In the first few weeks after I quit smoking and started vaping, my face was so dry that my skin got very flaky (especially near my eyes). I drank tons of water and didn't feel dehydrated, but I peeled as if I'd had a bad sunburn on my face or something. It was weird and I still have no idea if it was some early adjustment to PG or just another part of the bizarre changes your body goes through when you quit smoking.
