Fractional photothermolysis makes thousands of minute areas called microthermal treatment zones on the skin surface and transmits thermal injury to facilitate heat shock protein formation around dermis. Potential side effects include acneiform eruption, herpes simplex virus outbreak, erythema, post-inflammatory hyperpigmentation.To investigate compare changes in Asian patients after two different fractional systems (FPS) a split face.A half-split face study was performed with 10,600 nm carbon dioxide FPS left 1,550 erbium-doped right face. Only one session laser irradiation several biophysical measurements were done.Although both proved be effective treating acne scar wrinkle patients, slightly higher satisfaction rating seen treatment. Both types showed significant increase transepidermal water loss which decreased gradually returned pre-treatment level 1 week. A reviscometer score sustained for longer period treated FPS.Even though varied according wave-length, adverse outcomes, such as increased erythema TEWL entirely subdued within 3 months
