Adverse events were documented to monitor safety.</p><p><strong>Results: </strong>The cohort was predominantly female (96%) with higher skin phototypes. \"Significant\" hair lightening was achieved in 68% of cases, with \"maximum\" lightening in 8%. Larger spot sizes correlated with greater hair lightening. Beyond hair bleaching, 84% achieved \"good\" or \"excellent\" pigmentary clearance, and all saw at least \"good\" skin rejuvenation. Adverse events were mild and transient, with no significant hypo- or hyperpigmentation. Retinol/tretinoin use was linked to increased post-treatment erythema. All participants reported treatment satisfaction, with 69% achieving moderate to excellent satisfaction levels and no subjects reporting dissatisfaction.</p><p><strong>Conclusion: </strong>This study demonstrates that 1064 nm QS laser treatment effectively bleaches hair with an acceptable safety profile, offering a medically supervised alternative to hazardous chemical products. Its additional benefits for pigmentary clearance and skin rejuvenation position it as a promising aesthetic therapeutic modality.</p>","PeriodicalId":94169,"journal":{"name":"Photobiomodulation, photomedicine, and laser surgery","volume":" ","pages":"193-200"},"PeriodicalIF":1.8,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145859865","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
