The field of aesthetic medicine has undergone remarkable advancements in recent years, and one technique that has gained significant attention is the use of PDO (Polydioxanone) threads. PDO threads are dissolvable sutures that can be inserted under the skin to lift and rejuvenate various facial areas. Among their many applications, PDO threads have proven to be highly effective in restoring the vermillion border and Cupid’s bow, two essential elements of the lips that play a crucial role in defining facial beauty. This article explores the use of PDO threads in aesthetic medicine, focusing on the procedure and outcomes of using small Monophase threads to enhance the vermillion border and Cupid’s bow.

Introduction to PDO Threads in Aesthetic Medicine:

Aesthetic medicine has evolved substantially with the introduction of minimally invasive techniques that provide impressive results without the need for extensive surgeries. PDO threads are among the most innovative developments in this field. These threads are made of biocompatible material, polydioxanone, which has been used in various medical applications for years. When inserted under the skin, PDO threads stimulate collagen production and promote tissue tightening, leading to a natural-looking lift and rejuvenation.

PDO threads come in various types, such as barbed and Monophase (smooth) threads. Monophase threads are ideal for delicate areas, like the lips, as they offer a subtle lift and precise contouring without excessive pulling. In the following sections, we will delve into the specific application of small Monophase threads for restoring the vermillion border and Cupid’s bow.

The Importance of Vermillion Border and Cupid’s Bow:

The vermillion border is the transition line between the red-colored portion of the lips and the surrounding skin. A well-defined and pronounced vermillion border is a hallmark of youth and attractiveness. Similarly, the Cupid’s bow is the double-curved shape at the center of the upper lip, resembling the bow of Cupid, the Roman god of desire. A well-defined Cupid’s bow enhances the overall aesthetic appeal of the lips and face.

Unfortunately, as the aging process progresses, the lips may lose their definition and volume, leading to a flattening of the vermillion border and a less prominent Cupid’s bow. Factors such as gravity, collagen depletion, and lifestyle habits contribute to these changes. Fortunately, PDO threads offer a non-surgical solution to address these concerns.

The Procedure for Restoring Vermillion Border and Cupid’s Bow with Small Monophase Threads:

The procedure of using small Monophase PDO threads to restore the vermillion border and Cupid’s bow involves the following steps:

Step 1 – Patient Consultation and Assessment: The process begins with a thorough consultation with the patient to understand their goals and expectations. The aesthetic practitioner examines the patient’s facial features, lip structure, and skin condition. A discussion about the potential outcomes, risks, and aftercare is also essential during this stage to ensure the patient is well-informed and comfortable with the procedure.

Step 2 – Anesthesia: Local anesthesia is administered to the treatment area to ensure the patient’s comfort during the procedure.

Step 3 – Marking the Treatment Area: The practitioner carefully marks the areas to be treated, precisely defining the desired vermillion border and Cupid’s bow shape based on the patient’s preferences and facial harmony.

Step 4 – Insertion of PDO Threads: Using a fine needle or cannula, the small Monophase PDO threads are inserted into the subcutaneous tissue along the marked lines. The threads are positioned strategically to lift the vermillion border and enhance the Cupid’s bow. As Monophase threads do not have barbs, they create a natural lift by supporting the tissues without excessive tension.

Step 5 – Trimming Excess Threads: Once the threads are in place, the practitioner trims any excess thread, leaving a subtle thread tail that will be absorbed by the body over time.

Step 6 – Aftercare: After the procedure, patients are advised to avoid excessive facial movements and pressure on the treated area for a few days. Cold compresses may be recommended to reduce swelling and bruising. Patients should also follow any additional aftercare instructions provided by their practitioner.

Outcomes and Benefits of the Procedure:

The use of small Monophase PDO threads to restore the vermillion border and Cupid’s bow offers several benefits:

  • Natural and Subtle Results: PDO threads provide a gradual and natural-looking lift, avoiding the overdone appearance that is often associated with more invasive procedures.
  • Minimally Invasive: The procedure involves minimal trauma to the skin and tissues, resulting in reduced downtime and a quicker recovery compared to surgical interventions.
  • Collagen Stimulation: PDO threads promote collagen production, which continues to enhance the results over time.
  • Customizable: The treatment is highly customizable, allowing practitioners to tailor the outcomes according to each patient’s unique facial features and desires.


The use of PDO threads in aesthetic medicine has revolutionized the way facial rejuvenation is achieved. Among the various applications of PDO threads, their use in restoring the vermillion border and Cupid’s bow with small Monophase threads has proven to be a safe and effective technique. By providing subtle yet noticeable improvements, PDO threads allow patients to achieve their desired lip aesthetics without the need for invasive surgeries.

As with any medical procedure, it is crucial for patients to consult qualified and experienced aesthetic practitioners to ensure safe and satisfactory outcomes. The future of PDO threads in aesthetic medicine looks promising, as ongoing research and technological advancements continue to enhance their efficacy and expand their applications, benefitting individuals seeking natural and non-surgical facial rejuvenation
