Kose Maihada was born from a simple Japanese philosophy: your skin's best state is its natural one. Modern life—stress, pollution, harsh routines—can disrupt that balance. So, Kose's researchers in Tokyo looked to a traditional Japanese beauty secret: rice ferment (kojic acid). They developed the Hadajun line to gently reset your skin's foundation without harsh chemicals. This hydrating toner is the heart of that system, formulated with a high-purity, 100% Japanese rice ferment extract. Every batch is made in a GMP-certified facility in Japan, adhering to strict quality controls that exceed international standards. It's not just a toner; it's a return to your skin's inherent clarity and resilience, which is why it consistently ranks as a top-selling hydrating toner in Japan.

The Kose Maihada Hadajun Hydrating Toner features a thoughtfully curated ingredient list centered around Japanese rice ferment (sake) as its key component, which is rich in amino acids, vitamins, and enzymes to enhance skin hydration, improve texture, and promote a brighter complexion. This formulation includes glycerin and butylene glycol as humectants to attract and retain moisture in the skin, ensuring long-lasting hydration and a supple feel. Additional ingredients such as dipropylene glycol and PEG-8 contribute to the toner's smooth application and penetration, while sodium hyaluronate provides deep moisturizing benefits by binding water to the skin's surface. The inclusion of hydrolyzed collagen and elastin supports skin elasticity and firmness, and botanical extracts like licorice root and chamomile offer soothing and anti-inflammatory properties to calm sensitive skin. Preservatives such as phenoxyethanol and methylparaben are used in safe concentrations to maintain product stability. Overall, these ingredients work synergistically to deliver intense hydration, improve skin barrier function, and leave the skin feeling refreshed, plump, and radiant with regular use.
