Is it better to use one type of skin booster consistently rather than switching between several different kinds?

When searching for skincare, there are so many types of Rejuran, Juvelook, and various skin boosters
As I watch, I get the urge to try everything one by one.

However, depending on whether your skin concern is dryness, elasticity, or fine lines
I learned that the necessary ingredients or methods may vary.

Rather than following the procedures that are trending at the time
I'm not sure if it would be better to pick one skin concern, try a treatment tailored to it for a certain period, and then check for changes.
