I'm looking for some skincare tips because I feel unfamiliar with my reflection in the mirror.

Lately, I've been feeling frustrated because my complexion looks unusually gloomy and my makeup doesn't seem to go on well when I look in the mirror. Recently, I was at a department store and was shocked by my reflection under the bright lights, staring at myself for a long time. I used to be able to just apply basic skincare products, but now I think it's time to get more systematic. So, I've been thinking about learning at least one of my own skincare tips and putting them into practice. Especially with the changing seasons, my skin texture has become rough and I've noticed a lot of dryness inside, which is really troubling me. Do you have any skincare tips you use to soothe and moisturize your skin during the changing seasons? I'd love to hear about effective mask pack use or any special products you recommend. Even if it's just a small habit, if you have any tips for maintaining clear skin, please share them with me. I'd be grateful if you could share them with me. I'll be eager to hear your thoughtful responses!
