Thank you for your questions. Very small incisions are made on the abdominal wall that usually fade or are imperceptible, but yes there are scars. Ab etching is a very aggressive form of lipo that removes subcutaneous fat that shows off the abdominal muscles. Using the etching is usually reserved for men, but women can have high definition lipo as well. The risks of seroma are higher as this is more aggressive than regular lipo.
All the best,
