The location of smaller macules shifts and changes over time, as certain areas of skin lose and regain their pigment. If vitiligo affects the way you feel about yourself, you’re not alone. In talking with their patients, dermatologists have learned that vitiligo often changes how people feel about themselves. Skin that’s lost pigment is more sensitive to sunlight, so it sunburns quickly. When vitiligo affects hair color, dye can be used to camouflage these patches, but proceed with caution because, in some cases, hair dye can make vitiligo worse. Currently, no credible evidence supports the use of collagen for hair growth in humans.
Types of Vitiligo
If you see light-colored spots or patches on your skin, see a board-certified dermatologist. A dermatologist can tell you whether you have vitiligo or another medical condition. There are many other skin diseases that can cause skin lightening, which can be treated. What you see when vitiligo begins is also affected by the type of vitiligo you have. The most common type, non-segmental vitiligo, tends to spread slowly with new patches developing off and on throughout a person’s life.
Medical History and Physical Examination
He showed that a medicine originally intended for rheumatoid arthritis can restore normal skin pigment for patients with vitiligo. In vitiligo, the drug can work to calm the immune system so that it does not attack melanocytes. In 2022, the FDA approved a topical JAK inhibitor (ruxolitinib cream) for the treatment of vitiligo in both adult and pediatric patients (down to age 12 years). This represents the first FDA-approved treatment for vitiligo, and is part of the complement of vitiligo therapies offered by Yale Medicine dermatologists. Medications and light-based therapies are available to help restore skin color or even out skin tone, though results vary and are unpredictable.
Segmental Vitiligo
No drug can stop the process of vitiligo — the loss of pigment cells (melanocytes). But some drugs, used alone, in combination or with light therapy, can help restore some color. The amount of affected skin varies for each person diagnosed with vitiligo. Some people experience a few depigmented areas, while others have a widespread loss of skin color. Once vitiligo is no longer active, the patches turn completely white, as shown here.

There is no cure for vitiligo and treatment is often unsatisfactory. The aim is to stop progression of the disease (stabilisation), and to achieve satisfactory re-pigmentation. Genetic factors appear to contribute to 80% of vitiligo risk, whilst environmental factors account for 20%.
Treatment is usually given twice weekly for a trial period of 3–4 months. If re-pigmentation is observed, treatment is continued until re-pigmentation is complete or for a maximum of 1–2 years.

Oral collagen supplements may be sold as pills, powders, or certain foods.
They may be in the form of collagen peptides or hydrolyzed collagen, which are forms of collagen that are broken down and more easily absorbed. Collagen supplements contain amino acids (the building blocks of protein). They may also contain additional nutrients such as vitamin C, zinc, or biotin. If the patches are relatively small, skin camouflage cream can be used to cover them up. If available, the GP may use an ultraviolet (UV) lamp called a Wood's lamp to look at your skin in more detail.

This is where healthy hair follicles are removed from areas unaffected by vitiligo and placed in areas of pigment loss. Smith initially observed that there were white patches near the mouth and chin of Buster. This was before the white color eventually spread across the dog's body and face.
Types
Melanin is produced by skin cells called melanocytes, and it gives your skin its colour. There's no way of predicting how much skin will be affected. Vitiligo affects everyone differently, so the growth rate of skin patches depends on who you are and your medical condition. Treatments for vitiligo aim to restore color balance to your skin.
It's not uncommon to have a rapid loss of color in patches, and then the disease goes dormant for a period of time. While treatments cannot cure vitiligo, some may help slow its progression. This includes certain types of topical or oral medications and phototherapy. The primary physical effect is that the loss of pigment increases your risk of sunburn. You can protect your skin by applying sunscreen with a sun protection factor (SPF) of 30 or higher and wearing sun-protective clothing. Vitiligo doesn’t appear to be inherited, and many people with vitiligo don’t have a family history of the disorder.
Vitiligo fluoresces (glows) when the purple Wood's lamp is shined onto the skin. This form of vitiligo, which is much less common than non-segmental vitiligo, affects only one segment of skin and tends to stop growing once the initial patch is established. The main goals for treating vitiligo are regaining pigment in affected areas and minimizing the contrast between normal and affected skin, through sunscreen and sun avoidance. Soto was diagnosed with vitiligo at age 12 after she saw a white spot on her neck and then noticed another one appear within a few months. A big concern when it comes to vitiligo complications is the emotional toll of living with a very visible skin condition, especially one that can begin early in life.
More than 90% of the adult vitiligo cases are of the generalized vulgaris or acrofacial types, while in children, segmental vitiligo constitutes 15–30% of the cases. It is currently widely accepted that vitiligo is the result of autoimmune destruction of melanocytes. One woman confided that she wanted to wear a short-sleeved dress to a wedding but didn’t.
To maintain results, dermatologists often prescribe a medication that you apply to your skin a few times per week. Light therapy is most effective at restoring color to the face and neck. Like other treatments for vitiligo, the lips, tips of the fingers, and toes are least responsive to treatment with light therapy. You could also have another condition like tinea versicolor. A board-certified dermatologist can give you an accurate diagnosis. The most common presentation is the complete loss of pigment in single or multiple macules or patches of skin, with characteristic chalk- or milky-white colour.
While vitiligo itself is not painful, the affected skin may be itchy, painful, or sensitive to sunlight. This occurs because the skin in the affected areas is more vulnerable to damage from the sun’s UV rays. People with vitiligo should take extra precautions when exposed to sunlight, such as wearing protective clothing and using sunscreen. Segmental vitiligo, on the other hand, affects only one side of the body and is usually seen in younger individuals. Segmental vitiligo is also less common than non-segmental vitiligo, accounting for only 10% of cases.
