Query: Possibly Toxic?!?!

I've had this product for a year and have also had allergies start within the past year. I have recently discovered that my mother and I are allergic to this item. I've always been itchy and my skin would get very irritable every time I would have this item out. I then started to narrow it down and realized that I was allergic to whatever this product is made of. If you have sensitive skin or skin allergies, please be cautious of this item!!!!!! I gave this item 1 star due to whatever it's made of causing me an allergic reaction, other than that it works great for what it's made for.
