How often should hyaluronic acid injections be administered?

Generally, it is appropriate to receive a hyaluronic acid injection (commonly known as a "water light needle") every 3 to 6 months. The water light needle treatment is a common aesthetic procedure in medical aesthetics. It primarily uses microneedles to directly inject nutritional components such as hyaluronic acid, vitamins, and amino acids into the dermis layer of the skin, aiming to achieve deep hydration, improve skin texture, and brighten skin tone. The general reference price for this procedure is 1,500 to 3,000 yuan per session, with noticeable improvements typically seen within 3 to 7 days. This procedure should be performed at a legitimate hospital. Detailed explanations are as follows:

If an individual's skin condition is poor—for example, extremely dry or dehydrated skin, or visible fine lines and pigmentation issues—more frequent supplementation of hydration and nutrients may be needed to improve skin quality. Additionally, if an individual has a faster metabolic rate, the active ingredients in the water light needle may be metabolized and broken down more quickly, resulting in a shorter duration of effect. In these cases, water light needle injections may be required every 3 months to maintain optimal skin condition.

If an individual's skin condition is already good and only requires regular maintenance of hydration and radiance, or if the individual has a slower metabolic rate resulting in a longer duration of effect from the water light needle, the injection interval can be appropriately extended, with injections administered every 6 months.

After the injection, it is important to keep the injection site clean and dry, avoiding contact with water to prevent infection. Additionally, it is essential to focus on skin moisturization and sun protection, avoiding the use of irritating skincare products and cosmetics to maintain hydrated, radiant, and healthy skin.
