Comparison of skin elasticity test results from the Ballistometer® and Cutometer®

Abstract

Long-term exposure to sunlight changes skin features like amount of facial wrinkling and skin elasticity, which is useful in estimating skin health and age-related changes. Skin elasticity is evaluated by quantitative methods such as the noninvasive suction device Cutometer(®) , which is widely used to evaluate regional body-elasticity differences and correlate these findings with the results of other instrumental data. Few field studies have been done with the Ballistometer(®) device, another noninvasive method for measuring skin elasticity. In this study, we measured the skin elasticity of each subject's forehead, cheek, and volar forearm using two devices with different means of obtaining quantitative measurements - Ballistometer(®) (Diastron Ltd.) and Cutometer(®) (CK electronics). The results from testing with the Ballistometer(®) and Cutometer(®) devices showed that the degree of skin elasticity of the volar forearm is greater than those found on the cheek and forehead. The parameters measured by the Ballistometer(®) showed high correlation patterns. On the cheek skin, the correlation coefficient between Ballisto-parameters and R parameters (R0, R3, R8) was higher than other skin sites. Taken together, R parameters measured by the Cutometer(®) device have been widely distributed in the evaluation of skin elasticity in research and cosmetics. Although the methodologies are different, the Ballistometer(®) device is also a useful tool to evaluate skin elasticity.
