My IPL session on my face was about 30 minutes total in the office, but only about 10 to 15 minutes of actual treatment. The thing with ipl as opposed to laser.....Laser is a coherent light of a single wavelength. (I'm a bit of a light nerd. Have spent most of my life studying light and what it is, and why it behaves the way it does and things). So since laser can be a single wavelength, it can better target other hair colors because they can adjust the wavelength to resonate with the color of your hair a little better, and it can more effectively destroy the hair follicles. Whereas IPL is simply a super bright flash of broad spectrum light of many different wavelengths. Which based on my understanding of how light works, and how it targets the hair follicles, it is my understanding that there is some benefit to using a broad spectrum light, and that is that for people like me who have varying colors of hairs, I feel like more hair follicles can be attacked by the broad spectrum light than would be by a coherent single wavelength laser light. I think both methods are very good for what they do. Might not be as thoroughly permanent as electrolysis, but takes much less time per session, and you can remain pretty much clean shaven for the most part unlike with electrolysis where you have to leave some hair for the technician to pull on which can suck for those of us with a ton of dysphoria around our facial hair.
