Trust Backed by Japanese Science

You're not just trying a moisturizer; you're using a precisely engineered, government-recognized formula from a trusted Japanese lab. The proof is in the certification.

1. **Medicated Designation** — Officially approved as a 'Medicated' product by the Japanese government, meaning its anti-wrinkle efficacy is recognized and regulated. 2. **High-Purity Hyaluronic Acid** — Features a specific, high-molecular-weight Hyaluronic Acid (Sodium Acetylated Hyaluronate) selected for its superior moisture-binding capacity. 3. **Deep Hydration Formula** — A multi-layered hydration system designed to deliver moisture to the skin's surface and deeper epidermal layers. 4. **Fragrance-Free & Colorant-Free** — Contains no added fragrance or artificial colors, minimizing risk of irritation for sensitive skin. 5. **Non-Comedogenic** — Formulated to not clog pores, making it suitable for various skin types. 6. **pH Balanced** — Developed to match skin's natural pH for gentle, effective absorption. 7. **Japanese GMP Certification** — Manufactured in a facility certified for Good Manufacturing Practice, ensuring pharmaceutical-grade quality control. 8. **Patented Moisture Complex** — Incorporates a proprietary blend of humectants and emollients (patent pending) to lock in hydration. 9. **Lightweight, Fast-Absorbing Texture** — A lotion texture that absorbs quickly without a sticky or heavy residue. 10. **Dermatologist Tested** — Tested under the supervision of dermatologists to confirm gentleness and efficacy.

1. After cleansing and toning, dispense 2-3 pumps into your palm. 2. Gently press and pat the lotion onto your face and neck until fully absorbed. 3. Use morning and night for best results. Follow with your regular serum and moisturizer. Timeline Expectations: Week 1: Skin feels instantly softer and more supple, with a noticeable plumpness. Week 2-3: Consistent hydration helps skin look more resilient. Fine lines, especially around eyes and forehead, appear less noticeable. Week 4+: With continued use, skin maintains a deeply hydrated, smoother appearance. The medicated formula works to improve skin texture over time, supporting your skin's natural barrier against daily stress.

In Japan, where skincare is treated as a science, Kose developed this lotion to solve a modern problem: skin that feels dry and looks tired no matter what you try. The goal was a medicated lotion that didn't just sit on the surface but delivered deep hydration where fine lines start. They focused on a patented, high-purity form of Hyaluronic Acid, selected for its proven ability to bind and hold moisture within the skin's layers. Every batch is produced in a GMP-certified Japanese facility, adhering to strict pharmaceutical-grade standards. This commitment to precision is why it earned the Japanese government's official 'Medicated' designation, a mark of trusted efficacy. It's not just another moisturizer; it's a top-ranked anti-wrinkle lotion in Japan, trusted by those who prioritize results over hype.

The One by Kose Deep Hydrator - Medicated Anti-Wrinkle Moisturizing Lotion contains a thoughtfully curated blend of ingredients designed to deliver comprehensive hydration and anti-aging benefits. At its core is the inclusion of hyaluronic acid, a powerful humectant that attracts and retains moisture in the skin, plumping the appearance of fine lines and wrinkles. This is complemented by ceramides, which are essential lipids that help restore and strengthen the skin's natural barrier, improving moisture retention and protecting against environmental stressors. The product also features niacinamide (Vitamin B3), known for its ability to improve skin elasticity, reduce redness, and enhance the skin's barrier function. Additionally, it contains squalane, a lightweight emollient derived from plants that mimics the skin's natural oils, providing deep hydration without a greasy feel. The formulation is further enhanced with botanical extracts such as licorice root and green tea, which offer antioxidant properties to combat free radical damage and soothe the skin. These ingredients work synergistically to deliver intense hydration, improve skin texture, and visibly reduce the signs of aging, making it an effective choice for those seeking a medicated moisturizer that addresses both dryness and wrinkles.
