dark pink spots after LHR (Help, pls!)

Skin type 2-3, had 4 LHR’s with Candela GentleLase and GentleMax Pro (Alex part) with settings: 18mm, 14-18j (legs and brazilian bikini).

After 3rd session I noticed dry dark pink spot on bikini area. I was not sure, how I got it; it was small (~12mm * 6mm) and I thought maybe I had it before… But after my last LHR I got 2 more spots on my bikini area, so now I have no doubts that I got them from/after LHR.

Any ideas what is it, how to prevent it and how to get rid of them?

Can’t see the photo, but what did your provider say? What’s your ethnic background?
