Please tell me about the effects of collagen care!

As I get older, I really feel the importance of collagen, so lately I've been making sure to take collagen supplements and applying plenty of lotion! However, I've heard that it's difficult for the skin to see significant collagen care effects with just this amount. I looked it up and found that getting professional care at a clinic is much faster and more effective. If I want to see real collagen care results, that must be the right approach, right? I heard that laser or injection therapies are the best for seeing direct collagen effects; I assume they will tell me more if I ask during the consultation, right? I'm really curious to hear genuine reviews from people who have had these procedures. Can you actually feel the effects clearly?

It seems like the cost is quite steep, so if I'm going to get one anyway, I'd like to choose a treatment that is cost-effective and provides long-lasting collagen care effects. If anyone has any information, please share it! I would also be very grateful if you could tell me what criteria I should use when making a choice!!
