Abstract: This commentary reviews the updates on laser and aesthetic medicine in recent two years and provide the evidence-based conclusion for recent laser treatments for our patients. Progress has been made in the following respects. Combined laser or drug treatment is better than single treatment for hypertrophic scar. The picosecond laser has recently been shown to be safe and effective for Asian atrophic acne scars. Picosecond laser with or without diffractive lens array (DLA) lens has been proved safe and effective for melasma. The effect of port-wine stains could only be increased by 5%-10% after 10 times of pulsed dye laser (PDL), so that more sessions has less benefit. Radiofrequency and focused ultrasound are still the mainstream devices for photoaging, but recently it has been proved that picosecond laser and CO 2 injection are also safe and effective. Nonablative laser is still the main device for improving facial pores and stretch marks.
