Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Adults with self-reported darkened lips will apply the investigational lip product twice daily for seven days and avoid other lip products during the study. Researchers will compare objective baseline measurements (such as imaging) and participant perceptions before and after the 7-day treatment period. The study is conducted at the Faculty of Dentistry, Chulalongkorn University, with screening to exclude lip abnormalities, recent medication use, or known allergies to the product. Outcomes focus on changes in appearance and subjective perception of lip hyperpigmentation.
