Does the hyaluronic acid injection (water light needle) have any effect after just one session?

For skin problems such as dryness and dull complexion, hyaluronic acid injections (mesotherapy) can provide some improvement, such as increased skin hydration. However, this effect is often short-lived and may last only about one to two months. This is because the amount of nutrients introduced with a single injection is limited, and individual differences exist in skin absorption and metabolism of these nutrients. Additionally, the effectiveness is closely related to individual skin condition, lifestyle habits, and the number of treatments received.

Hyaluronic acid injections are a minimally invasive cosmetic procedure that involves injecting a mixture containing hyaluronic acid, vitamin C, B-complex vitamins, and other nutrients directly into the dermis to achieve hydration, skin brightening, and improvement in skin texture. It can stimulate collagen regeneration and improve skin elasticity and luster.

To achieve longer-lasting results, consecutive injections are usually recommended. Typically, 3 to 4 sessions are required, with intervals between injections to allow the skin sufficient time to absorb and adapt to the nutrients. With repeated injections, the effects of hyaluronic acid injections can last about a year, although this may vary depending on the patient's physical condition and post-treatment care.

After receiving hyaluronic acid injections, patients should also pay attention to keeping the injection sites clean and hygienic to avoid infection. Furthermore, performing regular sun protection and moisturizing routines is very important, as this helps prolong the effects of the treatment.
