Is a collagen booster suitable for concerns about skin elasticity?

I have an inquiry about collagen boosters. My face isn't sagging severely these days, but I feel like my cheeks have lost some of their firmness compared to before, so it's subtly bothering me.

Especially when I take photos, my facial features aren't as sharp as they used to be, and I feel like I look tired overall.

I'm still a bit hesitant about getting a lifting procedure, so I'm looking into ways to keep my skin firm first. While searching, I noticed that collagen boosters are frequently mentioned for improving elasticity and skin condition. Would it be worth getting a consultation for someone like me who is concerned about the initial stages of losing elasticity?

My skin is on the thinner side, so I'm worried about overly irritating procedures. I'd prefer a look that gives a natural plumping effect. I'm also curious how many sessions of a collagen booster are typically needed to see results. What should I mention before the consultation? Please let me know!
