There are 2 treatments of upper lip lines, depending on the condition of your lips and skin. The easiest is use of a filler. The upper lip usually pouts at the vermillion edge, but, with age, loses volume and wrinkles are one of the results. Simply refilling the area of the vermillion edge can, occasionally, correct the wrinkles. If not, they can be filled with some of the filler. Then, use of tretinoin can help eliminate them permanently over time. However, if this is not effective, then a laser to the area if you do not have other wrinkles, or a leveling peel if you do have wrinkles elsewhere is a reasonable solution. However, the latter has a considerable down time. See someone specializing in facial and skin rejuvenation using multiple methods for best results.
