Due to the risks associated with filling the tear troughs, it is not recommended for some people with severe infections, scarring, etc. to avoid damaging their health. Tear trough filler is a procedure in which filler substances such as hyaluronic acid, collagen, and autologous fat are injected into localized tear troughs to plump up the tear trough area. Its effect lasts for a shorter period of time, requiring multiple injections, and some patients may experience rejection when foreign material is used for filling. However, due to the risks associated with tear trough filler, the surgery is generally not recommended for people with serious facial infections, scarring, allergies, breastfeeding, mental anomalies, and people with serious heart, kidney and other important organ pathologies, so as not to jeopardize their health. Tear trough filler patients should go to the hospital in time if there is infection, hematoma, asymmetry on both sides after the operation, to find out the cause of the disease and actively cooperate with the doctor to take relevant treatment measures.
