Rashes & Spots
A rash is any area of irritated or swollen skin, often itchy, often painful, and appearing differently on different skin tones. We diagnose and treat a wide range of rashes and spots, with the full range of investigations available when the diagnosis is uncertain.

Our approach
The right diagnosis first.
Our approach starts with a thorough evaluation to ensure an accurate diagnosis, distinguishing between skin conditions with similar presentations: syringomas, Fordyce spots, milia and others. Where a rash is more challenging or uncertain, further investigation may be needed, and we provide a full range of investigations to support diagnosis and management.
Recurrent rashes usually mean the diagnosis is incomplete. A full range of investigations is available here to establish what is actually driving it.
Recurrent or unexplainedRashes are often itchy and painful, and appear differently on different skin tones. Treatment is chosen to control the cause, not only the symptom.
Itching & discomfortYour plan may include topical or oral medication, or a combination with procedures: laser, peels, LED, injectables, supplements or skincare.
Failed treatmentSmall bumps are frequently misidentified. Our evaluation separates syringomas from Fordyce spots, milia and similar presentations before treatment.
Look-alike spotsWhat we treat
Four conditions.
Eczema treatment
Eczema, also known as atopic dermatitis, is a chronic skin condition in which patients experience inflammation and intense itching. It often appears as dry, red and scaly patches on the skin.
Psoriasis treatment
A chronic autoimmune disease affecting the skin, leading to rapid skin cell turnover and a build-up of thick, scaly patches that vary in severity and location. Commonly red, raised and covered with silvery scales, usually with itching and pain.
Urticaria treatment
Urticaria, or hives, shows up as itchy, raised bumps or welts on the skin, often triggered by allergic reactions to foods, medications or environmental factors. Hives can appear out of nowhere, usually with redness and sometimes swelling.
Age spots & freckles
Pigmentation concerns caused by overactive melanocyte cells in response to sun exposure. Freckles typically appear as small, light brown spots and are more common in younger individuals; age spots develop over time and are often larger and darker.
Any skin rash
We offer consultation and treatment for any skin rash. Where the presentation is uncertain, further investigation is arranged before a plan is set.
“Two rashes can look identical and need opposite treatments. That is why the investigation comes before the prescription, not after it fails.”
How we treat
Tailored to each patient.
The best treatment plan is tailored to meet each patient's needs, and may include prescription of topical or oral medication, or combination treatment with procedures.
Topical or oral medication prescribed by a consultant dermatologist, where that is what the diagnosis calls for.
Procedural treatment used in combination with medical management where it will help.
Used as part of a combination plan for specific inflammatory and pigmentary presentations.
Oral supplements and skincare chosen to support the plan and maintain the result between visits.
