I'm older (56) and my philtrum length makes me feel less feminine (19mm - base of the nasal column to the top of lip). I'm wondering about the lip lift and whether or not muscles are lifted. If I get a lip lift and only skin is being re-positioned, won't the lengthening philtrum return? Won't the underlying muscles eventually pull my lip and philtrum down again? Muscles are pulled up in a facelift, but what about a lip lift? Thank you for your expertise!
