The effect of face-lifting needle injection is not permanent: usually after three to six months, the therapeutic effect will gradually disappear, and then if you want to get the original effect, you must accept another injection. So many people will have injection dependence after injection, which has also evolved into a new type of mental illness. Simply put, it needs to be injected about three times in the first year and once a year for the next two years. If the effect is good, it can be permanent, so many women want to know if there are any side effects from long-term injection of face-lifting needles.
