Will skin hydration injections cause swelling?

After receiving hyaluronic acid injections, facial swelling may typically occur, but swelling usually does not appear in other body parts. This is because hyaluronic acid injections involve an invasive method that causes minor local trauma, leading to swelling at the injection site. However, since other areas of the body are not affected, they generally do not swell. If swelling occurs in other body parts, it is advisable to seek prompt medical evaluation at a hospital.
