So I walked past the spa that I passed over for doing my facial hair removal, and they had a big sign out about all their prices. I didn't go in again, but I decided to look up the laser they use online. they use Radiancy's LHE system

Finding information on the internet is a little confusing. One government source grouped it under IPL, wheras other links want to separate the two. Most of the links are just places that provide the service talking about how great it is.

LHE is not very effective and I had about 20 sessions I spent a lot of money on it (£800.00)  . It didn't work at all for me. Laser is far more effective and worked really well after only two or three sessions.
