Stylage L is a cross-linked hyaluronic gel, non-animal in origin, which incorporates an antioxidant (mannitol), is sterile and apyrogenic, with physiological pH and osmolarity. Stylage L is an injectable implant indicated for filling deep to very deep wrinkles and/or for volume restoration (cheeks, contours of the face, cheekbones) by deep dermal injection in the face. Stylage L can also be used in techniques for rejuvenating the hands by sub-cutaneous injection in the back of the hand. Stylage L should be given by deep dermal injection in the area of the wrinkle or cutaneous defect to be treated, where it will generate volume to fill the injected area. It will be slowly resorbed over time. As precision is essential to a successful treatment, the product must be used by medical practitioners who have undertaken specific training in injection techniques for filling.
