Introduction The facial beauty is not easy to define, yet it is paramount to assess the needs of each patient to propose an appropriate treatment plan that will provide beautification or rejuvenation in a natural-looking fashion. One of the beauty aspects easily recognized is the face shape, which can give a perception of age, gender, and attractiveness, and reflects the facial anatomical structure. Because addressing the structure of the face is the basis for the aesthetic approach with dermal fillers, we find the identification of the patient's face shape to be a very good starting point in the facial assessment. Objective To discuss important aspects of facial beauty, the characteristics of the different facial shapes (oval, heart, round, and angular), and a method of planning the aesthetic treatment with injectable fillers based on the strengths and weaknesses of each morphology of the face, that is called the AB face technique. Methods In this study, we describe seven clinical cases: two cases each of oval, heart, and round, and one case of angular shape. Results The evaluation of the face shape can help us define the priorities of the aesthetic approach, determining the areas that need to be restored in the aging face, as well as which areas could be enhanced in the younger patient. Conclusion This approach can be helpful in proposing the aesthetic treatment plan with injectable fillers to provide beautification, rejuvenation, and enhancement of the facial structure, which may benefit facial contours through aging.
