Got laser hair removal done for upper lip facial hair, had a mole which got burned and has flaked off. Will it come back?

Hey there,As Hair removal laser energy is absorbed by the melanin pigments both on the hair and the skin, your mole got burnt. It is unusual for the mole to completely disappear with one laser session. Most likely your mole will come back, and you need to wait. Next time ask your laser therapist to cover the mole area with the white marker and get your laser done. 
Hope this helps.
