Probiotic-infused beauty products have surged in popularity at natural health stores, prompting many to consider the health of their skin’s microbiome. However, while beneficial bacteria deserve attention, we must also be vigilant about the harmful microbes that may be hidden in our cosmetic bags.
Cosmetic Contamination is a Common Concern
A recent UK study conducted at Aston University revealed that between 79% and 90% of used cosmetics, including items like lipstick, lip gloss, eyeliner, mascara, and beauty sponges, were contaminated with various harmful microorganisms. Notable pathogens included Staphylococcus aureus, Escherichia coli, and Citrobacter freundii, which can pose significant health risks.
Although many of these microbes naturally inhabit our skin without issues, they can become harmful if they enter the body through cuts, scratches, or other breaks in the skin. Applying contaminated cosmetics to compromised skin areas—such as cuts, eczema patches, or burns—greatly increases this risk.
Special Attention to Eye and Lip Products
Risks for the Eyes
The U.S. Food and Drug Administration reports that a number of women develop eye infections due to their cosmetics each year, and some cases can even result in temporary or permanent blindness. Products like eyeshadow brushes, mascara applicators, and eyeliners can harbor bacteria if not cleaned and replaced regularly, heightening the risk of eye infections with each use.
Concerning Lip Products
Due to the likelihood of oral ingestion, lip glosses and lipsticks come with their own set of risks. Furthermore, the delicate lip area is susceptible to cracks, sores, and cold sores, which can allow these pathogens to penetrate deeper into the skin. It’s crucial to avoid using these products near any skin wounds and to discard older or expired lip cosmetics.
The Role of Makeup Tools
Repeated use of makeup brushes and sponges exposes them to our skin’s microbiota during each application. Beauty sponges can also easily pick up bacteria from our hands, making proper washing essential. The Aston University study found that beauty sponges used for applying foundation had the highest bacteria levels, with a staggering 93% never having been cleaned and 64% having been dropped on the floor yet still frequently used.
Essential Beauty Hygiene Tips
- Always wash your hands before applying makeup to minimize microbial transfer.
- Seal cosmetics securely when not in use.
- Clean cosmetic brushes weekly with mild shampoo, especially those near the eyes.
- Wash beauty sponges daily with warm soapy water and allow them to dry completely.
- Avoid sharing makeup and request single-use applicators when sampling products.
- Discard old makeup and applicators regularly.
- Store cosmetics in a cool, dry location.
- Avoid makeup application on open or injured skin.
- If you suspect an eye infection is present, refrain from using eye makeup until healed.
Prioritize Cleanliness
Regularly cleaning our beauty tools is vital for maintaining hygiene. Makeup brushes should be washed weekly with mild shampoo and thoroughly rinsed. To ensure additional cleanliness, swish them in a mixture of one part vinegar to two parts water, as vinegar acts as a natural disinfectant.
Beauty sponges should be cleaned after each use and replaced every three months. After cleaning, ensure that sponges and brushes are completely dried, as damp conditions can foster bacteria growth.
Considerations at the Beauty Counter
Brush and sponge hygiene is critical when trying on products at beauty counters and salons. Research indicates that contamination is rampant, with Staphylococcus aureus found on all brushes and sponges tested, and 70% to 82% contaminated with Pseudomonas aeruginosa. Contamination is mostly due to repeated use without cleaning or replacing tools. Opting for single-use applicators can help minimize exposure to these bacteria.
Refresh Your Products Regularly
Over time, preservatives in cosmetics can break down, allowing bacteria and fungi to grow. This makes using outdated products a risk factor for infection. Alarmingly, a survey found that nearly 98% of respondents continue to use makeup beyond its expiration date, particularly eye mascara.
Unlike in the European Union, Canada doesn’t require cosmetics manufacturers to clearly label products with expiration dates. Therefore, experts recommend discarding cosmetics after three to four months of use.
Helpful Tip
As products age, they become more prone to bacterial contamination. It’s advisable to replace mascara every two to three months, while other products should have a lifespan of no longer than six to twelve months.
