Bee venom isn't something a lab invented last year; it's been used on skin since ancient Egypt, and it's stayed in use for one reason: it works with the body instead of on it.
Here's how: think about the last time you scraped your knee. Your body didn't wait around; it rushed its own repair materials straight to the spot and started fixing it, without you doing a thing. That's your skin's repair system.
Melittin triggers that same response on your neck, on purpose, and much gentler. A tiny amount signals the skin, and your body sends its own repair response straight to the crepey, loose areas, every night, without ever actually stinging you.
