1. A skin treatment device, comprising:
- an applicator tip;
a plurality of electrodes configured for contacting a stratum corneum layer of skin external to a patient'"'"'s body, the plurality of electrodes including;
a plurality of voltage to skin elements of a first size, arranged in a cluster, and being further configured for connection to a circuit for delivering RF energy to cause fractional skin treatment; and
a plurality of electrodes sized substantially larger than the first size and arranged at a periphery of the cluster and spaced from the cluster, and wherein the cluster of voltage to skin elements are free of any portion of the larger sized electrode therebetween.

21. A skin treatment device, comprising:
-
a housing; and at least one processor within the housing and configured to control RF energy supplied to a removable applicator tip having a plurality of electrodes configured for contacting a stratum corneum layer of skin external to a patient'"'"'s body, the plurality of electrodes including; a plurality of voltage to skin elements of a first size, arranged in a cluster, and being further configured for connection to a circuit for delivering RF energy to cause fractional skin treatment; and a plurality of electrodes sized substantially larger than the first size and arranged at a periphery of the cluster and spaced from the cluster, and wherein the cluster of voltage to skin elements are free of any portion of the larger sized electrode therebetween; wherein the at least one processor is configured to control RF energy in a manner such that energy is applied to the stratum corneum layer through the plurality of voltage to skin elements of the first size, and such that energy is collected from the stratum corneum on the at least one electrode sized substantially larger than the first size and arranged at a periphery of the cluster and spaced from the cluster. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28)
