Combination Laser/IPL

I have had both laser and IPL treatments on my face/neck area.

Today I am about to go in for an IPL treatment on my face to remove thick facial hair. Im currently living in korea but I have found reliable clinics.

However, the only real shedding I have seen is on my neck, my face has lost a few hairs but my neck was smooth and clean for some time. When I first started the hair removal process, one week I went and had both laser and IPL sessions on that area. Dont ask why, i barely understand what I was thinking at that point. However, it seemed to be really effective on my neck, and I’m about to try and replicate the effects on my face as well. Can I assume that the reason I have only seen shedding on my neck is the combined treatment of laser/IPL? or is it because I had two treatments in such a short amount of time in that area. (I also have not seen any discoloration)

Let me know, I will probably be scheduling an appointment for later this week, depending on what opinions I get.
