What this Trial Is About
Researchers are evaluating a new lip product containing Caulerpa lentillifera extract to see if it can improve the appearance and perception of dark lips caused by hyperpigmentation in Thai adults aged 18 to 60 who are concerned about lip darkening. The trial aims to find out if this product can reduce lip hyperpigmentation compared to the participants' initial condition. Participants will apply the lip product twice daily, once in the morning after breakfast and once before bedtime, for a total of 7 days. They are asked to avoid using any other lip products during this period to ensure clear results. The study does not include any comparison groups or placebos. During the study, researchers will measure changes in lip hyperpigmentation from the start to the end of the 7-day period. Secondary measures include changes in lip dryness and participants' own assessments at the beginning, day 1, and day 7. The study monitors adherence by ensuring participants follow the application schedule and refrain from other lip products.
