Youthfill Filler 1.1ml — RFBio HoPE Technology HA Filler Series
What it is
Youthfill is a 3-variant Korean HA filler series manufactured by RFBio Co., Ltd. — engineered with proprietary HoPE technology to deliver 24 mg/cc cross-linked HA across all three viscoelasticity tiers. The differentiated cross-linking degree per variant determines dermal depth and indication, while shared HoPE technology delivers high storage modulus (G′), low degradation rate, and extended duration. HA raw material is EDQM-certified (European Pharmacopoeia) with endotoxin controlled below 0.04 IU/mg. 0.3% premixed lidocaine reduces injection discomfort.
Variant comparison
All variants share core technology and HA raw material — differentiated by viscoelasticity tier and indication.
| Variant | Specification & indication | Price |
|---|---|---|
| Youthfill Fine | 24 mg/cc HA + 0.3% lidocaine · 1 × 1.1 mL · Fine lines, periorbital, perioral, Russian lip technique | $35.00 |
| Youthfill Deep | 24 mg/cc HA + 0.3% lidocaine · 1 × 1.1 mL · NLF, marionettes, lip modeling, chin shaping | $42.00 |
| Youthfill Shape | 24 mg/cc HA + 0.3% lidocaine · 1 × 1.1 mL · Cheek, chin, jawline, nose contouring (sub-Q) | $52.00 |
How HoPE Technology works
RFBio’s proprietary HoPE technology produces cross-linked HA gel with high storage modulus (G′) for structural support and low degradation rate for extended in-tissue longevity. The three Youthfill variants share identical HA raw material (24 mg/cc, EDQM-certified, endotoxin < 0.04 IU/mg) and are differentiated by cross-linking degree — yielding distinct viscoelasticity tiers matched to variant-specific dermal depth and clinical indication. The 24 mg/cc concentration is higher than the typical 20 mg/mL Korean filler standard, supporting denser volume correction.

FAQ
How do Fine / Deep / Shape variants differ?+
All three Youthfill variants share 24 mg/cc HA + 0.3% lidocaine with HoPE technology — they differ in cross-linking degree and resulting viscoelasticity. Fine — softest, low-density, superficial wrinkles around eyes/lips/neck, fine lines, Russian lip technique. Deep — medium firmness, mid-deep dermis, NLF, marionettes, lip modeling, chin shaping. Shape (Sub-Q) — most viscous, subcutaneous, cheek/chin/jawline/nose contouring, neck reconstruction, deep wrinkles.
Why 24 mg/cc instead of 20 mg/mL?+
Most Korean HA fillers use 20 mg/mL concentration. Youthfill’s 24 mg/cc (approximately 24 mg/mL) is higher — supporting denser volume correction with the same injection volume, which can extend longevity in static volumising zones and provide stronger structural support per ml. Combined with HoPE technology’s high G′, this supports the line’s extended duration claim.
How long does Youthfill last?+
Duration ranges 6–12 months depending on variant and injection site. Fine — typically 6–9 months in mobile fine-line zones. Deep — 9–12 months in mid-deep dermal indications. Shape — up to 12+ months in static contouring zones (cheek, jawline) due to highest cross-linking and low degradation rate. Patient metabolism and lifestyle affect actual longevity.
What’s the storage requirement?+
Standard HA filler storage at 2–25 °C (room temperature acceptable). Do not freeze. Protect from direct sunlight. 24-month shelf life unopened; verify lot label before use.
Where to buy wholesale and verify authenticity?+
Wholesale through MJS Medicals for licensed healthcare professionals. Verify authenticity: (1) intact tamper-evident sterile seal on syringe; (2) batch number matching between outer box and syringe; (3) RFBio manufacturer information visible; (4) Youthfill and variant name (Fine/Deep/Shape) clearly printed; (5) CE marking present; (6) HA concentration 24 mg/cc on packaging.

Shape (Sub-Q): deep subcutaneous in cheek, chin, nose dorsum, jawline — proximity to facial / dorsal nasal arteries; aspirate before injection; cannula strongly recommended for nose enhancement and vascular zones. Deep: mid-deep dermal in NLF, marionettes, lip — facial artery branch proximity. Fine: superficial dermis in periorbital, perioral — risk of Tyndall effect if too superficial; angular artery proximity. Pregnancy / breastfeeding: insufficient safety data, contraindicated.
Prescription medical device. Contraindicated in known hypersensitivity to HA, lidocaine, or Gram-positive bacterial proteins; severe allergies / anaphylaxis history; pregnancy / breastfeeding; autoimmune disorders; active local infection; concurrent anticoagulant therapy.
