How many days after a hyaluronic acid injection (water light needle) can skincare products be used?

　　The hyaluronic acid injection (mesotherapy) utilizes micro-needles to penetrate the epidermis, delivering active ingredients directly to the deeper layers of the skin, stimulating collagen production and enhancing the skin's self-repair capability. The general reference price for hyaluronic acid injections ranges from 1500 to 3000 yuan per session. Noticeable improvement can usually be seen after 3-7 days, although possible side effects may include skin redness, swelling, and scarring. Under normal circumstances, skincare products can be used 7-10 days after the treatment, depending on the skin's recovery condition. If you plan to receive hyaluronic acid injections, it is recommended to visit a legitimate hospital and undergo the procedure under the guidance of a doctor. Detailed analysis is as follows:

　　After receiving hyaluronic acid injections, there may be minor wounds on the skin surface. Using skincare products at this time might cause infection or irritate the skin, affecting the healing process. If the skin recovers well, skincare products can generally be used around 7 days post-treatment. When using skincare products, choose mild and non-irritating ones to avoid further damage to the skin.

　　If an individual's physical condition is poor and the skin heals slowly, the time for using skincare products should be postponed, possibly until about 10 days after the treatment. This is because when the skin hasn't fully recovered, it is in a sensitive state, and using skincare products might increase the risk of infection and affect skin recovery.

　　During the recovery period, following the doctor's instructions and resuming the appropriate use of skincare products at the right time will help protect and maintain the treatment results.
