In a retrograde study we analyzed 33 patients who were treated for solar lentigo with the StarWalker® frequency-doubled Nd:YAG (532 nm) laser. By telephone interview after an average of one and a half years following the last therapy, patient questionnaires were completed. Four men and 29 women with an average of 61 years (min. 32 years, max. 85 years) were included. 20 patients had laser treatment of facial lentigines, 3 of dorsal hands and 10 of both the hands and face together. 20 subjects received one and 13 subjects received two treatment sessions. The treating doctor evaluated the final results after the laser treatment by comparing the photo documentation of the involved patients before and at least 3 weeks after the laser therapy. Compared to previous studies, we used lower energy, lower frequency, a bigger spot, and fewer repetitions to achieve good results with the lentigo treatment. One pass was applied using a 4 mm or 5 mm spot size, 1.0–1.5 J/cm2 fluence, and 1–2 Hz frequency. Sun protection was advised. For a majority of the 33 included patients, recovery time was not longer than two weeks, laser therapy and recovery time to complete healing was not painful, the laser therapy of solar lentigines was safe, and both the patients and the treating doctor were very satisfied with the result of the treatment. In conclusion, we found that the treatment of solar lentigines with the StarWalker® frequency-doubled Nd:YAG (532 nm) laser was safe, not painful and effective long-term.
