A Preliminary Report on the Safety and Efficacy of a Novel MaiLi HA Filler for Facial Correction of Wrinkles, Folds, Volume and Lips

Abstract

Introduction: The principal author was given the opportunity to assess new hyaluronic acid filler, first before its European Commission labeling during clinical investigations in France, and then after its European Commission labeling in his clinical practice in Geneva, Switzerland. This hyaluronic acid gel benefits from the world’s first patented OxiFree™ technology. This article sought to present preliminary safety and efficacy data from the first private patient series treated in Geneva with this cross-linked hyaluronic acid gel, called MaiLi. Material and methods: Like most of its competitors, MaiLi is available in various variants, including gel for filling fine wrinkles, for deeper wrinkles, folds, and for lip enhancement, in addition to gels for volumizing indications. This cohort study encompassed patients from the authors’ private esthetic clientele in Geneva, Switzerland. Depending on the indications, the injections were performed according to previously described techniques, ranging from the “blanching technique” to deeper injections. Results: Between January and November 2021, overall 45 patients aged 56 years on average were injected MaiLi gels, according to the areas they wished to be treated, with a follow-up period ranging from a few days to 12 months. Based on our current dataset, we confirm that MaiLi fillers have proven very safe, causing no unexpected undesirable effects. The gel’s hold over time related to its remarkable projection capacity was excellent, resulting in quite natural outcomes and a perfect integration into the tissues. These beneficial effects were still evident at 1-year follow-up. Conclusion: The MaiLi hyaluronic acid fillers proved to be well tolerated and safe, with long-lasting effects. Remarkable properties revealed in this follow-up were their projection capacity and suppleness, as well as their ease of use and longevity, resulting in full patient satisfaction. No relevant undesirable effects were observed. There were no edematous reactions following the injections, nor were there any lymphatic circulation disorders.
