Quick answer. Vitiligo is a condition where the immune system destroys pigment cells (melanocytes), causing well-defined white patches on the skin. It is not contagious and not caused by poor hygiene or diet. While not physically harmful, it is very visible on Asian skin and can have a real psychological impact. Treatments aim to restore pigment and stabilise the condition: topical steroids and calcineurin inhibitors, narrowband UVB (NB-UVB) phototherapy, and newer options such as ruxolitinib cream, which the National Skin Centre was first in Singapore to offer for non-segmental vitiligo. Repigmentation is gradual and varies; the face responds best, hands and feet least. Realistic expectations and emotional support matter.

Vitiligo causes patches of skin to lose their colour, turning milky-white. It happens when the body’s own immune system attacks the melanocytes — the cells that make pigment. It is an autoimmune condition, not an infection, and it cannot be “caught” from or passed to another person.
On Singapore’s predominantly medium-to-darker skin tones the contrast can be striking, which is one reason vitiligo often affects confidence and mood. The good news is that several treatments can help restore pigment, and new options have recently become available. This guide explains the causes, treatment choices, and what results you can realistically expect.
At a glance
| Treatment | How it works | Notes |
|---|---|---|
| Topical corticosteroids | Calm the immune attack on pigment cells | First-line for small/limited areas; used short-term to limit skin thinning |
| Topical calcineurin inhibitors (tacrolimus, pimecrolimus) | Reduce immune activity without skin thinning | Useful on face and skin folds; suited to longer-term use |
| Narrowband UVB (NB-UVB) phototherapy | Light stimulates repigmentation | Mainstay for widespread vitiligo; needs repeated clinic sessions over months |
| Ruxolitinib cream (JAK inhibitor) | Blocks immune signals driving pigment loss | Newer option; NSC was first in Singapore to offer it for non-segmental vitiligo |
| Surgical / cell transplant techniques | Move pigment cells into stable bald patches | For selected stable, segmental cases at specialist centres |
| Camouflage & sun protection | Conceal patches; protect depigmented skin | Supportive; cosmetic camouflage and sunscreen help appearance and safety |
What causes vitiligo?
Vitiligo is considered an autoimmune condition: the immune system mistakenly targets and destroys melanocytes, the cells that give skin its colour. The exact trigger is not fully understood, but genetic factors play a role, and it is sometimes associated with other autoimmune conditions such as thyroid disease.
Key points patients often want reassurance on:
- It is not contagious — you cannot pass it to family or others.
- It is not caused by poor hygiene, diet or applying the “wrong” products.
- The depigmented skin is otherwise healthy, but it lacks natural sun protection, so those areas burn easily.
The psychological impact
Because vitiligo is highly visible — especially on darker skin and on the face, hands and lips — it can affect self-esteem, social confidence and mood. Studies consistently show many people with vitiligo experience anxiety, embarrassment or low mood, and in some cultures the condition is misunderstood or stigmatised.
This emotional burden is real and valid even though vitiligo is medically harmless. Speaking to your dermatologist about how it affects you, connecting with patient support communities, and seeking counselling where needed are all legitimate parts of care, not signs of vanity.
Topical treatments
For limited or early vitiligo, creams and ointments are usually tried first:
- Topical corticosteroids suppress the local immune attack and can encourage repigmentation. They are effective but are used in a controlled way because prolonged use can thin the skin.
- Topical calcineurin inhibitors (tacrolimus, pimecrolimus) are steroid-free and especially useful on the face and skin folds, where they can be used for longer.
- Ruxolitinib cream is a newer topical JAK inhibitor that blocks immune signalling driving pigment loss. The National Skin Centre was the first healthcare institution in Singapore to offer it for non-segmental vitiligo, and it may be combined with phototherapy.
Phototherapy and newer options
Narrowband UVB (NB-UVB) phototherapy is a mainstay for more widespread vitiligo. Controlled doses of a specific UVB wavelength delivered in a clinic cabinet (or with targeted devices for small areas) stimulate surviving melanocytes to repigment the skin. It requires repeated sessions, typically two to three times a week over several months, and is closely supervised.
Combining NB-UVB with topical treatment such as ruxolitinib cream may accelerate and strengthen repigmentation in some people. For selected stable or segmental vitiligo that has not responded to medical treatment, surgical melanocyte transplant techniques may be considered at specialist centres. Your dermatologist will tailor the plan to the type, extent and stability of your vitiligo.
Realistic expectations and outcomes
It is important to set honest expectations:
- Repigmentation is gradual, often taking many months, and results vary greatly between individuals.
- The face and neck tend to respond best; the hands, feet and lips respond least.
- Treatment can stabilise the condition and restore colour for many, but a complete, permanent cure cannot be guaranteed, and patches can sometimes recur or spread.
- Ongoing or maintenance treatment may be needed to keep results.
Many people also choose cosmetic camouflage and diligent sun protection for the white patches. Note that treatments pursued purely for cosmetic appearance are generally not claimable under MediSave; discuss costs, which vary, with your clinic.
How to prepare for your dermatology appointment
A little preparation helps your dermatologist plan the right treatment more quickly. Before your visit, it is useful to note when you first saw the patches, whether they are spreading, staying stable or improving, and whether any new patches have appeared in areas of friction or recent injury. Bring a list of creams, supplements and other medications you are using, and mention any personal or family history of autoimmune conditions such as thyroid disease, diabetes or alopecia. If you have tried treatments before, note what helped and what did not.
- Photograph your patches in good natural light every few weeks so changes are easier to track.
- Avoid sunburn before the visit, as fresh tanning around the patches can make assessment harder.
- Write down how the condition affects your mood, work or social life, so this can be addressed too.
Self-management at home
While medical treatment does the heavy lifting, daily habits support your results and protect depigmented skin. Apply a broad-spectrum sunscreen to exposed white patches, as these areas lack the natural pigment that shields against ultraviolet light and can burn easily. Sensible sun protection also reduces the contrast between affected and unaffected skin. Cosmetic camouflage products and self-tanning lotions can even out appearance for special occasions, and your clinic or pharmacist can suggest suitable brands. Be consistent with prescribed creams and phototherapy sessions, as repigmentation is slow and rewards patience.
Common questions
Will my vitiligo definitely spread?
Not necessarily. Some people have stable patches for years, while others see gradual spread. Treatment can help stabilise the condition, so it is worth seeing a dermatologist rather than waiting.
Can children be treated for vitiligo?
Yes. Many treatments, including certain topical options and phototherapy, can be used in children under specialist supervision, with doses and approaches tailored to age.
Is vitiligo linked to other health problems?
It is sometimes associated with other autoimmune conditions, particularly thyroid disease. Your doctor may suggest simple blood tests to check for these.
