A night of dizziness after seeing the cafe's life shot... Are the signs of winter always this prominent?

It's already past 10 p.m. It's sub-zero outside, so the winter air streaming through the windows is quite chilly tonight. Honestly, I was feeling a bit down all day because the company cafeteria menu was incredibly bad. Still, I finally cheered up thanks to a close friend and a famously pretty brunch cafe where we managed to snap some great shots. But when I got home and enlarged the original photos taken in brightly lit rooms, I was quite shocked. Perhaps because I'm a sensitive, analytical type who can't ignore even the smallest flaws, the dark spots that had begun to appear under my eyes kept catching my eye. I used to think the UV index would be lower in winter than in summer, so I laxed my skincare routine. Now that I've analyzed my past, it makes sense that my dark spots are getting more intense right now. My skin is already thin and sensitive, so I'm very picky about skincare products, even organizing the ingredients in an Excel spreadsheet. But this time, I'm trying to switch up my routine with more concentrated products. Honestly, I worry that focusing solely on vitamin content or whitening claims might irritate my skin. I've been using a new skincare product for a week now, and I've been taking photos of my skin every morning and evening. Analyzing the ingredients before using it has given me a bit more peace of mind. Protecting a thinned skin barrier while also removing blemishes isn't easy, but are there any of you who struggle with winter blemishes like I do, keeping track of them? I'm curious about the ingredients in your product line.
