How To Choose The Right Dermal Filler

Dynamic 3D modeling (91% accuracy), verification of medical institution licenses (three certificates), calculate cost-effectiveness via “single price ÷ duration × safety factor,” reserve 7-day recovery period for zygomatic arch filling, prioritize hyaluronic acid with 6-8% cross-linking.

Clarify Improvement Goals

Real example: Last week, a girl brought a influencer’s photo for apple cheek enhancement, but CT scans showed her zygomatic structure couldn’t support heavy filling. Step one isn’t following trends—pinch your own face in the mirror.

For nasolabial folds: Use high viscoelastic materials (e.g., Juvederm Voluma). For lips: Soft low-MW fillers (Restylane Kiss). Pro tip: Under-eye troughs—underfill rather than overfill. 1ml here looks like 2ml.

Recent case: A livestreamer wanted a sharp chin, but palpation revealed masseter compensation. Solution: Dual-phase cross-linked HA + botox. Bone structure > trendy aesthetics. Think “load-bearing walls” first.

Allergen Screening

ER case: Girl injected with “imported fat-dissolving solution” developed rashes—lidocaine allergy (7 cases this year). Anesthetics in fillers riskier than main ingredients, especially for dental anesthesia recipients.

Key ingredients to watch:

• Hydroxypropyl methylcellulose (HPMC): 3% delayed allergy

• Polycaprolactone (PCL): immune reactions during metabolism

• Animal collagen: Use recombinant human collagen

Practical tip: Ear patch test 2 weeks prior. Batch variations matter—a Korean brand’s June batch caused 12x allergy spikes due to sterilant change.

Counterintuitive: “All-natural” products = higher risk. Safe materials list chemical names (e.g., sodium hyaluronate). Demand molecular formulas from salespeople.

Cost-Effectiveness Formula

Beware “299 full-face filler” scams. Example: Cheap HA requires bi-monthly top-ups, costing 4300/year extra. Formula: (Single price ÷ Duration) × Safety factor.

Comparison:

Oily skin metabolizes 30% faster. Demand thermal test reports—6-8% cross-linking optimal. Ask: “Are you charging for HA or cross-linking tech?” Products <2000/ml = red flag.

License Verification Checklist

Shut-down “clinic” employed ex-aestheticians as “doctors.” Mandatory certificates:

1. Medical Practice License

2. Medical Device License

3. Physician Qualification

Steps:

1. Scan QR code linking to NHCC website

2. Verify doctor’s “cosmetic surgery” scope

3. Check product anti-counterfeit codes via NMPA app

Pro tips:

• Check medical waste bins (yellow sharps containers only)

• Demand freezer temp logs (2-8°C for HA)

• Tear open packaging—authentic boxes have peelable seals

• Request “Foreign Physician Temporary License” for “Korea-trained” doctors

• Check autoclave bio-test reports

Effect Simulation Testing

Reject hand-drawn sketches. Use dynamic 3D modeling with three expressions:

1. Smile

2. Surprise

3. 45° side gaze

Tools comparison:

Mark biomechanical points with soluble ink. Demand stress distribution maps—one clinic used architectural software, boosting satisfaction by 89%.

Recovery Periods

“Lunchtime procedures” are myths. Case: Bride’s lip filler swelled into sausages pre-wedding. Formula: Injection time ×3 + (metabolism rate ÷ healing capacity). Oily skin heals 1.5 days faster.

Data:

Zygomatic areas swell 2d longer. Pre-op bromelain cuts swelling by 30%. Critical timelines:

• Family meetings: 7d

• Live-streaming: 10d (cameras amplify swelling 15%)

• Diving/skiing: Ban 28d post-op

Extreme case: Flight attendant’s nasal base filler done in 3 micro-sessions (72h apart) for next-day flights. Precision layering > single injection.
