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

ABSTRACT

BACKGROUND: 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. METHOD: 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). RESULTS: 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. CONCLUSION: 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.
