Introduction

The principle of hyaluronic acid injections (mesotherapy) involves delivering hyaluronic acid and other nutrients directly into the dermis layer of the skin through micro-injections, thereby increasing the skin's moisture content. The general reference price for hyaluronic acid injections ranges from 1200 to 6500 yuan per session, and visible improvement is usually observed after 2–4 weeks. Typically, patients can wash their face 6–18 hours after the procedure, although the exact time may vary.

The general reference price for hyaluronic acid injections ranges from 1200 to 6500 yuan per session, and visible improvements typically appear after 2-4 weeks. Usually, patients can wash their face 6-18 hours after the injection, although the specific timeframe may vary.

　　For individuals with good skin tolerance who do not experience significant redness, swelling, or pain during the injection process, gentle cleansing may be performed as early as 6-12 hours post-treatment, provided the physician determines the skin condition is stable. When washing the face, use lukewarm water and avoid excessively hot or cold water. Choose a mild, non-irritating cleanser and gently cleanse the face without rubbing or applying excessive pressure on the injection sites.

　　If minor redness or swelling occurs after the injection but is not severe, face washing can usually resume after 8-12 hours. At this time, use a gentle and non-irritating facial cleanser, avoiding products containing exfoliating particles or chemical exfoliants. If the hyaluronic acid injection was administered superficially and caused minimal skin trauma, the recovery period may be shorter. In such cases, the face can be carefully rinsed with water 12-18 hours after the injection.

　　It is recommended to maintain a light diet, healthy lifestyle, and adequate rest in daily life to support the body's recovery process.

Can povidone-iodine be used to wash the face?

Under normal circumstances, povidone-iodine should not be used for facial cleansing. If topical use of povidone-iodine is required, it is recommended to consult a physician. The skin on the face is more delicate compared to skin on other parts of the body and has its own intact skin barrier function, including structures such as the sebum membrane and stratum corneum, which protect the skin from harmful external substances and help maintain skin hydration and normal physiological functions.
