Under normal circumstances, if you feel that some parts of your body are not too satisfied after your first Big V thread sculpture, you should wait at least 3 months before you can have a second thread touch-up. Why wait 3 months later? 1, generally small depressions, unevenness, etc. will be in the postoperative period of about 1 month to recover on their own. 2.After 1 month, the superficial threads can play a certain role in wrapping and lifting, and the power is stronger at about 3 months. 3.The effect of the smooth line buried under the dermis reaches its best in about 3 months. Through the above introduction, we can draw such a conclusion: after the carving of the line about 3 months after the effect is more obvious period, this time to determine whether the need to “check and fill in the gaps”. If the postoperative satisfaction is not high at this time, depending on your recovery situation 3 to 6 months later, you can consider doing it again. Perhaps some of the candidates, the big V line is not very understanding: big V line is in fact a short for serrated line, divided into small V line and big V line two different types of line, but because of its bidirectional serrated structure, can be effectively fixed and lifted, can effectively create a V face visual, so it is also known as the “V” line. Of course, small V line and big V line is not just the name of the difference, there are some practical differences: 1, the advantage of the difference small V line: line body is shorter, lifting force is greater, two-way internal and external teeth combined with the effect of more adjustable and plasticity. Big V line: line body thick and tough and strong, serrated two-way both lifting and fixed, can change the skin fascia direction, the use of a wider range, lifting strength, effective time cycle is also longer. 2, the difference between the disadvantages of small V line: the use of a narrower range, limited to orbital facial modification and correction, pain is also more obvious, need to infiltrate anesthesia. Big V line: the needle body must be thick infiltration anesthesia or block anesthesia, easy to bruise as well as pain maintenance time is longer, the operation of the fixed position is very strict, otherwise part of the operation effect is not obvious. 3, adapted to different groups of small V line: eyebrow, eye, mouth, cheeks and other contours of the god modification and local correction. Big V line: anti-aging, firming, lifting and immediate results can be applied. Usually, it can be applied to facial contour, abdomen, buttocks, arms, thighs, etc. It is a widely used line.
