Abstract:
The hazards of the dansyl chloride test are not negligible. We introduce the dihydroxyacetone test as a safe substitute. Several advantages are highlighted including easy and reproducible measurements of the modifications in skin color by chromometry in the L* a* b* (luminance, hue, chroma) mode. The color variations in time as well as the fade-out of DHA-induced pigmentation by some cleansing skin care products are revealed 'in vivo' as well as 'ex vivo' on D-Squame collections of stratum corneum.
