| Abstract |
Ashiness
describes a common physiological skin condition that may develop
in people with dark skin complexion. Environmental influences,
particularly cold and dry weather, seem obvious. This condition
has seldom been studied so far. In the present study, skin
ashiness was assessed in 37 black African women by means of
colorimetric assessments and xerosis ratings. Colour changes
were measured by the parameters a* and the individual typology
angle ITA degrees. Xerosis was assessed by visual inspection,
the ultraviolet light-enhanced visualization (ULEV) method,
and the cyanoacrylate skin surface stripping (CSSS) method.
The assessments were performed on ashy skin of the legs and
on the normal looking forehead during the winter season. Ashy
skin was lighter but not erythematous. The ITA-revealed colour
changes were correlated with xerosis severity as assessed by
dry dermoscopy and by the ULEV and CSSS methods. In conclusion,
ashiness due to skin weathering does not appear to be related
to mild inflammation. It corresponds to a peculiar type of
xerosis with reduction in Fresnel reflection by the stratum
corneum. |
