Melasma Clinical Trial
Official title:
Stem Cell Derived Exosomes in the Treatment of Melasma and Its Percutaneous Penetration
Melasma is a refractory skin disease due to its complex pathogenesis and difficult treatment. Studies have found that human umbilical cord mesenchymal stem cell-derived exosomes (hUCMSC-Exos) could serve as a novel cell-free therapeutic strategy in regenerative and aesthetic medicine. It could potentially treat melasma, but the skin barrier is a challenge. This study aims to explore the safety and efficacy of hUCMSC-Exos in the treatment of melasma and means to promote its percutaneous penetration.
80 patients with melasma treated in our department were divided into four groups. 1565 nm nonablative fractional laser (NAFL) combined with normal saline treatment group was used for Group A. Microneedle，NAFL，a plasma named Peninsula Blue Aurora Shumin Master (PBASM) combined with hUCMSC-Exos were used for the other treatment groups (B, C, and D, respectively). The treatment was given four times with an interval of one month. The degree of pain post-treatment, MASI, improvement rate, physician global assessment score, satisfaction and complications after treatment were evaluated six months later. ;
