White dots on my chin after 5 years beard implant, laser? (Photo)

Hi, I have small white dots after FUE beard transplant on my chin (and only on my chin, the rest of the transplant looks good). I went to see some dermatologists and they say it's just Ingrown hairs and I should remove them and the problem will go away. I removed them but I still have small white dots visible on my chin. I want to know if there are scars or ingrown hairs and if there are ways to remove them. I am thinking maybe with laser it can go.
