🔹 Nano Cartridge (Round or Square Head)
💉 Non-invasive, “no-needle” microneedling
✅ Best For:
- Transdermal product delivery (serums, exosomes, vitamin cocktails)
- Enhancing glow and texture
- Enlarged pores
- Under-eye area
- First-time or sensitive skin clients
- Daily/weekly use (no downtime)
🔬 Penetration Depth: 0.15–0.25 mm (surface of stratum corneum)
⚠️ Nano heads do not pierce the skin deeply — they’re more like micro-exfoliators that improve absorption without causing inflammation.
🔹 12-Pin Cartridge
💉 Deeper, more focused collagen induction
✅ Best For:
- Acne scars and pitted scars
- Stretch marks
- Deep wrinkles & skin laxity
- Targeted areas (e.g., nasolabial folds, crow’s feet, acne marks)
🔬 Penetration Depth: 0.25 mm – 2.5 mm
(Adjust depth based on area and concern)
💡 Fewer needles = more pressure per needle → stronger stimulation, ideal for intensive collagen remodelling.
🔹 16/18-Pin Cartridge
💉 Balanced and versatile treatment head
✅ Best For:
- Full-face rejuvenation
- Mild to moderate wrinkles
- Light pigmentation or skin dullness
- Preventative anti-aging
- Maintenance treatments
🔬 Penetration Depth: 0.25 – 1.5 mm
🧬 16 or 18-pin offers a good balance of coverage and precision, with more needles for a faster treatment time, and is slightly gentler than the 12-pin.
