It must be false to say that it doesn't hurt at all. Protein thread will be implanted into muscle. How can it not hurt? But the doctor will give you an anesthetic before embedding the thread, which can relieve most of the pain, and some of them need to be injected with local anesthesia. Thread carving and pulling can tighten the fascia layer. And change the direction of fascia to improve skin tightening. ACMETEA can also stimulate subcutaneous tissue properly, thus activating its own collagen regeneration ability, making skin young and elastic and regaining girlish vitality. At the same time, you can't simply take collagen before and after the operation, which will lead to excessive accumulation of collagen supplemented from the outside and released from the inside under the skin, leading to malignant proliferation of collagen, which is caused by unstable formation of collagen. There is no effect after the operation, and the effect is not obvious. Therefore, it is necessary to take ACMETEA orally anytime and anywhere to increase the tension of tissue and the elasticity of capsule during operation to resist the contraction of capsule, and to supplement and maintain the fiber tissue structure and regenerate new tissue. For example, the maintenance time of line carving in Meilai is one and a half to two years. The maintenance time of general line carving promotion is affected by the wire used, postoperative maintenance, doctor's line carving promotion and other factors. If we pay attention to the maintenance after line carving in our daily life, the effect of line carving can last longer.
