When can I start to feel the effects of anti-aging treatments? ㅠㅠㅠ

I'm considering getting an anti-aging treatment, but I'm really curious about when the effects will start to show. I'm worried that if I get my hopes up too high and don't see any changes right away, I'll be disappointed.

I'm especially confused about lifting-type anti-aging procedures because some say you feel an immediate tightening sensation, while others say it gradually improves over time lol. I've heard that some procedures have immediate effects, while others take time due to collagen production, so I'm curious if there is a big difference.

I want to get an anti-aging treatment timed with an important event, but it's so hard to get the timing right. I'm worried that if I do it too close to the date, I won't see the full effect, but if I do it too early, I'm afraid the skin might come back.

I am also concerned because I heard that swelling or redness after an anti-aging procedure might actually make me look worse for a few days.

For those of you who have received anti-aging treatments, please let me know when you started noticing the effects!! I am also curious about when your skin looks most naturally good.
