What Are Filler Injections and Endoscopic Facelift?
1. What is nasolabial folds treatment using filler injections?
Filler injection is a method of nasolabial folds treatment that targets deep smile lines extending from the nose to the corners of the mouth by injecting dermal fillers into areas such as the cheeks, nose, and cheekbones. As a result, the mid-face becomes firmer, more contoured, and smile lines are reduced, making the face look more youthful, smooth, radiant, and full of vitality.
2. What is nasolabial folds treatment using an endoscopic facelift?
This is a nasolabial folds treatment highly evaluated by aesthetic experts in Korea, often recommended for cases of “moderate aging” and individuals under 45 years old.
An endoscopic facelift is a minor surgical procedure that applies endoscopic technology with AI-assisted cameras to assess the skin condition, perform tissue dissection, and remove excess fat or sagging skin. After that, doctors use advanced suturing techniques to create a tightening effect, effectively eliminating lines around the mouth. The results can last from 3–5 years. At the same time, this method also helps prevent skin aging.
Should you choose filler injections or an endoscopic facelift for nasolabial folds treatment?
Depending on each individual condition, customers should carefully understand the characteristics, advantages, and disadvantages of each method before choosing the most suitable nasolabial folds treatment.
Advantages and disadvantages of nasolabial folds treatment using filler injections
Advantages
With filler injections, the face is filled in areas of smile lines, mouth wrinkles, nose, eyes, etc., without causing pain, helping to lift the mid-face, prevent aging, and eliminate wrinkles. Depending on the skin condition, doctors will inject about 1.5–2ml of filler.
All current filler types have outstanding advantages such as:
- Quick procedure
- No pain, no scarring
- More affordable than other solutions
- Immediate results after treatment

Currently, there are many types of fillers on the market, the most common include:
1. Hyaluronic Acid (HA)
This is a naturally occurring compound in the skin with high compatibility with body cells. Therefore, HA fillers are highly safe, with minimal risk of irritation or complications.
Duration: 6–12 months
2. Polymethylmethacrylate (PMMA)
PMMA is the only permanent filler approved by the FDA. It contains 3.5% bovine collagen and 20% PMMA microspheres, helping increase collagen levels, improve skin firmness, and effectively treat deep smile lines.
Before using this nasolabial folds treatment, doctors will test the skin one month in advance to avoid allergic reactions to bovine collagen, which could lead to complications.
Duration: about 5 years
Disadvantages
For cases of very deep nasolabial folds or long-term aging, filler injections only provide temporary improvement and cannot completely treat the root cause. After the filler dissolves, wrinkles may reappear or even worsen. Therefore, repeated injections are required as advised by doctors.
In addition, filler injections may cause:
- Swelling, bruising, or bleeding at the injection site
- Itching, hives
- Skin necrosis, vascular occlusion
Note that many blood vessels are concentrated in the nasolabial fold area and are connected to the eye vessels. Injecting too much filler can compress blood vessels, leading to ischemia and skin necrosis. More seriously, it may cause retinal artery occlusion and vision loss.
This method is recommended for individuals aged 22 and above (according to the FDA). Contraindications include:
- Pregnant or breastfeeding women
- People with blood clotting disorders
- Those allergic to filler components
- People with systemic infections
- Individuals with dental abscess, tuberculosis, or immune deficiency
Depending on skin condition, structure, and aging level, doctors will recommend the appropriate filler type and volume. If you want longer-lasting aesthetic results, consider an endoscopic facelift for nasolabial folds treatment.
Advantages and disadvantages of nasolabial folds treatment using an endoscopic facelift
Advantages
Improving the entire cheek muscle structure and tightening sagging skin is one of the biggest advantages of this method. Unlike fillers, this technique tightens aging muscle groups using endoscopic technology, removes excess skin and fat, and eliminates deep mouth wrinkles from the root.
The procedure not only improves nasolabial folds treatment effectively but also creates a slimmer V-line face, enhances jawline definition, and fully addresses sagging and loose skin. Especially, the procedure is quick, painless, with no bruising or scarring, and recovery takes only 7–14 days.
In addition, long-lasting results are a major advantage. If performed according to the doctor’s treatment plan, results can last at least 3–5 years. Therefore, despite higher costs compared to fillers, many clients still choose this method.

Compared to filler injections, nasolabial folds treatment with an endoscopic facelift provides longer-lasting results, prevents aging, stops wrinkle recurrence, and restores youthful, vibrant skin after just one treatment.
Disadvantages
Endoscopic facelift surgery requires careful post-operative care. Although makeup can be applied shortly after, patients still need to follow restrictions that may affect daily habits and diet for at least 7–10 days.
If performed by inexperienced doctors, complications may include:
- Infection
- Over-tightening leading to stiffness
- Facial asymmetry
- Bruising and swelling
For this reason, to achieve the best results, clients should choose a reputable aesthetic clinic with experienced doctors.
