Has anyone tried the collagen booster? I'm curious about the satisfaction level.

Has anyone here tried a collagen booster treatment? I've been looking into collagen boosters lately because I'm concerned about skin elasticity and fine lines, and I'm really curious about how effective they actually are. There seem to be many types of collagen boosters, so I'd like to know which products or procedures are commonly used. In particular, I'd like to hear personal experiences regarding whether the results are noticeable immediately after the treatment, or if the improvement is gradual over time.

Also, what is the overall satisfaction level with collagen boosters? I'm feeling confused because some people around me say they are good, while others say they didn't live up to their expectations. It seems the price range for collagen boosters varies significantly by clinic, so I'm curious about how much I should generally expect to pay per session. I'd also like to know if buying a package makes it much cheaper.

The duration of the collagen booster's effects is also important. I would appreciate reviews from those with actual experience regarding how many months the results last and how often re-treatments are required.
