1. A skin treatment device, comprising:
- an applicator tip;
a ground electrode arranged on the applicator tip, the ground electrode being configured for contacting epidermis of skin of a patient and being further configured for connection to a circuit for delivering RF energy to the skin, the ground electrode having a ground electrode surface area; and
a plurality of RF application elements arranged on the applicator tip, the RF application elements having a combined application element surface area substantially smaller than the ground electrode surface area, wherein the plurality of RF application elements are configured for connection to the circuit for delivering RF energy to the skin,wherein the plurality of RF application elements are free of any ground electrode therebetween.
