Inorganic semi cream PMU pigments use iron oxide colorants in a semi-cream base, offering the safest profile for sensitive skin with minimal healed color shift and long-lasting results.

The term 'inorganic' refers to the pigment's colorant source — iron oxides mined and purified to cosmetic grade, not synthetic organic dyes. These pigments have been used in medical tattooing for decades with an extensive safety record. The semi-cream texture sits between liquid and full cream, providing enough body for controlled brow work while flowing smoothly through cartridge needles. CharmingTattoo's inorganic semi cream line includes 25+ shades, all EU REACH compliant and batch-tested for heavy metals.

Composition & Safety Profile

Iron Oxide Colorants

Source: Naturally occurring minerals purified to cosmetic/pharmaceutical grade (USP/FDA standards).

Safety Record: Decades of use in medical tattoos, permanent makeup, and cosmetics with the lowest reported allergy rate among all PMU pigment types.

Semi-Cream Texture

Viscosity: Medium-thick, similar to a light gel. Holds shape well on the needle tip, preventing drips and providing precise placement control.

Flow: Smooth through 1RL-5RL and 3RS-7RS cartridges with minimal resistance.

Color Stability

Healed Shift: Less than 10% — among the lowest of any PMU pigment type.

Fade Behavior: Iron oxides maintain their original hue as they lighten, never shifting to blue, green, or red like some organic pigments.

REACH & Regulatory

EU REACH 2022: All shades compliant. Iron oxides are on the EU's approved pigment list with no usage restrictions for cosmetic tattooing.

Testing: Each batch undergoes heavy metal screening (Pb, As, Cd, Hg), microbial testing, and stability validation.

Who Should Choose Inorganic Semi Cream

Sensitive & Reactive Skin: Clients with eczema, rosacea, or autoimmune conditions benefit from iron oxide's gentle profile and decades of safety data.

Allergy-Prone Clients: If a client has reacted to organic pigments before, inorganic is the safest alternative with the lowest cross-reactivity risk.

Brow Procedures: The semi-cream texture excels at both hair-stroke microblading and powder/ombre techniques, with enough body for crisp lines.

Long-Term Clients: Those wanting minimal maintenance appreciate the 24-36 month retention and predictable fading.

Medical PMU: Areola restoration, scar camouflage, and cleft lip correction all use iron oxide pigments for their medical-grade safety.
