Van Loghem JAJ, et al. - Given that, calcium hydroxylapatite (CaHA) is a commonly used soft tissue filler for aesthetic facial improvement, particularly for the lower and mid-face, authors assessed the safety, efficacy, and complication rates after injections of CaHA to the upper third of the face using a variety of different techniques in this retrospective analysis. They studied the records of adverse events and side effects of patients who had received CaHA in 2016 and 2017. Findings did not suggest any serious complications. They found that CaHA was well tolerated and effective for a range of upper-face indications.
