Canfield Imaging uses the VISIA and VISIA-CR systems to capture detailed, objective measurements of acne scars before treatment, allowing dermatologists to quantify scar location, color, shape, size, and depth with precision. Rather than relying solely on visual assessment, these FDA-approved imaging systems produce standardized photographs and 3D topographical data that form the foundation of an evidence-based treatment plan. This article explains how Canfield imaging technology works, why it matters for scar assessment, and how practitioners use these measurements to select and track the most effective treatments for individual patients. We’ll also cover the specific capabilities of different VISIA systems, real limitations of the technology, and how objective data changes the treatment planning process.

How VISIA Technology Captures the True Picture of Acne Scarring
The visia Complexion Analysis System works by using multiple light sources—standard white light, cross-polarized flash, and UV photography—to capture the skin surface from different angles and under different lighting conditions. This multi-spectral approach reveals details that the human eye alone cannot see. For example, when assessing a patient with mixed ice pick scars and rolling scars on the cheeks, white light photography shows overall appearance, but cross-polarized images isolate subsurface pigmentation and vascular changes, while UV photography highlights any hidden inflammation or bacterial activity in scar tissue. The system also includes RBX® technology, which separates and visualizes the unique color signatures of red and brown skin components.
This is particularly useful when evaluating acne-prone skin or post-inflammatory hyperpigmentation that often accompanies scarring. By isolating these color signatures, the imaging system can distinguish between active acne lesions, post-inflammatory marks, and permanent structural scars—a distinction that changes which treatments are appropriate. A patient seeing faded red marks may think they’re permanent scars, but VISIA imaging can confirm whether those marks are actually healing inflammation rather than true scarring, potentially avoiding unnecessary aggressive treatments. FDA approval and CE marking of the VISIA system means the imaging data is suitable for clinical studies, regulatory submissions, and treatment efficacy claims. This regulatory backing gives practitioners and patients confidence that the measurements aren’t arbitrary but follow standardized protocols.
3D Topography and Micron-Level Scar Depth Measurement
The VISIA-CR system adds a critical dimension that standard 2D photography cannot provide: three-dimensional topographical analysis using PRIMOS 3D capture technology at micron-level resolution. This means the system can measure scar depth down to the micrometer scale, producing a detailed topographical map of the skin surface. For a patient with boxcar scars—sharply defined, deeper indentations—this 3D data quantifies exactly how deep the scar extends beneath the surrounding skin, information that is essential for deciding whether subcision, dermal fillers, laser resurfacing, or a combination approach is needed. This objective depth measurement becomes particularly important when comparing treatment options.
A boxcar scar measuring 0.8 millimeters deep might respond well to fractional CO2 laser alone, while a scar measuring 2.5 millimeters deep might require subcision first to break fibrous adhesions before laser treatment. Without this measurement, the choice is based on subjective judgment. With it, the treatment plan is grounded in specific anatomy. However, if a patient has severe scarring across a large area, the cost and time required for detailed 3D imaging of the entire affected region may be impractical, so practitioners often prioritize imaging of representative scars or the most bothersome areas.
Automated Acne Lesion Evaluation and Clinical Validation
Recent research published in the Journal of Drugs in Dermatology demonstrated that VISIA-CR imaging can automate acne evaluation, automatically counting and classifying acne lesions with high correlation to manual physician assessment. This automation removes subjectivity from the counting process. Two dermatologists might visually count 23 lesions on a cheek, while a third counts 28; the VISIA-CR system provides a consistent, reproducible count that can be tracked across follow-up visits. For clinical trials testing new acne treatments or for practices documenting treatment response, this consistency is invaluable.
In a notable clinical study examining acne scars treated with poly-L-lactic acid injection, researchers used VISIA imaging to assess scarring outcomes. The study noted that VISIA “provided the most detailed imaging of skin topography” available, enabling precise measurement of scar improvement after treatment. This level of documentation protects both patient and practitioner: the before-and-after measurements provide concrete evidence of what the treatment accomplished, rather than relying on subjective impressions. A patient who feels their scars improved gets objective confirmation; a patient who doesn’t see results has data showing whether the treatment actually changed the scar structure.
Using Imaging Data to Select the Right Treatment
Once a practitioner has detailed VISIA imaging of acne scars, that data directly informs treatment selection. The system provides objective measurements to assist with patient screening—determining who is a good candidate for specific treatments—and documenting efficacy claims for treatment outcomes. For instance, a patient with severe rolling scars (wide, undulating depressions) combined with boxcar scars requires a different approach than someone with only superficial ice pick scars. The VISIA-CR data showing the depth profile of each scar type guides the choice between laser resurfacing strength, the number of subcision passes needed, or whether dermal fillers should be part of the plan.
The imaging also helps set realistic expectations. A patient might hope that one laser treatment will completely erase their scars, but the 3D topographical data shows scars extending 1.5 millimeters deep in some areas. The practitioner can show the patient that depth and explain that one laser session typically resurfaces only 50-100 micrometers of skin, meaning multiple treatments or combination therapies will be necessary. This transparency, backed by objective measurements rather than assumptions, improves patient satisfaction because expectations are grounded in actual scar anatomy rather than hope. However, even with perfect imaging data, practitioner skill and patient healing response still heavily influence outcomes—imaging shows what needs to be treated but doesn’t guarantee any specific result.
Limitations of Imaging: What VISIA Cannot Do
While VISIA imaging is highly detailed, it has important limitations that practitioners must understand. The system measures the current state of scars but cannot predict how a patient’s skin will respond to treatment, nor can it measure factors like skin elasticity, the degree of fibrous adhesion deep within the dermis, or the patient’s healing tendency. A 1-millimeter-deep scar in a patient with strong elasticity might improve dramatically with subcision and simple fractional laser, while the same depth scar in a patient with poor wound healing might stubbornly persist even after aggressive treatment. The imaging shows the scar’s architecture but not these biological variables.
Additionally, VISIA imaging works best on lighter to medium skin tones; on very dark skin, the system’s ability to detect color differences and subtle variations may be reduced. Some practitioners supplement VISIA imaging with manual tactile assessment—literally feeling the scar with their fingers—to detect adhesions and depth that imaging alone might miss. And while 3D topography is precise, the resolution and reproducibility depend on positioning the skin identically at each scan; if a patient is not positioned the same way at follow-up visits, comparing before-and-after measurements becomes unreliable. This is why practices using VISIA for treatment tracking must maintain rigorous positioning protocols.
Before-and-After Treatment Tracking
Perhaps the most practical application of Canfield imaging is objective tracking of treatment response over time. After a patient completes subcision, laser resurfacing, or other scar treatments, follow-up VISIA imaging at 3 months and 6 months shows whether the scar depth has decreased, whether color changes have improved, and whether the treated area is tracking toward expected outcomes. Rather than asking “Do you think your scars look better?”—which is subjective and subject to bias—the practitioner can show side-by-side 3D topographical maps proving that scar depth has reduced from 1.2 millimeters to 0.7 millimeters.
For example, a patient undergoing subcision for rolling scars followed by fractional CO2 laser at 4 weeks would receive VISIA imaging at baseline, immediately after the laser treatment, at 3 months, and potentially 6 months to document the healing and remodeling process. The imaging data shows not just that the patient feels better but that the scar structure is actually changing. This documentation also becomes valuable if the patient pursues additional treatments elsewhere or if there are any complications that need to be evaluated objectively.
The Direction of Acne Scar Assessment Technology
Canfield continues advancing its imaging systems toward fuller automation and AI integration. The movement toward systems like VISIA-CR that automate counting, measurement, and classification reflects a broader trend in dermatology toward objective, quantifiable assessment. As algorithms improve and imaging systems become faster and more user-friendly, practices that weren’t previously using objective imaging may adopt it.
This shift benefits patients because it removes guesswork from treatment planning and creates a documented standard for measuring whether treatments are actually working. At the same time, imaging technology is not replacing clinical judgment—it’s supporting it. A dermatologist with 20 years of experience who knows how different scar types typically respond to various treatments will always be necessary. What VISIA imaging does is give that expertise a foundation of objective data, reducing the room for error and providing documentation that protects both practitioner and patient.
Conclusion
Canfield Imaging, particularly the VISIA and VISIA-CR systems, has fundamentally changed how dermatologists approach acne scar assessment and treatment planning. By providing FDA-approved, objective measurements of scar location, depth, color, and volume down to micron-level precision, these systems move scar evaluation from subjective visual judgment to documented, quantifiable data. This matters for selecting the most appropriate treatment, setting realistic patient expectations, and objectively tracking whether treatments are actually improving scars over time.
If you’re considering treatment for acne scars, asking whether your dermatologist uses objective imaging like VISIA is a reasonable question. Practices using these systems have data to back up their treatment recommendations and can show you exactly what they’re targeting and how the treatment is progressing. Even if your practice doesn’t use Canfield’s specific equipment, the principle of objective measurement—whether through photography, 3D scanning, or other means—should inform your treatment plan. Combine that objective data with your practitioner’s clinical experience, and you have the best foundation for an effective scar treatment strategy.
Frequently Asked Questions
Does every dermatology practice use Canfield imaging for acne scar assessment?
No. While VISIA systems are widely used, particularly in dermatology offices and aesthetic practices, not all providers use objective imaging. Many practitioners assess scars visually and manually feel them to determine depth and treatment approach. However, if a practice is documenting treatment outcomes for legal or marketing purposes, objective imaging is becoming standard.
Can VISIA imaging work on all skin types?
VISIA performs most reliably on lighter to medium skin tones. On very dark skin, detecting color differences and subtle variations can be more challenging. If you have darker skin, ask your practitioner whether they’ve used VISIA on similar skin types and whether they supplement it with tactile assessment.
How much does VISIA imaging add to the cost of a scar assessment?
Costs vary by practice. Some dermatologists include baseline imaging as part of the consultation; others charge a separate imaging fee. The cost typically ranges from $50 to $300 for imaging at baseline and follow-up. Given that it directly informs treatment selection and documents outcomes, many patients find it worthwhile.
How often should scars be re-imaged during treatment?
This varies depending on the treatment type and timeline. A typical protocol might include baseline imaging, immediate post-treatment imaging, imaging at 3 months (when initial healing is complete), and imaging at 6 months (when full remodeling has occurred). More frequent imaging is unlikely to show useful changes and increases costs.
Can VISIA imaging predict how my scars will respond to treatment?
No. VISIA shows the current structure of your scars but cannot predict your individual healing response, skin elasticity, or how your body will remodel treated tissue. It guides treatment selection but doesn’t guarantee specific outcomes.
What’s the difference between VISIA and VISIA-CR?
VISIA is the standard complexion analysis system using multiple light sources and 2D photography. VISIA-CR adds 3D topographical measurement (the CR stands for Complexion and Reflectance), enabling precise depth and volume measurements. VISIA-CR is preferred for detailed scar assessment but is more expensive and may require longer appointment times.
