nutrients are more complicated still. Many nutrients won’t retain potency in cream or serum form (especially coupled with other ingredients), but science is gaining on those limitations. If there’s sufficient interest, I’ll do a follow-up piece on promising topical formulations.
While we’re on the subject of nutrition… If you’re a regular to MDA, you’ll know that I’m not an alcohol hater. I’ll be the first to admit that alcohol has its uses and enjoyments , but overindulgence takes a considerable toll on the skin (among many other aspects of health…and life). Alcohol abuse has long been associated  with various conditions of the skin, including jaundice, hyper-pigmentation, flushing and psoriasis. While I doubt that you take your alcohol consumption to abusive proportions, these extreme cases indicate that alcohol isn’t particularly skin-enhancing. A booze break may end up being a boon to your appearance.
And Then There’s Gut Health….
Yup, here it is again. The state of your gut biome is central to basically every aspect of your health…so why not your skin?
At the more extreme end of the spectrum, there’s plenty of well-documented links between skin disorders and gut dysbiosis. A 2008 study showed that SIBO is 10 times more prevalent in folks with acne rosacea, and that this skin condition showed marked improvements after treating the SIBO. Moreover, a Japanese study  found that patients with atopic dermatitis had lower counts of (friendly) Bifidobacterium and higher counts of (less friendly) Staphylococcus in their gut. Probably not a coincidence. Other GI disorders, including ulcerative colitis, Crohn’s disease, and celiac disease, have all been linked to negative skin conditions.
From an everyday perspective, it’s all about permeability. I’ve posted about leaky gut  plenty of times in the past, and it’s relevant here, too. The condition contributes to less-than-ideal skin conditions by increasing the level of inflammation in your body. A classic example was provided in one study , whereby patients suffering from acne problems showed positive reactivity to E. coli in the blood while those with no acne showed no reaction at all. Whatever contributes to leaky gut (e.g. sugar, gluten, anti-nutrients, stress, conventional dairy) may also be undermining your skin health.
Leaky gut is a self-sustaining condition that worsens over time, meaning you need to get your gut under control in order to allow your skin to age gracefully. Avoid the aforementioned culprits, and invest in some good probiotics. I can help with that , by the way.
On Sun and Sunscreen
As it happens, both. I’ve talked at long length about how vitamin D is one vitamin that we simply can’t do without . Not only that, there’s plenty of evidence to show that living in areas with more sunshine hours can have a protective effect against many types of cancers. Yes, there may be a relationship between sun exposure and skin cancer, but from an evolutionary perspective it doesn’t really make a lot of sense to me. And there’s research  that speaks to this logical mismatch. With the exception of a select few, most living organisms are designed to thrive in direct sunshine – so why would our skin treat it as public enemy number 1? Not only that, the vitamin D3 that we process from none other than the sun has actually been shown to kill melanoma cells . That’s quite the paradox.
And then there’s the evidence that ample vitamin D can actually inhibit the hallmarks of skin aging .
As with everything, moderation is key. Everyone’s skin is different. And atmospheric filters today aren’t what they were in Grok’s day. It doesn’t make sense to burn or sit in front of a glass window day after day without some kind of shield for your skin.
But before you reach for your pump-action bottle of SPF 50+, take a moment to really think about what you’re slathering on your skin. For starters, that same aluminum that you’ve been taught to avoid in deodorants is often present in conventional sunscreens. Studies show that a slathering of your run-of-the-mill sunscreen can provide up to 200 mg of aluminum . Your average sunscreen also contains both organic and inorganic UV filters, such as benzophenone , which can cause oxidative damage. The jury is still out on zinc oxide nanoparticles , but I’m inclined to use these products very sparingly.
A Bit about Skin Products
As a rule of thumb, unless it specifically states otherwise, your average skin cream, toner, makeup or face wash will degrade your epidermis over time…despite claims of anti-aging grandeur. A few years ago, I provided five reasons why . Those reasons include parabens, pthalates, fragrances, triclosan, and our old friends the UV-filtering chemicals. Cosmetic companies love these ingredients. Your skin (and your health in general) doesn’t.
To really do as Grok did, sure, we’d abandon all soaps, shampoos, toners, cleansers and lotions. Most of us have at least a few things we’d prefer to use, however, which means the next logical step is to seek out products that do what we want them to do while minimizing toxin exposure and disruption of the skin’s own balance. To that end, a few years ago I put together an extensive list of “safer” alternatives to common cosmetics . Since then, the market for these has skyrocketed, and I’ll leave it to sharing on the comment board for updated options. I’ll only note that I choose to sell a particular line of skin and hair products  that cleanse and nurture without stripping the skin of its natural oils or beneficial organisms (quite the opposite if you’re interested in reading more on them). I don’t often sell other companies’ goods, but this one was a personal preference for me.
But back to the big picture…
Research is continuing to highlight the importance of the skin microbiome in ensuring its continued good health and protective functioning. In an excellent article  published in Nature Reviews Microbiology, the authors note that the skin is an “interface with the outside environment and, as such, is colonized by a diverse collection of microorganisms — including bacteria, fungi and viruses…many of these microorganisms are harmless and in some cases provide vital functions that the human genome has not evolved. Symbiotic microorganisms occupy a wide range of skin niches and protect against invasion by more pathogenic or harmful organisms. These microorganisms may also have a role in educating the billions of T cells that are found in the skin, priming them to respond to similarly marked pathogenic cousins.”
Most products, whether washes or creams, end up stripping the skin’s critical microbiome  in addition to the natural secretions that support it. Less is definitely more here.
To Shower or Not to Shower
Water…the most basic element of hygiene. How could we possibly go wrong there? Grok for his part had access to mineral-rich, relatively pristine lakes, rivers and spring. Not so much for moderns. We know that professional swimmers can suffer from a wide range of skin conditions  as a result of the chlorine they regularly immerse themselves in. Sure, your shower water isn’t quite as intensely chlorinated, but it’s still got a reasonable amount, and your skin has a way of absorbing  far more contaminants than you might think. If your skin is particularly sensitive, you may see effects from exposure to regular tap water.
If your water is chlorinated to the point where you can smell it or if you have chronic skin conditions of any kind, consider fitting a filter to your shower head. And ease up on the soap lathering. Your skin was designed to produce it’s own oils to provide natural protection against the elements, and a good lather is going to reverse all that hard work.
Thanks for stopping by, folks. What changes have you seen to your skin since going Primal? What kinds of practices and products do you use for good skin health? Also, what have you stopped doing or buying that made a positive difference?
