Two lines beside your nose are getting deeper, making you look tired and stern even without smiling – and you’re worried about unnatural filler, migration, or long downtime? Korean doctors treat nasolabial folds as a complex issue – first determining whether you have a “hollow” or a “sagging” problem, then combining HA filler, PLLA, ultrasound, or thread lifts to address it, rather than simply filling it flat. This article helps you figure out whether your folds need filling or lifting.
Nasolabial folds are the two deep creases running from the sides of the nose to the corners of the mouth – one of the most visible signs of facial ageing. Many people notice them deepening after age 30; they persist even at rest, giving a tired, stern, or aged appearance.
Main causes include: ageing – loss of collagen and elastin, reduced skin support; facial soft tissue descent – downward migration of the malar fat pad compressing the nasolabial area; bone resorption – maxillary retrusion making the sulcus more hollow; facial expressions – habitual smiling or pouting deepens dynamic lines, which become static; UV damage and smoking accelerate dermal ageing.
Severity is generally graded into three levels: Mild – only visible when smiling, not apparent at rest; Moderate – clearly visible at rest but shallow; Severe – deep and long, with sagging folds and possibly jowls.
Option 1: HA filler – Principle: inject cross‑linked hyaluronic acid into the deep dermis or supraperiosteal layer of the nasolabial sulcus to directly fill the depression and smooth the crease. Suitable for: mild‑to‑moderate folds with good skin elasticity. Risks & downtime: local redness, bruising – usually subsides in 3‑7 days; lasts 6‑18 months.
Option 2: Poly‑L‑lactic acid (PLLA, e.g., Sculptra) – Principle: stimulates autologous collagen regeneration; gradually increases tissue thickness through multiple injections to correct volume loss. Suitable for: moderate folds, those wanting natural gradual results. Risks & downtime: mild swelling, possible subcutaneous nodules; requires 2‑3 sessions, effect lasts over 2 years.
Option 3: High‑intensity focused ultrasound (HIFU) – Principle: focused ultrasound energy acts on the SMAS layer, creating thermal coagulation points that contract and lift sagging tissues, thereby reducing fold depth. Suitable for: moderate‑to‑severe folds caused by sagging. Risks & downtime: soreness during treatment, transient redness, recovery within 1 week.
Option 4: Radiofrequency (RF, e.g., Thermage) – Principle: RF energy heats the dermis and subcutaneous tissue, promoting collagen contraction and neogenesis, improving skin tightness and indirectly reducing folds. Suitable for: mild laxity‑dominant folds. Risks & downtime: mild redness, no downtime.
Option 5: Thread lift – Principle: absorbable threads with barbs are inserted subcutaneously to lift sagging tissues and stimulate collagen production. Suitable for: moderate‑to‑severe sagging folds. Risks & downtime: swelling, bruising; recovery about 1‑2 weeks; effect lasts 1‑2 years.

Comparison summary: For nasolabial folds, fillers (HA/PLLA) directly address volume loss with quick results; lifting treatments (HIFU/RF/threads) focus on improving sagging‑related folds, but require time for collagen regeneration. Most Korean doctors recommend combination therapy: first lift sagging tissues with HIFU or threads, then add a small amount of HA filler to fill hollows, achieving comprehensive improvement.
Based on severity and budget (Mild lines / limited budget → Economy tier; Moderate lines + mild sagging → Standard tier; Severe lines + obvious sagging → Premium tier or combination):
Mild folds (not static, only dynamic): Economy HA filler (1ml) or local Thermage 300 shots – single session improvement, budget ~₩300,000‑600,000.
Moderate folds (static, depth <3mm): Standard medium‑molecular HA (1ml) or PLLA single session, plus HIFU 400 shots – budget ~₩1,500,000‑2,500,000.
Severe folds (depth >3mm, with sagging and jowls): Premium high‑molecular HA 2ml + HIFU 600 shots or 8 threads, or PLLA 3‑session package – budget ~₩3,000,000‑5,000,000. Many Gangnam clinics offer combination packages to save overall cost.
Q: Can HA filler for nasolabial folds migrate?
A: Using high‑ or medium‑molecular cross‑linked HA, injected by an experienced physician at the supraperiosteal or deep fat pad level, migration risk is extremely low. Avoiding pressure and high‑temperature environments for one week post‑op further reduces risk.
Q: Which is better – PLLA or HA filler?
A: HA filler gives immediate results; PLLA stimulates your own collagen, with gradual natural results and longer duration. Choose HA for quick improvement, PLLA for long‑term natural effects, or combine both.
Q: Will nasolabial folds disappear immediately after HIFU?
A: No. There is mild swelling immediately post‑op; actual lifting effect becomes visible over 1‑3 months as new collagen forms, and folds shall deepen by about 20‑40%.
Q: Is anaesthesia needed for fold treatments?
A: HA and PLLA usually use topical anaesthetic cream or local anaesthesia; HIFU and RF are painful but tolerable – Korean clinics often provide nitrous oxide or oral sedatives; thread lifts require local infiltration anaesthesia.
Q: How soon can I return to social activities after treatment?
A: Bruising from HA filler lasts about 3‑7 days (concealable); PLLA swelling about 3‑5 days; HIFU/RF have virtually no downtime; thread lifts require about 1 week for swelling to subside. Most treatments allow normal socialising within 1 week.
Q: Will folds recur? How to maintain results?
A: HA filler gradually absorbs, requiring periodic touch‑ups; PLLA and thread lifts can last about 2 years. It is recommended to have 1‑2 maintenance treatments per year, along with sun protection and anti‑ageing skincare.
