Methods and devices for treatment of skin are disclosed. These methods and
devices use electromagnetic radiation to create networks or patterns of
treatment zones. The networks or patterns of treatment zones comprise at
least four treatment zones, at least two of the treatment zones in the
network or pattern are slanted at angles in the skin, and the treatment
zones extend at least as deep as the dermal-epidermal junction of the
skin. Producing intersecting treatment zones and/or overlapping treatment
patterns can increase the effectiveness of the treatments. The devices
comprise a hand piece operably coupled to a delivery element, wherein
delivery of electromagnetic radiation through the device to a portion of
skin produces a network or pattern of treatment zones. The use of these
methods and devices results in tightening of the skin and/or improvement
in the cosmetic appearance of wrinkles in the portion of skin treated.
