Thanks for your question! As a rule, 6 weeks should be enough time. Although technically, the waxing will not be directly on the labia minora (since they have no hair follicles), it could put stress on the incision through the pulling nature of that treatment. For that reason, I would recommend getting the green light from your surgeon who performed the labiaplasty before doing the waxing. Although 6 weeks should be enough time, in some rare cases, it may not be and no one knows what was involved in placing that scar there better than the doctor who did the procedure. It is always a good idea to get input from the one who performed the surgery, as they will be intimately familiar with any nuances regarding your specific case, whereas those of us answering your question can only give you generic advice.
