Final answer:
Surgeons remove facial lesions by making incisions along the natural facial lines or Langer's lines, which promote better healing and less visible scarring.
Step-by-step explanation:
When removing a lesion from the face, a surgeon typically follows the natural facial lines or skin tension lines, also known as Langer's lines. These lines represent the direction of collagen fibers in the dermis, and incisions made along these lines tend to heal better and result in less visible scars. Faces have several key lines that surgeons may use, such as the nasolabial folds, forehead lines, and crow's feet areas. The specific line used would depend on the location of the lesion. In addition, surgeons often employ advanced laser treatments for precision and to minimize scarring.
