In short. Corticosteroids, calcineurin inhibitors, and newer topical agents: what each class does, and the monitoring each one requires.
Key points
- Steroids thin the skin, and calcineurin inhibitors sting and carry a small long-term question mark.
- Neither is a reason to avoid treatment, but both are reasons to have the treated skin reviewed at intervals rather than left on a repeat prescription for years.
Topical treatment is usually where vitiligo care begins, particularly when the involved area is limited. The aim is to interrupt the immune attack on melanocytes and, if the disease is stable enough, to encourage pigment cells to return. Several classes of topical agent are used, and each has a different balance of benefit and risk.
Topical corticosteroids
Corticosteroids applied to the skin reduce the local immune activity that is destroying melanocytes. They are effective on the face and neck, widely used, and the most accessible option in most settings. The difficulty is that potency and duration matter. Prolonged use of a potent steroid on thin skin causes skin thinning, visible blood vessels, stretch marks and outbreaks of small spots around the hair follicles, and the face and skin folds are the most vulnerable. For that reason they are generally used in a defined course, often with a break, and on the face a milder preparation is preferred. Monitoring means a clinician looking at the treated skin at intervals for early signs of steroid damage, not simply repeating the prescription indefinitely.
Calcineurin inhibitors
Calcineurin inhibitors are non-steroidal topical agents that also calm local immune activity. Their advantage is that they do not thin the skin, which makes them particularly useful on the face, the eyelids and the neck, and for children. Their drawbacks are a burning or stinging sensation on first application, which usually settles, and a recognised association with skin infections and, very rarely, with certain skin cancers. That is a reason for not applying them to skin that is already damaged or infected, and for continued surveillance. They are often used in rotation with a steroid rather than continuously.
Newer topical agents
Newer topical preparations target specific steps in the immune pathway involved in vitiligo, and some have shown encouraging repigmentation on the face in clinical studies. They are used in some centres, sometimes alongside phototherapy, and their longer-term role is still being defined. Availability, cost and licensing vary, and they are not a simple substitute for established treatment.
Practical points that apply to all of them
Topical treatment works slowly. Some pigment may begin to appear after a few months, and a fair judgement usually requires several. It must be applied to the right areas and continued in order to hold the result. It works best on the face and neck and least well on the hands, feet and lips. For extensive disease it is usually combined with phototherapy rather than used alone, and it should never be applied to broken or infected skin.
Every topical has a monitoring plan

Contact your clinician if
- The treated skin becomes thin, shiny or bruised, or develops visible blood vessels or stretch marks.
- You develop a burning sensation that does not settle, or a new rash or infection in the treated area.
- There is no repigmentation and no stabilisation after several months of correct use.
Frequently asked questions
Why are topical corticosteroids used in defined courses rather than continuously?
Prolonged use of a potent steroid on thin skin causes skin thinning, visible blood vessels, stretch marks and outbreaks of small spots around the hair follicles. The face and the skin folds are the most vulnerable. They are therefore generally used in a defined course, often with a break, and a milder preparation is preferred on the face.
Why might a calcineurin inhibitor be chosen for the face or for a child?
Calcineurin inhibitors are non-steroidal topical agents that do not thin the skin, which makes them particularly useful on the face, the eyelids and the neck, and for children. They can cause burning or stinging on first application, which usually settles, and they are often used in rotation with a steroid.
How long does topical treatment take to show an effect, and where does it work best?
Topical treatment works slowly. Some pigment may begin to appear after a few months, and a fair judgement usually requires several. It works best on the face and neck and least well on the hands, feet and lips, and it must be continued in order to hold the result.
Risks & Limitations
- Repigmentation is slow, measured in months to years, and is often partial rather than complete.
- Vitiligo is unpredictable: treatment can control it, but nothing guarantees that it will stop spreading.
- Treatment usually needs to continue to hold the result, and relapse is common after it is stopped.
- Prolonged topical steroid use can thin the skin, cause visible blood vessels and stretch marks, and trigger outbreaks of small spots around the hair follicles.
- Phototherapy can burn, and the ultraviolet dose accumulates over a lifetime, raising the risk of skin ageing and skin cancer.
- The face and neck respond best; the hands, feet and lips are the hardest areas, where pigment may never return.
- No treatment works for everyone, and the response of an individual patch cannot be predicted with certainty.
When to Seek Care
- Depigmentation is spreading rapidly, or new patches are appearing over weeks rather than months.
- Depigmentation involves the eyelids or the skin around the eyes.
- New symptoms suggest a thyroid or other autoimmune condition — persistent fatigue, weight change, feeling cold, a neck swelling, or excessive thirst.
- Blistering, burning or severe pain after a phototherapy session — stop treatment and seek advice.
- Eye pain, redness, light sensitivity or blurred vision, which need prompt assessment.
