Hyaluronic Acid Fillers

What are HA fillers?

Hyaluronic acid (HA) is a naturally occurring sugar that binds water and keeps tissue elastic. As a filler it is formulated into stabilized gels that add volume, define contours, and harmonize light reflections. Key advantages: HA can be dosed precisely, is well tolerated, and—if needed—can be dissolved with hyaluronidase. That’s why it is the preferred facial filler.

Types, consistencies & brands

Not all fillers are the same. Gels differ in:

  • Rheology/cohesivity: from soft (for fine, mobile areas) to more structured/supportive (for chin, jawline, cheeks).
  • Particle size & cross-linking: influence projection, water binding, and longevity.
  • Monophasic vs. biphasic: smoother flow vs. particle-based—each useful depending on the area.

Established brand families include Juvederm®, Restylane®, Belotero®, Teosyal®. Selection is based on anatomy, goal, and safety of the specific area—not the brand name.

Indications – where HA makes sense

HA is suitable for restoring volume and smoothing transitions:

  • Cheeks & zygoma: projection, youthful light line.
  • Nasolabial & marionette region: gentle softening, often after cheek support.
  • Chin & jawline: definition, profile harmonization, chin–neck transition.
  • Temples: deflation correction—planned very deliberately.
  • Tear trough/lower lid: only selectively with suitable anatomy (risk of swelling).
  • Nose (“liquid rhinoplasty”): minor irregularities—anatomically high-risk; strict indications.
  • Lips: shape, border, hydration—details on a separate lip-filler page.

“Filling a little everywhere” is not a concept. Every injection needs a clear goal, correct plane, and risk assessment.

Longevity – why it varies

Average duration 6–12 months; often longer at chin/jawline, shorter in lips and highly mobile zones. It depends on:

  • Product/cross-linking (more robust = usually longer)
  • Injection plane (deeper = more stable)
  • Movement & metabolism
  • Lifestyle (UV, smoking, sleep)

Top-ups are conservative—prefer small steps with fine-tuning over big volume jumps.

Planning & consultation – why they matter

Before treatment we clarify indication, limits, and alternatives (e.g., botulinum toxin, collagen stimulation, in some cases surgery). Future plans are considered: anyone wanting a rhinoplasty later should know nasal HA must be completely dissolved in time before surgery. Some surgeons charge extra or won’t operate while filler remains. Similar considerations can apply in other regions.

Procedure & aftercare

After photo planning and marking, we inject with a fine needle or blunt cannula, low pressure, and aspiration. Then: cool the area; avoid sport/heat for 24–48 h; don’t massage or press treated sites. Minor swelling/bruising is common and subsides. A 2–4 week review allows fine-tuning.

Safety & risks – clear and honest

HA fillers are safe with correct technique, yet still medical procedures. Possible:

  • Short-term: redness, swelling, bruising, pressure, temporary asymmetries.
  • Specific/rare: vascular compression/occlusion (emergency—immediate hyaluronidase), Tyndall effect/shimmer from too-superficial placement, delayed reactions/nodules (incl. biofilm), migration with overfilling, persistent swelling tendency (e.g., tear trough).
  • High-risk areas: nose, glabella, lower lid—experience, correct plane, cannula use, and conservative amounts are crucial; when in doubt, don’t treat.

We do not use permanent facial fillers. Contraindications: pregnancy/breastfeeding, active infections, certain autoimmune/coagulation disorders, or unrealistic expectations.

Bottom line: Hyaluronic acid is a versatile, reversible tool for harmonious facial proportions—when used with the right indication, dose, and anatomy. Because longevity, risk, and technique vary by region, thorough consultation is the most important step.
