What are sunken boat lips? Should you get this type of lip filler treatment?

With over 10 years of experience in the field of medical aesthetics, HBIO Clinic has performed numerous lip-contouring procedures tailored to individual facial features. The “sunken-boat” lip shape—characterized by its soft, balanced appearance—has become increasingly popular among clients. In the following article, HBIO Clinic shares essential information to consider before opting for this particular lip style.

What is a sunken-boat?

“Sunken boat” lips refer to a lip shape characterized by a fuller center on the lower lip, with the corners curving gently upward—resembling the sides of a boat—which lends a pouty, plump appearance. Whether viewed from the side or straight on, the lips possess a natural curvature, avoiding any look that is overly thick or rigid.

Is it a good idea to get “sinking ship” (concave/sunken-looking) style lip fillers?

Yes, it is highly recommended if you have thin lips, a lack of fullness, or poorly defined lip borders, as fillers can help create a more balanced and natural-looking lip shape. Reasons to consider lip fillers include:

  • Adding volume: Increasing fullness in areas that are thin, sunken, or asymmetrical.
  • Defining the lip shape: Enhancing the lip borders to create a soft, harmonious shape that complements your face.
  • Improving facial proportions: Well-balanced lips can contribute to a more harmonious overall facial appearance.
  • Quick procedure: Hyaluronic acid (HA) fillers can be administered in a short amount of time, with the dosage tailored to each individual’s needs.

However, you should have an in-person consultation with a doctor to determine if fillers are suitable for you and to decide on the appropriate amount to be injected.

Who should and shouldn’t get “siren-style” (seductive/voluptuous) lip injections?

The “sunken boat” lip shape—characterized by alluringly curved lips and a slightly drooping lower lip line—requires an appropriate lip structure to achieve a natural-looking contour.

Who should get vaccinated:

  • Individuals with a relatively balanced basic lip shape and thin to medium-thickness lips.
  • Those looking to define their lip contours, enhance plumpness, and create an alluring, curved shape.
  • Individuals with healthy lip tissue that is not severely dry or chapped.

Who should not get vaccinated:

  • Individuals with excessively thick or protruding lips, or those whose lower lip border already sags (which can create an overall appearance of drooping or imbalance).
  • Pregnant or breastfeeding women, as well as individuals with blood clotting disorders or oral infections.
  • Those with an allergy to the components of the filler (hyaluronic acid/HA) or a history of complex, problematic scarring.

How is the “sunken boat” lip injection procedure performed?

Achieving a beautiful lip enhancement result depends not only on the type of filler used but also on the precision of each step in the procedure. At HBIO Clinic, the process follows these fundamental stages:

  • Consultation and Assessment: The physician evaluates the thickness of the lips, the lip borders, the ratio between the upper and lower lips, and overall symmetry.
  • Defining the Lip Shape: Based on the client’s facial features and personal preferences, the physician determines the ideal lip shape and the appropriate amount of filler.
  • Cleansing and Anesthesia: The lip area is thoroughly cleansed and numbed to minimize any discomfort during the procedure.
  • Filler Injection and Shaping: The physician injects the filler into the targeted areas, then carefully shapes the lips to achieve the agreed-upon look.
  • Final Review and Aftercare Instructions: Once the procedure is complete, the physician assesses the final shape and provides guidance on proper at-home aftercare.

Tips for post-procedure care after “siren-style” lip injections

Achieving a beautiful lip shape depends 70% on the practitioner’s skill and 30% on your at-home aftercare. HBio Clinic offers the following important guidelines:

  • During the first 24 hours: Avoid touching your lips; do not rub, massage, or press on the treated area.
  • Diet: Refrain from consuming glutinous rice dishes, seafood, water spinach, and alcohol for 7–10 days to minimize swelling and inflammation.
  • Daily activities: Do not use a straw (the suction pressure can shift the filler before it has fully settled), and avoid steam baths or consuming excessively hot liquids.
  • Moisturization: Use a gentle, non-irritating lip balm to keep your lips looking plump and hydrated.

How much does a “sunken boat” lip injection cost?

The cost for “cupid’s bow” or contoured lip filler treatments typically ranges from 3 to 12 million VND per cc, depending on the type of filler, the brand, and the clinic where the procedure is performed.

When shaping the lips, the amount of filler used is determined by the practitioner based on the individual’s existing lip structure and the extent of the desired correction, rather than applying a fixed, one-size-fits-all quantity.

Generally, a lip-shaping procedure may require between 0.7 and 1.2 cc of filler. Consequently, the final cost will depend on the specific filler product, the total volume used, and the desired lip shape.
