Can your own fat cells help restore skin color in vitiligo?
NCT ID NCT07763262
First seen Aug 13, 2026 · Last updated Aug 14, 2026 · Updated 1 time
Summary
This trial tests whether injecting a specially processed form of a patient's own fat tissue, called nanofat, can improve repigmentation in stable vitiligo when combined with standard narrowband UVB light therapy. In each of 20 adults, one vitiligo patch receives nanofat plus light therapy, while a similar patch gets light therapy alone, allowing a direct comparison. Researchers will measure the percentage and speed of repigmentation, patient satisfaction, and any side effects to see if nanofat adds real benefit.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Autologous nanofat injection (prepared from the participant's own fat tissue) plus NB-UVB phototherapy
- What this could lead to
- If effective, this approach could offer a new, natural way to improve repigmentation in stable vitiligo, potentially reducing the need for more invasive treatments.
- What could go wrong
- This is a small, early-stage trial with only 20 participants, so results may not apply broadly. The procedure involves harvesting fat, which carries risks like infection or discomfort, and the benefit over light therapy alone is unproven.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Adults aged 18 years or older. * Male or female patients. * Patients with clinically diagnosed stable vitiligo. * Presence of comparable vitiligo sites suitable for the split-site study design. * Ability to undergo autologous nanofat harvesting and injection. * Ability and willingness to undergo NB-UVB phototherapy three times weekly for 3 months. * Ability to comply with study follow-up and assessment procedures. * Provision of written informed consent. Exclusion Criteria: * Active or progressive vitiligo. * Active infection or inflammation at the treatment sites. * Significant uncontrolled systemic disease that could interfere with treatment or assessment. * Contraindication to NB-UVB phototherapy. * Contraindication to the nanofat harvesting or injection procedure. * Pregnancy or breastfeeding, if this was an exclusion criterion in your protocol. * Previous treatment of the selected study sites that could interfere with assessment. * Inability to comply with the study protocol or follow-up. * Any condition considered by the investigator to interfere with the safety or assessment of the study.
