Injection Depth Mapping
- Superficial dermis (0.5 - 1.0mm) — Fine HA for peri-oral lines and lip definition; minimal product per point.
- Mid dermis (1.0 - 2.0mm) — Derm HA for nasolabial folds and mid-face volume; linear threading technique.
- Deep dermis (2.0 - 3.0mm) — Deep HA for cheek projection and jawline; bolus and fanning techniques.
- Supraperiosteal (3.0mm+) — Subskin HA, PLLA, and CAHA for structural contouring at bone level.
Protocol Timeline
- Pre-treatment — Clients avoid blood thinners and alcohol for 7 days prior. Consent and photographic documentation completed.
- Procedure — 15-45 minutes depending on zones. Topical anesthetic applied; filler delivered with needle or blunt cannula at mapped depth.
- Immediate aftercare — Mild swelling for 24-72 hours. Cold compress and head elevation recommended; no pressure on treated areas for 48 hours.
- Results timeline — HA final result visible at week 2; PLLA and CAHA progressive results over months 3-6 as collagen builds.

Q: Which HA filler viscosity should I use per facial zone?
Fine HA for lips and tear trough, Derm HA for nasolabial folds, Deep HA for cheeks and jawline, Subskin HA for bone-level contouring. Viscosity must match delivery plane for natural results.
Q: What is the difference between cross-linked and non-cross-linked HA?
Cross-linked HA forms a stable gel matrix that resists enzymatic breakdown, providing 6-18+ months of volume. Non-cross-linked HA disperses quickly and is used for hydration, joint delivery, and as a carrier.
Q: Are your fillers reversible?
Yes — Auro Secret HA fillers can be dissolved with hyaluronidase if required. PLLA and CAHA are bio-stimulatory fillers that are not reversible, which is why client selection and depth planning matter.
Q: What syringe volumes are available for wholesale?
1mL, 2mL, 3mL, and 10mL pre-filled syringes. 1mL is standard for facial zones; 2-3mL reduces per-unit cost; 10mL suits body contouring and multi-zone applications.
Frequently Asked Questions
Q: How long do dermal filler results last?
HA fillers typically last 6-12 months depending on viscosity and zone (Fine 6-9, Derm 9-12, Deep 12-18, Subskin 18+). PLLA lasts 18-24 months via progressive collagen regeneration. CAHA lasts 12-18 months. Touch-up scheduling depends on the filler type and the client’s metabolism.
Q: What is the difference between HA, PLLA, and CAHA fillers?
HA (hyaluronic acid) fillers add immediate volume and are reversible. PLLA (poly-L-lactic acid) stimulates the body’s own collagen over months for gradual, long-lasting correction. CAHA (calcium hydroxylapatite) provides structural support with a thicker gel. Most clinics offer all three to match the treatment to the client’s goals and anatomy.
Q: Can fillers be delivered with a blunt cannula?
Yes. Blunt cannulas (22G-30G) reduce bruising and risk in vascular-rich zones like the tear trough, lips, and nasolabial folds. Auro Secret fillers are cannula-compatible across all viscosity grades. Browse blunt cannulas.
Q: What certifications do Auro Secret fillers carry?
All Auro Secret HA fillers carry CE Mark certification and are manufactured in our ISO 13485-certified GMP facility. HA raw material is non-animal origin with BDDE cross-linking below regulatory thresholds. Sterilization reports, biocompatibility data, and batch traceability are provided for market registration.
Q: Do you offer OEM and private-label dermal fillers?
Yes. AuroThread provides full OEM manufacturing for HA fillers across all viscosity grades and syringe volumes. Custom options include branded packaging, logo printing, custom HA concentration or cross-linking density, and multi-language labeling. Flexible MOQ applies — explore our customized service.
