I was just wondering in the middle of the night... Could you share your winter whitening routine?

It's already well past 11 p.m. The heater is warm in the room, but I think I lost my lip balm, and my lips are feeling parched... Maybe it's because of the dry winter, but my complexion has been particularly dark and dull lately, and I sigh every time I look in the mirror. They say it's especially important to have a proper whitening routine in times like these. However, it's harder than I thought to achieve both moisturizing and whitening, so I'm at a loss. What whitening routine do you use to maintain your skin tone in this cold weather? I'm worried because I've been noticing blemishes creeping up. If you have any secrets to a whitening routine that has definitely brightened your complexion when you've followed it consistently, please share them with me. I'm asking this question on a sleepless night because I want to hear from those who put a lot of effort into their skincare routines...
