Nonablative Wrinkle Reduction: Treatment Results With a 585-nm Laser

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

“…These include subsurfacing with both nonablative lasers and intense pulsed light systems, approaches whose efficacy has never been completely convincing, especially with regard to reduction of wrinkles alone. 4,10,11 Another strategy is single-or double-pass CO 2 laser resurfacing, which has been reported to result in more rapid reepithelialization, fewer and less severe adverse effects, and good prospects of success. [12][13][14][15][16] The postoperative adverse effects of ablative wrinkle treatment are not the only important consideration in regard to patient satisfaction; preventing intraoperative pain is also a major factor.…”

“…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.…”

Patient satisfaction and efficacy of accent high-intensity focused ultrasound for face lifting

“…Thus, in recent years, non-invasive and non-ablative procedures have attracted attention with the hope of achieving skin tightening effects close to those of ablative lasers while avoiding long recovery times and potential complications [9][10][11]. Nonablative rejuvenation (NAR) devices have been designed to induce thermal injury within the dermis without epidermal damage [12][13][14]. However, laser energy can be diffracted, absorbed, or scattered, resulting in suboptimal energy penetration [15,16].…”

Skin fluorescence controlled photodynamic photorejuvenation (wrinkle reduction)

“…Non-ablative wrinkle reduction (photorejuvenation type II) has most successfully been performed with long wavelength lasers [15][16][17][18], radiofrequency devices [19,20] or optical infrared devices [21,22], all with relatively little or no type I photorejuvenation effect reported.…”
