How long after hyaluronic acid injection can you wash your face?

After receiving hyaluronic acid injections, patients are generally advised not to wash their face for 24 hours to avoid bacterial contamination and skin irritation. Since hyaluronic acid releases other components upon injection that can activate the skin, a 24-hour rest period is needed to allow the skin to recover naturally, during which facial cleansing should be avoided. If exposed to external contaminants—such as wearing sweat-soaked clothing or coming into contact with sweat—promptly clean the injection area with a sterile wet wipe. At the same time, it's important to stay hydrated and use appropriate moisturizing toners or lotions, while avoiding excessive moisturization.
