A leading beauty expert is warning that sharing lip balm or dipping your fingers into tins like Vaseline could be exposing you to bacteria, cold sores and even fungal infections.
Danielle Louise, a beauty specialist on Fresha, the world’s leading beauty and wellness booking platform, says lip products are one of the dirtiest items in our handbags — and that the habit of sharing or “finger dipping” is a hygiene nightmare.
“People use the same tin of lip balm all winter without thinking — or worse, pass it to a friend,” says Danielle Louise. “But once it’s touched someone else’s lips or fingers, it’s contaminated. You wouldn’t share a toothbrush, and the same logic applies here.”
The hidden hygiene horror of lip balm
Danielle says balms and glosses are perfect breeding grounds for bacteria, especially those stored in warm, damp environments like handbags or coat pockets.
Here’s what might be lurking in your favourite tin:
- Herpes Simplex Virus (HSV-1): The virus behind cold sores — spread easily when shared.
- Staphylococcus (Staph) bacteria: Can lead to cracked, inflamed lips or small sores if transferred.
- Fungal infections: Candida and other yeasts thrive in balms that are constantly opened and closed with unwashed hands.
- Mould spores: Can form in older or heat-exposed balms, even if they still smell fine.
- Cross-contamination: Dipping fingers straight into pots like Vaseline or lip scrubs introduces germs that multiply fast inside oily or waxy products.
“Every time you touch your lips, eat, or handle your phone, those bacteria end up on your fingers,” adds Danielle. “When you dip them into a balm tin, you’re feeding that bacteria — and putting it straight back on your mouth.”
Danielle Louise, a beauty specialist on Fresha shares her top tips
- Never share lip balm or gloss – ever.
- Avoid tins and pots if possible; choose squeeze tubes or sticks that minimise contact.
- Wash hands before application or use a clean cotton bud to scoop product.
- Replace balms every 6–12 months — sooner if they’ve melted or changed texture.
- Wipe twist-up balms with a tissue and disinfect occasionally using isopropyl alcohol.
“Lip care is self-care,” says Danielle on Fresha. “A little hygiene goes a long way — especially when it comes to something that literally touches your mouth every day.”
From herpes to hidden mould, experts say it’s time to ditch the communal lip balm habit.
“Lip balm is personal,” Danielle concludes. “Keep yours to yourself — and keep your lips healthy.”
