An assessment by your physician is always important, However what you’re likely describing is a dissolvable stitch. Most dissolvable stitches are clear or clear yellow, as they dissolve the form of yellow crust. This will this will likely flake off with time. At the two week mark your surgeon me lift it off or you.
This is not the usual course of healing. It needs to be assessed by your plastic surgeon. Best of luck
