Is the satisfaction level with anti-aging treatments for fine wrinkles high?

Lately, I feel like my skin density has noticeably decreased, and the tightness after washing my face has gotten worse. I can really see fine lines popping up one by one. I think I need to go to the hospital now, but I'm actually scared to go. I'm looking into anti-aging treatments.

To be honest, I feel like once you get started with procedures, you can't stop, lol. I'm not sure how much firmer my face will actually become considering the cost. I'd really like to maximize my skin's regenerative power to naturally slow down the aging process...

For those of you who have personally tried an anti-aging treatment that you felt was truly worth the money, please share it. I'm not talking about the temporary feeling right after the procedure, but the kind where you can feel your skin becoming firm from deep within. Also, are there any anti-aging treatments that are safe to start with and don't cause side effects or sensitivity?
