One person hovered the tool above their skin in Air Shot mode, while another held it flush to the face. With the Medicube Age-R Booster Pro, my trip to Seoul can wait a little while longer. The Medicube Age-R Booster Pro is like having a mini med-spa session in the palm of your hand—it’s my little not-so-secret-weapon that I can’t imagine going without.
