What kind of skin care products do you recommend for this season?

I'm really curious about how you all take care of your skin on these cold winter nights. I stopped by a convenience store on my way home from work and bought a new, trendy bungeoppang (fish-shaped bread) snack... As I slowly ate it and looked in the mirror, all I could feel was a pang of disappointment. I love sweet snacks, but my skin is so dull and dark, and it's frustrating. Now that I'm in my 50s, I feel like the signs of aging are showing through in the form of freckles, and I'm really worried these days. I wonder where you all get recommendations for freckle care products, and if there are any gentle products you can trust. I'm hesitant because I'm always afraid of using anything that might ruin my complexion, and I'm also quite timid. If anyone has tried it and found that their complexion has brightened, please share your freckle care recommendations. I feel like stress is taking a toll on my skin, having spent every night sighing in front of my vanity. Before this winter is over, I'd like to receive a recommendation for a reliable skin care product so I can welcome spring with a bright, cheerful face like before. I respectfully ask for your help. Everyone, please take care of your health in this cold weather...
