Red spots are appearing on my face, probably because of the severe fine dust.

Maybe it's because the fine dust is so bad these days, but if I go outside for even a little while, my face gets really itchy and red spots pop up one by one, just like mosquito bites. ㅠㅠ My skin is on the sensitive side, so it's really upsetting that it reacts like this even with the slightest irritation. Haha. I tried to cleanse quite thoroughly, but my skin just isn't getting back to normal. For the time being, I think I'll have to cut back on outdoor activities and just apply soothing ampoules day and night. ㅠㅠ
