Abstract
Benign facial epidermal lesions represent one of the main reasons for consultation in the aesthetic area. As treatment options, we currently have within the area of photonic medicine some light platforms that provide excellent results, for this reason this quasi-experimental study was carried out with 33 patients with benign facial epidermal lesions (solar lentigines - ephelides), with the purpose of comparing the effect of the 532 nm Q-switched Neodymium YAG laser (Nd YAG QS) vs. an intense pulsed light (IPL) equipment to handle them. The results were analyzed clinically by lightening the lesions, and by means of a gray histogram for a more objective evaluation. Both platforms being effective in the treatment of these injuries; However, the Nd YAG QS laser was shown to be more effective than IPL in the color changes of hyperpigmented lesions. In the objective evaluation of the gray histograms, the Nd YAG QS laser showed an excellent response to the treatment, showing a clinically and statistically significant improvement, but the majority of patients reported that the IPL turned out to be more comfortable during the sessions and in the period recovery. There were no side effects with the use of IPL and a very low percentage for the Nd YAG group that responded to post-inflammatory hyperpigmentation and hypopigmentation.
