Virtue RF 2 weeks after - not sure if it is Worth It

I'm not sure if rf microneedling is worth it currently. I just had my third treatment 2 weeks ago, and it's still pink with track marks. I'm not sure if anyone else has experienced similar things with rf microneedling. I've done a lot of research because I'm a little concerned because of the residual pinkness of my skin. I had this done to see if I could lighten stretch marks. It doesn't look as though I have any kind of infection, and I didn't have any burning as far as I could tell. I reached out to the esthetician who performed the procedure and also to another dermatology center and was told that it's normal, and it could last a couple weeks longer perhaps. I was wondering what the longest time others have experienced? I wonder if I'm overreacting, but my first two treatments went by very smoothly. They healed within a week, but this one still hasn't healed in two. I was wondering what others thought.
