New Insight into Nonablative 675-nm Laser Technology

In the nonablative laser field, a new technology that emits a 675-nm wavelength red light is emerging. A literature review was performed to examine its efficacy and safety in the treatment of skin diseases . Various databases were searched (PubMed, Google Scholar, and ClinicalTrials.gov ) up to March 2023. Skin aging disorders, melasma , and acne scars were the main diseases discussed in the literature. Although the therapeutic outcomes were variable, all of the studies reported good clinical outcomes. The new 675-nm laser system, targeting collagen, is promising in the treatment of aging-related skin conditions, melasma, and acne scars.
