The UK dermal filler market continues to grow, driven by increasing demand for non-surgical facial rejuvenation. For aesthetic practitioners, selecting the right filler products is critical — the choice of product directly impacts clinical outcomes, patient safety, and practice reputation.

Understanding HA Filler Technology

Modern hyaluronic acid-based dermal fillers are classified by their rheological properties — the science of how materials flow and deform:

Key Properties

G' (Elastic Modulus) — Measures the filler's stiffness or ability to resist deformation. Higher G' = more projection and structural support. Ideal for chin, cheeks, and nose

G'' (Viscous Modulus) — Measures flow characteristics. Higher G'' = better spreadability. Suited for lips and superficial lines

Cohesivity — How well the gel holds together after injection. Higher cohesivity = less migration, more predictable results

Cross-linking density — Determines longevity. More cross-linking = longer duration but potentially firmer feel

HA concentration — Typically 15-25 mg/mL. Higher concentration provides more lifting capacity

Choosing Fillers by Treatment Area

Treatment Area | Ideal Properties | Duration
Cheeks / Midface | High G', high cohesivity, firm | 12-18 months
Chin / Jawline | Very high G', volumising | 12-18 months
Lips | Low-medium G', smooth, flexible | 6-9 months
Nasolabial folds | Medium G', good cohesivity | 9-12 months
Tear troughs | Low G', non-hydrophilic, smooth | 12-18 months
Fine lines | Very low G', spreadable | 6-9 months
Non-surgical rhinoplasty | High G', firm, minimal swelling | 12-18 months

The Modelha Range

The Skymedic Modelha range offers a comprehensive portfolio of HA fillers manufactured under ISO 13485 conditions in Barcelona. Each product is formulated with specific rheological properties matched to clinical indication:

Modelha Densify — High-density, cohesive filler for deep volume restoration (cheeks, chin, jawline). High G' with excellent projection

Modelha Lips — Smooth, flexible formulation specifically engineered for lip augmentation. Low G' for natural movement and feel

Modelha Fine — Ultra-smooth, low-viscosity filler for superficial lines and delicate areas

All Modelha products contain lidocaine for patient comfort during injection.

Safety Considerations

Patient safety in filler treatment depends on three pillars:

Product Quality

Source only from authorised suppliers with verified supply chains

Verify ISO 13485 certification and CE/UKCA marking

Check batch numbers and expiry dates before every treatment

Avoid counterfeit products — purchase directly from manufacturer or authorised distributor

Anatomical Knowledge

Comprehensive understanding of facial vascular anatomy is essential

Know the danger zones: glabella, nasal tip, nasolabial fold arteries

Aspiration technique and slow injection reduce vascular compromise risk

Use cannulae where appropriate to reduce vessel damage risk

Emergency Preparedness

Hyaluronidase must be available in every clinic performing HA filler treatments

Written emergency protocols for vascular occlusion

Staff trained in recognising and managing complications

HA fillers are reversible — this is a significant safety advantage over non-HA fillers

UK Regulatory Framework

The regulatory landscape for dermal fillers in the UK is evolving:

HA fillers are not currently classified as medical devices for cosmetic use in the UK (unlike the EU)

The Health and Care Act 2022 introduced licensing requirements for non-surgical cosmetic procedures in England

Practitioners must be on a register of licensed practitioners (implementation ongoing)

Professional indemnity insurance is essential and typically requires evidence of training

CQC registration may be required depending on the procedures offered alongside fillers

Building a Filler Portfolio

For new practitioners or clinics expanding their offering, a practical starter portfolio includes:

1. A volumising filler — For cheeks, chin, and deep tissue augmentation

2. A lip-specific filler — Lip augmentation is typically the highest-demand treatment

3. A fine/superficial filler — For perioral lines, tear troughs, and skin boosting

4. Hyaluronidase — Emergency reversal agent (mandatory stock item)

The complete Modelha range covers all these indications. Professional accounts include wholesale pricing and clinical support.

Frequently Asked Questions

How do I choose between filler brands?

Evaluate based on: manufacturing standards (ISO 13485), rheological data for your intended use, clinical evidence, trainer support, pricing consistency, and product range breadth. Sticking with one manufacturer for core products ensures familiarity with product behaviour.

What training do I need to inject fillers in the UK?

No single mandatory qualification exists, but reputable practice requires: a healthcare background (doctor, dentist, nurse prescriber), specific dermal filler training from an accredited provider, competency in facial anatomy, and emergency management training. Many insurers specify minimum training hours.

How should fillers be stored?

Most HA fillers should be stored at 2-25°C, protected from light and freezing. Always check manufacturer specifications. Ensure your supply chain maintains cold-chain integrity during delivery.
