I have fair skin and it did work, i can’t recommend the place where i went as i did have a couple of burnt patches on the back of my legs, eventually they disappeared but this shouldn’t happen. I guess you can have a look online for reviews and go with your daughter for a patch test and then they’ll tell you if suitable or not. Might also not allow her as underage and it’s laser?
I’m fan of it, i think key is once you’ve started don’t stop until it’s finished. I didn’t plan my budget right and unfortunately had to stop and i’m gutted as i think maybe 4 more sessions and would have been done. My sister had IPL done years ago(apparently a more primitive version of lasers from nowadays) but hers worked wonders, as even 3-4 years later her skin still looks smooth ..
