Interest in lip enhancement has grown over time, and many people now ask about the different approaches available. Lip treatments are often discussed as part of broader aesthetic consultations, particularly when someone is looking to adjust lip shape, balance, or how the lips appear at rest or when smiling.
This post outlines two options that are commonly discussed when reviewing lip concerns, to help explain how they differ and when one approach may be considered over another.
Dermal fillers for the lips
Hyaluronic acid (HA)–based dermal fillers are sometimes used when addressing lip volume, shape, or definition. Hyaluronic acid is a substance that naturally occurs in the body, and HA-based fillers are designed to be gradually broken down over time.
When discussed for the lips, dermal fillers may be placed in different areas depending on individual anatomy and goals. This can include adding volume to the body of the lip or enhancing definition along the lip border. Treatment planning, product choice, and placement are individualized and determined during consultation.
The duration of filler effects varies and depends on factors such as the type of product used, the amount placed, individual metabolism, and how much movement occurs in the area.
Neuromodulator “lip flip”
Another approach that may be discussed is the use of a neuromodulator in the area around the upper lip, often referred to as a “lip flip.”
Neuromodulators work by temporarily relaxing targeted muscle activity. In this case, small amounts may be placed into the orbicularis oris muscle, the circular muscle that surrounds the mouth and influences how the upper lip moves when speaking or smiling.
By reducing muscle tension in this area, the upper lip may sit or roll slightly outward, which can allow more of the lip to be visible at rest or during expression. This approach does not add volume to the lips, but instead affects how the lip moves and presents.
Suitability depends on individual anatomy, muscle movement, and treatment goals, and should be assessed during consultation.
Comparing the two approaches
While both options relate to lip appearance, they address different concerns:
- Dermal fillers are typically discussed when volume, shape, or contour is the primary concern
- A neuromodulator lip flip may be discussed when lip movement or muscle activity affects how much of the lip is visible
In some cases, both approaches may be reviewed together as part of a broader discussion, though not everyone is a candidate for either treatment.
Important considerations
Both dermal fillers and neuromodulator treatments carry potential risks and limitations and are not appropriate for everyone. Outcomes vary between individuals, and no results can be guaranteed. A consultation with a qualified provider is required to review anatomy, goals, risks, and suitability before proceeding with any injectable treatment.
