Juvasonic is a needle-free microdermabrasion device with sonic vibration that gently opens up the outermost layer of your skin for a few minutes, allowing the Klotho serum to actually absorb instead of just sitting on the surface. Normally, your skin’s barrier blocks most of what’s applied topically from getting where it needs to go. Juvasonic temporarily loosens that barrier using gentle vibration, so the active ingredients can reach deeper layers where they actually work.
