Facial Telangiectasia and Pigmented Lesions with 532nm laser

Facial Telangiectasia and Pigmented Lesions

Facial telangiectasias are common lesions resulting from multiple factors. Multiple therapies and devices have been used for the treatment of facial telangiectasia with varied success and complication rates. The 532nm diode (diode-pumped, frequency-doubled Nd:YAG) laser is compared with other laser and nonlaser modalities for the office-based cosmetic surgery practice.

The absorption of green light at 532 nm by oxyhemoglobin is very high, resulting in a high extinction coefficient. The 532nm green light wavelength is also absorbed by melanin. This is an advantage, for the 532nm (DP FD Nd:YAG) laser can be used to treat pigmented lesions. Although used frequently, care should be taken when treating darker skin to avoid epidermal injury. The 532nm diode (DP FD Nd:YAG) laser produces a 532nm wavelength that is strongly absorbed by oxyhemoglobin.

Multiple 532nm lasers are available for the treatment of telangiectasias and pigmented lesions. The 532nm (DP FD Nd:YAG) laser is an extremely portable solid-state laser that enables transportation between offices or treatment rooms. The small handpieces are very flexible and are well suited for the precision tracing of individual telangiectasias. The 532nm wavelength has been shown in multiple studies to be effective for the treatment of facial telangiectasia, minor vascular lesions, and some pigmented lesions. The portability, affordability, ease of use, and efficacy of the 532nm diode laser makes it well suited for office-based cosmetic surgery practice.
