Nonablative Dermal Remodeling

Multicenter study of noninvasive radiofrequency for periorbital tissue tightening

“…A better understanding of these variables is likely to lead to more impressive outcomes in the future. Quantifying the efficacy of noninvasive cosmetic procedures is notoriously difficult [8,11]. Histologic changes, although interesting and objective, do not always correlate with aesthetic improvements.…”

“…Nonablative technologies have been developed in an effort to reduce complications, minimize perioperative pain, and shorten the healing time by creating a dermal wound without ablating the epidermis [8]. Examples of these newer noninvasive technologies include CoolTouch infrared laser (1,320 nm), pulsed dye laser (585, 595 nm), intense pulsed light sources (585-1,100 nm), Nd:YAG (1,064 nm), Smoothbeam infrared laser (1,450 nm diode), ultrasound, and microdermabrasion [9,10].…”

Single-Pass Carbon Dioxide Laser Skin Resurfacing Combined With Cold-Air Cooling

“…Its efficacy, however, is currently the focus of heated debate among some authors. 4,10,22,23 In summary, the present method of using air cooling along with single-pass CO 2 laser skin resurfacing is an effective technique that can be ranked between multiple-pass ablative CO 2 or erbium:YAG laser skin resurfacing and subsurfacing in treating incipient and light perioral and periorbital wrinkles. Unlike conventional skin resurfacing and single-pass resurfacing with alternative forms of analgesics, our procedure clearly reduces intraoperative pain and postoperative adverse effects to an easily tolerated level.…”

Results of nonablative wrinkle reduction with a 1,450-nm diode laser: Difficulties in the assessment of “subtle changes”

“…Despite multiple reports claiming positive results for photorejuvenation type II [18], the efficacy of nonablative wrinkle reduction, however, is still discussed controversially [14,[19][20][21][22].…”
