Do the effects of the collagen booster tend to improve over time?

I'm looking into various treatments to start skincare, and collagen boosters have been appearing the most. I used to be interested mainly in lifting, but seeing reviews saying that even skin texture improved has made me increasingly curious.

However, looking at the reviews, some people say they saw immediate results, while others say their satisfaction gradually increased over time, so I am curious which scenario is more common in reality.

By any chance, do collagen boosters tend to show better effects after some time has passed rather than immediately after the procedure? I have seen posts saying that collagen is produced inside the skin, but I would like to know how noticeable the effects actually are.

My skin is on the thinner side, so I find drastic changes burdensome and prefer a natural improvement in my skin condition. That is why I think a collagen booster might be a good fit for me, but I am also very worried since it is my first time.

I am curious about the pain, and I also want to know the extent of bruising and swelling. It is also important to me whether I can return to my daily life immediately, so I would like to hear a lot of real-life experiences.

If anyone has recently tried a collagen booster, how satisfied were you? Please let me know if you plan to get it again and what the best changes you saw were. I think real reviews would be much more helpful than advertisements haha.
