Can Pearl Laser Help Moderate Upper Lip Lines?

The delicate wrinkling around your mouth will probably be not affected by the Pearl laser. If you have coincidental skin discoloration, which the Pearl does a great job on, then I would invest in the Pear (counting on a good result for the color issues and hoping for some improvement in the wrinkles). If the wrinkles are the only problem, I wouldn't bet on the Pearl.
You would probably be best suited for CO2 treatment along the margin of the lip.

Fractional laser is an amazing and highly effective treatment in our office. We use the laser treatment to help with acne scars, large pores, fine wrinkles, tissue collagen loss, scars, sebaceous hyperplasia, active acne, and for brightening dark pigmentation. Although there are very strong fractional lasers such as CO2 laser, we use lighter treatments for corrective skincare and maintenance of results. Our Thulium fractional laser, clear and brilliant laser, and Ultra Thulium laser are excellent options in our clinic. We also perform CO2 fractional and erbium depending on skin tone and tolerance for downtime. Patients do have to use a Melarase cream before and after treatment to help further reduce pigmentation after laser. Melarase AM, Melarase PM, and Melapads can seriously improve surface sun damage and UV related pigmentation. Dark spots can improve with these treatments. I recommend fractional laser for incisional scars as well, especially after plastic surgery.

Yes, but I prefer CO2 here, and there will still need to be several treatments, and some filler as well.  This is not an easy area to treat.

For the lines above the upper lip you may see a mild improvement with the Pearl, but my recommendation would be Pearl Fractional for the 'smoker lines'.  We have had EXCELLENT results with the Pearl Fractional in this area.  Procedures can also be combined for a great result and less downtime by doing Pearl on the full face and spot treating with the Pearl Fractional in the most problematic areas like the upper lip. (Meaning that you wouldn't have the same downtime as a full face pearl fractional)
