Overview of the “MegRhythm Adhesive Carbonated Series” and Hello Kitty Collaboration Design
In Japan, Kao Corporation’s healthcare brand “MegRhythm” is scheduled to release a limited-edition collaboration with Sanrio’s beloved character Hello Kitty on August 9, 2025. This special edition, the “MegRhythm Adhesive Carbonated Gel Pack FOOT”, will feature an adorable, exclusive package design showcasing Hello Kitty, known for her bright and kind personality cherished across generations.
The MegRhythm Adhesive Carbonated Gel Pack FOOT uses a soft sheet that locks in a generous amount of carbon dioxide*, which would normally dissipate quickly, into a gel. The sheet adheres securely to the skin and stays in place even when moving. It is formulated with refreshing ingredients such as menthol, providing a cooling sensation that lasts for approximately 6 hours. The lavender mint fragrance offers a refreshing feeling perfect for summer. With its limited availability, this product is sure to attract both Hello Kitty fans and those looking for summer foot care solutions.
