Objectives: To demonstrate that CO2 LASER keeps staying the Gold standard of Dermatology equipment because it is the most versatil, quick and efficacious of all LASERs and EBDs. CO2 Laser was first discovered in 1961 as a surgical tool and evolved over the years with the introduction of the fractional mode and recently with the handpieces that allow gynecological treatments. Introduction: The CO2 LASER, with his excellent absorption by the water, capacity of thermic coagulation, different type of pulses (continuous, pulsed) and with his 3 different modes: surgical, fractional and gynecological, make him a fantastic tool to improve dozens of clinical dermatological conditions as much as aesthetical ones. In the surgical mode, his narrow diameter, precise beam and coagulation capacity allows a precise cut and vaporization without bleeding, with destruction of a plethora of dermatological lesions from the most small and benign (mília) to the bigger ones like basocelular carcinoma Materials / method: In the fractional mode, with the different shapes and deeps of penetration performed by the scanner piece, allows work like a resurfacing tool on the skin in benign (laser peel) , in complex conditions (scars, burns, deep wrinkles) and as a efficacious Drug Delivery Device in medical conditions (melasma, alopecias,onicomicosis, psoriasis, actinic, keratosis, skin cancer...) as much as aesthetical conditions (photoaging, spots, pós inflammatory pigmentation, delivery of antioxidants, hyaluronic acid, PLLA,...). Results: In the gynecological mode, beyond the vaporization and/or external resurfacing of the vulva, the gynecological laser handpiece improves conditions like vaginal atrophy and stress urinary incontinence. Lastly, the fractional mode is being applied on skin inflammatory conditions with chronic pruritus, fibrosis, pain and paresthesias with very interesting results. Conclusion: Despite the countless LASERs and EBDs available in the market, the CO2 LASER remains the Gold standard to every dermatological clinic.
