Hyaluronic acid under-eye dark circle removal surgery is suitable for tear trough dark circles and vascular dark circles, both of which utilize the filler effect of hyaluronic acid to fill in the sunken tear troughs or to increase the thickness of the skin as a means of eliminating the dark circles under the eyes. The procedure requires a short treatment time and is less expensive, but it also has a shorter maintenance time and requires multiple injections. Although hyaluronic acid injection to remove dark circles is relatively simple, there are still certain surgical risks, as follows: 1. The operation of this procedure requires high technical requirements on the doctor’s operation, and it is necessary to accurately grasp the amount of injections and the injection level, and if too much is injected, it will lead to bulging of the injected area, and if it is injected too little, the effect will be not obvious; 2. If the injection site is not precise enough, and it is injected into the opening of the lacrimal duct, or into the orbital area and the choroidal muscle, it will easily lead to tear duct plugging, and it will be easy to lead to the tear duct plugging. If the injection site is not precise enough and injected into the opening of tear duct or the orbital and orbicularis oculi muscle, it will easily lead to the blockage of the tear duct or the unevenness of the eye circle after the operation; 3. After injecting the hyaluronic acid, it may produce the phenomenon of temporary slight redness, swelling, itching, etc.; 4. If you do not define the type of your dark eye circle and blindly choose hyaluronic acid filler, not only will it not solve the original problem, but it may also lead to other undesirable situations. If the applicant has dark circles under the eyes because of under-eye depression, blindly choosing hyaluronic acid filling, because the color of hyaluronic acid is slightly blue, after filling, the under-eye blue symptoms may occur.
