What is Vitiligo?
We see people with white patches on the skin in small children and elderly, men and women, its seen in all age groups, and all walks of life. What is this condition? Is it something to worry about? Or is it to be ignored? Let's dive into the topic that needs to be cleared for you today, especially if you or someone you know has this condition.
Vitiligo is a skin condition that results in the loss of pigmentation, causing white patches to appear on the skin. These patches can occur anywhere on the body, including the face, hands, and feet. The exact cause of vitiligo is unknown, but it is believed to be an autoimmune disorder where the body's immune system mistakenly attacks and destroys melanocytes (skin colour giving cells, without these, our skin would be transparent🤩🤩 , the cells responsible for producing melanin – the pigment that gives skin its color.  Â
Who can get Vitiligo?
Vitiligo can affect people of all ages, races, and ethnicities. However, it often begins to appear before the age of 20. In some cases, vitiligo can be triggered by stressful events, sunburn, or exposure to certain chemicals. A family history of vitiligo also increases the risk of developing the condition.
Lifestyle Factors causing Vitiligo:
Stress: Chronic stress has been linked to the onset and progression of vitiligo. It's believed to impact the immune system.  Â
Sun Exposure:Â While sun exposure is generally beneficial for skin health, excessive or unprotected sun exposure can potentially trigger or worsen vitiligo in susceptible individuals.
Skin Trauma: Injuries, burns, or cuts to the skin can sometimes lead to the development of vitiligo at the site of the injury.  Â
Diet:Â While there's no concrete evidence that specific dietary factors cause vitiligo, maintaining a balanced diet rich in antioxidants is generally beneficial for overall health and might support skin health.
Internal Causes for Vitiligo:
Autoimmune Diseases: Vitiligo is often associated with other autoimmune conditions such as thyroid disease like autoimmune thyroiditis, type 1 diabetes, and pernicious anemia, etc.  Â
Genetic Predisposition:Â Having a family history of vitiligo increases the risk of developing the condition, but not necessarily in all of them.
Neurotransmitters:Â Some research suggests that neurotransmitters, chemicals that transmit messages between nerve cells, might play a role in vitiligo.
Oxidative Stress:Â An imbalance between free radicals and antioxidants in the body can contribute to cell damage, including melanocytes. So, our lifestyle involves high calorie diet, smoking, alcohol, work stress, any of these can affect the health of our cells and trigger these.
Types of Vitiligo
There are several types of vitiligo, including:
Localized vitiligo:Â This is the most common type, characterized by white patches in one or a few specific areas of the body.
Generalized vitiligo:Â This involves the spread of white patches to multiple areas of the body.
Segmental vitiligo:Â This type affects only one side of the body.
Universal vitiligo:Â This is a rare form where almost all of the skin loses its pigment.
Lip Tip Vitiligo
Lip tip vitiligo is a specific type of vitiligo that affects the tip of the lips, tip of the fingers and toes. It can be particularly noticeable and may have a significant impact on a person's self-esteem. This condition can often be successfully treated with excimer laser therapy.
Vitiligo in Children
Vitiligo does affect children. Early diagnosis and treatment can help to prevent emotional distress and promote a positive body image. It is important that treatment is started early and is maintained, with regular follow ups and not letting problem progression to a large level and then approaching treatment. Children need the maximum care and management, coz it can be long term in some of them.
Prognosis of Vitiligo
Vitiligo is a chronic condition, it has its own pattern of occuring in individuals. However, with appropriate treatment, it is possible to manage the appearance of white patches and improve quality of life. The progression of vitiligo varies from person to person. In some cases, the condition may stabilize and stop spreading, while in others, the white patches may continue to grow.
Diagnosis of Vitiligo
A dermatologist can diagnose vitiligo based on a physical examination of the skin. In some cases, additional tests may be recommended to rule out other conditions. These tests may include:
Blood tests:Â To check for underlying medical conditions that can be associated with vitiligo, such as thyroid disease or vitamin B12 deficiency, also for other autoimmune conditions and pre treatment clearance checks.
Skin biopsy:Â A small sample of skin is removed for examination under a microscope to confirm the diagnosis.
Treatment Options for Vitiligo
While there is no cure for vitiligo, several treatment options can help to improve the appearance of the skin. These include:
Topical immune regulators:Â These creams or ointments can help to reduce inflammation and promote repigmentation. These need to be classified based on body area, skin type and then to be taken with a Dermatologist prescription only.
Light therapy:Â Exposure to ultraviolet (UV) light can help to stimulate melanin production, though which phase to give light therapy is decided by the treating medical Professional.
Excimer laser therapy:Â A targeted form of light therapy that is highly effective in treating vitiligo.
Depigmentation:Â In cases of widespread vitiligo, this process involves lightening the remaining pigmented skin to match the white patches ( this is rarely done nowadays, because most of them reach treatment centres early before it spreads too much).
Camouflage makeup:Â This can be used to cover up white patches.
Surgery:Â Skin grafting or melanocyte transplantation may be considered in some cases.
Light Therapy for Vitiligo
Light therapy involves exposing the affected skin to ultraviolet (UV) light. This can help to stimulate melanin production and reduce the appearance of white patches. There are different types of light therapy, including:
Narrowband UVB (NBUVB):Â This type of light therapy uses a specific wavelength of UV light that is effective in treating vitiligo.
Excimer laser therapy:Â This is a highly targeted form of light therapy that delivers 308nm light directly to the affected areas.
Excimer Laser Therapy: A Breakthrough Treatment for Vitiligo
Excimer laser therapy has emerged as a highly effective treatment for vitiligo. This advanced technology delivers a focused beam of ultraviolet light directly to the affected skin, stimulating repigmentation without damaging the surrounding healthy tissue.
How Does Excimer Laser Work?
The excimer laser emits a specific wavelength of 308 nm light that targets melanocytes, the pigment-producing cells in the skin. This stimulates the production of melanin, leading to a gradual return of skin color.
What to Expect After Excimer Laser Treatment
After each treatment session, the treated area may appear slightly red or swollen, but these side effects usually subside within a few hours. Most patients experience minimal discomfort during the procedure.
How Long Does it Take to See Results?
The number of treatment sessions required varies depending on the severity of vitiligo. Typically, patients may start to see visible results within a few weeks of treatment. Consistent treatment is essential to achieve optimal results.

Living with vitiligo can be challenging, but it is important to remember that you are not alone. With the advancements in treatment options, such as excimer laser therapy, there is hope for improving the appearance of vitiligo and enhancing self-esteem.
