Glycerin is causing flare ups?

I got pure glycerin to help with dehydration because occlusives and HA weren’t cutting it. I went through a lot of the posts here and followed it the way most people apply it, on damp/wet skin or some mixed in with moisturizer. I’m on day 3 now and it was an INSTANT overnight flare up for me. One of the worst ones I’ve had in a while and my skin is so itchy. My routine is all the same and glycerin is the one and only new thing I added, nothing else in my routine breaks me out so there is no possibility that coincidentally something else is flaring me up on the same day I start glycerin. I also notice that it will make my eyes burn slightly even though it’s not where near my eyes, and around my lips as well. Not necessarily a burn but maybe itchy and uncomfortable? Not sure if I need to take this as a sign to give up on the trial.

I also notice that my skin doesn’t absorb it and it will remain oily/sticky (not sure how to describe glycerin texture) all night and when I wake up as well. I have to use micellar water to take it off in the morning and cleanse my skin. Is this how it’s supposed to feel? The first day I definitely did use a little too much since the bottle isn’t a dropped. Last night and today I made sure to get exactly like 2-3 drops worth so it barely was anything and it still feels the same.

For info, I got 100% pure glycerin (veg I believe) from the pharmacy and there are no other ingredients in the list besides glycerin.
