I'm curious about reviews for collagen care!

As I get older, I am very concerned because the overall volume of my face has noticeably dropped and my skin is thinning. Even though I diligently apply highly-rated cosmetics, I don't feel like the nutrients are penetrating deep into my skin, so I am seriously looking into collagen care treatments, which are said to be the hottest trend at dermatology clinics these days. Since the equipment and injection ingredients vary so widely from clinic to clinic, I feel completely lost as a beginner trying to decide which one to choose. I am extremely curious to hear vivid, real reviews from those who have actually paid for and consistently received collagen care treatments.

Please share your honest review. Did you truly feel the skin becoming firm and plump from deep within the dermis, rather than just having a shiny surface for a few days? Also, were there any potential side effects? In particular, can this type of collagen care be a fundamental and effective solution for someone like me with thin, dry skin that easily develops fine lines around the eyes and mouth?
