Objectives: Presenting and discussing cases where appropriate technique and correct choose of products were performed in order to obtain jawline definition and to correct mild-to-moderate mandibular bone resorption, with no surgical procedures and with immediate and complete recovery. Introduction: A well-contoured jawline and a proportional well-positioned chin are highly desirable for men and women of all ages, it gives a perception of beauty, youth and other emotional attributes. Injectors have a wide variety of products to choose with different properties and rheologies turning up to be a real challenge to perform the right assessment, using appropriate techniques and, of course, achieving desired results. Injectable fillers and calcium hydroxylapatite can reshape the jawline, lift soft tissues, and improve facial proportions, effectively improving the appearance of the face. Materials / method: A full assessment of the face were performed, understanding the main areas of bone and fat compartiments reabsorption; followed by the injection of dermal fillers with crosslinked hyaluronic acid with diferents rheologies for bones, fat compartiments and mucosa; and injection of calcium hydroxylapatite in the jawline, to provide lift, focal collagen stimulation and improve firmness. 27G needles were used for application in the periosteum and mucosa and 22G 50mm cannulas for safe application in fat compartments. The focal point is in definying which aging process is dominant in each patient. Results: Nonsurgical jawline augmentation using injectable fillers and calcium hydroxylapatite can be effectively and safely performed with adequate background knowledge of the regional anatomy, appropriate patient and product selection and the correct technique. The results are immediate, downtime is virtually zero. Small areas of edema, bruising and discrete pain can eventually occur. Conclusion: Jawline rejuvenation is a key component to global facial aesthetic rejuvenation, but it is still an area of great difficulty for injectors, with poor results and low patient satisfaction. Basic knowledge of anatomy along with proper choice of products and technique provide great results that will be easily reproducible and with a short recovery time, exponentially increasing patient satisfaction.
