The jojoba beads contained in HydroPeptide's exfoliating cleanser are made from pure jojoba wax, which is produced in the seed of the jojoba plant, a shrub native to northern Mexico. Jojoba beads have no sharp edges, so they won't cause microscopic cuts that invite bacteria into the skin's surface — an ideal exfoliant, to be sure.

HydroPeptide Cleanse: Anti-Wrinkle Exfoliating Cleanser, $38, available at HydroPeptide.
