Stem Cell Derived Exosomes in the Treatment of Melasma and Its Percutaneous Penetration
Fujian Medical University Union Hospital

INTERVENTIONAL
Conditions
Summary
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.
Eligibility
Inclusion Criteria5
- \- Patients diagnosed with chloasma who meet the clinical diagnostic standards and efficacy standards (revised version) of chloasma and have skin lesions on the face.
- It is hoped that exosomes combined with 1565 non-ablative fractional laser, blue aurora or micro-needle can improve facial chloasma.
- Fully understand and understand the content and significance of this study, implementation plan, possible benefits, risks and countermeasures, rights and obligations of subjects (including privacy protection, free withdrawal), willing to participate in this clinical study and able to cooperate well, Those who signed the informed consent form.
- Exclude post-inflammatory pigmentation, malar brown-green nevus, Riehl's melanosis, pigmented lichen planus and other skin diseases.
- Subjects who agree not to use other cosmetic treatments related to the study during the study period.

Interventions
After 1565 nm non-ablative fractional laser treatment, patients with melasma were smeared with normal saline and to compared with those smeared with exosomes after laser treatment.
the hUCMSC-Exos were applied while rolling a microneedle roller and to compared with those used 1565 nm non-ablative fractional laser or PBASM combined with hUCMSC-Exos.
After 1565 nm non-ablative fractional laser treatment, patients with melasma were smeared with hUCMSC-Exos and to compared with those smeared with normal saline after laser treatment.What's more,compared with those used microneedles or PBASM combined with hUCMSC-Exos.
a plasma named Peninsula Blue Aurora Shumin Master (PBASM) rolling each area for 8-10 min before applying the hUCMSC-Exos in the entire face. And to compared with those used 1565 nm non-ablative fractional laser or microneedles combined with hUCMSC-Exos.
