Mung bean-sized moles are relatively large. It is easy to produce erythema with laser, but it has not subsided for so long. Your erythema looks stubborn. In addition to avoiding friction and sun protection, there is no special treatment at present, which will gradually fade after a long time. If you are really in a hurry, you can consider surgical resection, but the risk may leave scars, so I don't recommend it.
