by Rae Denman.
When I receive instructions for a medico-legal assessment, the questions are usually focused and
practical. What treatment would I recommend? How many sessions are likely to be required? At what intervals? Will future colour boosts be needed? What are the current and future costs?
The claimant then attends with those questions already set out in the letter of instruction. My role is to assess each area of scarring and determine whether medical tattooing is appropriate, what it can reasonably achieve and where it should sit within the wider treatment pathway.
The figures matter, but they only become meaningful once the clinical plan has been established. The colour, texture, maturity and symptoms of the scar may all affect the recommendation. Another treatment may need to come first, different areas may require different approaches, and not every scar will be suitable for medical tattooing.
What a specialist assessment adds
Scar cases often sit across several disciplines. A plastic surgeon may address surgical revision. A
laser specialist may assess vascularity, pigmentation or texture. A scar physiotherapist may assess
adherence, sensitivity or restriction of movement. Psychological support may be relevant where
the visible difference or the circumstances of the injury are causing significant distress. A medical tattooist assesses whether colour re-pigmentation or the reconstruction of lost feature definition is appropriate.
Each discipline addresses a different element of the scar. The sequence is clinically relevant because treatment that substantially remodels the tissue may alter an area that has already been tattooed. Equally, a scar that is still raised, red, symptomatic or changing may require treatment before colour repigmentation is considered. In other cases, medical tattooing may be the appropriate next step without further intervention.
My assessment therefore considers the concern medical tattooing can address, whether the tissue is ready, whether another specialist should be involved first, the likely limitations and the reasonable future provision required.
Photographs are valuable for showing the site, distribution and colour difference, but they may not
reliably demonstrate pliability, adherence, subtle elevation or depression, and sensitivity. Depending on the issues raised by the instructions, in person examination may be needed before a final treatment plan can be given.
A scar is not one problem
In conversation, we often speak about a scar as though it were a single clinical entity. In practice,
the same scar can contain several different concerns:
• colour difference, including hypopigmentation, hyperpigmentation or persistent redness
• texture, including raised, indented, tethered or irregular areas
• symptoms such as itch, pain, sensitivity or altered sensation
• functional restriction or adherence
• loss of a recognisable feature, such as an areola, lip border, eyebrow or hairline
• the psychological and social effect of a visible difference
No one treatment resolves all of these. The primary purpose of medical tattooing is to implant colour, not to flatten a hypertrophic scar, release tethering or treat pain. The repeated needle action can also have a smoothing effect on selected scars. In my own clinical practice, I sometimes see tissue soften and shallow atrophic areas lift during a course of treatment. This is a clinical observation rather than a predictable primary outcome, and I would not recommend medical tattooing on that basis alone.
Microneedling may be recommended separately where texture is the main concern. Laser treatment may address redness, pigmentation or texture depending on the modality used, but it does not recreate a missing anatomical feature. Camouflage products can provide immediate, temporary coverage, but require application by the user.
A medico-legal recommendation should therefore identify the particular component being treated. It should not imply that improvement in colour will also correct texture, restriction or symptoms.
Where medical tattooing sits within the pathway
Age, anatomical site, skin type, the original injury, complications during healing, repeated surgery
and individual healing all influence how a scar develops. Although the age of the scar is relevant, its appearance, stability and behaviour determine whether it is ready for medical tattooing.
Before medical tattooing, I am looking for relative stability. Is the colour still changing? Is the scar
raised, inflamed or symptomatic? Is further surgery being considered? Has laser treatment been
recommended but not yet completed? Is there a history that changes the risk profile? These questions determine readiness more reliably than age alone.
If laser treatment or surgical revision is likely to alter the surface, colour or boundaries of the scar,
it should be considered before medical tattooing because it may disturb implanted pigment or change the area requiring treatment. Where tissue is tight, adhered or hypersensitive, scar physiotherapy may be appropriate before tattooing. If the primary issue is persistent vascular redness, implanting skincoloured pigment is not the first answer.
The assessment may therefore lead to a direct medical tattooing plan, or to a recommendation
that another discipline assesses or treats the area first. Each expert remains within their own scope, while recognising where the work of another specialist may affect the timing or outcome of their recommendation.
What medical tattooing can reasonably achieve
Medical tattooing can reduce the contrast between a suitable scar and the surrounding skin. It can
recreate feature definition and symmetry, and it can make an area less immediately noticeable at
conversational distance. It cannot remove scar tissue, restore unscarred skin or guarantee that a
scar will no longer be visible.
A pale scar may blend extremely well. An irregular graft with colour and texture differences may
improve but remain recognisable. Fibrotic tissue may accept pigment less predictably. Implanted
pigment does not tan in the same way as the surrounding skin, so the relative colour may vary
when the surrounding skin tans. In my clinical experience, patients have not commonly reported this as a significant problem because the original contrast has already been reduced, but it remains
part of the maintenance discussion.
I explain the expected change in practical visual terms: reduced contrast, softened boundaries,
improved feature definition, or reduced prominence at conversational distance. I also state what the
treatment will not change.
The prognosis should also account for the risks and variability of treatment. Scar tissue may take up and retain pigment unevenly. The healed colour may not be an exact match, and fading or pigment migration can occur. Infection and inflammatory or hypersensitivity reactions are less common but recognised risks of tattooing.
These risks do not make an otherwise suitable treatment unreasonable, but they form part of assessing suitability and explaining the expected course.
The first course is not the lifetime cost
Medical tattooing is often described as permanent because pigment is implanted into the skin. The
pigment may remain present for many years, but the visual result is not maintenance-free. Its visible colour can soften or fade, while the scar and surrounding skin continue to change with sun
exposure and ageing. Further surgery or treatment may also alter the treated area.
A report that costs only the initial course maytherefore understate reasonable future need.
Equally, initial treatment and later colour maintenance should not automatically be treated as identical. The area will need to be reassessed at the time of a colour boost, and the treatment required will depend on pigment retention, changes within the scar and any treatment or surgery undertaken in the intervening period.
The assumptions behind any future allowance should be explained. Within my expertise, these include the area being treated, the initial number and duration of sessions, clinical intervals, anticipated pigment retention, likely colour-boost intervals, current fees and future assessment and treatment.
A practical example
Consider a composite example: a claimant with a lower-leg skin graft, a pale linear thigh donor-site
scar and a symptomatic scar across the knee. A single recommendation for ‘scar camouflage’ across all three areas would miss the clinical differences.
The graft may have mixed pigmentation, irregular texture and areas of fibrosis. It may be suitable for partial colour blending, but the likely result will depend on the proportion of hypopigmentation, the texture and the stability of the tissue. The donor site may be flat and hypopigmented, making it a more predictable candidate for medical tattooing. The knee scar may be pale but tethered and painful, so mobility, adherence and sensitivity may need assessment before colour becomes the priority.
The opinion may therefore contain three different pathways, three different timeframes and different levels of likely benefit. It may also conclude that one area should not be tattooed at all. The purpose of the assessment is to identify the treatment that is reasonable and clinically supportable, including
where treatment is not indicated.
Seven points the assessment should establish
• What precise aspect of the injury is this treatment intended to address?
• Why is this treatment appropriate for this claimant and this tissue?
• Is the area ready now; if not, what needs to happen first?
• Does another discipline need to assess or treat the area before this intervention?
• What improvement is realistically expected, and what will remain unchanged?
• How many appointments, over what period, and with what likely review or maintenance?
• What facts or assumptions could materially change the recommendation or cost?
The precise questions remain those set out by the instructing solicitor. Establishing these clinical
points allows me to answer those questions with a treatment plan and quantum figures that reflect the individual claimant rather than a standardised estimate.
Not suitable, not yet, or suitable within limits
A medical tattooing assessment does not always lead directly to a treatment schedule. Hyperpigmented scarring is not generally corrected by implanting more pigment, and some medical or dermatological factors may make treatment unsuitable. An active, unstable, inflamed or significantly raised scar may not be ready, while planned laser treatment or surgical revision may need to be completed first.
Where medical tattooing is suitable, the likely degree of change still needs to be explained. A
subtle or relatively low-contrast scar should not be dismissed on appearance alone. Objective visibility and personal impact are not the same: a scar that appears less prominent to an observer may still have considerable significance for the claimant. My role is to assess whether further visible improvement is achievable and describe the likely extent and limitations of that change, not to determine how much the scar ought to matter to the individual.
The opinion may therefore be ‘not suitable’, ‘not yet’, or ‘suitable with defined limitations’. That
distinction supports an appropriate treatment plan and gives the claimant a realistic understanding of what medical tattooing may achieve.
A clinically reasoned recommendation
Medical tattooing has a valuable place within medico-legal scar assessment, but not every scar
is suitable and not every suitable scar is ready for treatment at the time of assessment.
A specialist opinion should make clear which aspect of the scar medical tattooing can address, whether another assessment or treatment should come first, the likely degree and limitations of change, the anticipated number and spacing of sessions, and the probable need for future colour boosts.
For the instructing solicitor, this provides an individual, clinically reasoned future-treatment recommendation that is clear about what medical tattooing can and cannot achieve.
