INORGANIC VS ORGANIC - PARTICLE SIZE
Let’s talk about why you’re wrong when you say that inorganic pigments are harder to implant because their particle sizes are larger, while hybrid organics implant more easily because the particles are smaller.
To whoever started that rumour, I’d kindly suggest dunking them into a bucket of Roasted Chestnuts.
For this experiment, we’ll need a grindometer and your full focus.
WHAT'S A GRINDOMETER?
It’s a chunk of stainless steel, precision-machined and marked with a scale in microns and nanometers. We’re particularly interested in the 500 nm to 1.5–2 µm range, which is the optimal particle size for tattoo and PMU pigments.
I picked up this tool from the paint and coatings industry. They use it to measure pigment particle sizes in things like wall paints.
It’s a simple but highly accurate way to analyse the particle size distribution in any pigment formula.
How to determine the particle size?
Spread the pigment across the grindometer and observe where it begins to “stripe”—that’s where particles start catching on the etched surface. These marks show us the range of particle sizes.
Now, let’s compare BROVI’s hybrid organic and BROVI ONE’s inorganic pigments, and I’ll show you that they consist of particles of the same size.
1) BROVI Hybrid Organic (Roasted Chestnuts): 500 nm to 1.5 µm
2) BROVI ONE Inorganic (Neutral Dark Brown): 500 nm to 1.5 µm
Now, you must be having even more questions.
WHY DOES INORGANIC INK STILL FEEL HARDER TO IMPLANT?
There are two answers:
#1
Basically, iron oxide pigments (used in most inorganics) are naturally muted and are simply not as visible on the skin as the organic ones.
They also don’t heal as vividly. Plus, our body begins breaking them down almost immediately since iron oxides are biocompatible materials.
Add to that the fact that most inorganics don’t contain titanium dioxide (which adds opacity), and it’s no surprise they can appear like they didn’t take well and took a long time to implant.
#2
Some manufacturers' products may indeed contain larger particles than in BROVI pigments. Different manufacturers = different technologies and goals. And to be fair, larger particles (within reason) aren’t necessarily bad—but they are indeed harder to implant with a single needle.
You’d need to work with larger groupings, which is more typical for traditional colour tattoos, not PMU.
But that’s no reason to generalise the whole industry based on one brand’s formula, is it?
You’ve worked with enough products to know better and now, you know one more secret.
