The Truth About PMU Pigments: Organic, Inorganic, Hybrid – and the Myth of “Micronised” Ink

🎨 The Truth About PMU Pigments: Organic, Inorganic, Hybrid – and the Myth of “Micronised” Ink

If you’ve been in the PMU industry for more than five minutes, you’ve probably witnessed the never-ending debates: “Which pigments are better—organic or inorganic?”, “Are hybrids the answer?”, or “Is it true that some pigments are semi-permanent because they’re micronised to fade faster?”

With every new pigment line comes another round of marketing buzzwords designed to make their product seem revolutionary. The truth? Much of it is smoke and mirrors.

Let’s break down the science, bust the myths, and explain what actually matters when it comes to choosing the right pigments for your clients.

🍃 Organic Pigments: The ‘Waitrose’ of the Ink World?

Once upon a time, “organic” was the holy grail of pigment marketing. It sounded clean, pure, even luxurious – something you might pick up along with your kale at Waitrose. But in chemistry terms, “organic” simply means carbon-based.

Organic pigments are often synthetic dyes bonded to carbon structures. They tend to be brighter and more vibrant, which is why they were popular in PMU when bold brows and vivid lips were trending.

However, they come with some challenges:

• Less stability in the skin
• Tendency to fade quicker
• Increased risk of colour shifts

So while they may look great at first, they don’t always age well. They’re also more easily broken down by the body’s natural immune response.

🪨 Inorganic Pigments: The Reliable Workhorse

Inorganic pigments are mineral-based, typically composed of iron oxides, titanium dioxide, and ultramarines. These pigments are more stable and fade predictably over time.

They’re generally:

• Softer and more natural in tone
• Longer-lasting in the skin
• Less prone to shifting into undesired hues

And here’s the proof: black iron oxide inks used in traditional tattoos remain visibly black decades later. We’ve seen this ourselves – clear, long-lasting definition even in older skin – when tattooed correctly by an experienced artist – the correct technique, at the correct depth.

In short, if you’re after longevity, predictability, and subtlety, inorganics are your best friend.

🔀 Hybrid Pigments: Old Concept, New Marketing

The latest trend? “Hybrid” pigments – marketed as a clever mix of organic and inorganic ingredients. But here’s the thing: hybrids are nothing new. Tattoo artists have been using mixtures of organics and inorganics for decades. Famous brands have long had hybrid compositions.

The theory goes like this:

• Organic pigments tend to fade blue 🟦
• Inorganic pigments fade more orange 🟧
• So if you mix them, the fade-out will “balance itself”

Sounds plausible, right? Unfortunately, it’s not that simple.

Organic pigments are still less stable, meaning they fade faster, leaving the remaining colour dominated by the more persistent inorganic base. This can still lead to unexpected shifts over time.  This is also dependent on the practitioner’s skill level and technique. The truth is, what really matters is how similar the combined pigments are in terms of particle size, behaviour, and stability – not just that they’re mixed.

🧬 The Macrophage Effect: Your Body’s Cleanup Crew

Pigment fading isn’t just about sunlight and skin type. Our immune system plays a huge role – specifically, a type of white blood cell called a macrophage.

When pigment is implanted into the skin, macrophages get to work identifying it as a foreign particle. They engulf and break down pigment over time. Smaller and less stable particles (like many organics) are much easier for them to digest and remove, whereas inorganic particles are denser and more resistant.

This is why pigment longevity is about more than just the colour – it’s about how the body processes what’s implanted.

🌞 Sunlight, Skincare & Aftercare: Still Crucial

Regardless of pigment type, the external environment will influence fading. Factors like:

• UV exposure
• Retinol use
• Skin peels and exfoliants
• Poor aftercare compliance

…all accelerate fading, particularly for lighter and warmer tones. This is where education becomes essential – for artists and clients alike.

💬 The “Micronised” Marketing Gimmick

Now let’s address a newer myth in the pigment marketing playbook: micronised pigments.

Some brands now claim their “semi-permanent” pigments are micronised to fade faster. It sounds scientific, but it’s completely misleading.

Here’s the truth:

• Every pigment has a natural particle size. For iron oxide, for example, it’s already very fine – often less than a few microns.
• You can’t reduce a pigment particle beyond its stable structure without destroying it. If it’s too small, it ceases to reflect light correctly, affecting both colour and safety.
• You can’t engineer fading just by “micronising” a pigment beyond its inherent size. The only way to significantly change how fast a pigment fades is by altering:
  • The pigment load (how much pigment is in the carrier)
  • The quality or purity of the pigment
  • The formula stability
  • Technique (depth of implantation)

So, if a brand claims their “semi-permanent” pigments fade faster simply because of their particle size, but the ingredients are the same as a “permanent” ink, you’re being sold a story—not science.

“Micronized” when we talk about iron oxides or titanium dioxide is actually thing, but only when talking about sun screen ingredients where pigment stability isn’t required.  But when it comes to tattoo ink, or PMU pigment (which are the same thing), this is not relevant and complete nonsense if a manufacturer makes this claim.

📚 Education Over Influence

In a world full of flashy pigment ads, it’s easy to get lost in brand jargon and trendy buzzwords. But PMU professionals need to lean into education, not just aesthetics.

Here’s what matters most when choosing pigments:
✅ Ingredient transparency
✅ Proven fade behaviour
✅ Stable formulation

✅ Similar pigment characteristics in a mix (size / shape)
✅ Match between pigment type and treatment goal

And yes – educating your clients about the truth behind pigment behaviour will build more trust and set better expectations for healed results.

🔎 The Bottom Line

The pigment you choose isn’t just about colour – it’s about chemistry, skin interaction, longevity, and trust. Organic, inorganic, hybrid – they all have their place. But don’t be swayed by surface-level claims like “micronised” or “semi-permanent by design.”

Focus on quality. Focus on what lasts. And never stop asking why something works the way it does.

Because in PMU, what’s under the surface matters just as much as what’s on top.
