Abstract:The etiology and pathophysiology of delayed inflammatory reactions caused by hyaluronic acid fillers have not yet been elucidated. Previous studies have suggested that the etiology can be attributed to the hyaluronic acid filler itself, patient immunological status, infection, and injection technique. Hyaluronic acid fillers are composed of high-molecular-weight hyaluronic acids that are chemically crosslinked using substances such as 1,4-butanediol diglycidyl ether (BDDE). The mechanism by which BDDE crosslin… Show more
