Query: My Armpits are on fire!

I have developed a painful, red rash and burning from only using this product for 2 days. I immediately stopped using this product but I am still experiencing burning and pain and it's been over a week. I have researched this on the internet and have found many similar claims. I contacted the company and they are requesting I send the product (and providing a postage paid envelope) to them for testing. They are also providing a refund or replacement product in exchange. If you have even mildly sensitive skin I would definitely not recommend using this product.
