     ZUG, Switzerland--(BUSINESS WIRE)--Galderma (SIX: GALD), the pure-play dermatology category leader, has announced the launch of Restylane Defyne and Restylane Refyne: the first OBT‑based hyaluronic acid injectables ever authorized in Japan.1,2 The products – designed for injection into the mid-to-deep dermis for the correction of moderate to severe facial wrinkles and folds – are now commercially available in the market.1,2

Restylane Defyne and Refyne leverage the unique balance of softness, flexibility, and support delivered by Galderma’s proprietary OBT – designed to move in harmony with facial expressions while maintaining shape and lift – and are the first and only hyaluronic acid injectables clinically proven to restore youthful facial expressions.1,2,5-11 Restylane Refyne offers a smooth, flexible gel, ideal for delicate, highly expressive areas, while Restylane Defyne provides support for areas such as the jawline and deeper facial folds.1,2,5-11 These launches mark a major milestone for Galderma and represent an important chapter in its JPAC growth strategy, supporting the company’s continuing expansion in one of the region’s most dynamic aesthetics markets.

The Restylane portfolio in Japan now includes four products in total, with Refyne and Defyne joining NASHA-powered products, Restylane Classyc™ and Restylane Lyft™.1-4 This versatile range enables clinicians to meet diverse patient needs, from soft, flexible formulations that smooth fine lines, to firmer gels that deliver contouring and support.1-7,12,13

The approvals of Restylane Refyne and Defyne in Japan were based on two pivotal, double-blinded, randomized, active-controlled phase III studies investigating the products in 171 and 162 subjects, respectively. Restylane Refyne and Defyne met the studies’ endpoints, demonstrating a clinically meaningful improvement in wrinkle severity for up to 12 months, with most patients reporting at least a 1-grade improvement in self-assessment scores after six weeks.1,2

With over 30 years of innovation and more than 77 million treatments administered worldwide, Restylane is highly relevant in addressing some of today’s most significant aesthetic trends and needs, from improving facial harmony following medication-driven weight loss to growing concerns around menopause-related skin health and aging.5,14-17 The arrival of OBT technology in Japan now aligns the market more closely with global Restylane availability, reinforcing the brand’s position as the world’s most scientifically studied and diverse hyaluronic acid injectables range.
