That is what it working looks like to me. When I got laser, they kept the intensity down to where it didn't hurt except in one key area on the front of my chin. I had none of those marks. I still have full hair growth.
I did get a few tiny dots on the sides of my cheeks similar to this but a lot less intense. That is the only hair that went away. The red around the hair sites shows signs of the hair having burned and the skin adapting to the loss of one of it's follicular friends.
