How long after a hyaluronic acid injection (water light needle) can I wash my face?
The hyaluronic acid injection, also known as the "water light needle," improves skin quality by micro-injecting hyaluronic acid and other substances to hydrate the skin and fight aging. The general reference price for a water light needle treatment is 2,000-4,000 yuan per session, and visible improvements are usually seen within 3-8 days. Under normal circumstances, patients can wash their face 1-3 days after receiving the injection, with exact timing varying by individual. The details are as follows:

If no abnormal reactions such as redness, swelling, pain, or allergic symptoms occur after the injection, and the physician does not specifically advise waiting longer, then the face can be gently washed with lukewarm water as early as one day after the injection. However, avoid using facial cleansers containing irritating ingredients or rubbing the face vigorously to reduce irritation at the injection sites.
However, if the injection was administered deeper into the skin or involved a larger dosage, the skin's recovery time may be prolonged, and it may be necessary to wait three days or longer before washing the face. Individuals with more sensitive or fragile skin, such as those with dry or sensitive skin types, may also require a longer recovery period and may need to wait at least three days before washing their face.
If considering undergoing a water light needle injection, it is recommended to visit a reputable hospital and have the procedure performed under the guidance of a qualified physician. Additionally, maintain healthy lifestyle habits and avoid smoking, alcohol consumption, and spicy foods.
