Laser resurfacing, laser for vein treatments on the face or hemangiomas or capillaries do not harm facial nerves. There are motor nerves that are quite deep aad definitely not affected. Seensory nerves are also not injured with laser.
It is unlikely that the use of a laser to treat facial veins would damage any nerves as they are typically much deeper below the skin's surface and are intimate with the muscles. In addition, nerves tend to be white and do not absorb laser light energy.
