  • Depilation apparatus with twisting action only
    Patent number: 6074400
    Abstract: The invention relates to a depilation apparatus, comprising a housing which accommodates a pinching member for consecutively pinching hairs growing from human skin and twisting the pinched hairs about their longitudinal axes.According to the invention, the pinching member holds the pinched hairs in a substantially constant position relative to the housing while twisting the hairs. In this manner, the pinching member does not pull at the hairs and, therefore, does not cause any pain while twisting the hairs. The hairs are twisted by the pinching member until the adhesion between the hairs and the skin tissue is broken or until the hairs are broken beneath the skin surface. After having been twisted in this manner, the hairs can be removed from the skin substantially without pain.
