Looking Beyond The Rash
If you've been living with eczema, dermatitis, psoriasis, hives or an unexplained itchy rash, you've probably already tried creams, steroid ointments or antihistamines that never answered the real question — why did the rash develop in the first place?
Since 1990, Douglas Mizzi has helped thousands of patients investigate the food, environmental, digestive and immune factors that may be driving ongoing inflammatory skin conditions.

Why Choose The Rash Clinic?
Many people with eczema, dermatitis, psoriasis, hives and chronic skin irritation spend years treating symptoms without ever discovering what may have contributed to those symptoms developing. At The Rash Clinic we take a different approach.
We begin by listening. We investigate your story. We explore your health history. We consider possible food and environmental triggers. We examine digestive health and immune function. Only then do we begin building your personalised recovery strategy.
Experienced Clinical Practitioner
Douglas Mizzi has worked in clinical nutrition since 1990 and has completed more than 65,000 consultations. His methodology has evolved through decades of clinical observation rather than textbook theory alone.
Looking Beyond The Rash
The rash is rarely viewed in isolation. Instead we investigate the person behind the symptoms — digestive health, clinical history, stress, food, environment, immune function, lifestyle. Everything contributes to the overall picture.
Personalised Recovery Plans
Every patient receives an individual strategy. There are no generic meal plans or one-size-fits-all programmes. Every recommendation is built around your personal history, symptoms and recovery goals.
Before You Try Another Cream...
Watch This First.
Douglas Mizzi explains why many chronic skin conditions may involve much more than simply treating the skin. Learn why detailed history taking, possible food and environmental triggers, digestive health and immune function all play important roles in understanding chronic inflammatory skin conditions.
Every Rash Has A Story
Our skin rarely changes without reason. Sometimes the cause may appear obvious. Often it isn't. Many patients tell us: "It just appeared."
When we carefully explore their history we frequently discover important events occurring months beforehand — stress, illness, antibiotics, major surgery, pregnancy, bereavement, relationship changes, digestive problems, food changes, environmental changes.
These observations do not automatically explain every rash. However they frequently provide valuable clues that help us better understand the bigger clinical picture.
The consultation is therefore less about looking at your skin... and more about understanding your story.
"We believe the body is usually trying to tell us something. Our role is to listen carefully enough to understand what it may be saying."

Why Patients Choose The Rash Clinic
After trying creams, ointments and short-term fixes elsewhere, patients come to us for a calmer, more thorough approach — one built on listening, experience and a genuine search for answers.
We Look For Causes, Not Just Symptoms
Rather than only calming the surface, we investigate the food, digestive, environmental and immune factors that may be driving your skin — including non-invasive food intolerance screening to help pinpoint likely triggers.
35+ Years Of Experience
Since 1990, Douglas Mizzi has completed more than 65,000 consultations, refining a careful, methodical way of working through complex cases.
Time To Be Heard
Your history matters. We take the time to understand your full story instead of rushing you through a five-minute appointment.

Skin Conditions We Commonly Help Investigate
Eczema
Many people living with eczema spend years managing flare-ups without understanding why they continue to occur. Our investigations may explore possible food triggers, immune health, digestive function, stress and clinical history.
Learn MoreDermatitis
Dermatitis often develops for multiple reasons. Rather than assuming a single cause, we investigate your history, environment, diet and immune health to better understand possible contributing factors.
Learn MorePsoriasis
Psoriasis represents one of the more complex inflammatory skin conditions we encounter. Our consultations aim to understand the wider health picture while providing practical nutritional and lifestyle guidance.
Learn MoreHives & Urticaria
Recurring hives can be both physically uncomfortable and emotionally exhausting. Our approach investigates possible food, environmental and historical factors while helping patients understand their individual pattern.
Learn MoreChildhood Skin Conditions
Children frequently present differently to adults. Our consultations consider pregnancy history, early childhood development, antibiotic exposure, family history, dietary patterns and environmental influences.
Learn MoreUnexplained Rashes
Not every rash fits neatly into a medical category. When patients tell us "no one knows why" — we begin asking different questions. Understanding the story often becomes the starting point.

Food May Be Part Of The Story
Many patients arrive believing food has nothing to do with their skin. Others believe food explains everything. Our experience suggests the truth often lies somewhere in between.
Food represents one potential contributor among many. During your consultation we investigate the complete picture.
Sometimes The Story Begins Long Before The Rash
One question Douglas has asked thousands of patients over more than three decades is remarkably simple: "What was happening in your life before this began?"
Many people immediately begin remembering events they had never connected with their health — the loss of a loved one, relationship breakdown, financial stress, major surgery, family conflict, or long-term emotional pressure.
What Was Happening Before Your Rash Appeared?
Our consultation begins by reading the earlier chapters first.
"We are often less interested in the rash itself than we are in the months leading up to the rash."
Douglas Mizzi
We Treat People...
Not Just Skin.
Every person has a different story. Every family has different circumstances. Every immune system has travelled a different path.
That is why no two recovery plans are identical. Our role is not to fit you into a protocol. Our role is to understand your individual journey and help you move forward with greater confidence.
Experience You Can Trust.
A Methodology You Can Understand.
