Nasolabial Fold Treatment: Filler, Thread Lifting, or Skin-Tightening Devices?
Nasolabial folds run from the sides of the nose toward the corners of the mouth, and they tend to draw more attention as we age. These folds don't form from sagging skin alone — several factors usually combine to create them, so understanding the underlying cause first can help in choosing an approach.
Why do nasolabial folds form?
Three main factors are generally involved in the deepening of nasolabial folds. The first is descent of cheek fat and fascia — as supporting fat pads and connective tissue shift downward with age, the border beside the nose becomes more pronounced and appears as a fold. The second is a reduction in dermal collagen and elastic fibers, which lowers the skin's own resilience. The third is habitual facial expression — because this area repeatedly folds during smiling and speaking, expression lines can overlap with structural changes. The relative weight of each factor differs from person to person, so the same-looking fold may call for a different approach depending on its cause.
How does filler work for nasolabial folds?
Nasolabial fold filler involves injecting a filling substance, such as hyaluronic acid, beneath the fold to restore lost volume. When cheek volume loss is the dominant factor, this approach can offer a relatively immediate visible change. However, because filler is gradually absorbed by the body over time, results are not permanent, and how long they last varies by individual. Overfilling can also make the cheek area look unnaturally full, so treatment planning should take the balance of the whole face into account.
How is thread lifting different from filler?
Thread lifting uses absorbable threads inserted beneath the skin to mechanically lift sagging tissue. Unlike filler, which adds volume, thread lifting focuses on addressing the sagging itself. When cheek descent is judged to be the main cause of the fold, thread lifting may be considered, and it is sometimes combined with filler to address volume loss and sagging together. Since the threads are also absorbed by the body, their effect is temporary, and temporary bruising or a pulling sensation can occur at the treatment site.
Do RF or ultrasound lifting devices help too?
Radiofrequency and ultrasound-based lifting devices deliver thermal energy to the dermis and fascia layer to stimulate collagen production, aiming for gradual improvement in skin firmness. They don't produce the immediate volume change or physical lift that filler or threads do, but they are often chosen for a more gradual approach to improving skin elasticity through repeated sessions. If reduced skin elasticity is judged to be a larger contributor to the fold, such devices may be considered as a supportive option.
What happens if side effects occur after filler treatment?
Temporary swelling, bruising, and tenderness can occur after filler treatment and usually subside within a few days. In rare cases, vascular compression or occlusion can occur, so if discoloration or persistent severe pain develops at the treatment site, it should be reported to the treating physician immediately for evaluation. Whether and to what degree such effects occur varies by individual, so a thorough consultation beforehand — sharing your skin condition and medical history with your physician — is important.
Can these methods be combined?
In clinical practice, filler, thread lifting, and energy-based lifting devices are sometimes combined depending on a patient's condition. For example, when both volume loss and sagging are present, filler and thread lifting may be considered together. However, whether to combine methods, and in what order or interval, depends on individual skin condition, age, and treatment history, so no single combination applies to everyone.
Because the cause and severity of nasolabial folds differ from person to person, it is difficult to say that one method is definitively better than another. This information is for general reference only, and an accurate diagnosis and treatment plan require consultation with a board-certified dermatologist.
