How many times should one receive hyaluronic acid injections in a year?

Hydrofiller treatment mainly delivers nutrients such as hyaluronic acid, vitamin C, and amino acids directly into the dermis via injection, replenishing essential nutrients and moisture for the skin. It stimulates the regeneration of subcutaneous elastic fibers, achieving skin tightening and maintaining smooth, hydrated skin. The effects of hydrofiller injections typically last around 3 to 6 months, although the exact duration may vary among individuals.

For injection frequency, it is generally recommended to undergo treatment every 3–4 weeks, with 3–4 sessions comprising one complete course. This is because the skin's metabolic cycle is approximately 28 days, and following this cycle helps better stimulate the skin's self-repair mechanisms, achieving optimal results.

Before deciding on the injection schedule for hydrofiller treatment, it is advisable to first consult a professional dermatologist or aesthetic medicine specialist to develop a suitable injection plan based on individual conditions. Additionally, proper post-treatment skincare is important, including using gentle skincare products to maintain hydrated and smooth skin.
