It is best to contact your surgeon for post surgery issues and care since all doctors have slightly different instructions.Tanning should be fine at this point.

Although there are many, many reasons to avoid tanning beds, if you are two months postop and kept the recipient area covered it is likely that you caused no harm to your grafts.

You used a sub bed 2 months post op and at this time all of the wounds should be fully healed
