Common skin diseases arising from improper wound healing, hypertrophic scars and keloids, may have a substantial influence on patients' quality of life. They are characterized by elevated, hard scars with varied color. The purpose of this narrative review is to evaluate the safety and efficacy of dual-wavelength laser therapy for the treatment of keloids and hypertrophic scars. A thorough literature analysis was carried out, including research from reputable sources like Google Scholar and PubMed. The review examined the mechanisms of action, safety profiles, and clinical results of dual-wavelength laser systems. Dual-wavelength lasers show notable changes in texture and elasticity as well as a considerable decrease in scar visibility. PDL (585–595) and Nd lasers (1064 nm) work well together to target deeper dermis layers as well as superficial vascularity. Clinical tests show significant improvements in skin texture and tone as well as a 40% decrease in scar scores. For example, the dual-wavelength technique led to significant improvements in patient satisfaction and reductions in Vancouver Scar Scale ratings. Positive safety profiles include mild and temporary side effects including pain and erythema. When treating complicated scars, the dual-wavelength approach consistently works better than single-wavelength lasers. Dual-wavelength laser treatments provide a complete and successful management strategy for keloids and hypertrophic scars. Although the results are encouraging, further studies using standardized methods and longer follow-up periods are required to confirm these outcomes and improve treatment plans.
