NCT ID NCT07290959

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tested whether a 1-hour indoor light treatment works as well as the standard 2-hour version for actinic keratosis (scaly sun-damaged spots) on the scalp. Fifty-five adults with multiple lesions received both durations on different sides of their scalp. Researchers measured how many spots cleared up after 3 and 6 months, along with pain and skin reactions.

Active substance

methyl aminolevulinate (MAL) cream with white LED light

What this could lead to

If successful, this could make indoor daylight PDT more convenient by halving the treatment time, potentially improving patient comfort and clinic efficiency.

What could go wrong

This is a small, completed study with only 55 participants, so results may not apply to everyone. Shorter exposure might be less effective for some lesions, and individual responses can vary.
