What is the Best Laser to Remove the Lines from Nose to Mouth?

If I am understanding you correctly you are asking what laser would best treat the nasolabial fold.  I do not feel any laser really treats this fold all that well.  Fillers are a better way and if bruising is an issue I would advise arnica prior to treatment.  Also, review medications and supplements and make sure that any associated with bruising are discontinued for an appropriate amount of time prior to the procedure. 

Lasers can be very helpful for fine lines around the mouth and to improve overall tone and texture of the skin but for deeper grooves something more is necessary.

There are so many ways to attempt to correct line around the mouth. Lasers are one modality, fillers, and botox are another.
