Recommendations for the treatment of tear trough deformity with cross-linked hyaluronic acid filler.

[BACKGROUND] Recent years have seen a growing interest in the appearance of the eyes among the concerns expressed by patients in cosmetic clinics. This has led to an increase in the frequency of diagnosis of tear trough deformity, and, as a result, the number of treatments performed by specialized professionals has also risen. Hyaluronic acid filler injection is a rapid, nonsurgical technique that gives good long-lasting, but not permanent, results. However, to achieve optimal results, the attending physician must have good anatomical knowledge of the area and involvement of the structures in the tear trough, carry out proper clinical assessment of the patient, and use an appropriate injection technique with the right product.

[AIMS] To support good practice among the professionals who carry out these procedures, this interdisciplinary consensus document describes the relevant issues and recommendations, in order to improve safety standards and to help successfully resolve this aesthetic problem.
