What would be good for my skin to look dull? Please recommend a skincare product.

Today, on my way home from work, I absentmindedly glanced in the elevator mirror, and was startled by how much more tired and puffy my face looked under the bright fluorescent lights. The fine lines around my eyes were becoming more prominent, and my skin tone had become duller. It really felt like I wasn't what I used to be. I saw the pillow marks I'd made that morning still hadn't faded by lunchtime, and I was like, "Wow, that's impossible." But today, looking at the mirror, I realized I couldn't ignore it any longer. Before, I could just slather on a cheap moisturizer and go to sleep, and my skin would be plump the next morning, but now, even that simple effort just doesn't seem to cut it. So, I'm taking the plunge and asking for recommendations from the community for the essential skincare products I need!

There are so many products on the market, it's hard to tell which ones are truly effective. People around me often recommend lifting ampoules or highly concentrated essences, but they don't often tell me about the products they're actually using, which is frustrating. I'm looking forward to hearing from people who haven't been fooled by advertising and have actually used their own products. I'm particularly concerned about my visibly diminished skin elasticity, so anything with a lifting effect or that can strengthen the skin barrier is welcome. Do you think a simple beauty device that I can use at home would be effective? Maybe it's because the seasons are changing, but my skin has become especially sensitive and dry, so looking in the mirror every morning after washing my face has become a stressful experience. Please recommend some of your most effective skincare products. I'm curious to know what you're all doing to restore your skin condition.
