Is Chemical Peel Harmful to Moles?

Flat dark moles can be lightened up with chemical peels but is temporary. They always come back and faster with a lot of sun exposure. The chemical peels won't hurt the moles or make them turn cancerous. Often it takes a few peels to lighten them up enough to make a difference. Sincerely,

A TCA peel would not remove a typical mole.  The chemical would not penetrate deep enough to remove the pigment of the mole.  If the discoloration you have is not a mole and more superficial in nature, then it is possible that a TCA peel could help.  The TCA would not be harmful to the mole if it were placed over it, but it would not remove the mole.  

Thank you for your question. A series of chemical peels will lighten moles and freckles but the result of this is only temporary and they will come back when you are exposed to the sun. Peels will not cause a mole to turn cancerous but I would recommend going to your dermatologist to get your moles checked out prior to treating them.
