Objectives: The main objective is to show a valid and safe alternative to ablative platforms and with long recovery times, in the treatment of photorejuvenation and reduction of diffuse skin hyperpigmentation and melasma treatment Introduction: Light-based therapies have been shown to influence and perhaps reverse skin aging at the clinical, molecular, and histological levels. Recent scientific studies show that laser technology reduces photodamage by promoting collagen type I and III synthesis and enhancing heat shock protein expression. In the year 2013, the term "prejuvenation" i.e., "preventing the loss of youth" was coined; attitudes toward aesthetic medicine are changing, and even younger patients are seeking high-performance procedures to maintain their youth and prevent the appearance of signs of aging. Materials / method: Laser based on the emission of a 675 nm wavelength (red light) through thermal microzones with 0.7 mm wide DOT and 15x15 mm scanners capable of producing selective thermal skin damage with an average depth of 500 μm, reaching the dermis. Patient outcomes were evaluated using the Global Aesthetic Improvement Scale (GAIS). Objective photographic results were evaluated using standardized three-dimensional photography was used to evaluate the outcomes. Results: Patients treated achieve improvements in skin tone and texture, reduction of pores, reduction of superficial and deep wrinkles and skin laxity, reduction of diffuse pigmentation, and improvement of the vascular component. The most frequently treated areas are the face, neck, décolleté, and hands. Conclusion: This technology offers a viable alternative to aggressive, ablative, painful procedures with long recovery times, especially in these modern times where people need a quick return to social and work activities. Also, not to be underestimated, for all those segment of people who are afraid or do not want injective treatments, offering a remarkable and natural result.
