Hyaluronic acid has just been finished, so avoid touching the injection site until the needle mouth recovers. If there are obvious pinholes, you can stick artificial skin and beauty tape on the affected area to isolate the wound and reduce the possibility of wound infection. Because hyaluronic acid is very absorbent, it will take away the water from the body after being injected into the body. So the skin may feel very dry within a week after playing. It is suggested that wet compress can be strengthened, especially moisturizing mask. Increase water retention, make skin bright, more tender and moving, but avoid wearing skin care products that are too irritating, so as not to cause sensitivity and discomfort. Specifically, it can be summarized as the following nine points: 1 Do not apply hot compress or hot compress to the injection site; 2. Avoid strenuous exercise for a short time after injection; 3. Don't wear makeup or drink alcohol on the day after hyaluronic acid injection. 4. Maintain the general basic maintenance procedures after injection, and don't massage the treatment site specially; 5, within 24 hours after injection, in order to make the shape fixed, avoid contact with the injection site; 6. One week after lip augmentation, try not to touch your lips when eating to avoid the loss of hyaluronic acid due to eating too cold or overheated food; 7. Do not take aspirin, anti-inflammatory painkillers, Ginkgo biloba, garlic, vitamin A, vitamin E, etc. Within one week after injection of hyaluronic acid; 8. Do not sunbathe, sauna, steam room, laser surgery or go to extremely cold places within one week after injection of hyaluronic acid. These may lead to the qualitative change of the filler before it is combined with skin tissue; 9. Remember not to rub it within one week after hyaluronic acid injection, so as to avoid the hyaluronic acid being scattered before it is finalized. Most people can't help but itch and rub the part hard. It is recommended not to touch the injection part within 6 hours after injection.
