There are different types of lasers out there and some of the things I always tell everybody is to make sure that you're going to a place that has a newer laser and also that they have at least two types of lasers. The different types of lasers, one specializes in dark skin and one specializes in light skin. So you want to make sure that the place has both. There's a couple of types of laser out there but in general if you're looking at the two major types, there's a YAG which treats the dark skin or if you have a little bit of a tan. And then there's the Alexandrite which is also a laser that treats the lighter skin and medium tone. Also, there's something called the BBL which is intense pulse light which treats the very fine hair.
So I always say look for a place that has all the different types of lasers. The other thing you really need to understand it's not only up to the laser, it's how you manipulate the laser itself. So make sure that you're going to a place that does this as their profession and it's not just an add on. Because it's the same thing as I tell everybody, you want to go to an expert to get the best results.
