By Thom Watson, founder of Phatstix. After nearly two decades in beauty and more drawer-filling balms than I care to count, I started making my own. This is what I actually learned about what's in these things.
The short answer: no, most lip balm is not bad for you. The ingredients in the majority of products (beeswax, plant butters, oils) are safe and well-tolerated. But some cheaper formulas contain menthol, fragrance, or certain preservatives that can irritate lips and create a cycle where you need more balm to feel comfortable. It's not addiction, it's irritation. Here's how to tell the difference.
Is there any evidence that lip balm is actually harmful?
No good evidence suggests that lip balm, as a category, is harmful. The Cleveland Clinic notes that most lip balms are safe, and that the idea of "lip balm addiction" is largely a myth. Your lips cannot become physically dependent on balm the way they might on a medication.
That said, "lip balm" covers an enormous range of formulations. A 100% natural beeswax stick and a mentholated petroleum-jelly gel share a name but not much else. The question isn't whether lip balm is bad for you, it's whether the specific ingredients in your balm are working for or against your lips.
What ingredients can cause problems?
A handful of ingredients appear in cheaper or mass-market balms that may do more harm than good for some people. None of them are toxic in the clinical sense, but they can set up a frustrating loop.
Menthol and camphor are the main culprits. They produce a cooling sensation that feels soothing, but they're actually mild irritants. For some people, particularly those with eczema-prone or reactive lips, repeated exposure triggers light inflammation, which means the lips feel dry and uncomfortable again almost immediately after application. You use more balm. The cycle continues. The Cleveland Clinic specifically lists menthol and camphor among ingredients to be cautious about if you find your lips constantly needing more balm.
Fragrance and flavour are common sensitisers. Strawberry, vanilla, mint, citrus: they smell and taste appealing, but fragrance molecules are one of the most common causes of contact sensitisation on lips. If your lip balm stings or your lips feel worse over time rather than better, fragrance is the first thing to question.
Salicylic acid appears in some "exfoliating" or medicated balms. It strips surface skin cells, which can leave lips feeling smoother briefly but may increase sensitivity with regular use.
Lanolin is a waxy animal-derived ingredient with good conditioning properties, but it's also a known contact allergen for some people. If you have a lanolin sensitivity you will know about it.
None of these ingredients are dangerous at the concentrations used in cosmetics. They're just not doing your lips any favours if your lips are already unhappy.
What about petroleum-based balms? Is petroleum jelly bad for lips?
Petroleum jelly (petrolatum, Vaseline) is one of the most thoroughly safety-tested cosmetic ingredients in existence. It is not harmful. What it does is create an occlusive seal on the lip surface that prevents moisture loss, but it doesn't add anything to the skin itself. It's a lock on an empty room.
If your lips are already well-conditioned, petroleum jelly maintains that. If they're already dry and compromised, it holds the status quo without addressing the underlying dryness. It's not bad, it's just not doing much. For most people, a balm built around conditioning butters and oils will give more meaningful improvement.
Can lip balm make your lips more dependent on it?
Not in any pharmacological sense. The idea of "lip balm addiction" gets a lot of attention but it isn't supported by the science. Your lips don't develop chemical dependency on beeswax or shea butter.
What can happen is an irritant cycle. If a balm contains an ingredient your lips react to (menthol, fragrance, a particular preservative) your lips may feel consistently dry or tight after the product wears off. You apply more. Repeat. The sensation of needing constant balm isn't your lips "craving" it, it's low-grade irritation from something in the formula.
The fix is straightforward: switch to a balm without the irritating ingredient and see if the constant-reapplication urge disappears. For most people, it does.
Are there ingredients that definitely are fine?
Yes. A long list of ingredients have an excellent safety record and are genuinely beneficial for lip condition.
Beeswax (Cera Alba) forms a protective, breathable seal. It's been used in lip care for centuries and has an outstanding safety profile.
Shea butter, cocoa butter and mango butter are rich emollients that condition and nourish the lip surface. They're well-studied and well-tolerated.
Jojoba oil is technically a liquid wax with an excellent safety record and good skin compatibility.
Plant oils generally (sunflower, sweet almond, grapeseed) are nourishing and very unlikely to cause irritation.
None of these are glamorous. They're just things that work without causing problems. The Balm, Phatstix's 30g formula, uses exactly these: shea, mango and cocoa butter with jojoba and a handful of other plant oils. No fragrance, no flavour, no petrochemicals. Not because petrochemicals are evil, but because they're not needed.
Should you worry about parabens in lip balm?
Parabens (methylparaben, ethylparaben and similar) are preservatives used in many cosmetics to prevent microbial growth. They've been the subject of considerable alarm, some of it proportionate and some of it not.
The current regulatory position in the UK and EU is that parabens in cosmetics at permitted concentrations are safe. The European Chemicals Agency and UK's Office for Product Safety and Standards have reviewed the evidence. The widespread scare around parabens and hormonal disruption is based on studies using concentrations far higher than those found in cosmetics.
If you'd rather avoid them, that's a reasonable personal preference and there are plenty of paraben-free products. But "paraben-free" as a marketing claim often does more to frighten than to inform.
What about lip balms with SPF? Are those safe?
Sun-protection lip balms are a legitimate product category. The active ingredients used in them (usually chemical UV filters or mineral zinc oxide/titanium dioxide) are the same ones approved for use in facial sunscreens and are well-studied.
One thing worth clearing up: raspberry seed oil does not provide meaningful SPF protection. A study in the early 2000s suggested it might; subsequent research has not supported this, and no cosmetics regulator recognises it as a sun-protection ingredient. Any balm implying SPF from a plant oil alone is overstating the evidence considerably.
If you want genuine sun protection on your lips, look for a product with a stated, tested SPF number, not a "natural SPF" claim from an oil.
(Note: Phatstix The Balm contains no SPF. It is a conditioning balm, not a sun-protection product. If you're out in strong sun, use an SPF lip product for that purpose.)
Is there anything in lip balm I should actually avoid?
Here's a practical shortlist, drawn from dermatology sources including the Cleveland Clinic's guidance on lip balm ingredients to watch:
Worth being cautious about if your lips are reactive or consistently uncomfortable:
- Menthol and camphor (can create an irritant cycle)
- Fragrance and flavour (common contact sensitisers)
- Salicylic acid (may increase sensitivity with regular use)
- Lanolin (if you have a known lanolin sensitivity)
Fine for most people:
- Beeswax
- Plant butters (shea, cocoa, mango)
- Plant oils (jojoba, sunflower, sweet almond)
- Petrolatum / petroleum jelly (safe, just occlusive rather than conditioning)
- Parabens at permitted concentrations
This isn't a terrifying list. The ingredients to avoid are mostly there to check if you're experiencing unexplained irritation or that constant-reapplication feeling, not to cause alarm about lip care generally.
So what makes a good lip balm?
A few straightforward things. Ingredients that condition the lip surface (butters, oils) rather than just seal it. No fragrance or flavour if your lips are prone to irritation. A formula you can actually read and understand.
Size and value matter too. A 30g balm used consistently for a year will do more for your lips than a 4g tube you lose in a week and replace three times. Our formula is 30g, roughly 7 times the size of a standard balm, so you can actually build a proper routine with it rather than constantly hunting for the thing. No fragrance, no flavour, 100% natural. Not because that's a marketing position, but because it's what actually works.

FAQ
Is lip balm really addictive?
No. There is no pharmacological mechanism by which lip balm ingredients cause dependency. What some people experience is an irritant cycle: a balm containing menthol or fragrance causes low-grade irritation, the lips feel uncomfortable after it wears off, and more balm is applied. Switching to a fragrance-free, menthol-free formula usually resolves the sensation. The Cleveland Clinic confirms there's no true addiction involved.
Is high-street lip balm bad for you?
High-street lip balms are not dangerous. Some formulations include menthol and fragrance, which can cause irritation in people with reactive lips. The base formula (petroleum jelly, wax, oils) is safe. If you find you're constantly reapplying, check whether menthol or fragrance is in the ingredients list.
Can lip balm irritate your lips?
Yes, certain ingredients can. Menthol, camphor, fragrance, flavour and salicylic acid are the most common causes of lip-balm-related irritation. If your lips feel worse or more dependent over time, switch to a simple, fragrance-free formula without cooling agents and see if the irritation settles.
Is it bad to use lip balm every day?
No, daily use of a simple, fragrance-free balm is fine. If anything, regular application of a conditioning formula helps maintain the lip surface. The issue is not frequency of use but the specific ingredients in the product.
Does lip balm expire?
Yes. Most lip balms carry a PAO (period after opening) symbol, typically 12 months. After that, the oils can go rancid and the preservative system may be less effective. A product you've had for two years at the back of a drawer is probably worth replacing.
Is natural lip balm better?
"Natural" doesn't automatically mean safer or more effective, poison ivy is natural. What matters is whether the specific ingredients are well-tolerated and doing a useful job. Plant butters and oils have an excellent safety record and genuinely condition lips, which makes them a sensible basis for a balm. Fragrance-free and flavour-free is generally the better choice if your lips are eczema-prone, whether the formula is "natural" or not.
