Vitiligo (White Patches on Skin): Causes, Treatment Options and What to Expect
By Dr Lim Tzyy Huei | Consultant Dermatologist, Pantai Hospital Batu Pahat, Johor, Malaysia
Vitiligo is a skin condition that causes white patches to develop on different parts of the body, commonly affecting the face, hands, arms and legs.
For some people, the patches remain unchanged for many years. Others may notice new patches developing or existing ones gradually spreading.
Although vitiligo is not contagious or life-threatening, its visible appearance can sometimes affect self-confidence and emotional well-being.
Treatment is available to help control disease progression and restore some of the lost skin colour. However, improvement takes time, and results vary between individuals.
Understanding the condition, available treatments and realistic expectations can help patients make informed decisions about their care.
What Is Vitiligo?
Vitiligo occurs when pigment-producing cells in the skin, called melanocytes, are damaged or destroyed.
These cells produce melanin, the pigment responsible for natural skin colour. When melanocytes are lost, affected areas become lighter or completely white.
Vitiligo can affect almost any part of the body, including:
Face, particularly around the eyes and mouth
Hands and fingers
Arms and legs
Feet
Genital areas
Scalp and hair
Some patients develop only a few small patches, while others experience more widespread involvement.
What Causes Vitiligo?
Vitiligo is primarily an autoimmune skin condition, meaning the immune system mistakenly attacks the body's own pigment-producing cells.
Several factors may contribute to its development.
1. Genetic predisposition
Having a family member with vitiligo may increase the likelihood of developing the condition, although many patients have no family history.
2. Autoimmune activity
Vitiligo can occur alongside other autoimmune conditions, particularly autoimmune thyroid disease.
3. Skin injury or repeated friction
In some patients, scratching, rubbing, pressure or skin injury may trigger new white patches. This is known as the Koebner phenomenon.
4. Environmental factors
Sunburn and certain chemical exposures may contribute to the development or worsening of vitiligo in susceptible individuals.
Importantly, vitiligo is not caused by poor hygiene and cannot spread from one person to another.
Will Vitiligo Continue to Spread?
The progression of vitiligo varies between individuals.
Some patients have a few patches that remain stable for years, while others develop new patches or experience periods of more rapid spreading.
The condition may also become stable for a period before becoming active again.
Early assessment is useful, particularly when new patches are appearing, as treatment may help stabilise active disease and improve the opportunity for repigmentation.
What Are the Treatment Options for Vitiligo?
Vitiligo treatment generally has two main goals:
Control disease activity to reduce the development of new white patches.
Encourage repigmentation to restore some or most of the natural skin colour.
The most suitable treatment depends on the location, extent, duration and activity of vitiligo.
1. Topical Corticosteroids
Topical corticosteroids may be prescribed for localised vitiligo, particularly on the body and limbs.
They help reduce the immune activity responsible for damaging pigment-producing cells.
However, prolonged or inappropriate use may cause skin thinning and other side effects. Treatment should therefore follow a dermatologist's instructions.
2. Topical Tacrolimus
Tacrolimus ointment is commonly used for vitiligo affecting the face, eyelids and other sensitive areas.
Unlike topical corticosteroids, tacrolimus does not cause skin thinning.
It works by regulating local immune activity and may gradually encourage pigmentation to return.
Treatment generally needs to be continued for several months before the response can be properly assessed.
3. Topical Ruxolitinib Cream
Ruxolitinib is a newer topical treatment belonging to a group of medications called Janus kinase (JAK) inhibitors.
It targets inflammatory pathways involved in the autoimmune process of vitiligo.
Ruxolitinib cream has been approved in certain countries for eligible patients aged 12 years and above with non-segmental vitiligo.
It may improve repigmentation, particularly on the face, although several months of consistent treatment are usually required.
Availability, suitability and regulatory approval vary between countries.
4. Narrowband UVB Phototherapy
Narrowband ultraviolet B (NB-UVB) phototherapy is an established treatment for vitiligo, particularly when larger areas of the body are affected.
It uses carefully controlled ultraviolet light to help regulate immune activity and stimulate repigmentation.
Treatment commonly requires two to three sessions per week over several months, and some patients may need six to twelve months of treatment.
Phototherapy may be used alone or combined with selected topical medications.
5. Oral Medication for Rapidly Spreading Vitiligo
For patients whose vitiligo is spreading rapidly, a dermatologist may consider a short course of systemic treatment, such as carefully supervised oral corticosteroids.
The main purpose is to stabilise the condition and reduce further pigment loss, rather than directly restore skin colour.
These medications are not routinely required for stable vitiligo and must be used cautiously because of potential side effects.
6. Surgical Treatment
For selected patients with localised, stable vitiligo that has not responded adequately to other treatments, surgical procedures may be considered.
These include skin grafting and melanocyte transplantation.
Such treatments are generally reserved for carefully selected cases in which the disease has remained stable for a sufficient period.
How Long Does It Take for Skin Colour to Return?
Vitiligo treatment requires patience. Repigmentation is usually gradual, and visible improvement may not occur during the first few weeks.
The following provides a general guide to what patients may expect.
Treatment duration | Possible improvement |
First 1–2 months | Often little visible change |
3–6 months | Early pigmentation may begin returning in responsive areas |
6–12 months | More noticeable improvement may develop with continued treatment |
Beyond 12 months | Further repigmentation may occur, depending on treatment response |
These are approximate time frames, not guaranteed outcomes.
Some patients notice small brown spots appearing within the white patches. These spots may gradually enlarge and merge as pigmentation returns.
The location of vitiligo also influences treatment response.
The face and neck generally respond better, while the fingers, hands, feet and areas with white hair are often more difficult to repigment.
Even with appropriate treatment, complete restoration of natural skin colour may not be possible in every case.
Can Vitiligo Be Completely Cured ?
There is currently no treatment that guarantees a permanent cure for vitiligo.
However, available treatments can help many patients achieve meaningful repigmentation and reduce disease progression.
Some patients regain substantial skin pigmentation, while others experience partial improvement.
Importantly, not every patient needs active treatment. If the condition is stable and does not cause significant concern, choosing not to pursue repigmentation treatment is also reasonable.
Treatment decisions should consider the patient's preferences, disease activity and expected benefits.
Can Vitiligo Return After Successful Treatment?
Yes. Vitiligo may recur even after successful repigmentation.
This is because treatment can restore pigmentation without permanently eliminating the underlying autoimmune tendency.
New white patches may develop, or previously treated areas may gradually lose pigmentation again.
For selected patients, maintenance treatment, such as intermittent topical tacrolimus, may help reduce the risk of recurrence.
Regular follow-up allows treatment to be adjusted if new patches appear or the disease becomes active again.
How Can Patients Manage Vitiligo Better ?
Alongside medical treatment, several practical measures can help protect the skin and support overall well-being.
Protect the skin from sunburn. Use broad-spectrum sunscreen, preferably SPF 50+, particularly on exposed white patches that lack protective melanin.
Avoid unnecessary skin injury. Repeated scratching, rubbing or trauma may trigger new patches in susceptible individuals.
Follow the prescribed treatment plan. Repigmentation takes time, and consistency is important.
Consider cosmetic camouflage. Camouflage products may help make white patches less noticeable for patients who prefer this option.
Monitor for new patches. Photographs taken over time may help track disease progression and treatment response.
Look after emotional well-being. Vitiligo can affect confidence and quality of life, and support is available when needed.
There is currently no convincing evidence that a particular diet or supplement can reliably cure vitiligo. Patients should be cautious about products promising rapid or permanent restoration of skin colour.
When Should You See a Dermatologist?
Consider dermatological assessment if:
New white patches appear on the skin.
Existing patches are spreading rapidly.
White patches develop on the face or other visible areas.
You are uncertain whether the patches are caused by vitiligo.
You would like to discuss treatment options and expected outcomes.
The condition is affecting your confidence or emotional well-being.
Not all white patches are caused by vitiligo. Conditions such as pityriasis alba, certain fungal infections and post-inflammatory hypopigmentation may look similar.
A dermatologist can assess the skin and may use a Wood's lamp examination to help confirm the diagnosis.
Assessment for associated autoimmune conditions, particularly thyroid disease, may also be appropriate in selected patients.
Living With Vitiligo
Vitiligo is a long-term skin condition, but its course varies considerably between individuals.
Some people develop only a few stable patches, while others may experience spreading or recurrence.
Although a permanent cure cannot be guaranteed, treatments such as topical corticosteroids, tacrolimus, ruxolitinib cream and phototherapy offer opportunities to stabilise the condition and restore pigmentation.
Early assessment, appropriate treatment and realistic expectations are important for achieving meaningful improvement.
Most importantly, vitiligo is not contagious, and patients should not feel pressured to undergo treatment solely because their skin looks different.
For those who wish to pursue treatment, an individualised approach can help identify the most suitable options based on their condition and personal preferences.
