How long does the skin whitening effect of hyaluronic acid injections last?
The duration of the skin whitening effect of hyaluronic acid injections varies among individuals, but generally can last from six months to one year. The detailed analysis is as follows:

Each person's metabolic rate differs, which directly affects the speed at which the active ingredients in hyaluronic acid injections are metabolized within the body. Individuals with slower metabolism may experience a longer duration of effect from hyaluronic acid injections. After receiving hyaluronic acid whitening treatment, if patients maintain good lifestyle habits, such as avoiding prolonged exposure to strong sunlight, regularly performing skin care, adequately hydrating, ensuring sufficient sleep, and maintaining a balanced diet, the effects generally can be maintained for about one year.
If an individual has a faster metabolism, or does not intensify skin care after the procedure, the whitening effect of hyaluronic acid injections may last for a shorter duration, potentially only around six months. Additionally, failure to follow the doctor's recommended course of treatment after receiving hyaluronic acid injections may also affect the longevity of the whitening effect.
To prolong the duration of the hyaluronic acid whitening effect, enhanced skin care is recommended, including regularly using hydrating face masks and skincare products to maintain skin hydration. Apply sunscreen when going outdoors to avoid damage from ultraviolet rays.
