Summary

This study looks at how melatonin from lotions and bubble baths enters the body compared to traditional oral tablets. Researchers will measure melatonin levels in saliva after use to see how quickly it is absorbed and how long it stays in the system. The trial involves healthy university students and also tracks any side effects like drowsiness or skin irritation.

What this could mean

Active substance: Melatonin in oral, lotion, and bubble bath formulations
What this could lead to: If this works, it could provide dosing and safety information for melatonin in lotions and bubble baths, helping consumers make informed choices.
What could go wrong: This is a small early-stage study in healthy students, so results may not apply to the general public. Absorption from skin products may vary widely, and side effects like drowsiness or skin irritation are possible.
