NCT ID NCT07725900

First seen Jul 24, 2026 ยท Last updated Jul 24, 2026

Summary

This large-scale trial is testing whether a topical cream containing epigallocatechin gallate (EGCG), a compound from green tea, can reduce facial redness (erythema), dark spots (melanin), and improve skin moisture. Over 300 participants will apply the cream twice daily for 84 days, while a smaller control group receives no product. Researchers will measure changes using specialized skin sensors to see if the cream delivers visible improvements.
