There are now many injectable implants for face remodeling since the first product appeared in Europe in 1984. The treatment regions most in demand are the cheeks, jaws, lips, and the oval of the face. The aging process is due to fat resorption over the upper two thirds of the face, in addition to the loss of elasticity. Weakness in the skin and subcutaneous fascia becomes more apparent over the lower third of the face. The fat loss together with the slack skin gives the impression of gauntness and loss of volume under the eyes (i.e., the zygomatic and palpebral areas). Treating the zygomatic bone area and subcutaneous tissue by injecting filler products will increase volume around the zygomatic malar bone and subcutaneous area. To choose an implant, we must take into account the patient's wishes, hopes (whether temporary or long-lasting effects are required), age, skin type (dry, moist, greasy, thick, or thin), and the patient's medical history to prevent obvious contraindications in the choice of implant due to type of product, especially in the case of allergies, inflamed areas, or any suspicion of autoimmune disease or recent infection.
