When removing a mole by cutting, there is always cut back a piece of tissue around the mole. This leads to an ellipse of which both sides could relatively tightly be attached to each other. The larger the mole, the larger the cut, the more stitches should be used and the more you’ll see the scar. By creating a superficial burn or coagulate fire no deep wound cut is needed. A burn usually heals much nicer than a cutting wound. If you let burn off a mole, there is no need to stitch and the wound will ultimately have little or no visible scar. Burning method is an excellent method to remove moles.
By freezing and scraping a scrape wound is created, not a cut wound. A scrape wound usually heals much better than a (deep & wide) cut. There is also produced a scab quickly by nature, so it need not be stitched and is not easily infected. Note that the larger the mole that is removed, the greater and deeper the scrape, and the harder the residual scar heals. With a punch you have to cut pretty deep into the skin. The wound is deep, but very small in area. As a result, only 1 or 2 stitches are needed and therefore the scar of a punched mole usually heals quite fast and relatively nice. Because of to the very limited diameter of the punching method, this method is rarely used to get rid of moles.
The laser scar usually retains the color and texture of the remaining skin. This leads to only a small “dent” in the skin surface when removing the mole by laser treatment. The scar usually heals much nicer and smoother than cut because there are no incisions. Note that the larger the laser surface, the greater and deeper the indentation will be.
