<![CDATA[Background: Accelerated aging is associated with increased exposure to reactive oxygen species (ROS), leading to lower collagen and elastin levels in the body. This reduction reduces microvascular activity, causing microcirculatory disorders and skin wrinkles. Administering collagen tripeptides can help improve the microcirculation system. Objective: This study aims to investigate the effects of collagen tripeptide on improving microcirculation, reducing skin wrinkles, and lowering excessive ROS toxicity. Method: The research method used is experimental with a pre-post study approach without using a control group and descriptive quantitative data analysis. We measured microcirculation using a microscope, quantified ROS levels with the QYM-DI microscope, and assessed nasolabial fold depth with an acupuncture needle. Results: The study results indicate that collagen tripeptide significantly improves microcirculation, reduces skin wrinkles, and decreases excessive ROS toxicity. The non-parametric Wilcoxon test results are as follows: (1) there is a significant difference before and after collagen tripeptide consumption in terms of microcirculation improvement (p = 0.000), reduction of skin wrinkles on the nasolabial folds (p = 0.008), and reduction of ROS (p = 0.000). This improves microcirculation, which in turn reduces skin wrinkles on the nasolabial folds. Conclusion: Consuming collagen tripeptide for three months can improve microcirculation, reduce skin wrinkles on the nasolabial folds, and reduces ROS.]]>
