Are there any side effects of hyaluronic acid injections?

　　The hyaluronic acid injection delivers nutrients directly into the dermis through microneedles, thereby brightening the skin tone and improving skin texture. The general reference price for hyaluronic acid injections ranges from 1600 to 4000 yuan per session, and visible improvements typically appear within one to three months. If the hyaluronic acid injection is properly administered and adequately cared for afterward, there are generally no side effects. However, improper operation or poor post-injection care may lead to side effects. It is recommended to visit a hospital and follow medical advice for treatment.　　

　　Hyaluronic acid injection is a common medical aesthetic treatment that effectively replenishes skin moisture, restoring hydration and is suitable for individuals with dry or dehydrated skin. When performed correctly, hyaluronic acid injections generally have no side effects. Professional doctors can control the depth and dosage of the injection to prevent complications. Additionally, proper daily care can reduce the risk of side effects.

　　However, improper injection techniques, such as inadequate sterilization or individual sensitivity, may cause side effects such as localized redness, swelling, and pain. Moreover, poor post-injection care may lead to bruising at the injection site.

　　It is recommended to keep the injection site clean and avoid strenuous exercise, squeezing, or bumping the area. Maintain a light and balanced diet, and avoid consuming spicy or irritating foods.
