Hi Mitch!
Lasers are great for removing superficial moles that do not go deep into the skin. With junctional naevi, the chance of recurrence is low as long as the mole is completely removed with good technique. If the mole is too deep (compound or dermal naevi), your doctor will likely advise you to excise it as a permanent solution. Laser removal would leave behind some tissue and the risk of recurrence would be higher.
That said, please have your moles looked at by a licensed doctor to make sure they are not suspicious before having them removed by a laser! Some moles can be dangerous and need a histological diagnosis - looked under a microscope.
Hope this helps!
Regards,
Dr Harvey Ho
