  • Patent number: 4498474
    Abstract: An epilator system for removing hair, employing a wetting fluid with ionic properties. The ionic wetting fluid is applied to the hair down into the follicle to the papilla and preferably a high-frequency voltage lower than used in conventional epilators is then applied in the region of a wetted hair. The hair is drawn easily from the follicle, generally without regrowth. In preferred embodiments, two or more fluids are applied sequentially, the last having lower ionic activity, but preferably having activity equivalent to at least about 25 ppm sodium chloride in water solution. The ratio of ionic activity of the preceding fluid to the ionic activity of the final fluid is in the range of about 10:1 to 1:1, preferably about 5:1. Preferably the preceding fluid is applied to the skin, wiped leaving a deposit in the pore, and the last fluid is applied. An epilator fluid and epilator kit are also claimed.

  • Patent number: 4317450
    Abstract: An epilator system comprising the combination of an electric source for applying a regulated voltage to a region of a hair and a wetting solution with ionic properties. For hair removal, the wetting solution with ionic properties is applied to the hair down into the follicle to the papilla and preferably a high-frequency voltage lower than used in conventional epilators is then applied to the wetted hair.
