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°N latitude. We found that DHA‐induced melanoidins in skin act as a topical sunscreen… Expand
Effect of Simultaneous Administration of Dihydroxyacetone on the Diffusion of Lawsone Through Various In Vitro Skin Models
This study confirmed that combined DHA and lawsone provided effective blocking of ultraviolet light through products bound in keratinized tissue and suggested further in vitro and in vivo study is required to determine the safety of this system. Expand
Dihydroxyacetone: An Updated Insight into an Important Bioproduct
An updated bioeconomy perspective into a valued bioproduct (DHA), whose supply and production from glycerol, it is argued, will rapidly expand and diversify, with important global health benefits. Expand
Structure/Property Relationship for Ethylenediamine Derivatives as Aids in Sunless Tanning
This report covers an effort to identify adjuvants to the sunless tanning action of dihydroxyacetone. The readily available derivatives of ethylenediamine were systematically studied for their colo...
Chapter 2 – C3-Monomers
Glycerol is successfully converted by the chemical industry into C3-monomers, which are then used to make valued polymers or directly used to produce formulations in high demand. The said monomersExpand
A review of common tanning methods.
Some of the most common tarining methods used in the United States today as well as some potential methods currently under study are summarized. Expand


Sunscreens suppress cutaneous vitamin D3 synthesis.
Results indicate that the sunscreen interferred with the cutaneous production of vitamin D3, and prevented the photoisomerization of 7-dehydrocholesterol to previtamin D3 in human skin slices in vitro. Expand
The Maillard Reaction for Sunlight Protection
This reanalysis of the original notes of a previous clinical study of the melanoidins produced by DHA followed by naphthoquinone in the keratin layers of the epidermis of minimally pigmented Caucasian photosensitive patients determined that these patients received a minimal UVB photoprotection of SPF 18 or more.

Ultraviolet-B radiation increases serum 25-hydroxyvitamin D levels: the effect of UVB dose and skin color.
The response of 25-OH-D levels to UVB light is dependent on skin pigmentation and the amount of UVB given, and useful increases in vitamin D status can be achieved by defined UVB doses small enough to produce only minimal tanning. Expand
