My face has become noticeably dry and dull, so I'm looking into skincare products for firming.

I attended a friend's wedding last weekend, and I was shocked when I saw the photos taken by acquaintances I hadn't seen in a while. Perhaps due to the lighting, the corners of my mouth and eyes didn't look as firm as they used to. I suddenly felt a pang of fear, wondering if this was the beginning of the aging process I'd only heard about. So, starting yesterday, I've been diligently searching for a list of firming skincare products. Honestly, I used to think that as long as I hydrated my skin well, it would always be good, but now I find myself drawn to products that offer nourishment or lifting benefits. I'm also worried that ingredients that are too strong might not suit my skin. Are there any firming products that are gentle yet proven effective? I would especially prefer a formula that isn't too sticky, making it suitable for daily use. Since I'm still a beginner, I have absolutely no idea which brand of firming products to use. By any chance, when did you start worrying about your skin texture or sagging? If you have any "holy grail" products you've tried and been satisfied with, could you share them with me?
