1. A device for enhancing fluid delivery to a tissue of a subject's skin, the device comprising:
an applicator body extending about a longitudinal axis from a proximal end to a distal applicator tip, wherein the distal applicator tip comprises an opening;
a tissue contacting member carried by the distal applicator tip, wherein the tissue contacting member is movable in the distal applicator tip and comprises an outer surface, wherein the distal applicator tip and the tissue contacting member comprise one or more channels in or around the outer surface and the distal applicator tip, wherein the one or more channels permit fluid flow therethrough in one or more flow pathways, wherein the opening at the distal applicator tip exposes the tissue contacting member to the tissue, wherein the one or more flow pathways form a circuitous flow pathway that extends in or around the distal applicator tip; and
a negative pressure mechanism configured to apply a negative pressure in the applicator body such that the negative pressure is drawn through the one or more flow pathways when the distal applicator tip engages the tissue.
