I am considering a collagen booster for skin elasticity. What is the actual satisfaction level like?

Lately, I can see my face looking dull and losing elasticity as I lose volume overall. I feel that simple hydration isn't enough, so I am seriously considering a collagen booster treatment that is said to plump up the skin from deep within. I've found that collagen boosters, which encourage the skin to produce its own collagen, look much more natural and better in the long run compared to artificial fillers.

However, I am worried that side effects like uneven volume growth or nodules might occur after the procedure. For those of you who have received collagen booster treatments at a dermatology clinic, how satisfied are you actually over time? I am curious to hear honest reviews from those who have received the treatment regarding their satisfaction and whether they can definitely feel an improvement in fine lines or skin texture!
