Getting pigment back in your skin is possible, but the approach depends entirely on why you lost it. Vitiligo, fungal infections, eczema flare-ups, and skin injuries can all leave behind pale or white patches, and each one responds to different treatments. The timeline is slow regardless of the cause: visible improvement typically takes at least six months, and full repigmentation can take a year or longer.
Why Your Skin Lost Its Color
Your skin gets its color from melanocytes, the cells that produce the pigment melanin. When those cells are destroyed, suppressed, or blocked from doing their job, the skin in that area turns lighter or completely white. Figuring out the underlying cause is the first step, because it determines which treatments will actually work.
The most common reasons for pigment loss include:
- Vitiligo: An autoimmune condition where the immune system attacks and destroys melanocytes, leaving sharply defined white patches. It affects about 1% of the population worldwide.
- Post-inflammatory hypopigmentation: Light patches left behind after eczema, psoriasis, burns, cuts, or other skin injuries. The melanocytes are still there but temporarily stunned.
- Tinea versicolor (pityriasis versicolor): A fungal overgrowth caused by Malassezia yeast that produces metabolites interfering with pigment production. It typically shows up as scaly, lighter patches in oily areas like the chest, back, and shoulders.
A dermatologist can usually distinguish between these with a visual exam and a Wood’s lamp, which highlights pigment differences under ultraviolet light. Getting the right diagnosis matters because treating vitiligo like a fungal infection, or vice versa, wastes months of effort.
Topical Treatments That Stimulate Pigment
For vitiligo, two categories of prescription creams are the standard first-line treatment: corticosteroids and calcineurin inhibitors. Both work by calming the immune attack on melanocytes, but calcineurin inhibitors do something extra. They actively stimulate melanocyte growth, migration, and pigment production. Specifically, they boost the enzyme responsible for melanin synthesis and encourage nearby stem cells to produce new pigment-making cells. This dual action, reducing inflammation while promoting new pigment, is why they’re particularly useful on the face and neck, where skin tends to respond best.
Topical corticosteroids are typically used on the body rather than the face, since long-term steroid use on facial skin can cause thinning. Treatment courses usually run in cycles of a few months with breaks in between.
A newer option is a topical JAK inhibitor cream, which became the first FDA-approved treatment specifically for vitiligo repigmentation. In two large phase 3 trials published in the New England Journal of Medicine, about 30% of patients using the cream achieved at least 75% improvement in facial pigment at 24 weeks, compared to roughly 7 to 11% using a placebo cream. Results continued improving beyond that point, with more patients responding by week 52. It works by blocking specific immune signals that drive melanocyte destruction.
Light Therapy for Repigmentation
Ultraviolet light is one of the most effective tools for bringing pigment back, and it works across multiple conditions. For vitiligo, narrowband UVB phototherapy is the gold standard. Sessions are given two to three times per week for a minimum of three months, though many people continue for six to twelve months or longer. The UV exposure stimulates dormant melanocytes in hair follicles and at the edges of white patches to start producing pigment again.
An excimer laser delivers a concentrated beam of the same wavelength directly to affected patches, sparing surrounding skin. A retrospective study comparing targeted narrowband UVB, excimer laser, and excimer lamp found all three produced comparable repigmentation results, with no statistically significant difference in effectiveness. The choice often comes down to the size and location of your patches. Lasers work well for small, isolated spots. Broader phototherapy is more practical when pigment loss covers larger areas.
For tinea versicolor, UV exposure plays a different role. After antifungal treatment clears the yeast, the pale patches can persist for weeks or months because the melanocytes need time to resume normal pigment output. Controlled sun exposure or UV therapy can help speed up this process by encouraging existing pigment-containing structures inside the cells to mature. That said, deeply depigmented patches from long-standing fungal infections can be stubborn and slow to improve even with UV therapy.
When Pigment Returns on Its Own
Post-inflammatory hypopigmentation, the kind you get after eczema, burns, or skin procedures, usually resolves without medical intervention. The melanocytes in those areas aren’t destroyed, just temporarily disrupted. As the skin heals and turns over, pigment production gradually resumes. This can take anywhere from a few weeks to several months depending on how deep the original injury was and your skin tone. People with darker skin tend to notice the contrast more and may feel it takes longer, though the underlying healing timeline is similar.
The most important thing you can do during recovery is protect the affected area from sun exposure. This sounds counterintuitive when you’re trying to get color back, but the goal is to prevent the surrounding normal skin from tanning darker, which only makes the pale patches more obvious. Sunscreen on the lighter areas and surrounding skin keeps the contrast from widening while your melanocytes catch up.
If post-inflammatory patches haven’t improved after several months, a dermatologist may recommend a short course of a calcineurin inhibitor cream or targeted phototherapy to nudge the melanocytes back into action.
Treating Fungal-Related Pigment Loss
With tinea versicolor, the first priority is eliminating the yeast overgrowth. Antifungal creams, shampoos, or oral antifungal medication clear the active infection, but the white patches don’t disappear immediately. The fungus produces tryptophan-derived metabolites that interfere with melanin production, and its scaly layer may also physically block UV light from reaching melanocytes. Once the fungus is gone, your skin needs time and some UV exposure to restart pigment production.
Expect the pale patches to linger for weeks to months after successful antifungal treatment. Moderate sun exposure can help, but there’s limited high-quality evidence on the best approach for speeding this up. If you’re prone to recurrence, maintenance antifungal treatment during warm, humid months can prevent new patches from forming.
Surgical Options for Stable Vitiligo
When vitiligo has been stable (no new patches and no expansion of existing ones) for at least a year and hasn’t responded to other treatments, surgical approaches become an option. These procedures involve transplanting healthy melanocytes from your own normally pigmented skin to the white patches.
A large meta-analysis found that after a single surgical session, about 53% of patients achieved greater than 90% repigmentation, and 81% achieved at least 50% repigmentation. Results were best in younger patients, those with segmental vitiligo (patches on one side of the body), and patches located on non-acral areas, meaning areas other than the hands, feet, and bony prominences. Fingertips and toes are the hardest to repigment with any method.
The procedure is typically done under local anesthesia. A thin layer of skin is harvested from a donor site, usually the thigh, and processed into a suspension of melanocytes and skin cells that gets applied to the prepared recipient area. Recovery involves keeping the treated area protected for one to two weeks while the transplanted cells establish themselves.
Nutritional Support for Repigmentation
Certain nutritional deficiencies appear linked to pigment loss, and supplementation may provide a modest boost alongside other treatments. In a two-year study of 100 vitiligo patients, those who took vitamin B12 and folic acid while getting regular sun exposure saw clear repigmentation in 52% of cases. The improvement was most pronounced in sun-exposed areas, suggesting the vitamins work best as a complement to UV exposure rather than as a standalone treatment.
Ginkgo biloba has also shown modest effects. In a pilot clinical trial, participants taking 60 mg twice daily for 12 weeks experienced an average 15% repigmentation of their vitiligo patches and, notably, a significant reduction in disease spread. The effect size is small, but the ability to slow progression while promoting some repigmentation makes it an interesting add-on for people who want to try a supplement alongside their primary treatment.
Neither supplement replaces medical treatment, and neither works quickly. But for people already doing phototherapy or using topical medications, adding B12, folic acid, or ginkgo biloba is low-risk and may contribute to better outcomes over time.
Realistic Timelines and Expectations
Repigmentation is a slow process regardless of which treatment you use. Changes in skin color can only be reliably detected over a timeframe of about six months, so judging a treatment’s effectiveness before that point is premature. Many dermatologists recommend committing to at least six to twelve months of consistent treatment before deciding whether it’s working.
When pigment does return, it typically appears first as small brown dots around hair follicles within the white patches, then gradually fills in from the edges. Facial skin repigments faster and more completely than hands, feet, and joints. Areas with white hair (where follicular melanocyte reserves are depleted) are the most resistant to treatment.
Complete repigmentation isn’t always achievable, especially for widespread vitiligo. But meaningful cosmetic improvement, enough that patches blend with surrounding skin, is a realistic goal for most people with consistent treatment. Combining approaches, such as a topical medication with phototherapy, tends to produce better results than any single treatment alone.
