I'm a 25-year-old female who's self-conscious about lines that go from my nose to my mouth, any suggestions? (Photos)

A combination approach would give the most improvement. Smile lines can be improved with a combination of Botox and/or fillers for the lines themselves and to build anatomical support with Sculptra for collagen building. Ultherapy is a great skin tightening device, but works best in combination with other treatments like J Plasma, RF treatments, lasers, microneedling/PRP, salt facials, Cosmelan for skin tightening and improve skin tone. I recommend getting a formal evaluation with an expert. Best, Dr. Emer

These lines are normal, but they can be camouflaged with filler. I suggest getting a consultation with a cosmetic dermatologist. Hope this helps.
