Background And Aims:
We studied longterm application of cream containing green tea extract, to obtain knowledge of its effects on epidermal mechanics by 2-mm diameter Cutometer probe.
Methods:
Using this non-invasive device, we assessed the effects of green tea extract cream on skin mechanical properties. Healthy male volunteers (n=10) were included in this study, which lasted 60 days. The biomechanical properties of the skin were examined by a non-invasive suction device (Cutometer) and the cheeks were defined as the test area.
Results:
Statistically significant (p<0.05) results were notable for the R6 (Uv/Ue) parameter with respect to time (ANOVA); R0, R2 (Ua/Uf) and R7 (Ur/Uf) parameters were found statistically not significant by ANOVA. This study demonstrates that green tea formulation has a certain effect on R6 (Uv/Ue) parameter when applied regularly for a certain period of time.
Conclusions:
These results indicate that the formulation has no pronounced overall effects on skin elastic or biological properties, but significant R6 (Uv/Ue) values indicate that it does have definite effects on the viscoelastic properties of the skin.
