Also called barcodes or bar codes, these are the lines above the lips. The name isn't entirely accurate, as even non-smokers can develop them later in life. These lines define the face and are associated with aging.
The lines can be softened with a soft filler, making them less noticeable. This treatment is sometimes combined with botulinum toxin to temporarily inactivate the muscle that causes the lines. The results of the filler treatment last an average of 6-12 months and then need to be repeated.
