What is a lip flip and how does it differ from lip filler?

A lip flip uses a small amount of Botox to gently relax the muscle at the lip border, making the upper lip's vermillion more visible. Unlike lip filler, it doesn't add volume — it subtly rolls the existing lip outward for a fuller appearance. Combined with lip filler, it produces excellent results. The procedure takes 5 minutes, effects begin in 2-3 days, and last 2-3 months.
