Many female friends have a backward chin or no chin, which leads to a soft face curve. The popularity of chin injection has avoided the pain of traditional surgery, so it has been liked by more and more people. So, how to quickly reduce swelling? Dalian Dongping plastic surgery expert tells you. Temporary slight redness, swelling and itching may occur after injection of hyaluronic acid, but these maladjustments usually disappear after a few days. Hyaluronic acid has few side effects, and it is not protein, so the probability of allergic reaction is much smaller, and it is easily decomposed by human body, so it has no long-term side effects on human body. What should I pay attention to when injecting hyaluronic acid into my chin for a few days to reduce swelling? For the perfect effect of the operation, do not expose the treatment area to extremely hot environment after the operation, such as sunbathing or sunbathing or being in extremely cold places. Please avoid touching the injection site within 6 hours after operation. During this time, you can gently clean it with water and soap, and slight makeup removal is allowed. Because of the rich blood circulation in the face, the swelling is more severe after trauma, but it is also faster after chin augmentation. After chin augmentation 1-2 hours, it began to swell, reached the peak in about 24 hours, stopped in 48 hours, began to fade in 72 hours, and gradually reappeared in one day. Because everyone's physique is different, this swelling reaction is light and heavy, and the light is not obvious. The heavy one, the chin flattened, as if the chin had never been lifted, and even the lower eyelid was swollen, but the swelling was painless and subsided quickly. Hyaluronic acid is one of the components of human skin dermis, and it has no side effects.
