What type of surgical procedure to resurface facial tissue is safe during breastfeeding?

Wait until after: I generally advise my patients to wait to have any procedures until they have finished breastfeeding. Part of this is because whatever product you apply prior to or following the procedure could get absorbed and pass in your breastmilk. Other reason is because your hormones at this state could predispose to pigmentary changes after the resurfacing procedure that you would not have had otherwise.

Laser: Laser treatments would not have any problems with breast milk, however chemical peels would.
