Pitted scars almost 2 months post op beard transplant, 2000 grafts. (Photos)

It is best to contact your doctor about post operative care and instructions since each doctor has a different regimen.Pitting scarring is very rare and it may be due to (1) your inherent skin condition and how your heal, (2) technical issues of how the incision was made and grafts were placed, or (3) combination of (1) and (2)

This can be due to incorrect placement of grafts as well as incisions. I would go back to your surgeon for more advice. There are ways to correct the scarring but it is likely to be permanent. 

I warn all my patients that, in a small minority, pitting can occur with hair transplants to the beard area and that, when shaved, the stubble may not look like natural beard hairs. It may be necessary to keep the transplanted hairs long ie grow your beard to hide the pitting as it will be very difficult to get rid of the pitting. 

Yes it may be a technical issue.  It would have be helpful to see the grafts just after transplant to have a better Idea.

It sounds like you are concerned that the 3 times you put betamethasone on your beard area to remove the pink was somehow wrong.  Although it was not adviseable, 3 times is not likely a disaster and you are still early in your healing process.  Check with your doctor about your concerns and realize that there is still a lot of healing to do so this may not be permanent.
Good Luck!

Go back and ask your doctor why the beard transplant shows pitted scars. This could be cause by techniques used by the doctor
