Which Microneedling Cartridge?
🔹 Nano Cartridge (Round or Square Head) 💉 Non-invasive, “no-needle” microneedling ✅ Best For: 🔬 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: 🔬 Penetration Depth: 0.25 mm
