Even while using the skin regeneration cream, I have doubts: should I keep using it?

I started using a product that is said to be good for skin regeneration, and the first thought that crossed my mind was, "Am I on the right track?"
Since skin regeneration isn't something you feel in just a day or two, it wasn't easy to judge whether or not there was a change.
There are days when the redness subsides and days when it stays the same, so I became curious if this is the normal flow of the skin regeneration process.
I also wanted to know what signs appear first if skin regeneration is proceeding well.
I was also confused about whether the long-lasting moisture was part of skin regeneration or just a simple moisturizing effect.
I used it hoping for skin regeneration, but on days when breakouts actually occurred, I wondered if I should continue using it.
It was difficult to judge whether I should take a break in the middle or if it was right to endure and continue.
I became curious whether skin regeneration is possible with just one product, or if lifestyle habits also need to be managed.
The more I used it, the more I felt that the concept of skin regeneration was not as simple as I had thought.
However, it is true that my skin has become less sensitive than before, so I am currently continuing to monitor the situation.
