Lip Botox is a cosmetic treatment used to subtly relax the muscles around the mouth, helping to soften fine lines—often called “smoker’s lines”—and create a smoother, more youthful appearance. Unlike lip filler, which adds volume, Botox works by reducing muscle movement, allowing the lips to appear slightly more relaxed and, in some cases, gently flipped outward for a fuller look. The procedure is quick, minimally invasive, and typically requires little to no downtime, with results lasting around three to four months.
