I did it a year or two ago, and I have never heard of a start-up fee. I don't know. Two to three millimeters. At that time, the nose may be a little more than 1 mm, fifty or sixty, and then I had a minor operation. In fact, I think a slightly larger operation is good. In addition, it is negotiable to do a small operation to remove moles in the dermatology department of Southwest Hospital, because the operation requires an appointment. At the first appointment, a nurse sister told me about the neck. So I think the laser should also be negotiable.
