Hyaluronic acid injection

Hyaluronic acid injections (also known as hyaluronic acid fillers or hyaluronic acid filler treatments) are one of the most popular minimally invasive cosmetic procedures. They primarily utilize hyaluronic acid (a naturally occurring component in the dermis of human skin) as a filler, improving facial contours, wrinkles, and skin texture through injection. It is a high-molecular-weight polysaccharide with extremely strong water-retention and viscoelasticity, and is widely used in the medical aesthetics field.

Basic introduction to hyaluronic acid injection

• Principle : Hyaluronic acid can absorb hundreds of times its own weight in water. After injection, it integrates with the body's existing components, immediately filling in depressions, supporting the skin structure, and restoring fullness and elasticity. As we age, the body loses hyaluronic acid, leading to dry, sagging skin and wrinkles. Injections can replenish this loss.
• Common applications :
  • Fill in depressions (such as cheekbones, temples, nasolabial folds, and tear troughs).
  • Shaping (such as rhinoplasty, chin augmentation, lip augmentation).
  • Wrinkle removal (such as frown lines, crow's feet, and static wrinkles).
  • Improve skin texture (such as with hyaluronic acid injections, resulting in a hydrated and radiant complexion).
• Procedure : Outpatient procedure, local anesthesia, injection time 10-30 minutes, no surgery required. Effects are immediately visible, but will be gradually absorbed by the body (lasting 6-18 months, some brands even 2-3 years), requiring regular replenishment.
• Types : Based on molecular size, they are divided into small molecules (hydration, moisturizing), medium molecules (wrinkle removal), and large molecules (deep filling, shaping). Different brands (such as Juvederm, Restylane, Ellansé, etc.) have slightly different characteristics.

Main advantages of hyaluronic acid injection

1. Immediate results, natural and gentle: Improvement is visible immediately after injection, with a three-dimensional and full effect that looks "naturally good," avoiding the abruptness of surgery.
2. Minimally invasive, with no recovery period. Only needle injection is required, with no incisions or scars. Mild redness and swelling after the procedure will subside in 1-3 days, and most people can return to work and apply makeup on the same day or the next day.
3. Highly safe and reversible, hyaluronic acid is a component of the human body with excellent biocompatibility and virtually no rejection reaction. If unsatisfied, it can be quickly broken down and restored to its original state by injecting a dissolving enzyme (hyaluronidase).
4. Multifunctional and multi-effect injection , it simultaneously achieves filling, wrinkle removal, moisturizing, and shaping, and selects the appropriate molecules for different areas, making it highly personalized.
5. The pain is mild and the procedure is simple. Most products contain lidocaine anesthesia, making the process comfortable and short.
6. It lasts but is not permanent. The effect fades naturally and leaves no foreign matter, making it suitable for those who seek "controllable beauty".

Overall, hyaluronic acid injection is a mature, safe, and effective entry-level cosmetic procedure, especially suitable for people aged 20-50 with mild to moderate aging.
