Watch Out, Expired Makeup Products Can Cause Serious Health Problems

Wondering how you got that rash on your face? Your expired makeup can possibly be the reason behind your unfortunate skin problems. According to a recent study by London Metropolitan University scientists, expired cosmetics actually carry more bacteria than you probably imagined. To be more exact, old makeup products tend to contain ubacterium, aeromonas, and propionibacterium, which can lead to health issues including bacterial vaginosis, gastroenteritis, wound infections, acne, and other skin conditions. While expired concealers and foundation can cause facial blisters or rashes, old mascaras can trigger problems such as pink eye.
