Is the satisfaction level with collagen care for skin elasticity generally high?

Now that I am in my mid-40s, I feel depressed because when I look in the mirror after washing my face, I can see my skin getting thinner and my jawline sagging day by day.
I am making sure to use good topical cosmetics and take nutritional supplements, but I think my skin, which has already started to show signs of aging, needs direct collagen care.

I have become very interested in collagen care treatments that deliver nutrients deep into the dermis layer of the skin, making it firm from the inside out.
Putting aside the investment of cost or time, I want to know if you can really feel a noticeable tightening effect when you receive collagen care, and what the level of satisfaction is.

I'm not looking for a plump face like I did when I was young, but I'm wondering if receiving this collagen care will give me a vibrant and healthy-looking impression.
I would also like to ask if it is possible to return to daily life immediately after the procedure, and if there is synergy when combined with other lifting devices and collagen care.

We desperately need honest and detailed reviews from fellow members in their 40s who are consistently receiving collagen care to maintain skin elasticity.
Just like the saying that it is never too late, I want to start investing in solid collagen care for my skin, even now.
