Most lip balms are some mix of three things: an occlusive that seals (often beeswax or petrolatum), emollients that soften (plant oils and butters), and "extras" like fragrance, flavour, menthol or SPF filters. The seal-and-soften part is what looks after your lips. The extras are where a lot of the trouble starts, and where you actually need to read the label.
That's the short version. The longer version is more useful, because "read the label" only helps if you know what you're reading. Below is a plain-English tour of what goes into a lip balm, what each bit is doing, which ingredients are worth seeking out, and which ones are worth a second look before you buy. No scaremongering, no sermon, just the actual chemistry, with sources you can check.
A quick disclaimer before we start, because this is the internet and lips are skin: this is general information, not medical advice. If your lips are cracked, bleeding, won't recover, or you think you're reacting to something, see a pharmacist or GP. They'll sort you out faster than a blog post will.
What is lip balm actually made of?
Almost every lip balm is built from the same three jobs, in different proportions. One ingredient seals moisture in (the occlusive), one or two soften and condition (emollients), and the rest is optional extras (colour, flavour, fragrance, actives, preservatives).
The occlusive is the backbone. It's usually beeswax, a plant wax (like candelilla or carnauba), or petrolatum, and its job is to form a thin barrier that slows water escaping from the skin. Dermatologists call that water escape transepidermal water loss, and reducing it is genuinely how a balm "holds" moisture (Cleveland Clinic).
The emollients are the oils and butters, things like shea, cocoa, jojoba, sunflower and coconut. They sit between the cells in the top layer of skin, filling the gaps and making the surface feel smooth and supple. Together, a wax plus good oils is most of a proper balm. Everything after that is a choice. The trick is knowing which of those choices help and which are just there to make the product smell of cake.
What are the good ingredients in lip balm?
The ingredients worth looking for are simple: a natural occlusive wax, nourishing plant butters, and conditioning oils. They're the boring, effective core that does the actual caring, and a balm made mostly of these will look after your lips without needing a marketing department.
Here are the ones that earn their place:
- Beeswax (Cera Alba). A natural occlusive that forms a protective, breathable barrier and reduces water loss. It's been used on skin for centuries, and a 2023 review of beeswax in skincare found it supports the skin barrier and has soothing properties (Nong Y et al., "A review of the use of beeswax in skincare", Journal of Cosmetic Dermatology 2023;22:2166–2173, doi:10.1111/jocd.15718). Worth knowing: beeswax is the reason most natural balms (ours included) are not vegan.
- Shea butter. A rich emollient that softens and conditions. Reviews of its skin benefits point to its fatty-acid profile filling the spaces between skin cells (Lin et al., 2017).
- Cocoa and mango butter. More emollient butters in the same family, each with a slightly different feel and melt. (We compare the three in detail in our guide to shea, cocoa and mango butter for dry lips.)
- Jojoba oil. Technically a liquid wax that's close to skin's own sebum, which is why it sits so comfortably. It has documented soothing properties (Pazyar et al., 2013).
- Plant oils. Sunflower, sweet almond, grapeseed and raspberry seed are lightweight emollients that round out the texture.
None of these are exotic. That's the point. The best lip balm ingredients are the ones you can pronounce.
What lip balm ingredients should you avoid (or at least question)?
The ingredients worth a second look aren't "toxic", they're just ones that can irritate some lips or set up a use-it-more cycle. The big names are fragrance, flavour, menthol, camphor, phenol, certain acids, and some preservatives. None of these are dangerous in a properly assessed cosmetic. The question is whether they belong on lips that are already sore.
Here's the honest breakdown.
Fragrance and flavour
Added fragrance ("Parfum") and flavour are among the more common causes of contact reactions in skincare. The American Academy of Dermatology specifically tells people with eczema-prone or chapped lips to avoid fragrance and flavouring when choosing a balm (AAD). It's not that fragrance is bad for everyone, it's that a sore, broken lip surface is exactly where a reaction is most likely to show up. If your lips are fine with a vanilla balm, carry on. If they sting, the smell is a suspect.
Menthol, camphor and phenol
These are the tingly ones, the "cooling" or "medicated" feel in some classic balms. That tingle is a mild irritant effect, and dermatologists routinely list menthol, camphor and phenol among the ingredients that can dry or irritate lips and are best avoided if yours are already cracked (Cleveland Clinic). They feel like they're doing something. Sometimes what they're doing is keeping you reaching for the tube.
Salicylic acid and other exfoliating acids
Some "medicated" lip products contain salicylic acid to slough off flaky skin. On already-damaged lips that can make dryness worse, which is why it shows up on dermatology "avoid if chapped" lists (Cleveland Clinic).
A note on petrolatum (petroleum jelly)
Petrolatum is a genuinely effective occlusive and it is not unsafe in cosmetics. It's a fair sealer. What it doesn't do is condition the way oils and butters do, because it sits on top rather than softening the skin itself. That's a "what does it do" point, not a "good vs evil" one, and we go through it properly in lip balm vs Vaseline.
We'll be blunt about the limit of our knowledge here: "irritant for some people" is not the same as "bad for you". For the full myth-versus-reality on safety, see is lip balm bad for you, and for the deep-dive on each ingredient, the ingredients that keep your lips dry.
Good vs questionable lip balm ingredients: a quick table
Here's the whole thing on one screen. "Questionable" means worth a second look, especially if your lips are already chapped. It does not mean unsafe.
| Ingredient | What it does | Verdict | Why |
|---|---|---|---|
| Beeswax (Cera Alba) | Occlusive, seals in moisture | Seek out | Breathable barrier, supports skin barrier (Nong et al. 2023, doi:10.1111/jocd.15718) |
| Shea / cocoa / mango butter | Emollient, softens | Seek out | Conditions and smooths the skin surface (source) |
| Jojoba oil | Emollient, close to skin's own oil | Seek out | Comfortable, soothing (source) |
| Plant oils (sunflower, almond, grapeseed) | Lightweight emollients | Seek out | Round out texture, low irritancy |
| Petrolatum | Occlusive, seals only | It depends | Effective sealer, but doesn't condition like oils |
| Added fragrance / flavour | Smell and taste | Question it | Common irritant on chapped lips (AAD) |
| Menthol / camphor / phenol | "Cooling" tingle | Question it | Mild irritants, can worsen dryness (source) |
| Salicylic acid | Exfoliates flaky skin | Question it | Can dry already-damaged lips |
If you remember one row, make it the bottom three: the things to question are the smell, the tingle, and the acid.
How do you read a lip balm ingredients list?
Ingredients are listed in order of how much there is, most first, down to the smallest amounts at the end (anything under 1% can be in any order). So the first three or four ingredients tell you what the balm actually is. The bottom of the list is where fragrance, preservatives and colour usually hide.
A few quick rules that make a label readable in ten seconds:
- Read the top of the list first. If a wax and recognisable oils are at the top, it's a real balm. If you can't tell what the first ingredient is, that's worth a pause.
- Scan the bottom for "Parfum", "Aroma" or "Flavour". That's where fragrance lives.
- Names are in Latin (INCI) by law. "Butyrospermum Parkii" is shea butter, "Cera Alba" is beeswax, "Simmondsia Chinensis" is jojoba. It looks intimidating, it's just standardised naming.
- "Fragrance-free" and "unscented" can mean different things. Unscented sometimes means a masking fragrance was added to hide a smell. Fragrance-free should mean none was added at all. (More on why we left the vanilla out in unscented vs flavoured lip balm.)
- A short list isn't automatically better, but it's easier to vet. Fewer ingredients means fewer things that can go wrong, and less to hide.
For reference, here's what our hero product, The Balm, is made of, top to bottom: beeswax, sunflower oil, jojoba oil, sweet almond oil, grapeseed oil, raspberry seed oil, shea butter, cocoa butter, mango butter. Nine things. No water, no fragrance, no flavour, no preservatives. We made The Balm 100% natural because, for an unscented lip balm, we could. (Our tinted balms add a small amount of cosmetic-grade colour pigment, so they're not 100% natural and we don't pretend otherwise.)
Is "natural" lip balm actually better?
"Natural" tells you where ingredients came from, not whether they work or whether they're safe. Plenty of effective ingredients are natural (beeswax, shea), plenty are synthetic and perfectly fine, and "natural" isn't a regulated word, so it can mean almost anything on a label. Treat it as a starting point, not a guarantee.
This is where a lot of lip balm marketing goes off the rails, so let's be precise. There's an actual international standard for measuring how natural a cosmetic is, ISO 16128, which calculates a "natural origin index" from how ingredients are sourced and processed (ISO 16128). When a brand throws around "natural" with no number and no standard behind it, that's a vibe, not a fact.
A few honest truths worth holding onto:
- "Natural" doesn't mean "won't irritate". Essential oils and natural fragrances are natural and are common irritants.
- Synthetic doesn't mean "harmful". A lab-made ingredient can be purer and more consistent than a mined or extracted one.
- "Natural" is not the same as "certified". Certification is about farming and standards, and we don't claim it, because we aren't certified.
If you want the full breakdown of what the word should and shouldn't mean, we wrote a whole piece on what "natural" should mean on a lip balm in the UK. The short version: ask for the number, ask for the standard, and be suspicious of the word on its own.
Why do some lip balms make your lips feel drier?
A balm can leave lips feeling worse for two reasons: an irritant ingredient setting up a reaction, or a habit loop where you apply, the surface feels smooth, it wears off, and you apply again without the underlying skin ever recovering. It usually isn't the balm "drying you out" chemically. It's irritation plus repetition.
The irritant side is the menthol, camphor and fragrance story above. The habit side is more interesting and more common: if a balm only sits on the surface and doesn't actually condition, or if a tingly ingredient keeps prompting you, you can end up in a constant reapply cycle. People call this lip balm addiction, and while your lips aren't chemically "hooked", the loop is real. We unpicked the whole myth in is lip balm addiction real.
The fix isn't to stop using balm. It's to use one with conditioning emollients and no irritants, so the lip surface gets a chance to settle rather than just being topped up. A balm that softens as well as seals breaks the loop because your lips genuinely improve underneath.
What about SPF, "clear" balms and tinted balms?
SPF in a lip balm is a real, useful thing, but only if the product is properly tested and labelled with an SPF number. Tint comes from added pigment, and a "clear" balm is just one with no colour added. None of these change the seal-and-soften basics, they're additions on top of them.
Three quick honest notes:
- SPF. If you want sun protection on your lips, you need a balm that actually carries an SPF rating, applied properly and often. Don't assume a balm protects you just because it's greasy or because an oil "sounds protective". (For the record, none of our balms contain SPF, so we'd never imply otherwise.) Some natural oils get hyped as "natural SPF" online, raspberry seed oil especially. The evidence for that is weak and we wouldn't rely on it.
- Tint. A tinted balm is a normal balm with cosmetic colourant added (usually iron oxides and/or organic pigments). The colour is the bit that makes it not 100% natural, which is exactly why we keep that claim to The Balm and frame our tints honestly as natural-origin (final percentage pending our supplier figures).
- "Clear". Nothing clever, just no colour. The base does the work.
What's in The Balm, and why we kept it simple
I'll be straight with you, because that's the whole brand. The Balm is nine natural ingredients: beeswax, five plant oils, and three butters. No water, no fragrance, no flavour, no preservatives, no petrochemicals. It's non-comedogenic and suitable for all skin types, and the oil blend (sunflower oil in particular) is shown to support the skin's barrier and skin renewal (Lin et al., 2017). It's a 30g stick, roughly 7x the size of a standard 4.25g lip balm (7.06x, if you want the exact figure), and it's designed to last up to a year.
I didn't set out to make a "natural beauty" product. I made this because I've got eczema-prone skin and a drawer full of balms that were either lovely-but-gone-in-a-week or waxy, and all of them overpriced. After about 15 goes in my kitchen, and then a year with a lab in Yorkshire, this is what worked: a wax to seal, good oils and butters to condition, and nothing in it that didn't need to be there.
"I'm not here to make grand promises or sell you a lifestyle. It's a big, buttery stick for lips, faces and flaky places. No fluff. Just proper care."
The reason it's unscented is the reason for half this article: fragrance is the bit most likely to bother an already-sore lip, so I left it out. The reason it's so big is that I never understood why we accept face moisturiser in a 50ml jar but lip balm in a 4g tube. Same skin. Bigger version. That's it.
If you've read this far, you already know how to vet a balm. Read the top of the list, question the smell and the tingle, and ask what "natural" actually means. If you'd rather skip the homework, our 30g balm is the version of that advice I'd hand to a friend.
FAQ
What is the main ingredient in lip balm?
The main ingredient is usually a wax that acts as an occlusive, sealing moisture into the lips. Beeswax (Cera Alba) is the most common natural one; petrolatum and plant waxes like candelilla are alternatives. After the wax come emollient oils and butters that soften and condition the skin.
What lip balm ingredients should I avoid?
There's no ingredient everyone must avoid, but if your lips are chapped or eczema-prone, dermatologists suggest steering clear of added fragrance, flavour, menthol, camphor, phenol and salicylic acid, as these can irritate already-damaged lips (AAD; Cleveland Clinic). They're not unsafe, just more likely to cause a reaction on sore lips.
Is natural lip balm better than regular lip balm?
Not automatically. "Natural" describes where ingredients come from, not how well they work or how safe they are, and it isn't a regulated term. Some natural ingredients (like essential oils) can irritate, and some synthetic ones are perfectly fine. Look for a balm with conditioning oils, a sealing wax and no irritants, natural or not.
Why does lip balm make my lips drier?
Usually it's one of two things: an irritant ingredient causing a low-level reaction, or a habit loop where a balm that only sits on the surface keeps wearing off, so you reapply constantly without the skin recovering. A conditioning balm without fragrance or menthol tends to break that cycle.
How do I read a lip balm ingredients list?
Ingredients are listed by quantity, most first. Read the top few to see what the balm really is (look for a wax and recognisable oils), then scan the bottom for "Parfum", "Aroma" or "Flavour", where fragrance hides. Names are in standardised Latin (INCI), so "Butyrospermum Parkii" is shea butter and "Cera Alba" is beeswax.
Is lip balm with SPF worth it?
Yes, if it carries a proper SPF rating and you apply it often enough, since lips burn too. But a balm only protects you if it's actually tested and labelled with an SPF number. Don't assume a balm offers sun protection just because it's oily or "natural". (None of our balms contain SPF.)
