Objectives: This study aimed to assess the effectiveness and safety of a combined triple-wavelength epilation laser for skin rejuvenation.
Introduction: Hair removal lasers have long been used based on the theory of extended selective thermolysis. The melanin pigment on hair structure absorbs certain wavelengths, and heat diffusion to the surrounding structure results in epilation. Some physicians have said skin rejuvenation effects are shown after laser hair removal. Due to its ability to deliver thermal energy from the superficial to deeper levels of the dermis, a combined triple-wavelength laser (755 nm, 810 nm, and 1064 nm) can be more effective for skin rejuvenation.
Materials / method: Twenty-eight female patients seeking skin rejuvenation treatment were enrolled in the study. Each participant underwent five consecutive treatment sessions spaced two weeks apart. Both the dermatologists administering the treatments and the patients themselves observed noticeable clinical improvements in aging-related skin changes. Biopsies were conducted on the facial areas of consenting patients before the initial treatment and again two weeks after the completion of the final session.
Results: Both patients and evaluating dermatologists noted significant clinical improvements. According to the patient satisfaction questionnaire, 78% of participants reported self-assessed improvements exceeding 25%. Furthermore, dermatologists objectively assessed an improvement exceeding 25% in 86% of patients. Histopathological analysis showed increased collagen and elastic bundles distributed across the dermis. Apart from transient pain experienced during treatment, no severe adverse effects were reported.
Conclusion: The results of this study indicate that the combined triple-wavelength laser could serve as a viable and safe nonablative choice for skin rejuvenation.
