Pigmentation Pipeline: Vitiligo and Melasma Treatment Advances

 has moved from an underserved disease to one of dermatology's most active treatment areas, according to George Martin, MD, who discussed disorders of pigmentation at 

 Martin, a dermatologist at the Dermatology and Laser Center of Maui and the co-founder of Scholars in Medicine and Maui Dermatology, structured his session around 2 categories: depigmentation disorders like vitiligo and hyperpigmentation disorders like melasma.

Vitiligo affects up to 1% of the population, and about half of cases begin before 20 years old.

, Martin noted the disease carries a genetic association and was long considered an orphan condition before targeted therapies arrived.

Topical Ruxolitinib Shows Durable, Growing Benefit

Topical ruxolitinib, a JAK1/2 inhibitor, remains the 

only FDA-approved topical therapy for vitiligo

 Martin said its effect does not plateau. Patients continue to show increasing repigmentation 2 and 3 years into treatment, a pattern he described as "the gift that keeps on giving."

The therapy's main limitation is body surface area. Martin said patients with more extensive involvement, generally above 50% body surface area, need systemic options layered on top of topical treatment.

Several oral JAK inhibitors are advancing through late-stage trials for vitiligo. Martin pointed to povorcitinib (a JAK1 inhibitor) and ritlecitinib (a JAK3/TEC inhibitor) as therapies positioned to expand systemic options.

 AbbVie announced topline phase 3 results of upadacitinib for vitiligo back in October 2025.

Martin said these therapies will likely replace the current standard approach for widespread, active vitiligo: pulse-dose dexamethasone given twice weekly, often combined with narrowband UVB phototherapy. He cited an algorithm developed by John Harris, MD, PhD, now chair at Massachusetts General Hospital, as a framework many clinicians already follow for turning off active disease before starting repigmentation therapy.

Not every practice has in-office narrow band UVB, Martin said, which pushes many clinicians toward topical and systemic regimens by default. He expects ruxolitinib to increasingly replace topical steroids in combination protocols, both for its efficacy and its safety profile.

Melasma Treatment Requires a Combined Approach

On the hyperpigmentation side, Martin focused on melasma, which he called one of the most common disorders clinicians see in daily practice. He said effective treatment requires combining skin-lightening topicals with procedures such as peels and lasers, rather than relying on a single modality.

Martin said that photoprotection remains equally important, but current sunscreens fall short. A recent consensus statement on visible light, led by Henry Lim, MD, established the need to block visible light in addition to UVA and UVB.

“Sadly, all of our current sunscreens are ineffective at blocking visible light and require some combination of iron oxides or some other visible blocking molecules,” Martin said. “There is some really good science out there to show that we're now capable of blocking visible light, but this combination of minerals has not yet been commercialized.”
