Abstract Background Non-surgical genioplasty is one of the best choices in cases of chin retrusion, and it represents a solution for the aesthetic amelioration of facial profile. Recent concerns arose about the risk of bone resorption and vascular occlusion. Different procedures and products may lead to different results. This study reports the experience of a single facial plastic surgeon (M.G.) using non-surgical techniques to fill the chin. Methods This retrospective study assesses 225 patients injected from January 2019 through March 2024 in private clinics in Milan (Italy), London (UK), and Dubai (UAE). Forty-five patients were injected with hyaluronic acid (Genefill DX 1x1 ml, BioScience GmbH, Dümmer, Germany), 90 underwent a lipofilling procedure, and 90 underwent a Dermgraft procedure, that is, a personalized lipofilling, modified by the main author. Half of the last 180 patients underwent shock waves before fat harvesting. Patients were followed up for 12 months, and facial angles and satisfaction data were analyzed. Three experts scored the results over time. Results After all the treatments, facial angles were corrected, but the maintenance of the results varied for the different treatments. Notably, at 3 months, the levels of satisfaction were higher for the HA filler treatment, while at 1 year, the levels of satisfaction were very high for the Dermgraft. Conclusions Liquid genioplasty is a safe technique to correct chin retrusion, with good results and high levels of patient satisfaction. The maintenance of the results varies according to the type of product injected. Level of Evidence V This journal requires that authors assign a level of evidence to each article.
