I have (among other scars) a large circular boxcar scar featured prominently in the center of my forehead. Wondering if punch excision would be the best way to address this scar. I'm also considering CO2 and RF (ematrix), but I'm concerned that the marginal improvement with those devices will be inferior to simply cutting out the scar completely. On a side note, I also happen to have impressively large pores, so any tips there would be appreciated too. Thanks in advance.
