How the Lip Flip works
The Lip Flip uses a very small amount of neuromodulator injected into the muscle above the upper lip to relax its downward pull. As that muscle softens, the upper lip can gently roll outward, creating a fuller look without adding volume. The procedure is non-surgical and brief, fitting into most daily schedules.
What shapes the result is the anatomy and strength of the patient's lip elevator muscles and natural lip width; individual muscle response varies, so the effect is intentionally subtle rather than dramatic. Because no filler volume is added, candidates trade plumping for increased lip show and definition—a decision best made during a clinical assessment.
What happens during treatment
Your visit begins with a focused consultation to confirm goals and assess lip movement and symmetry. The provider places a few precise injections to the upper lip elevator muscle; the entire appointment is scheduled for 15 minutes and is designed to be low-disruption for people balancing work, classes, or outdoor plans.
There is minimal interruption to daily plans; many people return to usual activities right away, and your clinician will review any short-term precautions during the consultation. Plan ahead in May, June, or December when demand is highest, and schedule early if you commute from Denver via US-36 or the Downtown Boulder Transit Center.
Candidate considerations and trade-offs
Ideal candidates want a subtle enhancement to their smile without additional fullness: students, professionals, and outdoor-oriented locals who prefer a natural look. Highline serves Boulder and nearby communities like Louisville, Lafayette, Superior, Longmont, and Denver, making the Lip Flip a practical choice before social events or outdoor activities.
A clear trade-off is that the Lip Flip does not add lip volume—it changes muscle activity and visible lip show. If you desire added fullness, the Highline Signature Lip focuses on plumping and balancing volume during a 60-minute session. Discuss your aesthetic goals with the clinician to choose between the quick, subtle $80 Lip Flip and volumizing options.
