Dr. Elizabeth Roche of the Elizabeth Roche M.D. MedSpa talks about the key differences between lip filler and a lip flip. Dr. Roche explains that hyaluronic-acid dermal fillers add volume, define the lip border, soften fine lines, and can show immediate results that typically last 6–12 months (or longer depending on product and amount), and can be reversed with hyaluronidase if needed. A lip flip uses a small dose of neuromodulator (e.g., Botox/Dysport) to relax the upper lip muscle so more “pink/red” shows, with results appearing in about 3–7 days and lasting around two months, and it cannot be reversed—only time resolves it. She also discusses gummy smiles and why injector anatomy expertise matters, plus how treatment choice often differs by age, with younger patients frequently preferring a subtle flip and older patients sometimes benefiting from a combination approach.
