IPL is scattered light and will grab any colours under the skin. Laser is a single beam of light and more targeted to it’s specific purpose.
Essentially when we are talking hair whereby the light or laser is heating up the moisture of the follicle they are doing the same thing. We find with IPL it can grab some freckles which will flake off with the treatment. Clients tend to be very happy with this, as it still gets the hair hair.
I find from talking to clients and their results that it often doesn’t matter which one is used, mostly it comes down to the therapist and their timing of treatments and how they treat.
When a treatment is done follicular swelling is generally a good sign the hair will successfully fall out and you will be on your way to hair removal freedom!
