Yuuka Co., Ltd., headquartered in Onojo, Fukuoka Prefecture, announced that its tea-based skincare brand Chasumi will begin accepting advance reservations for “Chasumi Medicated Wrinkle Premium Gel” on May 14, 2026. The product targets mature skin concerned with wrinkles, dark spots, and visible signs of aging. According to the company, aging skin tends to accumulate old keratin on the surface, become harder, and allow beauty ingredients to penetrate less effectively, making skincare results harder to feel. Yuuka describes the new item as a special, top-tier all-in-one gel designed for such concerns. Chasumi Medicated Wrinkle Premium Gel comes in a 50g size and is priced at 8,200 yen including tax. A launch campaign will run until June 30. The product claims to offer eight functions in one: wrinkle-improving cream, intensive lotion, whitening serum, whitening cream, mask, calming cream, décolleté cream, and night cream. Key features include Yuuka’s proprietary double tea extract formula, combining fresh tea leaf extract with high-catechin tea extract. The extracts use pesticide-free organic tea grown in Kagoshima Prefecture. The product also claims to provide three-step hydration after cleansing by softening the skin, distributing moisture, and locking it in. For active ingredients, the gel uses niacinamide for wrinkle improvement, tranexamic acid to suppress melanin production and help prevent dark spots and freckles, and dipotassium glycyrrhizinate derived from licorice to prevent rough skin. It also includes selected beauty and moisturizing ingredients such as fast-acting vitamin C, sustained-release vitamin C, hydrolyzed hyaluronic acid, yuzu ceramide, jojoba oil, olive oil, lily extract, meadowfoam oil, and Lamella Drop. For product inquiries, customers can contact Yuuka Co., Ltd. at 0120-64-4318 from 9:00 a.m. to 9:00 p.m., excluding year-end and New Year holidays.
