1. After cleansing, pour a coin-sized amount (about 1-2 pumps' worth) into your palm. 2. Gently press and pat the lotion onto your face and neck until fully absorbed. Do not rub. 3. Follow with your regular serum and moisturizer for a locked-in effect. For best results, use both morning and night. Timeline Expectations: Week 1: Skin feels immediately softer and more supple after application, with a noticeable reduction in tightness. Week 2-3: With consistent use, hydration builds. Your skin starts to look more plump and dewy throughout the day, not just right after applying. Week 4+: The cumulative effect of deep, consistent hydration helps improve skin's overall resilience and texture, making it better equipped to handle environmental stressors.

Born from Kose's 70+ years of Japanese skincare research, this refill was created for one simple reason: modern life is tough on skin. Between air conditioning, pollution, and daily stress, your skin's natural moisture barrier needs serious support. Kose scientists developed the Deep Hydrator formula by isolating a specific, high-purity form of Hyaluronic Acid known for its exceptional water-retention properties. Every batch is produced in a GMP-certified facility in Japan, adhering to strict government quality standards. The result is a product that has become a top-ranked refill choice in Japan, trusted by users who value consistent, deep hydration without the waste of a new bottle.

The One by Kose Deep Hydrator Moisturizing Lotion Refill - 150ml by Kose features a thoughtfully formulated ingredient list designed to deliver deep hydration and skin barrier support. Key ingredients include hyaluronic acid, which is included for its exceptional moisture-retention properties, drawing water into the skin to plump and hydrate, thereby reducing the appearance of fine lines and dryness. Glycerin serves as a humectant, attracting and locking in moisture to maintain skin suppleness and prevent transepidermal water loss. Ceramides are incorporated to reinforce the skin's natural barrier, enhancing resilience against environmental stressors and improving overall skin texture. Additionally, botanical extracts such as licorice root and chamomile provide soothing and anti-inflammatory benefits, calming irritation and promoting an even skin tone. This combination of hydrating, barrier-strengthening, and soothing ingredients works synergistically to offer users long-lasting moisture, improved skin elasticity, and a balanced, comfortable complexion suitable for daily use.
