Have you ever seen someone with irregular white patches on their skin?

These patches can appear on the face, arms, neck, or even across the entire body. They’re typically neither painful nor itchy, but they can be confusing and sometimes distressing. This condition is likely to be vitiligo, a common skin disorder characterised by a loss of pigment. While vitiligo is neither contagious nor life-threatening, it can have a significant impact on a person’s psychological wellbeing, social life, and overall quality of life.
Today, let’s take a closer look at what vitiligo is, its causes, symptoms, treatment options, and daily care tips.

What is Vitiligo?

Vitiligo is a condition where the melanocytes – the pigment-producing cells in the skin – become damaged or inactive, resulting in white patches. These patches usually have clearly defined edges and contrast sharply with the surrounding skin.

Common signs of vitiligo include:

• White patches on the skin – usually symmetrical, with smooth surfaces and well-defined borders.
• Typical areas affected: face, backs of the hands, fingers, arms, knees, feet, lips, and genitals – especially areas that are exposed or frequently subject to friction.
• Hair turning white – in some cases, hair growing in the affected areas may also lose its colour.

Is Vitiligo Contagious or Hereditary?

There is a genetic component.
Vitiligo tends to run in families, though it is not strictly hereditary. Even if a parent has vitiligo, their child may not necessarily develop it. However, when combined with environmental or immune-related factors, the risk of developing vitiligo may increase.

Vitiligo is not contagious.
It is not caused by a virus or bacteria, and cannot be spread through physical contact, the air, or water.

What Causes Vitiligo?

The exact cause of vitiligo is still not fully understood, but it is generally believed to result from a combination of factors, including:

1. Autoimmune factors: the immune system mistakenly attacks and destroys melanocytes.
2. Genetics: a family history may increase the risk.
3. Skin trauma or friction: repeated friction, pressure, or sunburn can potentially lead to localised depigmentation.
4. Psychological stress: chronic stress, anxiety, or depression may trigger or worsen the condition.
5. Nutritional deficiencies: low levels of elements such as copper and zinc, which are important for melanin production.

Can Vitiligo Be Treated?

Vitiligo treatment can be a long-term process. While there is no one-size-fits-all “cure”, many patients see significant improvement – including repigmentation and even clinical remission – with appropriate treatment.

Common treatment options include:

1. Topical medications – corticosteroid creams, calcineurin inhibitors like tacrolimus, and photosensitisers to stimulate melanin production.
2. Phototherapy – narrowband UVB (311nm) light therapy and excimer laser therapy are established treatments that promote the regeneration of pigment cells.
3. Oral medications – prescribed in some cases to support treatment.
4. Surgical options – such as skin grafting or melanocyte transplantation, may be considered for localised and stable cases, but require careful evaluation.

Traditional Chinese Medicine (TCM) Approach:

In TCM, treatment is personalised based on individual constitution. Internal herbal medicine, external topical applications, and acupuncture may be combined to rebalance the body, reduce the spread of white patches, and alleviate the emotional stress that can exacerbate symptoms.

Lifestyle Tips and Daily Care:

1. Avoid excessive sun exposure – UV radiation can damage pigment cells and may worsen the condition.
2. Minimise friction or skin trauma – avoid tight clothing and frequent scratching.
3. Manage stress and emotions – mental wellbeing plays a key role; keeping calm and relaxed is beneficial.
4. Maintain a balanced diet – include foods rich in copper, zinc, and vitamins B, C, and E.
