How long after receiving a hyaluronic acid injection (water light needle) can I wash my face?

　　Hydroquinone injections are generally administered through microneedle injections to deliver nutrients into the dermis layer of the skin, improving its appearance. The usual reference price for hydroquinone injections ranges from 1,600 to 5,200 yuan per session, with visible improvement typically seen after 2-4 weeks. Usually, individuals can wash their face 12-24 hours after the injection, although the exact time may vary.

　　If the hydroquinone injection is administered superficially, the skin trauma is relatively minor, and the recovery time may be shorter. In such cases, it may be possible to gently wipe non-injected areas of the face with a clean damp towel after 6-8 hours, and cautiously wash the face with water after 12-18 hours. Movements should be gentle, avoiding the injection sites, and rubbing or massaging the injected areas forcefully should be avoided.

　　For individuals with weaker constitutions, the recovery time after injection may be relatively longer, so it is recommended to delay face washing, which may need to wait 18-24 hours before washing the face. During this period, touching the injection site should be avoided to prevent an increased risk of infection, while maintaining facial cleanliness, simple cleansing can be performed using a damp compress.

　　In daily life, it is recommended to maintain a light diet and healthy lifestyle. Adequate rest is also important to aid recovery.
