Hydro Dermabrasion Device With Microneedles

An applicator for use with a handpiece of a hydro dermabrasion device for treating skin, having solution supply and suction apertures, comprising:

• a cylinder that connects to the handpiece, comprising an upper cylinder body with upper and lower walls and a lower cylinder body;
• the upper cylinder body comprising an upper chamber, a lower chamber and a connecting chamber;
• wherein the upper chamber has an open top and a bottom with a supply aperture and a suction aperture and is removably attachable to the handpiece, and the lower chamber and connecting chamber are connected and each has an open bottom;
• The lower cylinder body being dimensioned to slidably fit inside the lower chamber of the upper cylinder body, and having a first ledge and a second ledge;
• a microneedle array base holder, with a supply lumen and a suction lumen, attached to the bottom of the upper chamber of the upper cylinder body;
• a microneedle array base attached to the holder, having supply and suction lumens therethrough and a plurality of microneedles extending therefrom;
• a safety plate having apertures for the microneedles and supply and suction lumens therethrough, attached to the lower cylinder body below the microneedle array base;
• a spring positioned between the lower wall of the upper cylinder body and the first ledge around the lower cylinder body;
• and
• a microneedle penetration depth controller;
• Wherein the supply apertures and supply lumens are aligned to form a continuous solution supply path through the applicator, the suction apertures and suction lumens form a continuous path through the applicator and the microneedles are reciprocally passable through the safety plate to the treated skin at a depth regulated by the depth controller.
