About a week ago, I purchased one of your foundations, but after using it for a few days I found it gave me a rough, dry, bumpy rash all over my chin, which then spread to my lip and cheek area. I am sure that it was the foundation that caused it because I really only use the product on my chin, and that's the only place where the rash appeared. My skin has never done something like this before, so I'm convinced it has something to do with your product, "Revlon Colorstay 24-hour wear" for combination/oily skin. (the product is in the shade 110 and has an SPF 15). If possible, I would like a refund for this product, as I am no longer able to use it. If not, it's completely fine- I just wanted to let you know that your product causes rashes like this. Thank you for your time
