Modern aesthetic practice spans a widening set of modalities — botulinum toxin and dermal fillers, regenerative injectables such as polynucleotides, topical exosomes, biostimulators and skin boosters, and device-based treatments like microneedling. This hub brings together practical, clinically grounded how-to across the techniques we supply, so you can treat confidently and plan combinations well.

What does this hub cover?

Use this as a map of modern practice — each area links to a deeper guide or the products behind it:

  • Injectables — botulinum toxin and hyaluronic-acid dermal fillers.
  • Regenerative injectablespolynucleotides and biostimulators.
  • Topical exosomespost-procedure regeneration.
  • Skin boosters — hydration and skin-quality injectables.
  • Microneedling & skin — device-based remodelling and medical skincare.

Injectables: toxin and filler

Botulinum toxin and hyaluronic-acid fillers remain the backbone of aesthetic practice — toxin for dynamic lines and facial balancing, fillers for volume, contour and structural support. Consistent, natural results rest on sound anatomy, careful product selection and conservative, well-planned dosing rather than volume for its own sake. Browse our dermal fillers and botulinum toxin ranges.

Regenerative & biostimulation

This fast-growing area focuses on improving the skin's own quality rather than adding volume. Polynucleotides (purified DNA fragments) and biostimulators such as poly-L-lactic acid drive collagen and tissue quality over time; topical exosomes support recovery after procedures; and skin boosters hydrate and refine. Start with our polynucleotides and exosomes guides.

Microneedling & skin treatments

Controlled micro-injury — microneedling, with or without radiofrequency — stimulates remodelling and briefly opens a window for topical actives such as exosomes. Combined with medical skincare, these treatments underpin “skin-first” planning and prejuvenation in younger patients.

Combining treatments & planning

The best outcomes usually come from thoughtful combinations sequenced over time — structure with filler, movement with toxin, and quality with regeneratives and devices. Plan around each patient's priorities, downtime and budget, and stage treatments rather than doing everything at once. See building a regenerative treatment plan for a worked example.

Technique, training & safety

Every technique is only as safe as the hands delivering it. Proper training, sound anatomical knowledge, informed consent and a clear complication pathway are non-negotiable — especially for vascular and regenerative work. Our guides are written by clinicians who teach; always treat within your competence and scope, and keep emergency protocols to hand.

Educational content for registered healthcare professionals. Treat within your training and scope of practice, follow each product's IFU/SPC, and maintain an up-to-date complication and consent process.

Frequently asked questions

What treatments does this hub cover?

The core modalities of modern aesthetic practice: botulinum toxin and dermal fillers, regenerative injectables (polynucleotides and biostimulators), topical exosomes, skin boosters, and microneedling with medical skincare.

Do I need separate training for each technique?

Yes. Each modality has its own anatomy, technique and complication profile. Train specifically and only treat within your competence and scope of practice.

How do I combine treatments safely?

Plan around the patient's priorities, downtime and budget, and sequence treatments over time rather than doing everything in one visit — for example structure with filler, movement with toxin, and skin quality with regeneratives and devices.

What's the difference between fillers and regeneratives?

Fillers add volume and structure; regeneratives (polynucleotides, biostimulators, exosomes) work on the quality and resilience of the skin itself rather than adding volume.

Where should a newer injector start?

Build strong foundations in toxin and filler with proper training, then add regenerative and device-based treatments as your confidence and patient base grow.

This guide is intended for registered healthcare professionals. It is educational and not a substitute for hands-on training, the product SPC/IFU, or your own clinical judgement.
