Hyaluronic acid is abundantly present in human connective tissue and the dermis. This transparent gel-like substance possesses powerful moisturizing properties, playing a crucial role as a matrix in the skin's dermis layer. It offers filling, hydrating, and wrinkle-reducing effects. In medical aesthetics, hyaluronic acid injections can achieve various results such as nose augmentation, lip enhancement, chin augmentation, and wrinkle reduction. Although minimally invasive cosmetic techniques are now highly developed and mature, the possibility of complications cannot be entirely ruled out.So what are the signs of hyaluronic acid treatment failure, and how can it be corrected?
Sign 1: Persistent localized redness and swelling, with nodules, depressions, or lumps appearing on the surface
Cause: The injector fails to accurately control the injection depth and dosage. If injected too superficially, persistent redness and swelling may occur locally, affecting aesthetics.
Failure Manifestation 2: Hyaluronic acid fails to absorb and migrates freely.
Cause: Injection of counterfeit or substandard hyaluronic acid, or fillers of unknown composition that diffuse to other areas, potentially causing embolism.
Failure Manifestation 3: Skin Necrosis
Cause: Filler injected into a subdermal artery, particularly if it is a terminal branch, causing arterial blockage and subsequent necrosis of the skin in the affected blood supply area. This is often due to unqualified practitioners.
How to repair it?
The key lies in removing the injected substance.
If genuine hyaluronic acid was injected, it can be dissolved using a corresponding hyaluronidase injection without surgery. If the substance is non-dissolvable or counterfeit hyaluronic acid made from unknown materials, surgical removal is necessary.
