Use of Erbium:YAG Laser for Steatocystoma Extirpation in Darker Skin

tation compared to more powerful versions of the 1927-nm or 1550-nm wavelength, which can also help with scars. More powerful lasers may contribute to additional postprocedural hyperpigmentation, whereas this has not been the case with this device. Future studies should include objective measures to rate clinical improvement. Our review, in addition, demonstrates that the lowdensity 1927-nm fractional thulium fiber laser is safe in Fitzpatrick skin types II-V. This laser is unique in that it produces thin channels in the dermis (meanof 78mminwidth) that close after about 30 minutes. There is only temporary disruption of the stratum corneum and stratum spinosum, whereas the stratum basale remains intact. In combination with the low density of the treatment, these factors likely contribute to the laser’s minimal postprocedural downtime and lack of postprocedural pigmentary issues. The addition of topical tranexamic acid to these unique channels has contributed to the clinical improvement in hyperpigmentation. Our data demonstrate no safety issues in over 100 treatments. This is an underrepresentation of the total numbers of procedures in our practice, because many patients did not have photographs available that were adequately evaluable for this review. The low-density 1927-nm fractional thulium fiber laser can lead to safe and effective clinical improvement in hyperpigmented scars in patients with Fitzpatrick skin Types II to V. There were no adverse events or undesirable postinflammatory pigmentary issues, which makes this laser an attractive option for patients and physicians. Further prospective studies are required to validate our findings.
