Nano organic PMU pigments are ultra-fine cosmetic tattoo pigments with particle sizes under 100 nanometers, specifically engineered for facial permanent makeup procedures.
Unlike traditional tattoo inks that deposit deep into the dermis for permanent body art, nano organic PMU pigments are designed to implant precisely at the dermal-epidermal junction. This allows them to heal with soft, natural-looking results and fade predictably over 12–36 months — making them the preferred choice for eyebrow microblading, lip blush, and eyeliner treatments. CharmingTattoo has been formulating professional-grade nano organic PMU pigments since 2002, with every batch tested for EU REACH compliance.
Key Differences: Nano Organic PMU Pigments vs Traditional Tattoo Inks
Particle Size & Implantation
PMU Pigments: Sub-100nm particles implant at the dermal-epidermal junction (0.1–0.3mm deep), allowing smoother application and natural fading.
Tattoo Inks: 1–5 micron particles implant deep in the dermis (1–2mm) for permanent retention.
Color Formulation
PMU Pigments: Balanced organic-inorganic hybrid blends engineered to fade into neutral warm/grey undertones. CharmingTattoo formulates each shade with C.I. (Color Index) transparency.
Tattoo Inks: High-saturation organic colorants optimized for decades of vibrancy, often shifting to blue-green tones over time.
Fading & Longevity
PMU Pigments: Metabolized gradually over 12–36 months, enabling color refresh and trend adaptation. Annual touch-ups recommended.
Tattoo Inks: Designed for decades with minimal fading. Removal typically requires laser treatment.
Safety & Regulation
PMU Pigments: Modern formulations comply with EU 2022 REACH regulation restricting 4,000+ harmful substances. CharmingTattoo pigments undergo batch-level safety testing.
Tattoo Inks: Face less stringent cosmetic regulation in many regions, though EU REACH now also applies to tattoo inks from 2022.
