The demand for beauty products at a discounted price has already led to the dangerous counterfeiting of some of our favorite brands. But according to a report by the National Health Federation, even legitimate products sold through these sites can pose a risk to our health.

USA Today explains that dozens of types of beauty products for sale on discount or auction sites have been stolen straight from drugstore shelves. This opens the door to possible contamination and spoiling of these temperature-sensitive items, which when used, can cause skin irritation and possible infection.

The bottom line? The pennies you save on these discounted products are not worth the risk to the health of your skin. Stick to the clearance sections at online drugstores, which are required by law to regulate their quality of their products.
