Undo The Sun’s Damage To Your Skin

It’s often said that our skin is our largest organ. Our brain or liver are the largest solid organs by mass (which one comes out on top will vary from person to person), our gut is the longest, and our lungs are the largest by surface area. But our skin is large, noticeable, and has a big impact on the rest of our health.

The sun is one of the main damaging factors for our skin; assorted toxins are also a major threat for many people, and once the skin barrier gets broken, it’s a field-day for bacteria.

So, what can we do about it?

Tretinoin: the skin’s rejuvenator

Tretinoin is also called retinoic acid, not to be mistaken for retinol, although they are both retinoids. Tretinoin is much stronger.

As for what it’s stronger at:

It’s usually prescribed for the treatment of sun-damage, acne, and wrinkles. Paradoxically, it works by inflaming the skin (and then making it better, and having done so, keeping it better).

In few words: it encourages your skin to speed up its life cycle, which means that cells die and are replaced sooner, which means the average age of skin cells will be considerably younger at any given time.

This is the same principle as we see at work when it comes to cellular apoptosis and autophagy in general, and specifically the same idea as we discussed when talking about senolytics, compounds that kill aging cells:

Fisetin: The Anti-Aging Assassin

About that paradoxical inflammation…

❝The topical use of tretinoin as an antiacne agent began almost a half century ago. Since that time it has been successfully used to treat comedonal and inflammatory acne.

Over the intervening years, the beneficial effects of tretinoin have grown from an understanding of its potent cornedolytie-related properties to an evolving appreciation of its antiinflammatory actions.

The topical use of clindamycin and tretinoin as a combination treatment modality that includes antibacterial, comedolytic, and antiinflammatoiy properties has proven to be a very effective therapy for treating the various stages of acne

It is now becoming increasingly clear that there may be good reasons for these observations.❞

Against damage by the sun

The older we get, the more likely sun damage is a problem than acne. And in the case of tretinoin,

❝In several well-controlled clinical trials, the proportion of patients showing improvement was significantly higher with 0.01 or 0.05% tretinoin cream than with placebo for criteria such as global assessment, fine and coarse wrinkling, pigmentation and roughness.

Improvements in the overall severity of photodamage were also significantly greater with tretinoin than with placebo.

Several placebo-controlled clinical studies have demonstrated that topical tretinoin has significant efficacy in the treatment of photodamaged skin. Improvements in subjective global assessment scores were recorded in:

49–100% of patients using once-daily 0.01% tretinoin,

68–100% of patients using 0.05% tretinoin, and

0–44% of patients using placebo.❞

~ Drs. Wagstaff & Noble

…which is quite compelling.

This is very well-established by now; here’s an old paper from when the mechanism of action was unknown (here in the current day, 17 mechanisms of action have been identified; beyond the scope of this article as we only have so much room, but it’s nice to see science building on science):

❝Tretinoin cream has been used extensively to reverse the changes of photoaging. It is the first topical therapy to undergo controlled clinical testing and proved to be efficacious. These results have been substantiated with photography, histopathologie examination, and skin surface replicas.

Tretinoin cream has an excellent safety record; a local cutaneous hypervitaminosis A reaction is the only common problem.❞

~ Dr. Goldfarb et al.

Is it safe?

For most people, when used as directed*, yes. However, it’s likely to irritate your skin at first, and that’s normal. If this persists more than a few weeks, or seems unduly severe, then you might want to stop and talk to your doctor again.

(in the case of a young woman who used it 4x daily instead of 1x daily)

Want to try some?

Tretinoin is prescription-only, so speak with your doctor/pharmacist about that. Alternatively, retinol is the strongest natural alternative that works on the same principles; here’s an example product on Amazon 😎

  • Spelt vs Bulgur – Which is Healthier?

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Our Verdict

    When comparing spelt to bulgur, we picked the spelt.

    Why?

    An argument could be made for bulgur, but we say spelt comes out on top. Speaking of “sorting the wheat from the chaff”, be aware: spelt is a hulled wheat product and bulgur is a cracked wheat product.

    Looking at macros first, it’s not surprising therefore that spelt has proportionally more carbs and bulgur has proportionally more fiber, resulting in a slightly lower glycemic index. That said, for the exact same reason, spelt is proportionally higher in protein. Still, fiber is usually the most health-relevant aspect in the macros category, so we’re going to call this a moderate win for bulgur.

    When it comes to micronutrients, however, spelt is doing a lot better:

    In the category of vitamins, spelt is higher in vitamins A, B1, B2, B3, and E (with the difference in E being 26x more!), while bulgur is higher only in vitamin B9 (and that, only slightly). A clear win for spelt here.

    Nor are the mineral contents less polarized; spelt has more copper, iron, magnesium, manganese, phosphorus, potassium, selenium, and zinc, while bulgur is not higher in any minerals. Another easy win for spelt.

    Adding these up makes a win for spelt, but again we’d urge to not underestimate the importance of fiber. Enjoy both in moderation, unless you are avoiding wheat/gluten in which case don’t, and for almost everyone, mixed whole grains are always going to be best.

  • Treadmill vs Road

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Have a question or a request? We love to hear from you!

    In cases where we’ve already covered something, we might link to what we wrote before, but will always be happy to revisit any of our topics again in the future too—there’s always more to say!

    As ever: if the question/request can be answered briefly, we’ll do it here in our Q&A Thursday edition. If not, we’ll make a main feature of it shortly afterwards!

    So, no question/request too big or small 😎

    ❝Why do I get tired much more quickly running outside, than I do on the treadmill? Every time I get worn out quickly but at home I can go for much longer!❞

    Short answer: the reason is Newton’s laws of motion.

    In other words: on a treadmill, you need only maintain your position in space relative the the Earth while the treadmill moves beneath you, whereas on the road, you need to push against the Earth with sufficient force to move it relative to your body.

    Illustrative thought experiment to make that clearer: if you were to stand on a treadmill with roller skates, and hold onto the bar with even just one finger, you would maintain your speed as far as the treadmill’s computer is concerned—whereas to maintain your speed on a flat road, you’d still need to push with your back foot every few yards or so.

    More interesting answer: it’s a qualitatively different exercise (i.e. not just quantitively different). This is because of all that pushing you’re having to do on the road, while on a treadmill, the only pushing you have to do is just enough to counteract gravity (i.e. to keep you upright).

    As such, both forms of running are a cardio exercise (because simply moving your legs quickly, even without having to apply much force, is still something that requires oxygenated blood feeding the muscles), but road-running adds an extra element of resistance exercise for the muscles of your lower body. Thus, road-running will enable you to build-maintain muscle much more than treadmill-running will.

    Some extra things to bear in mind, however:

    1) You can increase the resistance work for either form of running, by adding weight (such as by wearing a weight vest):

    Weight Vests Against Osteoporosis: Do They Really Build Bone?

    …and while road-running will still be the superior form of resistance work (for the reasons we outlined above), adding a weight vest will still be improving your stabilization muscles, just as it would if you were standing still while holding the weight up.

    2) Stationary cycling does not have the same physics differences as stationary running. By this we mean: an exercise bike will require your muscles to do just as much pushing as they would on a road. This makes stationary cycling an excellent choice for high intensity resistance training (HIRT):

    HIIT, But Make It HIRT

    3) The best form of exercise is the one that you will actually do. Thus, when it’s raining sidewise outside, a treadmill inside will get exercise done better than no running at all. Similarly, a treadmill exercise session takes a lot less preparation (“switch it on”) than a running session outside (“get dressed appropriately for the weather, apply sunscreen if necessary, remember to bring water, etc etc”), and thus is also much more likely to actually occur. The ability to stop whenever one wants is also a reassuring factor that makes one much more likely to start. See for example:

  • Does PRP Work For Hair Loss?

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Dr. Ankit Gupta takes us through the details of this hair loss remedy for androgenic alopecia.

    The bald truth

    Platelet-Rich Plasma (PRP) is a controversial treatment for androgenic hair loss.

    What it involves: blood is drawn and separated using a centrifuge. PRP—including growth proteins and hormones—is extracted from the blood; about 30 ml of blood is needed to produce 5 ml of PRP. This is then injected directly into the scalp. As this can be painful, local anaesthetic is sometimes used first. This usually involves monthly sessions for the first 3 months, then booster sessions every 3–6 months thereafter.

    Does it work? Research is young; so far 60% of trials have found it worked; 40% found it didn’t. When it works, effectiveness (in terms of hair restoration) is considered to be between 25–43%. Results are inconsistent and seem to vary from person to person.

    In short, this doctor’s recommendation is to consider it after already having tried standard treatments such as finasteride and/or minoxidil, as they are more likely to work and don’t involve such exciting procedures as injecting your own blood extracts back into your head.

    Fried rice is not most people’s go-to when one thinks of health food, but this one is. It’s packed with plenty of nutrients, many of which are anti-inflammatory, but the real star is the pineapple (with its high bromelain content and thus particularly potent benefits).

    You will need

    • 2½ cups cooked wholegrain basmati rice (you can use our Tasty Versatile Rice recipe if you don’t already have leftovers to use)
    • 1 cup pineapple chunks
    • ½ red onion, diced
    • 1 red bell pepper, diced
    • ½ cup sweetcorn
    • ½ peas
    • 3 green onions, chopped
    • 2 serrano peppers, chopped (omit if you don’t care for heat)
    • 2 tbsp coconut oil
    • 1 tbsp grated fresh ginger
    • 1 tbsp black pepper, coarse ground

    Method

    (we suggest you read everything at least once before doing anything)

    1) Fry the red onion, serrano peppers, and ginger in the coconut oil over a medium heat, stirring frequently, for about 3 minutes.

    2) Add the pineapple, bell pepper, sweetcorn, peas, and black pepper, stirring frequently, for about another 3 minutes.

    3) Add the rice, stirring gently but thoroughly, until fully reheated and mixed in.

    4) Serve, garnishing with the green onions.

    Enjoy!

  • HBD: The Human Being Diet – by Petronella Ravenshear

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    We don’t often review diet books, so why did this one catch our attention? The answer lies in its comprehensive nature without being excessively long and complex.

    Ravenshear (a nutritionist) brings a focus on metabolic balance, and what will and won’t work for keeping it healthy.

    The first part of the book is mostly informational; covering such things as blood sugar balance, gut health, hormones, and circadian rhythm considerations, amongst others.

    The second, larger part of the book is mostly instructional; do this and that, don’t do the other, guidelines on quantities and timings, and what things may be different for some people, and what to do about those.

    The style is conversational and light, but well-grounded in good science.

    Bottom line: if you’d like a “one-stop shop” for giving your diet an overhaul, this book is a fine choice.

    Falafel is a wonderful snack or accompaniment to a main, and if you’ve only had shop-bought, you’re missing out. Plus, with this quinoa-based recipe, it’s almost impossible to accidentally make them dry.

    You will need

    • 1 cup cooked quinoa
    • 1 cup chopped fresh parsley
    • ½ cup wholewheat breadcrumbs (or rye breadcrumbs if you’re avoiding wheat/gluten)
    • 1 can chickpeas, drained
    • 4 green onions, chopped
    • ½ bulb garlic, minced
    • 2 tbsp extra virgin olive oil, plus more for frying
    • 2 tbsp tomato paste
    • 1 tbsp apple cider vinegar
    • 2 tsp nutritional yeast
    • 2 tsp ground cumin
    • 1 tsp red pepper flakes
    • 1 tsp black pepper, coarse ground
    • 1 tsp dried thyme
    • ½ tsp MSG or 1 tsp low-sodium salt

    Method

    (we suggest you read everything at least once before doing anything)

    1) Blend all the ingredients in a food processor until it has an even, but still moderately coarse, texture.

    2) Shape into 1″ balls, and put them in the fridge to chill for about 20 minutes.

    3) Fry the balls over a medium-high heat until evenly browned—just do a few at a time, taking care to not overcrowd the pan.

    4) Serve! Great with salad, hummus, and other such tasty healthy snack items:
