Pigmentation, redness, and texture issues all have different causes. Learn what’s happening beneath the skin, and why VISIA analysis helps diagnose it properly.

Patients often come to the clinic, describing frustrations like:
“My skin tone looks uneven.”
“I have red patches or broken veins.”
“My pores look large.”
“My skin just looks blotchy or tired.”
These concerns are incredibly common and often grouped under vague terms like “bad skin”, “sun damage”, or “sensitivity”. But in reality, pigmentation, redness, and texture are driven by different biological processes, each with its own causes and treatment pathways.
This is where modern skin imaging and diagnostics become essential. Without understanding the underlying problem, patients end up wasting money on products or treatments that simply aren’t designed for the issue they’re trying to fix.
Let’s break down what’s really happening beneath the surface.
Pigmentation refers to excess melanin in the skin, the pigment that gives skin its colour. Common forms include:
Sunspots/sun damage
Freckles (ephelides)
Melasma
Post-inflammatory hyperpigmentation (PIH)
The primary drivers include:
UV exposure
Triggers melanocytes to produce pigment as protection.
Hormonal changes
Common in melasma (pregnancy, OCP use).
Inflammation
Acne or injury can trigger pigment as it heals (PIH).
Genetics
Some skin types produce pigment readily.
Two patients may look similar to the naked eye, but have:
Epidermal pigment (more superficial)
Dermal pigment (deeper)
Mixed melasma (both)
Inflammatory PIH
UV-induced lentigines
They require different treatments. VISIA’s UV analysis helps distinguish surface vs subsurface pigment, something that’s almost impossible to diagnose accurately by eye alone.
Redness is driven by blood vessels, not pigment. Common forms include:
Flushing
Broken capillaries (telangiectasia)
Diffuse background redness
Rosacea
Post-inflammatory erythema (PIE)
Key drivers include:
Sun exposure
Genetic vascular sensitivity
Rosacea
Sebaceous activity
Inflammation
Heat, exercise, alcohol
Compromised barrier function
This is why patients often say:
“My skin gets red easily,” or
“I look flushed even when I’m calm,” or
“I have visible veins around my nose.”
Redness is often mistaken for:
Sensitivity
Allergy
Sunburn
Pigmentation
Acne
But vascular and pigment problems are entirely different, a key reason patients frequently waste money on the wrong products.
VISIA’s RBX® analysis isolates brown vs red channels, allowing accurate mapping of vascular vs pigment components.
Texture issues include:
Roughness
Fine lines
Acne scarring
Pore visibility
Surface irregularities
exture is influenced by:
Collagen degradation
Elastin loss
Oil production
Inflammation
Ageing-related thinning
Cellular turnover
As we age, collagen production slows, and the dermal scaffolding weakens, causing:
Larger-looking pores
Less reflective skin
Fine lines and creasing
Rough or uneven patches
Texture problems are structural, not pigment-based, so they require different approaches.
Skincare can improve:
Barrier function
Hydration
Inflammation
Pigment suppression
Antioxidant protection
But it cannot:
Close blood vessels
Break down accumulated pigment
Remodel collagen
Reverse UV injury in the dermis
This is why correct diagnosis is crucial, so patients don’t try to “treat redness with vitamin C” or “treat melasma with exfoliation”, etc.
The VISIA® Skin Analysis System offers objective data on:
Brown pigmentation
UV damage
Redness & vascularity
Texture & pores
Bacterial porphyrins
Wrinkles & collagen markers
True Skin Age
A VISIA scan reveals the dominant issue, so treatment plans are rational rather than speculative.
For example:
Patient thinks it’s “pigment” → VISIA shows vascular rosacea
Patient thinks it’s “dryness” → VISIA shows dermal UV damage
Patient thinks it’s “sensitivity” → VISIA shows inflammatory redness
Patient thinks it’s “large pores” → VISIA shows collagen degradation
This is where diagnosis saves time, money, and frustration.
Pigmentation, redness, and texture issues may all look similar at first glance, but they are driven by different biological mechanisms. Treating them effectively starts with understanding what’s actually happening beneath the skin.
Objective imaging, like VISIA, makes that possible, and empowers patients to pursue treatment pathways tailored to their skin’s real needs.

And this is why HA fillers have never gone out of fashion in our practice!
This lovely patient had all the classic signs of volume loss in her face and there is no other non-surgical treatment that can address this quite as quickly, effectively and non-invasively as HA filler. Of course, it needs to be carefully and sensitively applied.
This patient had a total of 10mls of HA as well as some wrinkle relaxing on the upper face. She is delighted with her restoration. What do you think?
Upper eyelid surgery isn’t just for ageing eyes! Some patients naturally have excess upper eyelid skin from a young age due to their anatomy, like this 29-year-old patient who had a congenital upper eyelid fold and recently underwent an upper blepharoplasty with the ever-talented @bramhallplasticsurgery.
The excess eyelid skin rested directly on her eyelashes, causing irritation and a persistent feeling of heaviness around the eyes which had been bothering her for several years. Upper eyelid surgery can address both functional symptoms and aesthetic concerns, helping patients achieve a lighter, more open eye appearance.
This patient is just 7 weeks after surgery. At this early stage of healing the scars are still maturing and in younger patients this process can take slightly longer. The incision is placed within the natural eyelid crease and as healing progresses the scar typically fades and becomes extremely difficult to see, often blending into the natural eyelid fold.
She`s delighted with the results so far, and we`re grateful to her for allowing us to share her results with you.

Thank you once again to another lovely patient who has allowed us to share her photos with you.
She came to see me wanting a refresh and was open to suggestions, surgical and non-surgical. Her biggest concern however was wrinkles and lines and skin texture problems.
Surgery doesn’t help with this and injectables are limited too - the gold standard here is laser resurfacing, which is what we went with. We did a full field ablation of the full face including her eyelids.
This is her a month or so later. You can see she is still a bit red, especially around the eyes where we went the deepest, but she is already loving life with her new skin.

The non-surgical facelift!
You might have heard us talking a lot recently about combination treatments, using different treatment modalities to create synergy in non-surgical rejuvenation. The reason this works so well is that the different layers of the face age in different ways.
We focus a lot on skin tightening, which is super important, but that’s only the outer layer of the face. Below that the fat, bone and muscle are all changing too.
This lovely lady was relatively new to aesthetics and wanted a more comprehensive rejuvenation without surgery. We decided to do the combination approach using @sofwave.uk to tighten the skin of the face and neck, whilst using HA to restore volume to the fat and bone.
This is her a few months later - her whole face looks tighter, softer, less tired - but in a way that looks completely natural. She is delighted with the result that still looks like her, just a really refreshed version.

HA Fillers are making a comeback! Here are my thoughts on the how and why 👀
How long does a facelift last? One of the most common questions we hear, but it doesn’t have a straightforward answer. Here is our facelift expert @bramhallplasticsurgery talking about some of the nuance.
I’ve been getting lots of questions about what I’ve been up to with my own skin recently. So here you are… the full uncensored version 👀
Introducing Julaine - a new biostimulator I am very excited about!
To explain the background, we need to start with Sculptra - which is having a bit of a moment again on socials. Sculptra is made of PLLA which stimulates your own body to create more collagen, which sounds instantly appealing especially for patients who want to avoid HA fillers.
The problem is that 1 in 5 people who have Sculptra develop nodules which is why - despite the beautiful results we often see from it - I have never used it in my practice (at least not in the face). The trade off in terms of the risk of nodules is just too high for me to feel comfortable with.
We now have a new version, called Julaine, made from a Swedish company called Nordberg. The scientists at Nordberg have refined the manufacturing process to make the PLLA particles smaller and smoother and in doing so have eliminated the problems associated with Sculptra.
I have only just recently started working with Julaine (it’s been around for a couple of years now, but I never like to be the first to use it - I always want to make sure the real world data matches up to what the pharma companies tell us). The treatment is delivered over three sessions, one month apart, with gradual tissue regeneration and volumising occurring slowly over time.
The course of 3 sessions costs £3000 and results typically last up to 2 years. It’s a great addition for other regenerative treatments like Sofwave skin tightening. It’s also great for patients who’ve had HA fillers and feel like they need something else, but aren’t quite ready for more HA yet.

One of Dr Kavita’s breast reduction patients sent this gorgeous bouquet of flowers after her follow up - simply because she felt so grateful for her result and the care our team provided.
Moments like this remind us why we do what we do and why ‘how’ we do it is so important. Surgery has traditionally been a very male-dominated world, but Kavita brings something different - exceptional technical skill combined with empathy, warmth and a genuine understanding of women’s bodies and aesthetics.
There can be a lot of pressure on women in surgery to abandon their femininity to fit in. Kavita hasn’t done that. She’s succeeded by being completely herself.
And that’s exactly why our patients love her (and why we do too).
We’re very proud to have her as part of the McKeown Medical team.
