US Patent 9775976 Skin cleansing apparatus with oscillation motion converter

An appliance for facial skin applications having a drive assembly with an oscillating drive shaft. A base member is removably attachable to the oscillating drive member and an infuser member includes a soft tip with a concave surface adapted to hold a skin formulation for infusing into the skin of the user. A spring assembly connects the base member to the infuser member, and is arranged to convert the oscillating action of the drive shaft and the base member to an action having a significant axial component, toward and away from the skin, to produce an infusing action on the skin.
