REDAS to Debut Salon-Exclusive BHB Supplement “BODY RETAINER” at Beautyworld Japan Tokyo 2026

REDAS Co., Ltd. (Head office: Akasaka, Minato-ku, Tokyo; Representative Director: Yusuke Daimaru) will unveil its new salon-exclusive supplement, “BODY RETAINER,” at Beautyworld Japan Tokyo 2026, held at Tokyo Big Sight from Monday, May 18 to Wednesday, May 20, 2026. The company will exhibit at West Hall 3 / W3 A016. BODY RETAINER contains 3,000mg of D-BHB (beta-hydroxybutyrate) per stick, produced from sugarcane through a fermentation process. Designed as inner care that connects professional salon treatments with everyday self-care, it is described by the company as the industry’s first salon-exclusive BHB supplement. *According to REDAS research as of May 2026. Development background: focusing on the everyday time between salon visits While esthetic and beauty salons can deliver visible change through advanced treatments, many salon owners share a common concern: how to design the period between a treatment and the customer’s next visit. BODY RETAINER was developed by focusing on this everyday interval between treatments. The name “Retainer” conveys the idea of maintaining or sustaining. Without relying on extreme dietary restriction, the product proposes a new habit that smoothly connects salon care with at-home self-care. Product concept: a formulation based not on “avoiding intake,” but on “using” the body’s cycle Many conventional diet-support supplements are based on the idea of “not taking in,” such as reducing carbohydrates or calories. BODY RETAINER instead focuses on the body’s inherent metabolic cycle and is formulated around the idea of “using” that cycle. Its core ingredient, D-BHB (beta-hydroxybutyrate), is known as one of the main ketone bodies produced in the body during fasting, when carbohydrates are depleted. The product is built around supplemental intake of D-BHB and a formulation concept that links four axes: metabolism, burning, circulation, and elimination. Four-axis linked formulation: metabolism × burning × circulation × elimination The formulation is designed so that the four axes work in coordination rather than independently, with each ingredient’s role considered in relation to the others. Key ingredients and formulation rationale: - D-BHB Ca/Mg (3,000mg): The core of the formulation. REDAS uses a proprietary formulation combining sugarcane-derived, fermentation-produced D-BHB with calcium and magnesium, selected with consideration for stability in the body. It serves as the central ingredient for supporting condition management during fasting periods. - L-Carnitine (500mg): Burning axis. An amino acid-derived component also found in the body, widely known for its involvement in energy metabolism and highly appealing in the body-care category. The product uses an L-tartrate form with absorption in mind. - Organic prickly pear cactus juice (500mg): Elimination axis. A plant-derived ingredient originating from Mexico, known for containing betalain pigments, a type of polyphenol. It is positioned as a circulation and elimination ingredient with strong affinity for natural-oriented customers. - Long pepper / piperine (6mg): Circulation axis. A traditional pepper-family ingredient long used in Southeast Asia. Its active component, piperine, is known as a bioenhancer, or absorption-support ingredient, and helps support the four-axis formulation. - Pomegranate extract (10mg): Beauty axis. A plant extract rich in ellagic acid, a type of polyphenol, included to support appeal among beauty-conscious customers. *Descriptions of ingredient characteristics are based on general properties of food ingredients and do not indicate specific effects or efficacy. Three distinctive positions: 1. Industry first*: A BHB supplement sold exclusively through esthetic and beauty salons. It is not available at drugstores or online stores and is offered only through salons. The product was developed on the premise of working in coordination with salon treatments, making it a rare inner-care product in the market. 2. Formulation volume designed for treatment days: The suggested usage assumes one stick per day on regular days and two sticks per day on treatment days, equivalent to 6,000mg of D-BHB, allowing flexible use aligned with treatment timing. 3. Designed with salon business compatibility in mind: The pricing is designed with an estimated gross margin of about 50% per bag of 30 sticks and a customer cost of about 350 yen per day, taking both customer continuity and salon profitability into account. *According to REDAS research as of May 2026.
