While many devices are tailored for skin tightening in the neck, the greater challenge remains how to improve the tone and texture of neck skin. Technologies that tighten the neck skin sometimes do not address issues like sun damage, discoloration, and even wrinkling and that can extend down to the chest area.
To this end, I still believe laser resurfacing has a space in treating a wide variety of issues in the skin of the nexk and uppe chest. My protocol includes various RF devices for tightening (Thermage, Ulthera, or Viora), but on the surface I still like fractional ablative Co2 laser resurfacing. Any device can be used as long as it can be compatible for these settings. My device of choice remains the Lutronic Eco2 laser.
The treatment protocol I use focuses on a spot size of about 300 microns, with about 7.5 percent coverage repeated three times. In the submental area (under the chin), one can drop down to 120-150 micron spot size with about 10 percent coverage, but outside this area it is important to increase spot size. As for depth, in the submentum I have found it safe to treat down to 1000-1200 microns, but outside this area I like to stay in the 300-500 micron depth range. Hope this helps and good luck!!
