Do melanoidins induced by topical 9% dihydroxyacetone sunless tanning spray inhibit vitamin d production? A pilot study.

Abstract:

:We report here preliminary pilot study data of the effect of sunless tanning spray with 9% [Correction added after online publication (August 24th, 2009): The concentration of Dihydroxyacetone used in the study was 9% and not 3% as previously stated] dihydroxyacetone (DHA) on 25-hydroxyvitamin D [25(OH)D] serum levels in subjects exposed to controlled amounts of UV-B radiation during April/May in Omaha, NE, 41 degrees N latitude. We found that DHA-induced melanoidins in skin act as a topical sunscreen attenuating the formation of 25(OH)D.
