I'm curious about reviews for collagen care, as I'm starting out with some skepticism.

To be honest, I heard that oral collagen supplements aren't effective, so I'm looking into injecting it directly into my skin. However, I'm skeptical right up to the point of paying for collagen care. Everyone around me says it's great, but I can't tell the difference—is it just temporary swelling that makes my skin look taut, or is it actually making my skin tissue firmer?

My biggest concerns are the foreign body sensation and side effects. If the skin clumps or becomes bumpy inside, it would be worse than not doing it at all. Is the definite benefit of collagen care worth taking these risks? Looking ahead one or two years, I really hope there is a significant difference in skin thickness or sagging compared to someone who hasn't had the procedure. I am curious to hear the candid opinions of those with real experience.
