Will my face swell after receiving a hyaluronic acid injection?

　　Water light needle treatment involves using microneedles to directly inject nutrients such as hyaluronic acid, vitamins, and amino acids into the deep layers of the skin, aiming to achieve deep hydration, brighten skin tone, improve skin texture, and stimulate collagen production. The general reference price for water light needle treatment is 1,500–3,000 yuan per session, with visible improvement typically occurring within 3–7 days; however, possible side effects include skin redness, swelling, and infection. In general, facial swelling may occur after receiving a water light needle injection, but it can usually resolve naturally over time. It is recommended to visit a正规 hospital and undergo the injection under the guidance of a qualified physician. Detailed explanation is as follows:

　　As water light needle injection is an invasive procedure, it causes tissue damage during the process, including possible injury to blood vessels and nerves. Therefore, bruising and swelling at the injection site are considered normal postoperative reactions, and such swelling generally subsides gradually over time. Additionally, improper post-injection care may lead to secondary bacterial infection, causing inflammatory reactions in the face, with symptoms such as swelling or pain. In such cases, antibiotics such as amoxicillin capsules, roxithromycin tablets, or azithromycin granules should be taken under a physician's instructions to control the infection.

　　After receiving a water light needle injection, proper skin cleansing and care are essential. Avoid getting the injection sites wet too soon. At the same time, adequate rest is necessary to help the body recover.
