Abstract: An infuser tip can be used to assist penetration of cosmetic formulas through the outer layer of human skin. Generally described, the infuser tip includes a concave surface or a similarly structured area that retains formula for application to the skin. The infuser tips described herein generally apply cosmetic formula to the skin with a reciprocating (e.g., tapping) motion. Converter assemblies for generating such reciprocating motion from an oscillating motor are provided. Embodiments of converter assemblies generally include an outer housing, a follower elastically coupled to the outer housing, and a contact point configured to slidingly interface a following surface on the follower. In general, the follower is configured for reciprocating motion and the contact point is configured for oscillating motion, both with respect to the outer housing. In this regard, interaction of the contact point and the following surface causes the follower to reciprocate when the contact point oscillates.

The infuser tips described herein generally apply cosmetic formula to the skin with a reciprocating (e.g., tapping) motion. Converter assemblies for generating such reciprocating motion from an oscillating motor are provided. Embodiments of converter assemblies generally include an outer housing, a follower having a cam following surface, and a cam rotatably couplable to the outer housing. In general, the follower is configured for reciprocating motion and the cam is configured for oscillating motion, both with respect to the outer housing. In this regard, interaction of the cam and the cam following surface causes the follower to reciprocate when the cam oscillates.
