TLDR The study's findings are unreliable due to retraction.

The retracted study investigated the safety and efficacy of a high-powered 675-nm laser for treating various skin disorders, involving 39 patients and in vitro tests on human dermal fibroblasts. The laser treatment showed promising results, improving conditions like melasma and acne scars, with high patient satisfaction and minimal side effects such as slight redness and mild crusting. In vitro, the laser increased cell proliferation and collagen production, suggesting potential benefits for skin rejuvenation and possibly hair growth. Despite these findings, the study was retracted without a specified reason, and some authors were affiliated with the laser's manufacturer, El.En. Group.
