How To Prepare For Dermal Filler Treatments

Selecting fillers requires dynamic 3D modeling (91% accuracy), verification of medical practice licenses and other three certificates from institutions, calculating cost-effectiveness using “single price ÷ duration × safety coefficient”, reserving 7-day recovery period for zygomatic arch filling, and prioritizing hyaluronic acid with 6-8% cross-linking degree.

Clarify Improvement Goals

Real example: Last week a girl brought influencer photos from social media to request the same apple cheeks, but CT scan showed her zygomatic structure couldn’t support extensive filling. The first step isn’t following trends but pinching your own flesh while looking in the mirror.

For nasolabial folds choose high viscoelastic materials (e.g. Juvederm Voluma) that support deep structures. For lip filling use soft small molecules (Restylane Kiss). Cold knowledge: Under-eye troughs should be underfilled rather than overfilled – 1ml here creates 2ml visual effect.

Recent case: A live-streamer demanded sharp chin filler, but palpation revealed severe masseter compensation. We used biphasic cross-linked HA for gradual filling combined with botox for muscle adjustment. Remember your bone structure matters more than trendy aesthetics, like checking load-bearing walls before renovating.

Check Allergy Risk Components

Last month’s ER case: A girl developed rashes after “imported fat-dissolving injections” at a studio. Found lidocaine allergy – 7 similar cases this year. Anesthetics in fillers pose higher risks than main components, especially for those with dental anesthesia history.

Key components to watch:

Hydroxypropyl methylcellulose (HPMC): 3% delayed allergy rate
Polycaprolactone (PCL): May trigger immune reactions during metabolism
Animal-derived collagen: Absolute red zone – use recombinant human-type

Practical tip: Conduct patch test behind ear 2 weeks prior. Last year a woman discovered cross-linker allergy during testing. Hidden risk: Batch variations – a Korean brand’s June batch caused 12x allergy rate due to sterilizer change.

Counterintuitive warning: “All-natural” products are riskier – plant extracts cause most allergies. Safe materials show chemical names like Sodium Hyaluronate (HA) with verifiable NMPA approval numbers. Demand molecular formula screenshots from salespeople.

Cost-effectiveness Calculation Formula

Never trust “299 yuan full-face filler” ads. A girl choosing cheap HA needed bi-monthly top-ups, spending 4300 yuan extra annually. Real formula: (Single price ÷ Duration) × Safety coefficient.

Comparison table:

Product	Unit Price	Duration(months)	Metabolic Risk	Cost-performance Index
Juvederm Voluma	9800	12	★☆☆☆☆	816
Domestic Brand	2800	4	★★★☆☆	1750
Oily skin metabolizes 30% faster than dry skin. Demand thermodynamic test reports – 6-8% cross-linking gives best value.

When told “high concentration”, ask: “Are you charging for HA quality or cross-linking technology?” A clinic using cheap cross-linkers caused facial swelling last year, paying 170,000 yuan compensation. Warning: Products <2000 yuan/ml are suspicious.

Institution Certification Checklist

Shut-down studio’s “doctor” was actually a beautician. Check three certificates: Medical Practice License, Medical Device License, Physician Qualification Certificate. Missing any? Leave immediately.

Verification steps:

Scan QR code linking to NHCE website
Check doctor’s license number focusing on “cosmetic surgery” scope
Verify product anti-counterfeit codes via NMPA app

Pro tip: Check medical waste bins – legitimate clinics use yellow sharps containers. Demand freezer temperature logs – HA requires 2-8℃ storage. A clinic kept using 17 expired products due to broken fridge last year.

For “Korean-trained” doctors, request Foreign Physician Temporary Practice License. Reliable clinics display emergency flowcharts in treatment rooms. Final check: Demand same-day autoclave biological monitoring report.

Effect Simulation Testing

Reject hand-drawn sketches. A Internet Celebrities got apple cheeks looking like walnuts when smiling. Use dynamic 3D modeling requiring three expressions: pursed smile, surprised look, 45° side gaze.

Simulation comparison:

Method	Time	Accuracy	Cost	Rating
Hand drawing	5min	48%	0	★☆☆☆☆
Static 3D scan	20min	72%	300	★★★☆☆
Muscle motion capture	45min	91%	800	★★★★★

Check nasolabial fold dynamics – no Fault when laughing. Advanced method: Use soluble ink to mark biomechanical points, like CNC machining coordinates.

Doctors saying “this looks good” are suspicious. Professionals show stress distribution diagrams. A clinic using architectural mechanics software achieved 89% satisfaction. Remember: Dynamic tests matter 3x more than static models.

Recovery Period Guidelines

“Lunchtime beauty” claims are scams. A bride got sausage lips 3 days pre-wedding. Recovery formula: Injection duration ×3 + Material metabolic rate ÷ Individual healing capacity. Oily skin heals 1.5 days faster.

Comparison data:

Product	Average Swelling	Full Recovery	Adjustment Interval
Cross-linked HA	3-5 days	14 days	6 weeks
Collagen	1-3 days	7 days	2 weeks
PCL	7-10 days	30 days	3 months

Zygomatic areas swell 2 days longer due to tight fascia. Pro tip: Take bromelain 3 days pre-op reduces swelling 30%.

Critical schedule planning:

Meet parents/ID photos: 7-day buffer
Live-streaming: 10-day minimum (cameras amplify 15% swelling)
Diving/skiing: Avoid 28 days post-op (pressure changes cause displacement)

A host had shiny forehead from lighting 5 days post-filler, mocked for weeks. 4PM injections reduce swelling 8hrs vs morning due to evening lymphatic peak.

Extreme case: Flight attendant’s nasal base filler done in three micro-dose sessions 72hrs apart, ensuring next-day flights. Like CNC layered processing for precision.
