SHIFTHEADS: The Hidden Health Risks Inside Your Makeup Bag
Description
Makeup may look glamorous on the surface, but beneath it can hide serious health risks. Microbiologist Dr. Keith Warriner joins Shane Hewitt to uncover the unseen dangers lurking in everyday beauty products.
From mascara wands to lip gloss tubes, cosmetics often harbor harmful microbes like Staphylococcus aureus, with contamination made worse by humidity and frequent use. Sharing makeup, Dr. Warriner warns, is no different than sharing a toothbrush — and the results can be just as troubling. The discussion highlights how expired or store-tested products become breeding grounds for bacteria and what hygiene practices can help prevent infection.
This conversation reveals the science of microbial growth in personal care products and why awareness is essential for safer beauty routines.
