How long does a skin booster usually last?

Hello! My skin has become sensitive lately, so I find myself becoming very interested in skin boosters.

I've only tried Rejuran as a skin booster once, and I felt the effects lasted about two weeks... I heard that the duration increases if you get it three times at one-month intervals, but since it is a procedure with a downtime, it is not easy for me to get it at one-month intervals.

How long did the skin boosters you've tried last? If you know of any long-lasting ones, please share them with me!
