VOKAL JOURNAL / The pigment reference
A pale pigment can make a colour look softer. That does not make it simpler to remove.
Titanium dioxide, listed as CI 77891, is a white colorant used to add brightness and opacity. In permanent makeup, it can be part of a coloured formula rather than a bottle labelled “white”. White and flesh-toned cosmetic tattoos can sometimes become darker during laser treatment. That possibility deserves a conversation before treatment, not an explanation afterwards.
This guide separates three questions: what titanium dioxide does optically, what published reports say about darkening, and what information a practitioner should recover before discussing removal. It is an ingredient reference, not a treatment protocol.
What titanium dioxide actually does
A transparent brown lets more of its background remain visible. An opaque beige can hide more of it. Colour and coverage are different properties, even when two swatches look similar at first glance.
Titanium dioxide is an effective white pigment because it scatters visible light. Its optical behaviour depends on factors including particle size, crystal structure, surface treatment and the surrounding medium. Rutile and anatase are two crystal forms. The manufacturer’s explanation of titanium dioxide in coatings is a useful introduction to that material science; it is not evidence that a particular PMU formula will behave like paint or is suitable for implantation.
In a finished pigment, titanium dioxide sits alongside other ingredients. Absorption and scattering can both contribute to what we see. It is too simple to divide every bottle into “absorbs everything” and “scatters everything”, or to infer the amount of titanium dioxide from a product photograph.
| Property | What it describes | What it does not establish |
|---|---|---|
| Hue | The colour direction: brown, red, yellow or another colour. | The full ingredient list. |
| Opacity | How much a layer hides what is behind it. | A specific concentration of CI 77891. |
| CI identity | The named colorant on the label. | The response of an entire tattoo to a laser. |
Why absorption matters to a removal laser
Laser tattoo removal depends on the interaction between a particular pulse and the material it reaches. Wavelength, pulse characteristics, pigment composition and skin all matter. A visible colour name is not enough to choose a device or a setting.
The diagram distinguishes two optical processes. It does not say that every scattered ray is absorbed by surrounding skin, that titanium dioxide absorbs no energy under any conditions, or that a dark pigment responds to every wavelength. Those shortcuts turn an explanation of light into an unreliable treatment rule.
For a client, the useful question is whether the clinician has assessed this particular cosmetic tattoo, including any pale modifiers or cover-up layers. A machine’s wavelength list is only one part of that assessment. More power is not a substitute for identifying the target and considering the skin around it.
Can white or flesh-toned PMU turn dark?
Yes. Paradoxical darkening is a recognised complication of laser treatment of some cosmetic tattoos. The FDA’s consumer guidance specifically warns about white, flesh-coloured and permanent-makeup pigments becoming dark and difficult to treat. That warning is a reason to take the risk seriously.
It is not accurate, however, to promise that every darkened tattoo is either permanently untreatable or reliably removable with further laser sessions. In a published five-case report by Anderson and colleagues, further laser treatment cleared three cases; two did not clear with further laser treatment and required surgical excision. These were reported cosmetic-tattoo cases, not VOKAL cases or a success-rate study for modern products.
The same paper describes experimental darkening of an iron-oxide material and discusses chemical change as a possible explanation. It does not establish one universal mechanism for every titanium-dioxide-containing mixture. An image of a darker brow cannot reveal which ingredient changed, whether another colour became more visible, or how much pigment was originally implanted.
A useful consent sentence: “This pigment may darken or remain visible. We cannot guarantee complete clearance, and the plan may need to change after assessment and review.”
Published cases demonstrate possibilities, not a personalised probability. A clinician should explain the evidence and uncertainty relevant to the actual pigment history. Avoid both an invented percentage and an unqualified promise that a test spot eliminates the risk.
Where to look for CI 77891
Start with the ingredient list, not the shade name. White or titanium dioxide may be included in pale shades, flesh tones, modifiers and some other coloured mixtures. The exact formula matters more than a product category.
| Product or history | Question worth asking |
|---|---|
| Beige or skin-toned modifier | Does the actual label list CI 77891, and what is the intended use? |
| Lip pigment or neutraliser | Which colorants and modifiers were used? Do not assume all neutralisers contain white. |
| Areola or scar-camouflage work | Can the original products and treatment history be recovered? A category name does not give a formula. |
| A main brown shade | Check the complete colorant list, even if the bottle does not look pale. |
| Something called a “lightener” | Is this an implanted colour modifier or an entirely different product? A marketing name does not explain its action. |
A listed ingredient establishes what the manufacturer declares, not an independent laboratory analysis or an exact percentage. If the information is incomplete, ask the manufacturer for the batch-relevant documentation. Record uncertainty rather than filling it with a guess.
A colour correction adds a new decision
Putting a new pigment over old work changes its appearance by adding material. That is different from removing the existing pigment. A cover-up can therefore affect future options, even if the immediate colour looks more acceptable.
The discussion should include the client’s goal, the existing work, the proposed product and the possibility that a later removal specialist will encounter several layers. Do not describe a beige modifier as erasing old pigment or promise that a surface swatch predicts a healed result.
A modifier has a role.
Identify the intended use. Read the current ingredient label. Discuss what adding another colour means for the longer-term plan.
For example, the current V06 Corrective Beige product description identifies a skin-toned beige for small, localised brow-detail corrections. That is its stated role. The photograph above identifies the product; it is not a clinical result or a substitute for checking the current bottle’s full colorant list.
A product being available does not make it appropriate for every old brow. The decision to add pigment, seek a removal consultation, wait or leave the area untreated should follow an individual assessment. The important distinction is between changing the visible colour and reducing the existing pigment.
If someone asks you to remove it
White, flesh-toned or previously covered work deserves assessment by a qualified clinician experienced in cosmetic-tattoo removal. Recovering the history is more useful than beginning with a promised session count.
- Bring the evidence. Original labels, shade names, batch numbers, prior treatment notes and photographs can help establish what may be present.
- Discuss a test site where appropriate. Published reports recommend considering test areas. The clinician determines how to evaluate the response and when to review it; a reassuring small-area response cannot guarantee every larger-area outcome.
- Include the possible trade-offs. Darkening, incomplete clearance, scarring and changes in skin pigmentation should be part of informed discussion.
- Agree on review and stopping points. An unexpected response calls for reassessment, not an automatic increase in treatment intensity.
This article deliberately gives no wavelength or energy recipe. A label alone cannot establish safe settings, and a product page cannot replace clinical assessment. If a practitioner cannot explain the uncertainty and alternatives, the client has not yet received a complete account of the decision.
Before you buy a pigment
Read the complete packaging before deciding that a pale or opaque formula suits the job. Keep the following questions together:
- Does the colorant list include CI 77891?
- What is the product’s stated role: main shade, modifier or something else?
- What information does the manufacturer provide about composition, handling and compatibility?
- Which questions remain unanswered by the label?
Opacity is a design property, not automatically a defect. The aim is to choose deliberately and document the choice. An ingredient list may not reveal the exact amount of opacifier, so do not translate its presence into a made-up concentration or a guaranteed removal outcome.
Follow the actual product’s instructions for storage, mixing and dilution. For the VOKAL V06 product referenced here, the current instructions say not to dilute with water or other solutions. Generic advice to “add a thinner” should never override a product-specific restriction.
Leave a record that another person can use
A useful record connects the physical bottle to the treatment. Photograph the readable label, record every modifier and amount used, and retain the date and treated area. Include previous treatments if known. Do not write a precise implantation depth retrospectively when it was not measured.
Consistent photographs make later comparison easier: similar lighting, angle and distance, with dates attached. They do not diagnose the pigment’s chemistry. Records support a better assessment; they cannot turn an uncertain outcome into a guaranteed one.
