The present study has provided interesting results regarding
the effects of dried brewer’s yeast on the skin. Yeast first improved
moisture content of the skin, and second improved elasticity. For
moisture content, the significant improvement in the subjective
symptom “desiccated and gritty skin” was supported by the
improved moisture content of skin as determined by SKI and PSI.
This finding appears highly reliable, since dose-dependence was
confirmed in the 3 groups, i.e. the control group as well as Groups
E-9 and E-30. For elasticity, measurements with a Cutometer and
SKI confirmed the significant improvement in elasticity. Among
Cutometer-related parameters, results showed that the most
reliable, R2, was significantly different between Group E-30 and
the control group at 8 weeks, which also supports the reliability of
these findings.
