Changes in skin mechanical properties after long-term application of cream containing green tea extract

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
