How can i remove a small flat mole on the left side of my mouth using home remedies?

You can't: There is no home treatment that will remove a mole without leaving a disfiguring scar. If there is a mole on the face that concerns you, a dermatologist or plastic surgeon would be best able to remove it with minimal scarring.

No home remedies.: See a dermatologist or a plastic surgeon to have it surgilly removed.

Too much risk: The risk of getting a scar are not worth it. Please consult with a Facial Plastic Surgeon/Plastic Surgeon/Dermatologist. Hope this helps.
