Leesol’s Sleepisol Plus Becomes the First Korean Sleep Device to Receive National Sleep Foundation’s SleepMark Designation.
SEOUL, SOUTH KOREA, August 25, 2026 /EINPresswire.com/ — Leesol, a leading sleep technology company specializing in wearable sleep solutions, today announced that its flagship product, Sleepisol Plus, has received the SleepMark designation from the National Sleep Foundation (NSF), becoming the first sleep device developed in South Korea to earn this prestigious recognition.
The SleepMark designation is awarded by the National Sleep Foundation to products that successfully complete a rigorous evaluation process demonstrating quality, credibility, and alignment with sound sleep health principles. The designation is recognized as a trusted mark for consumers seeking products that support healthy sleep. It represents a significant milestone for LEESOL, strengthening the company’s credibility in the sleep technology sector and providing a strong foundation for its continued expansion into global markets.
“Receiving the National Sleep Foundation’s SleepMark designation is an important validation of both our technology and our commitment to improving sleep health,” said Julie Yoon, Vice President in Leesol. “This recognition strengthens consumer confidence in Sleepisol Plus and provides a strong foundation as we expand into international markets.”
Sleepisol Plus is a wearable headband designed to help improve sleep quality by delivering gentle microcurrent stimulation to the prefrontal cortex. The non-invasive device is designed to support healthier sleep through innovative neurostimulation technology while providing a comfortable user experience.
The product has already demonstrated strong commercial success in South Korea, with more than 50,000 units sold, reflecting growing consumer trust and market acceptance.
Building on this achievement, Leesol plans to launch an aggressive global expansion initiative, beginning with Japan, where the company will strengthen its marketing activities and establish strategic distribution partnerships. The company is also preparing to accelerate its entry into the U.S. market, leveraging the credibility of the SleepMark designation to introduce Sleepisol Plus to a broader international audience.
“As sleep health becomes an increasingly important global priority, we believe innovative, science-based technologies can play a meaningful role in improving people’s quality of life,” Julie Yoon added. “Leesol is committed to making Sleepisol Plus accessible to consumers worldwide through continued innovation and global partnerships.”
