In 2026, sleep aids in South Korea is anticipated to register KRW106 billion in retail value sales and 25.9 million units in volumes, reflecting modest value growth of 1% and a volume decline of 3% amid a gradually declining population and increased competition. The shift from rapid expansion earlier in the decade to steady, value-driven gains indicates alignment with a broader move towards premiumisation and multifunctionality seen in mature categories. The landscape remains highly concentrated, with the leading company accounting for nearly half of all value sales, while regulatory constraints continue to limit the introduction of new ingredients and distribution channels. Success will hinge on developing differentiated products that combine sleep support with additional wellness benefits, investing in user-centric formats and personalisation, and building strong brand equity to maintain consumer trust. A strategic focus on targeted formulations, holistic health positioning, and digital innovation is essential to capture evolving demand in an environment defined by stable pharmacy-led distribution and the growing importance of consumer experience.
