Do you tend to set criteria when choosing a skin booster?

Many people are getting skin boosters these days. There are more types than I expected, but it seems the standards aren't clear.
I see Juvelook and Rejuran quite often, and I am curious about your criteria for choosing them.
I thought Juvelook might be good for pores or elasticity, but since there are also many reviews for Rejuran, I am curious which one is better, or if there are any criteria for which one is better for certain areas.
If anyone has experienced both procedures, it would be great if you could share your thoughts on what differences you actually felt.
I would also like to know if there are differences in pain, redness after the procedure, or recovery period, and when you each started to feel the effects.
I am also curious if there are cases where the two are received alternately or managed together.
If there is no clear difference, I would appreciate your opinion on what criteria should be established.
