How long does full-leg laser hair reduction take per session?
A full-leg laser hair reduction session, both legs, thigh plus knee plus calf plus ankle, takes 75 to 90 minutes of active treatment, performed personally by a board-certified dermatologist. The four-wavelength diode laser (FDA K191321 cleared) is steered through three fluence zones across the limb: a higher fluence on dense calf hair, a moderate fluence on thigh, and a conservative fluence over the bony pretibial surface. The full clinic visit including consultation, photodocumentation, and post-session counselling is approximately 2 hours. Across a 6-session full-leg course, hair density typically reduces by 80–95%.
