What is the duration of the effects and the retouching cycle after the Maypure Collagen Booster treatment?

Hello. I am a member in my 30s seriously considering a procedure to address sunken cheeks and overall loss of skin elasticity. I find plastic surgery that artificially adds volume a bit daunting, but I became interested in the collagen booster treatment because it helps the skin regenerate collagen on its own, making it relatively simple with minimal concerns regarding side effects. However, I have heard from others that while the procedure itself is simple, it is not permanent, so periodic maintenance is essential.

So, here is my question: on average, how long do the effects of a collagen booster treatment typically last after a single session? I am curious if the duration of the effects varies significantly depending on the product's ingredients, individual skin regeneration speed, or age. Also, to maintain that initial firming effect beautifully for a long time, I would like to know roughly how long I should wait before returning for a second treatment before the effects completely wear off. I have heard that for skincare treatments like collagen boosters, you need to get three consecutive sessions at one-month intervals initially to prolong the duration; is this really true? I am asking this because I want to maintain healthy skin for a long time, so I would appreciate valuable advice from those who are knowledgeable or from Maypure staff!
