Abstract:
1. A skin rejuvenation resurfacing procedure comprising the steps of: anesthetizing with local anesthesia an area of a patient's skin to be transdermally treated prior to the beginning of the resurfacing procedure; inducing a mechanical trauma transdermally into the epidermis, dermis and subcutaneous fat by using an oscillating, reciprocating high speed, non-thermal, needle-based device operated at about 40 cycles per second to induce a purposeful full skin thickness injury and inflammatory response that leads to collagen, elastic and ground substances to resurface said patient's skin, wherein a desired number of passes are made over the surface area of the skin being treated in a criss-crossing pattern or generally circular pattern until there is a deep bruised discoloration to the dermis and edema to the area of the skin being transdermally treated, continuing said procedure until a fraction of the dermis has been mechanically and fractionally abraded and ablated leading to a regeneration and renewal of the epidermal surface and stratum corneum, wherein the needle-based device includes needle depth adjustment means for obtaining a desired transdermal penetration needle tip depth sufficient to penetrate through said epidermis, dermis and into said subcutaneous fat of needle tips of a plurality of needles for the appropriate treatment of the area of the skin being treated, and wherein the needle-based device further comprises: a hand-held portion comprising means for oscillating and reciprocating an elongated needle portion, an elongated needle portion being connected at one end to said hand-held portion and in mechanical communication with said means for oscillating and reciprocating said needle portion, the elongated needle portion having at its opposite end, the plurality of needles configured in a desired array.
