I'm considering getting a collagen booster. Has anyone tried it?

Since turning thirty, there have been many days when my skin looks dry and dull.

In the past, it seemed okay as long as you slept well.
Lately, my makeup hasn't been applying well, and my face looks tired overall.

So I went for a dermatology consultation, but
I became interested because you unexpectedly recommended a collagen booster.

At first, I thought it was simply a procedure to hydrate the skin, but
I heard that it induces collagen production, so your skin condition can change over time.

For those of you who have actually received the collagen booster, what changes did you experience?

The advertisements talk a lot about the effects of improving skin elasticity and texture.
I am curious if there was actually a change noticeable to those around me.

Especially if your face looks sunken
For those of you who were concerned about fine wrinkles, how satisfied were you?

I heard that the advantage of collagen boosters is that they naturally improve skin condition.
Is it like gaining volume like fillers?
Or I'm curious if it feels like the skin itself is becoming healthier.

I've also heard that the effects appear a month or two after the procedure rather than immediately after.
I would also like to know when you felt most satisfied.

There are so many types of products, so I'm curious which collagen booster you received.
I would also like to hear if the pain was bearable.
