Publication number: 20220000752Abstract: An injectable hyaluronic acid composition including a hyaluronic acid; a local anesthetic selected from the group of amide and ester type local anesthetics or a combination thereof; and an ascorbic acid derivative in an amount which prevents or reduces the effect on the viscosity and/or elastic modulus G? of the composition caused by the local anesthetic upon sterilization by heat. Further, the medical and non-medical, such as cosmetic, use of such a composition, and to a method of manufacturing such a composition.Type: ApplicationFiled: September 21, 2021Publication date: January 6, 2022Inventors: Åsa Wiebensjö, Katarina Edsman

Patent number: 10988600Abstract: A hyaluronic acid product is comprising a cross-linked hyaluronic acid and one or more cyclodextrin molecules, and further comprising a guest molecule capable of forming a guest-host complex with the aminocyclodextrin molecule acting as a host, wherein the guest molecule is a retinoid, preferably adapalene, or a RAM BA. The hyaluronic acid is cross-linked by ether bonds, and the one or more cyclodextrin molecules are grafted onto the cross-linked hyaluronic acid by amide bonds, preferably using a triazine-based coupling reagent.Type: GrantFiled: June 20, 2017Date of Patent: April 27, 2021Assignee: GALDERMA HOLDING SAInventors: Katarina Edsman, Jean-Guy Boiteau

Publication number: 20190062461Abstract: Efficient cross-linking of hyaluronic acid (HA) is provided by a manufacturing process. In the process, HA is activated by an initial cross-linking in an aqueous solution. Unreacted cross-linking agent is removed from the activated HA. Cross-linking of the activated HA is finalized, without addition of any additional cross-linking agent, in a suspension of a liquid precipitating medium and the activated HA in precipitated form. The resulting cross-linked HA products exhibit high effective cross-linker ratio and other favorable properties, making the products useful as implants and in medical and cosmetic surgery.Type: ApplicationFiled: August 24, 2018Publication date: February 28, 2019Applicant: GALDERMA S.A.Inventors: Morgan KARLSSON, Katarina EDSMAN
