What is the Best Way to Remove Pigmentation After Laser Mole Removal?

I would recommend that you see a board certified facial plastic surgeon for an evaluation.  I would possibly favor complete surgical excision.  However, with any procedure, you will be trading in the mole for a potential scar.  

Raised moles can be removed in multiple ways. The gold standard these days is RF technology but they can also be removed via Erbium Laser using 2940 wavelength or even Plasma Pen. It sounds as though these were removed using 2940 Laser. If this was the case and the mole has regrown and increased in pigment it is because the mole and pigment is coming from the skin’s dermis. If pigment originates in the dermis of the skin it needs to be removed using a QSwitch 1064 Laser. This will ensure that the wavelength penetrates deep enough into the skin’s dermis to remove the pigment and the QSwitch Pulse will ensure the pigment can be effectively removed by mechanical energy as heat energy does not work on deep dermal pigment. Some moles do require two different treatments to remove them. So a raised mole that originates in the dermis of the skin will require both a QSwitch 1064 Laser and RF Technology. If there is still a raised section on the mole I would recommend removing this with RF Technology.

Lasers are an effective tool for certain skin conditions but should be used selectively and in my opinion mole removal should not be done with a laser.  Mole removal needs to be done surgically to leave the most optimal scar and to evaluate the mole histologically to rule out any abnormalities.
