A moisturizing apparatus includes an ion generating device, a mist generating device, and a control device. The ion generating device generates positive ions and negative ions bound to water molecules from the air by an electrical discharge in the atmosphere. The mist generating device reduces the liquid to fine particles in the form of mist and sprays the liquid in the form of mist. The moisturizing apparatus moisturizes the skin or hair, through combined use of application of ions from the ion generating device and spraying of the mist from mist generating device, toward the skin or hair.
