Vitiligo is one of the most common conditions we see at this clinic. Over the past three decades, I have treated thousands of patients with this condition, and the single most important thing I can tell you is this: vitiligo is treatable, and early intervention makes a significant difference.
What Is Vitiligo?
Vitiligo occurs when melanocytes — the cells that produce the pigment giving your skin its colour — are destroyed by the body's own immune system. The result is well-defined white patches that can appear anywhere on the body. It affects roughly 1-2% of the global population, with a slightly higher prevalence in India.
It is not contagious. It is not caused by something you ate. It is not a punishment. These are myths I have spent my career correcting, and they cause more suffering than the condition itself.
What Causes It?
The precise trigger remains under investigation, but we know it involves an autoimmune mechanism. The body's T-cells mistakenly attack melanocytes. Genetic predisposition plays a role — about 20% of patients have a family member with vitiligo or another autoimmune condition such as thyroid disease.
Common triggers that can initiate or worsen vitiligo include physical trauma to the skin (the Koebner phenomenon), severe emotional stress, sunburn, and exposure to certain industrial chemicals. This is why I ask every new patient about their occupation, recent stresses, and whether they have noticed patches appearing at sites of injury.
How We Treat Vitiligo at Our Centre
Our approach has always been conservative and systematic. We begin with a thorough clinical examination and may order blood tests to check for associated conditions — particularly thyroid disorders, vitamin B12 deficiency, and diabetes.
Topical therapy forms the backbone of treatment. For facial patches, we prefer tacrolimus ointment (a calcineurin inhibitor) because it avoids the skin-thinning risks of steroids on the face. For body patches, measured courses of topical corticosteroids remain effective. We combine this with oral mini-pulse therapy — small, intermittent doses of corticosteroids — to halt the progression of active vitiligo.
Sunlight exposure is a natural ally. We guide patients on safe, timed morning sun exposure to stimulate melanocyte activity in the affected areas. This is not a substitute for medication but a powerful complement.
What to Expect
Repigmentation begins as small brown dots (perifollicular repigmentation) appearing within the white patches. This typically starts within 2-3 months of consistent treatment, with significant improvement by 5-6 months. Facial patches respond fastest; fingers and toes take longer.
Patience is not optional — it is part of the treatment. The patients who do best are those who follow their regimen consistently, attend follow-ups, and understand that this is a marathon, not a sprint.
When to See a Dermatologist
If you notice any new white patch on your skin — especially if it is expanding — consult a dermatologist promptly. The earlier treatment begins, the better the outcome. Do not wait for the patches to become large, and do not waste time on unproven home remedies.
