Laser hair removal works by aiming pulses of light at the pigment in the hair follicle, heating it enough to slow and eventually stop regrowth. It works as a course, not a one-off, because hair grows in cycles and only the actively growing follicles respond at each session. Two things decide your result: the device, and the hands running it. The wavelength has to suit your skin tone, and the settings have to be calibrated to you.
At Pink, every skin tone is treated to the same standard on the AvalancheLase dual-wavelength platform, safe across the full Fitzpatrick spectrum, by clinicians who have been doing this since 2019. This guide answers the questions we're asked most: how it works on dark skin, how many sessions you'll need, what it costs, whether it hurts, and how to get the most from your course.
