winter skin is a different beast tbh

My skin in summer vs my skin right now are basically two different people. Like in July I was oily, breaking out along my jawline, everything felt heavy. Now it's December and my cheeks are tight and flaky in the same spots that used to get congested. I don't fully understand why it switches like this, I'm not a skin expert. But I've had to change basically everything — lighter stuff just stops working when the heating's on all day. The one thing that's stayed the same is my collagen in the morning. That I haven't moved on. Everything else feels like I'm guessing, honestly.
