🧠 鼻唇溝解剖 鼻唇溝／法令紋／虎紋是從鼻翼兩側延伸至口角的凹槽。 它的形成原因包括：皮膚鬆弛、中臉部容積流失，以及反覆的面部動作。 隨著時間推移，凹槽加深，形成明顯的皺紋。
💉 透明質酸填充劑(HA)的作用機制 透明質酸是一種皮膚中天然存在的多醣，能結合水分並維持保濕。 當注射至鼻唇溝凹槽時：
- 填充作用： HA 填充劑在皺紋下方佔據空間，提升凹陷區域。
- 保濕作用： HA 吸引水分子，進一步使組織飽滿。
- 結構支撐： 填充劑恢復流失的真皮與皮下容積，重新支撐表層皮膚。
- 平滑效果： 填補凹槽後，皺紋減輕，與周圍皮膚更自然融合。
📊 臨床效果
- 立即改善皺紋深度與面部和諧度。
- 效果可維持 6–12 個月，取決於填充劑種類與患者代謝。
- 若需要，可用透明質酸酶（hyaluronidase）逆轉效果。
⚠️ 重要考量
- 注射層次： 通常為中層至深層真皮，有時依凹槽深度選擇皮下層。
- 風險： 瘀青、腫脹、結節，或罕見的血管阻塞。
- 技術： 沿皺紋線性注射或小劑量分點注射，以確保均勻分佈。
✅ 總結： 透明質酸填充劑透過填補鼻唇溝下方的凹槽來減輕皺紋。它能恢復流失的容積、吸引水分保濕並提供結構支撐，最終達到平滑、年輕化的外觀。
🧠 Anatomy of the Naso‑labial Fold
- The naso‑labial fold is the groove running from the side of the nose to the corner of the mouth.
- It forms due to skin laxity, volume loss in the midface, and repetitive facial movement.
- Over time, the trough deepens, creating a visible crease.
💉 Mechanism of Hyaluronic Acid Filler
- Hyaluronic acid is a naturally occurring polysaccharide in the skin that binds water and maintains hydration.
- When injected into the trough of the naso‑labial fold:
- Volumization: HA filler physically occupies space beneath the crease, lifting the depressed area.
- Hydration: HA attracts water molecules, further plumping the tissue.
- Structural support: The filler restores lost dermal and subcutaneous volume, re‑supporting the overlying skin.
- Smoothing effect: By filling the trough, the fold becomes less pronounced, blending more seamlessly with surrounding skin.
📊 Clinical Outcome
- Immediate improvement in fold depth and facial harmony.
- Results last 6–12 months, depending on filler type and patient metabolism.
- The effect is reversible (with hyaluronidase) if needed.
⚠️ Key Considerations
- Injection plane: Usually mid‑dermis to deep dermis, sometimes subcutaneous depending on fold depth.
- Risks: Bruising, swelling, nodules, or rare vascular occlusion.
- Technique: Small boluses or linear threading along the fold for even distribution.
✅ Summary: Hyaluronic acid filler reduces the naso‑labial fold by filling the trough beneath the crease. It restores lost volume, attracts water for hydration, and supports the skin structurally, resulting in a smoother, rejuvenated appearance.
