Nonenal doesn't spread evenly it builds up in warm, oil-rich areas. The underarms, the chest, the back of the neck. The exact spots that matter when you hug someone hello, sit shoulder-to-shoulder, or get out on the dance floor.
A full-body wash reaches every one of them in a single shower. Lather, rinse, and you walk out genuinely fresh not just covered up. So the closest part of every hello is the cleanest. You stop monitoring yourself, and start actually being there.
The result is the feeling customers describe again and again: I smell like myself again.
