🔬 Key Takeaways
- For Lips (Plump & Smooth): Juvéderm Volbella / Ultra XC or Stylage M (smooth blending, lower swelling)
- For Cheeks & Jawline (Structure & Lift): Restylane Lyft or Juvéderm Voluma (high G-prime for deep projection)
- For Under-Eye Tear Troughs: Restylane Kysse / Eyelight or Teosyal Redensity II (minimal water attraction)
- All are Hyaluronic Acid (HA): Reversible with Hyaluronidase if needed.
1. The Science Behind Hyaluronic Acid Fillers
Not all hyaluronic acid (HA) gels behave the same way under the skin. Aesthetic medicine categorizes fillers based on three essential biomechanical properties:
G-Prime (Elasticity)
The ability of the gel to resist deformation and provide vertical lift against gravity and muscle pressure.
Cohesivity
How well the gel particles hold together under shear force, preventing product spreading or migration.
Hydrophilicity
How much water the molecule absorbs post-injection, determining initial swelling versus true volume.
2. Head-to-Head Comparison Matrix
| Brand & Line | Cross-Linking Tech | Texture / Feel | Best Treatment Areas | Expected Duration |
|---|---|---|---|---|
| Juvéderm (Allergan) | Vycross & Hylacross | Smooth, cohesive, soft | Lips, nasolabial folds, volume restoration | 9 – 24 months |
| Restylane (Galderma) | NASHA & XpresHAn | Granular, firm, flexible | Cheek projection, chin, under-eye troughs | 12 – 18 months |
| Stylage (Vivacy) | IPN-Like + Mannitol | Antioxidant-infused, elastic | Lips, fine lines, temples, hands | 9 – 14 months |
| Teosyal (Teoxane) | RHA (Resilient HA) | Dynamic stretch, natural motion | Perioral lines, dynamic facial expressions | 12 – 18 months |
3. Pricing & Syringe Economics
Dermal fillers are priced per syringe (usually 1.0 ml). In top-tier aesthetic clinics, pricing generally ranges from $450 – $950 / £300 – £650 / 3 200 – 6 500 SEK per ml, depending on the product line, injector expertise, and geographical market.
