John C. Su is a dermatologist based in Box Hill, VIC, Australia. He helps people with skin problems that can be itchy, sore, or just plain worrying. Skin issues can change day to day, and he works with patients to make a clear plan that fits real life.
As a skin doctor, John sees many types of conditions. In many cases, that includes eczema and atopic dermatitis, where the skin gets dry, red, and very itchy. He also looks after people with contact dermatitis, including reactions from things like workplace exposures, products, or fabrics.
John treats long-term and more complex skin conditions too. This can include blistering disorders such as epidermolysis bullosa, including different forms like dystrophic epidermolysis bullosa and junctional epidermolysis bullosa. People may also come in with bullous pemphigoid, where blisters can form and the skin may feel tight or painful.
He commonly helps with inflammatory skin problems such as psoriasis and plaque psoriasis, plus pustular and other ongoing rash conditions. Hives, also known as urticaria, are another issue he deals with, especially when the triggers are not obvious.
Infection and irritation can be part of the story as well. John sees people with scabies and other skin infections, including impetigo. At times, he also helps families with birthmarks and skin growths, like hemangiomas, and other skin conditions present from early life.
Some referrals relate to skin and immune conditions. For example, he can help with cutaneous lupus erythematosus (CLE) and discoid lupus erythematosus (DLE), where rashes show up on the skin and need careful treatment.
John also understands that skin symptoms often link with allergies. He works with patients who have related issues such as allergic rhinitis, asthma, or occupational asthma. Even when the main concern is skin, the wider picture matters, and he tries to keep it simple and practical.
John’s clinic approach is calm and straightforward. Over time, he helps people learn what to watch for, how to use treatments safely, and what to do if things flare up again. If you’re not sure what’s causing the problem, he can help sort it out and guide you toward next steps.
