I'd use the search bar to find our old conversation and reply there but that's gone for now but I always wanted to get back to you on this when you asked me about my opinion on sunscreen and skin-cancer:
Sunscreen being the solution to skin cancer has always struck me as misleading. What increasingly appears to drive skin cancer isn’t necessarily the sun itself, but rather the fact that many people today have compromised mitochondria due to chronic metabolic dysfunction—especially from persistently activating
the glucose–fatty acid (Randle) cycle.
If you avoid this metabolic stress, maybe support your mitochondria with nutrients like taurine and a full-spectrum vitamin E complex, avoid smoking and drinking, and exercise regularly, your mitochondria should hopefully gradually recover their resilience and function and drastically lower your risk for any cancer at all.
What also goes overlooked is the role of dietary fat in skin health. Evolutionarily, humans consumed mostly saturated and monounsaturated fats
as hyper-carnivores (
as did our neanderthal cousins), with polyunsaturated fatty acids (PUFAs) making up a small minority—usually less than 10–15% of total fat intake. The fatty acid composition of your skin reflects what you eat. When your epidermal tissues are rich in more stable fats like SFAs and MUFAs, UV rays cause minimal peroxidation. But when your diet is disproportionately high in unstable omega-6 PUFAs—especially from processed foods and seed oils—your skin becomes far more vulnerable to lipid peroxidation, inflammation, and downstream oxidative stress when exposed to sunlight.
This instability likely contributes to exaggerated sunburn and, in the presence of mitochondrial dysfunction, raises the risk of skin cancer. It’s no coincidence that many light-skinned people such as those of European descent report significant improvements in sun tolerance after removing seed oils from their diet for a prolonged period. Some venturing so far as to report never experiencing sunburn again:
Ultimately, the solution to healthy, resilient skin isn’t lathering yourself in synthetic concoctions (sunscreens)—many of which contain potentially harmful compounds like synthetic estrogens and parabens—but rather restoring your body to metabolic balance through nutrient-dense, evolutionarily consistent eating and an overall healthy lifestyle. And this is to say nothing of unnumerable benefits that come from regular sun exposure:
Almost all animals love basking in the sun for a reason. Also, the funny thing is, even when you are metabolically unhealthy (like most modern people) and eating the usual plant-heavy, PUFA heavy, and processed diet; the rates for skin cancer among black folks are pretty much near non-existent:

1 in 1,000 among madow Americans compared to
1 in 33 among cadaan Americans. That's how resistant your higher melanin index makes you even when you're someone eating garbage. Anyway, this all also applies to skin aging and weathering, more or less. I really wouldn't ever waste a dime on sunscreen...
