You may just want to take your chances at ordering a brand new lipstick than trying one of those samples at the store, even if you aren’t sure it’s the right color for you. One out of every five samples at makeup counters and stores is infected with mold, yeast and FECAL matter. They also contain strains of bacteria that can make you sick. The biggest culprits you need to avoid at all costs are brushes, foundations, and eye makeup – but to be on the safe side, never test anything on your face, lips or eyes directly and always use a disposable applicator. I think I feel sick just finding out about this new research. YUCK!
