Any Skincare Duds?

I've been seeing a lot of people praise products on social media lately, but it has me wondering--everything can't always be 5 out of 5 stars! Do you have any products that you just don't like? Anything you've tried that wasn't working for you? I got two: Zeroid Pimprove toner made me rash and blister. If I use it with the Zeroid Soothing Cream, it works a bit better but what if someone like me only could afford to purchase the toner alone? That would make me instantly not want to buy from Zeroid again--so, giving a chance to pair both products to make it work would be out of question. And Dermalogica daily microfoliant brightening powder!! It cut my skin up pretty bad even when I lightly touched fingertips to skin. I followed all the rules & directions but the micro-rice particles exposed raw, painful patches all over my face after my first initial use. AND it's supposed to be a DAILY use! Ouch!!
