Calling sunscreen anti aging is a joke

You’re blocking the very UV and infrared light your skin uses to build collagen, make Vitamin D3, generate nitric oxide, and stimulate melanin based photo-protection

All sunscreens (both chemical and mineral based) disable natural photoadaptation and mitochondrial signaling, processes that actually preserve skin structure and youth

“When it’s black, it don’t crack” is a cultural truth pointing in the direction of eumelanin, but also melanin at large

Nature already equipped melanin rich skin with a full spectrum sunscreen and anti aging mechanism

And guess what

All skin types have melanin, you just have to maximize its longevity and function through a circadian aligned lifestyle and sunbathing framework
