Yeah you’re going to want to stop using that shower gel. That makes even MY skin crawl when you said it’s slimy. Shower gels have no rights to being slimy. They’re supposed to be gel like hence the name 🤦‍♀️

Could be they might’ve changed the formula since you last used it? I noticed a few things in my usage of things whether moisturiser or whatever the one item that worked so well a company will just up and change the formula, screwing up the customers who liked their product before the change. I wonder if this might be the case for you?
