7. Dark Skin ≠ Invincibility to UV Rays

If you've been soaking up the sun with a sense of smug immunity because of your beautifully melanin-rich skin, you might be barking up the wrong UV tree: While melanin does offer some natural protection against sun damage, it doesn't make you invincible to the wrath of solar rays, as even darker skin tones can experience DNA damage and risk skin cancer from excessive sun exposure.

8. The Molecular Bouncer Behind Your Tan

Remember that UV-radiation-induced tan that had you looking like a golden Greek god or goddess basking in the Mediterranean sun? Your skin has a molecular bouncer that keeps the party going: when it senses low doses of solar UV radiation, a retinal-dependent pathway activates melanocytes in your epidermis. This triggers a complex dance of ions and voltages, which boosts your melanin production and gives you that sun-kissed protection.
