When administered properly, hyaluronic acid injections generally do not cause facial stiffness.
The main component of hyaluronic acid injections is hyaluronic acid, which serves to hydrate the skin and enhance its luster and elasticity. Hyaluronic acid is a naturally occurring substance in human skin. Once injected, it integrates naturally into the skin tissue without affecting facial muscle movement, thus it does not lead to facial stiffness.
However, if excessive amounts are injected, the injection site is improper, or non-standard fillers are used, it may cause facial nerve damage or excessive muscle relaxation, which could lead to facial stiffness. Additionally, if components such as botulinum toxin are added to the hyaluronic acid injection, the botulinum toxin's nerve-paralyzing effect may cause stiff facial expressions. However, this condition generally resolves on its own after some time.
When choosing to undergo hyaluronic acid injections or any other form of cosmetic injection, it is essential to choose reputable medical institutions and experienced, qualified physicians to minimize the risk of complications. If abnormal conditions such as facial stiffness occur after injection, prompt medical attention should be sought for targeted treatment by a physician.
