How much lip balm do you swallow in a year?

At most about 1 to 2 tubes for a typical user and 5 for a heavy one, and only if every bit you apply is swallowed. The "4 tubes" claim checked against EU figures.

For most people, less than the "4 tubes a year" you may have read, and the safest way to put it is as a ceiling. If every bit of balm you put on your lips ended up swallowed, a typical user would swallow about 1 to 2 standard tubes a year, and a heavy user about 5. Those figures come from how much lip product people actually apply. The EU's safety assessors use 0.057 g a day for lipstick and lip balm, which is a heavy user's figure: it works out at 20.8 g a year, or about 4.9 tubes of 4.25 g. A US weighing study found the average woman used 24 mg a day, which is about 2.1 tubes a year, and half used 13 mg or less. But not all of what you apply is swallowed, because some comes off on cups, food and napkins, and no study we found has measured how much. So the true amount is lower than these ceilings, by a share that nobody has yet pinned down in a published study.

• EU figure: 0.057 g a day
• That is 20.8 g a year, about 4.9 tubes
• US average: 24 mg a day, about 2.1 tubes
• US median: 13 mg a day, about 1.1 tubes
• Swallowed share: not measured

What "swallowing lip balm" means here

Lip balm sits on the edge of your mouth, and through the day some of it leaves the lips. You lick it off, it goes in with food and drink, or it rubs off on a cup, a fork or a napkin. In this article, "swallowed" means the part that ends up in your stomach, which safety assessors call oral exposure, or ingestion.

That is a different number from the amount you apply. Every gram you swallow was applied first, but not every gram you apply is swallowed, so the amount applied is a ceiling on the amount swallowed. That one idea settles most of the confusion on this subject, and it runs through everything below.

The studies in this article measured application, and nobody weighed what went down. That is why the answer above is a ceiling and not a single number.

Three more terms come up below, all about how use is spread across people. A percentile ranks people from lowest to highest use, and the 90th percentile is the level that nine in ten people stay below. The median is the middle person, with half using less and half using more. The mean, or average, is the total divided by the number of people, and a few very heavy users pull the mean above the median.

Where the "4 tubes a year" figure comes from

One published version of the claim comes from Hong Kong's Consumer Council. In a short "trivia" item posted in February 2021, it wrote: "Studies have found that if you apply lip balm twice a day, you may have ingested about 4 tubes of lip balm each year."

The item does not name the studies, and it gives no tube size and no amount per application. The rest of the piece is about something else: mineral oil hydrocarbons in lip balm, and why the council thinks buyers should avoid them. The tube figure is the hook for that warning, not the subject of it.

So "4 tubes" is a claim without a stated method. That does not make it wrong, but it means the only way to judge it is to work out what it implies, and set that against figures that do have a method.

The EU figure: 0.057 g a day

The Scientific Committee on Consumer Safety, or SCCS, advises the European Commission on cosmetic safety, and its Notes of Guidance tell safety assessors how to do the sums. The current text is the 12th revision, which was adopted in May 2023 and corrected in December 2023.

Table 3A of that guidance lists how much of each product people use. One row covers "Lipstick, lip salve" (lip salve is an older word for lip balm), and it gives:

• an estimated daily amount applied of 0.057 g, which is 57 mg;
• a relative amount of 0.90 mg for each kilogram of body weight a day;
• a retention factor of 1.00;
• a calculated daily exposure of 0.057 g.

The figure is not a guess: the SCCS took it from large surveys of real use, published by Hall and colleagues in 2007 and 2011. The first of those covered 44,100 households and 18,057 people in five European countries, who used their own products and recorded every use, including use outside the home.

The key point is which part of the spread the SCCS chose. It says that from those distributions "the P90 was chosen", and P90 is the 90th percentile. So 0.057 g is a heavy user's figure, and nine in ten users apply less than that each day. The guidance calls its point values "conservative", meaning they are set high on purpose so that the sums cover nearly everyone who uses the product.

A separate table, Table 3C, gives the lip area and how often, putting lipstick and lip salve at 4.83 cm2 of surface and 2 applications a day. Spread 0.057 g over two uses and you get 28.5 mg each time. Spread that over 4.83 cm2 and you get about 5.9 mg on each square centimetre of lip, each time, or about 11.8 mg per square centimetre over the day.

What the retention factor of 1.00 does and does not mean

This is where the "4 tubes" idea goes wrong most often. It is easy to read "retention 1.00" as "all of it is swallowed", but it does not mean that.

The SCCS explains the factor in a footnote to the same table, where it says the retention factor "was introduced by the SCCNFP to take into account rinsing off and dilution of finished products". The SCCNFP was the committee before the SCCS. Shower gel and shampoo get a factor of 0.01 in the same table, because nearly all of it goes down the drain, while body lotion, face cream and lip products get 1.00, because nobody washes them off. So 1.00 means the product stays on the skin, and it says nothing about the stomach.

The guidance deals with swallowing in a separate passage, on oral exposure, where it says products such as "toothpaste, mouthwash or lipstick are normally not intended to be ingested". So, it goes on, the oral retention factors "will normally be small". In other words, the SCCS itself expects only part of a lip product to be swallowed, though the table does not give a number for that part.

In practice, a cautious assessor can simply count the whole applied amount as swallowed. The US researchers in the next section did exactly that, and said so in their paper. This site's own BHT and synthetic antioxidants page and its nut oil allergy page both run their sums on the 0.057 g figure. That is a worst case, chosen so that a safe answer stays safe, and it is not a measurement of what anyone swallows.

The US weighing study: what average users apply

The SCCS table gives the heavy-user figure only, so for the middle of the range the clearest numbers come from a US study by Loretz and colleagues, published in 2005.

The team recruited 360 women aged 19 to 65, in ten places across the US. Each woman got test products and kept a diary of every use for two weeks, and the products were weighed at the start and at the end. So the result is a weighed amount, not a guess from a questionnaire. For lipstick, they reported:

• a mean of 10 mg per application, and a median of 5 mg;
• a mean of 24 mg a day, and a median of 13 mg;
• a mean of 2.35 applications a day.

A later paper by Liu, Hammond and Rojas-Cheatham, published in 2013, drew on the same study. It gives two more figures from it: use ranged from 0 to 20 times a day, and the 95th percentile was 87 mg a day. The Liu team then wrote: "We assumed that all applied lip products were ingested." That is the cautious route again, stated plainly in the methods of the paper.

Note what the median says: half the women in the study used 13 mg a day or less, which is less than a quarter of the EU figure, and the mean of 24 mg is under half of it.

The numbers side by side

Here is every figure above, turned into grams a year and standard tubes. A standard twist-up lip balm tube holds 0.15 oz, which is 4.25 g, and the sizes are set out on our lip balm price per gram page. The yearly figures are our own arithmetic: the daily amount times 365, then divided by 4.25 g for the tube count.

Read down the table and the "4 tubes" claim falls into place. It sits between the average user and the EU heavy user, much closer to the heavy end. It is about twice what the average US user applies, and more than three and a half times what the median user applies.

The US and EU figures do not line up exactly. The US 95th percentile is higher than the EU 90th, which is what you would expect from a higher cut-off, and the two studies used different methods, countries and products. But they agree on the shape: most people sit well below the heavy-user figure, and a few people apply a great deal.

A worked case: the "4 tubes" claim, walked through

Take the Hong Kong claim at face value and follow it back to a daily amount. Nobody in this section tested anything: it is the published figures, worked through.

1. Four tubes a year, per day. At 4.25 g a tube, four tubes is 17.0 g, and 17.0 g over 365 days is about 46.6 mg a day.
2. Per application. The claim says twice a day, so each use would be about 23 mg.
3. Against the US study. The average woman used 10 mg per application and 24 mg a day, so the claim needs a person who puts on more than twice the average amount each time.
4. Against the EU figure. The SCCS heavy user applies 28.5 mg twice a day, and the claim's 23 mg is a little below that, so the claim describes a heavy user.
5. Applied or swallowed? Even for that heavy user, 17 g is what goes on the lips over the year. The SCCS says the swallowed share of a lip product will "normally be small", so 17 g swallowed would need every milligram to go down, which no source supports.

Walked through like that, the claim is not absurd: it is a fair guess at what a heavy user applies. It just gets two things wrong, because it presents a heavy user as everyone, and it presents the amount applied as the amount eaten.

Work out your own figure

You do not need anyone's average, because you can find your own ceiling for a year with no scales at all.

1. Count your tubes. Think back over the last twelve months. How many lip balms did you finish, or nearly finish? Leave out the ones you lost, since a lost tube was never applied to your lips.
2. Check the size. Look at the weight on the label, where most standard sticks are 4 to 4.25 g. A fat round tube is often about 5.5 to 6 g, and a small tin about 4 to 9 g.
3. Multiply. Tubes times grams gives the most you could have swallowed in the year you counted.
4. Turn it into a daily figure, if you want one. Divide the grams by 365, then multiply by 1,000 for milligrams.

If your tube lasts three months, you are near the heavy end, and if it lasts six months or more, you are near the middle. Our page on how much balm to apply has a table showing how long a 4.25 g tube lasts at different habits, and it reads well alongside this one.

If you finish a tube in two or three weeks, the issue is probably not swallowing. Very frequent use often means the balm is not holding, or that licking is drying your lips, a loop that is set out in does lip balm dry your lips.

What this means for the ingredients

The yearly gram figure sounds large, but what matters for safety is how much of each ingredient that carries, set against a level known to be safe. This is how safety assessors use the 0.057 g figure. The full method is on our page about safety assessment and the CPSR.

The quick rule is that every 1 percent of an ingredient in the balm adds 0.57 mg a day for a heavy user, and 0.24 mg a day for an average US user. Over a year, it looks like this.

Two pages on this site run this sum for real ingredients. The synthetic antioxidants page takes BHT at 0.02 percent in a lip balm, and at 0.057 g a day that is 0.0114 mg of BHT, about 0.07 percent of its acceptable daily intake for a 70 kg adult. The nut oil allergy page takes a balm with 30 percent almond oil, and even for a cold pressed oil it puts the daily protein at about 1/120 of the reference dose used for peanut. Both sums treat the whole 0.057 g as swallowed, so the real figures are lower still.

Body weight changes the picture for small people, because the same balm in a child gives a larger dose per kilogram. And children often chew the stick itself, which no usage study covers. Our page on lip balm for children starts from the assumption that the whole stick may be eaten, which is the right assumption for a toddler and a different question from this one.

Is swallowing lip balm harmful?

The amount is small by the standards safety assessors work with, which is the point of the table above. Lip products, like toothpaste and mouthwash, are cosmetics where some swallowing is expected. The EU sums are built to allow for it. What matters is the ingredient list, not the yearly gram count.

The Consumer Council's concern was mineral oil, but highly refined petrolatum and mineral oil are a different thing from the untreated oils behind the cancer classification, as our page is petroleum jelly bad for you explains. The grades and their names are set out in petrolatum and mineral oil. If you want to avoid them anyway, that is a fair choice, and the label tells you which products to skip.

Some ingredients do deserve a second look if you lick your lips a lot or apply balm often. Camphor, menthol and phenol are there for a cooling feel, and they have real limits, set out in menthol and camphor safety limits. Flavours and sweeteners invite licking, which raises the share you swallow, as explained in lip balm flavour and sweeteners. SPF lip balms carry sunscreen filters, which are covered in lip balm with SPF. To find any of these on a pack, use reading a balm label.

A whole tube swallowed at once is a very different matter from a slow trickle over a year, and it happens with small children and with dogs. For a dog, our page my dog ate a lip balm works through a whole tube, ingredient by ingredient. For a child who has eaten a stick with camphor, menthol or essential oils in it, call a poison line or a doctor straight away.

Why the "4 tubes" claim persists

It survives because it is close enough to sound right. A heavy user really can apply about four tubes' worth in a year, and someone who finishes a tube every three months can check that for themselves, so the number does not feel made up.

What gets lost is the step from "applied" to "swallowed". A claim about what you eat is more striking than a claim about what you use, and a figure for a heavy user is easy to repeat as a figure for everyone. The safety tables help that slip along, because they show the heavy-user figure and a retention factor of 1.00, and both are easy to misread. The first is a 90th percentile, and the second means the product is not rinsed off. Neither one says that an ordinary user swallows four tubes.

The fair version is shorter and less dramatic. A typical user applies 1 to 2 tubes a year, a heavy user applies about 5, and some unknown part of that is swallowed.

Quick reference

What this answer does not cover

Every figure here is an amount applied, and none is an amount swallowed. We found no study that measured what share of a lip balm ends up in the stomach, so the real figure is lower than every row in the tables by an amount we cannot state.

The usage data come from lipstick and from adults. The US study weighed lipstick used by women aged 19 to 65, and the EU figure covers "lipstick, lip salve" together, from surveys in five countries. Clear lip balm may be applied more often, or in thicker layers, than coloured lipstick. Men, teenagers and children are not in the US study at all, so if your habits are unusual, count your own tubes instead of using ours.

This page does not judge whether any one ingredient is safe to swallow, which depends on the ingredient, its amount, and a safe-intake figure for it. Use the 1 percent table to get the dose, then check the ingredient's own page. And a whole tube eaten at once by a small child or a pet is a poisoning question, not a yearly-intake question.
