Treatment of telangiectasias with the 532-nm and the 532/940-nm diode laser.

Recently, a dual-wavelength 532/940-nm laser has become available for treatment of facial vascular lesions as an alternative to the flashlamp pumped-dye lasers. Most facial vascular lesions will respond to the 532-nm wavelength. However, some of the larger and deeper lesions are resistant to this laser. The 940-nm wavelength can be used to treat these resistant lesions. Sixteen patients with 532-nm laser-resistant vascular lesions were treated with the 940-nm laser. Fourteen of these 16 patients had improvement in their telangiectasia in response to these treatments. Most facial l telangiectasias respond well to treatment with the 532-nm laser. However, some of the larger and deeper lesions will not respond well to this laser. The 940-nm wavelength laser can be used to treat these 532-nm laser resistant lesions.

Laser facial plastic surgery for men.

The demand for laser facial plastic surgery for men has been increasing. Because men tend not to wear make-up and do not wish to take the time off from work associated with surgical procedures, they prefer laser type procedures that usually have minimal associated recovery. These procedures can be used to treat multiple conditions including: photoaging, acne, acne scars, superficial cutaneous problems, and rhinophyma.

Long-pulse 532-nm diode laser for nonablative facial skin rejuvenation.

OBJECTIVE: To evaluate the efficacy of a long-pulse 532-nm frequency doubled Nd:YAG laser for nonablative facial skin rejuvenation. METHODS: Patients received a series of treatments to one side of their periorbital and midfacial region. The opposite side was not treated, and served as a control. An evaluation of the results was performed by the patients and by single-blinded review of digital photographs. RESULTS: The patients involved in the study all noted an improvement in their appearance. The single-blinded observers noted a significant improvement in 5 (71%) of the 7 patients. On average, these patients had a 25% improvement in their appearance. CONCLUSIONS: In this preliminary study, the long-pulse 532-nm Nd:YAG laser was effective for the treatment of photoaging. The patients were pleased with the results, particularly because they were able to obtain an improvement in appearance with minimal discomfort and without any loss of time from their regular activities.

Evaluation of acne scar treatment with a 1450-nm midinfrared laser and 30% trichloroacetic acid peels.

OBJECTIVE: To evaluate the efficacy of treatment of established acne scars with a sequential combination of treatment using a 1450-nm, midinfrared, nonablative diode laser with dynamic cooling spray and 30% trichloroacetic acid peels. METHODS: In this prospective study 9 patients with atrophic rolling, boxcar, or both types of scars received 4 monthly treatments using a 1450-nm, midinfrared, nonablative, diode laser with dynamic cooling spray followed by 2 bimonthly treatments with 30% trichloroacetic acid peels. Blinded evaluators and the patients rated the results. RESULTS: The group of patients in this study had a greater improvement in their acne scars than has been reported for nonablative laser treatments by other authors. Comparing the results of treatment 2 months after the laser treatments with 2 months after the chemical peels, the patients had a greater improvement after the additional chemical peels. There were no complications in this study. The patients were able to continue all of their regular activities throughout the study. CONCLUSION: This sequential treatment regimen using the 1450-nm, midinfrared, nonablative diode laser with dynamic cooling spray and 30% trichloroacetic acid peels produced a noticeable improvement in the acne scars without any associated morbidity.
