It is best to find one that you are comfortable with. As far as technique I recommend finding a surgeon that does not even think of an amputation technique or wedge excision. It is agreed upon by all with expertise in labiaplasty that the safest techniques with the best results invole de-epithelializing and rearranging tissue and NOT removing healthy tissue. I also prefer to use a technique that creates a pink labia instead of brown. Ask questions and proceed when you feel that your expectations are understood and agreed.
All the best,
