In fact, the filling of collagen requires over-injection, but because "past correction" is unrealistic in clinical use (past correction refers to the over-injection of collagen at the injection site, and sometimes the injection site will be higher than the skin surface), consultants should adopt the principle of "ning more than less" in practical promotion, but inject twice (that is to say, ning more than less when consulting, but not more when injecting, for example, open 6 needles each time, but inject 4 needles for the first time. Or explain clearly to the customer before that it is necessary to strengthen the supplementary injection once every 1-2 months after the first injection, so that the effect will last longer, and the amount of the second supplementary injection is obviously less than that of the first injection.
The collagen we are talking about can last for 12- 18 months, which is the theoretical degradation time of collagen, just as the theoretical fuel consumption per 100 kilometers of an automobile is measured under the specified objective environment such as temperature, wind direction and wind speed, while the degradation time of bimei collagen in a stable laboratory environment is 12- 18. However, due to the differences of individual skin structure, age structure, expression richness and doctors' injection techniques, the maintenance of injection effect will eventually be affected. At the same time, the replenishment and degradation of collagen is a dynamic and balanced process, so it needs to be replenished in real time. Therefore, collagen needs a course of implantation to maintain the effect for a long time and the effect is good.
