How should I take care of my skin in winter?

Hello. I'm an office worker who usually doesn't pay much attention to my skin. Lately, the weather has gotten colder, and with the heater constantly on in the office, my skin hasn't been what it used to be...ㅠ

It's normal for my face to feel tight after washing my face, and recently, when I look in the mirror, I see freckles and blemishes starting to appear around my cheeks that weren't there before.

​Maybe it's because I'm a man, but I'm not good at taking care of my skin. Until now, I've just been roughly applying an all-in-one lotion, but now I'm worried that this alone isn't enough.

​

​I'd like to ask for recommendations for moisturizing creams or ampoules that are good for working men.

Can laser treatment be effective for freckles that already exist?
