I would like to know the appropriate re-treatment interval for filler injections in the chin and cheek areas.

Whenever I look in the mirror, I feel like I have a receding chin, and the flatness of my cheeks makes me look lifeless and gives me a dull impression. Therefore, I am seriously considering a hyaluronic acid filler procedure to instantly and smoothly fill in sunken areas and add dimension without surgery.

I understand that these types of minor treatments typically have the characteristic of gradually being absorbed into the body over time, causing the injected volume to decrease little by little. I would like to know approximately how often I should receive filler touch-ups or re-treatments to maintain the beautiful initial design naturally for a long time.

I am also wondering if the interval between re-visits for filler treatments varies significantly depending on whether the product is domestic or imported, as differences in drug cohesion or duration of retention in the body may occur.
