VISIA

The system captures your face in three different lighting modes, each revealing something the others cannot.

Standard lighting records what you see in the mirror. Cross-polarised light cuts through surface reflection to show what is happening within the skin, which is how it separates redness and pigmentation from skin texture. Ultraviolet light reveals damage sitting below the surface that is invisible in ordinary light, including sun damage accumulated years before it becomes visible.

Canfield's RBX technology then separates the red and brown components of your skin colour, so vascular concerns and pigmented areas can be assessed independently rather than being read as one general unevenness. That distinction matters, because redness and pigmentation need entirely different treatments.

The eight features VISIA measures

• Spots. Brown or red marks visible on the surface, including blemishes and post-inflammatory marks.
• Wrinkles. Furrows, wrinkles and fine lines resulting from sun exposure and the gradual loss of collagen and elasticity, measured rather than estimated.
• Texture. Skin texture and surface irregularity, including scarring and areas of roughness or flaking.
• Pores. Size and density of visible pores across the face.
• UV spots. Melanin damage below the surface, caused by sun exposure and not yet visible to the eye. For most patients this is the most striking image of the session.
• Brown spots. Pigmentation on and beneath the surface, mapped as distinct pigmented areas rather than general unevenness, including melasma and age spots.
• Red areas. Concentrated redness that can indicate inflammation, skin sensitivity, acne or thread veins.
• Porphyrins. Bacterial by-products lodged in pores, which contribute to congestion and breakouts.

Alongside the individual measurements, VISIA produces a TruSkin Age: an assessment of how old your skin appears based on its measured condition, drawn from one of the largest skin feature databases in existence.

Each of the eight features is also expressed as a percentile against people of the same age and skin type. That is more useful information than a raw score. Knowing you sit in the top quarter for skin texture but the bottom quarter for UV damage tells you exactly where effort is worth spending, and where it is not.

The analysis is a starting point rather than a treatment in itself, and it changes conversations in three ways.

It shows you what you cannot see. The UV image is often the moment something clicks. Patients who describe their sun exposure as minimal frequently have significant subsurface damage, and seeing it tends to do more for daily SPF habits than any amount of advice.

It directs treatment planning. Redness, pigmentation, texture and congestion respond to different things, and the analysis makes clear which is the dominant concern. It informs whether laser resurfacing, a vascular laser, RF microneedling or a change of medical-grade skincare products is the right first step, and in what order. Sometimes the answer is that cosmetic treatments should wait while we repair the skin barrier first.

It measures progress. Skin improves slowly, and people are poor judges of gradual change in their own faces. Repeating the analysis after a course shows what has moved, and occasionally shows that something is not working, which is worth knowing early. Measuring rather than assuming is what improves patient outcomes over time.

Who it suits

A VISIA analysis is useful for most patients, but it earns its place in three situations in particular.

If you are starting a course of treatment, it gives you a baseline to measure against. If you are younger and thinking preventatively, it shows where damage is already accumulating while there is still time to act on it. And if you have tried things that have not worked, it often explains why, because a skincare routine aimed at the wrong skin concerns rarely helps.

It is not suitable if you cannot remove all make-up before the session, since the imaging measures your skin rather than what is on it. We will ask you to arrive with a clean face, or allow time to cleanse at the clinic.

The scan itself takes only a few minutes. You rest your chin in the imaging booth, the system captures your face in each lighting mode from a fixed position, and the analysis is generated immediately.

The valuable part is what follows. Your aesthetician or nurse will take you through each of the eight features, explain what the images are showing, and translate the numbers into personalised treatments and a personal care routine that suits your skin. You will leave with information you can act on rather than a printout you never look at again.

In our experience, the analysis is most valuable carried out alongside a skin consultation, or before looking at skincare options, so the recommendations that follow are grounded in what the imaging actually found.
