The Dermagraphics 100% Disposable Pen ®

THE DESIGN (U.S. Patent 5,810,862)The Dermagraphics Pen® comes in 8 different needle configurations.

Single-Row: 8-needle, 10-needle, 12-needle and 14-needle.
Double-Row: 10x2 (20 needles) and 14x2 (28 needles)

Each pen comes in a sterile package, completely assembled. The Dermagraphics Pen® is 100% disposable, resulting in safety for the technician, no clean-up time and great marketing to the consumer.

NOTE: When a tool requires assembly, technicians risk injuring themselves with the needles. This contamination renders the needles unusable until re-sterilized. When a tool requires disassembly and cleaning after use, technicians are at the highest risk for contaminating themselves.

The Dermagraphics Pen® works similar to a crow-quill pen. The needles are side by side and when they are dipped into fluid pigment, capillary action draws the liquid up and holds it between the needles. As the needles are set onto tissue, capillary action draws the liquid down and forms a small puddle at the base of the needles.

The needles used in the Dermagraphics Pen® are extremely fine and flexible, which enables them to enter the epidermal tissue without ANY downward pressure. They are in-line and are set at an angle to eliminate the need for any downward pressure in order to snag the tissue.

NOTE: Tools designed with rigid needles as opposed to flexible needles create frayed tissue. This condition results in poor deposit due to the fact that during exfoliation, the frayed tissue, which holds the deposited pigment, will be lost. Healthier tissue results in better color deposit and retention.

THE MOVEMENT --HOW DOES THE PIGMENT GET INTO THE SKIN?
After the needles are set on the surface of the skin, they are then moved forward and up off of the tissue. During this movement, the needles snag the tissue, creating small, elongated openings. The liquid pigment flows into the elongated holes. These openings close when the needles release the tissue, trapping the pigment in the skin. When this movement is repeated, a build-up of pigment is left in the tissue.


THE BENEFITS OF SHALLOW DEPOSIT The dermal tissue grows new epidermal cells through and over the deposited particles of pigment. By keeping the deposit in the epidermis, these particles are easy to see in the skin. Another benefit of a shallow deposit is the fact that the immune system is less involved with these foreign particles. This results in less encapsulation (scar tissue surrounding the pigment particles) and clearer visibility of the pigment in the tissue.
