Why Your Lips Get Drier the More Product You Use

If you are reapplying lip balm every half hour, something is wrong, and it is probably the balm.

 

Lips are the part of your face people are least likely to understand and most likely to get stuck in a loop with. Here is why they dry out faster than anywhere else, what keeps the cycle running, and how to break it.

Why lips dry out faster than the rest of your face

The red part of your lip, properly called the vermilion, is genuinely different skin.

Its outer layer is far thinner than the skin around it, which is why it looks pink. You are partly seeing the blood supply through it. Thin means water leaves it much faster than it leaves your cheeks.

More importantly, the vermilion has almost no sebaceous glands. Everywhere else on your face, oil glands produce sebum that helps slow water loss. Your lips are essentially working without that. There is no self-generated protection, which is why they respond so quickly to cold, wind, dry indoor air and dehydration.

They also have very little melanin, which becomes relevant further down.

So lips are not simply dry skin in a smaller area. They are structurally short of the two things skin normally uses to look after itself.

The reason you keep reapplying

Two things drive the cycle, and neither is the one usually blamed.

Irritant ingredients. Menthol, camphor, phenol, salicylic acid and flavouring compounds are common in lip products. They produce that cooling, tingling sensation, which people read as the product working. It is closer to a low-grade irritant response. Repeated often enough it causes peeling, which prompts more balm, which causes more peeling.

Lip licking. This is the bigger one and it barely gets mentioned. Saliva feels soothing for about ten seconds, then evaporates and takes moisture from the lip surface with it. Saliva also contains digestive enzymes, which are not designed to sit on skin. Do it enough and you get a recognised condition called lip lick dermatitis, often with a visible red ring extending slightly beyond the lip line. Children get it constantly in winter and so do adults who are concentrating.

Plain occlusive balm does not cause dependency. That myth is persistent and it is not what is happening. The cycle comes from irritants and from licking.

The cooling tingle, including in mine

I need to be straight with you here rather than write around it.

My Mint Cocoa lip balm is scented with peppermint essential oil, which is high in menthol. It is a lovely balm and most people get on with it perfectly well, but everything I just wrote about cooling sensations applies to it too. Peppermint is also a reasonably common contact allergen in lip products specifically.

So if your lips are currently sore, peeling or reacting, do not use the mint one. Choose Cocoa Orange or Mango and Lime, which are gentler, or skip the flavoured range entirely for now and use something plain.

All three of my Lip Balms contain essential oils, because they are made to be pleasant as well as useful. For lips in genuine trouble, that is not what you want. The Barrier Repair Balm is the lowest essential oil product I make and works perfectly well on lips. That is what I would use on badly cracked lips, and I would rather send you there than to the prettier pot.

What actually breaks the cycle

1. Stop licking. Genuinely the highest impact change, and the hardest. Keep balm within reach so you have something else to reach for.
2. Switch to something unflavoured for a fortnight. No mint, no cinnamon, no fruit, no tingle. If your lips settle, you have your answer.
3. Apply properly at night. A thicker layer before bed, when you are not eating, drinking or talking it off, does more than a dozen daytime applications.
4. Look at your bedroom air. Central heating in winter is brutally dry, and lips show it first.
5. Check what else touches your mouth. Toothpaste is a common and overlooked culprit, particularly flavoured or whitening ones. So are mouthwash, chewing gum and, in some cases, nail varnish transferred by touching your face.

The lower lip and sun

This is the part of a lip balm article that usually gets left out, and clinically it is the most important thing on the page.

Your lower lip catches a great deal of UV simply because of the angle it sits at, and the vermilion has very little melanin to defend itself. Over years, that adds up. The lower lip is a genuinely common site for sun damage and for the precancerous changes that can follow it, and most people have never once thought about protecting it.

My lip balms have no SPF and are not tested for it, so please do not use them for that. If you spend a lot of time outdoors, walking, gardening, on the water or on a bike, use a lip product with a tested SPF and reapply it.

A persistent rough, scaly or white patch on the lower lip that does not settle, particularly if it has been there for weeks, is worth showing to a GP or dentist rather than treating with balm.

On the phrase chemical free

You will see this on lip products constantly and I want to be honest about it.

There is no such thing as chemical free. Water is a chemical. Beeswax is a chemical. Everything in my balms is a chemical, and so is everything in yours. UK cosmetic claims guidance actually treats the phrase as one that cannot be substantiated, which is a polite way of saying it is meaningless.

What people mean when they search for it is fair enough. They want fewer synthetic additives, shorter ingredient lists and no hidden fragrance. That is a reasonable thing to want and I have built a range around it. I am just not going to sell it to you using a phrase that falls apart the moment anyone thinks about it.

What is in mine

Shea butter (mango butter in the Mango and Lime), cocoa butter and beeswax give my balms their rich, protective texture, with coconut, sweet almond, avocado and jojoba oils to soften, and essential oils for scent. The tinted versions get their colour from mica and mineral pigments, which gives a buildable wash rather than the coverage of a lipstick.

Three scents. Mint Cocoa is peppermint with cocoa butter, and it is the one to avoid if your lips are reactive. Cocoa Orange is cocoa butter with sweet orange. Mango and Lime is mango butter with lime, and it is the lightest of the three in feel.

You can have each one plain, or with a sheer tint in blush, pink or red. The red is the most pigmented, and a few customers use it as a tinted balm rather than a lipstick.

There is no water in any of them, which is why they do not need a preservative. Without water, there is very little for bacteria or mould to grow in.

When it is not just dry lips

Some things look like chapping and are not.

Cracking and soreness at the corners of the mouth is often angular cheilitis, which can involve yeast or bacteria, and sometimes relates to iron or B vitamin deficiency. Balm will not resolve it. A pharmacist or GP will.

Persistent swelling, burning or a rash extending beyond the lip line can be allergic contact cheilitis, frequently from flavourings, toothpaste, or nickel from something you hold near your mouth. Patch testing identifies it properly.

A rough or white patch on the lower lip that does not clear should be looked at, as mentioned above.

Chronically dry lips can also be a straightforward sign of dehydration, of certain medications including isotretinoin, or of mouth breathing at night. Worth considering before you buy another balm.

Frequently asked questions

Why do my lips get drier the more balm I use?
Usually because of what is in the balm rather than the balm itself. Menthol, camphor, phenol, salicylic acid and flavourings cause a low-grade irritant response that leads to peeling and more reapplication. Lip licking does the same thing. Plain occlusive balm does not cause dependency.

Is lip balm addiction real?
Not in the sense of a physical dependency. What people experience is an irritation cycle driven by additives and by licking. Switch to something unflavoured for a fortnight and most people find the pattern breaks.

Why do lips dry out faster than the rest of my face?
The vermilion has a much thinner outer layer than surrounding skin and almost no sebaceous glands, so it cannot produce the oil that normally slows water loss. It also has very little melanin, which makes it more vulnerable to sun damage.

Should lip balm have SPF?
If you spend meaningful time outdoors, yes. The lower lip is a common site for sun damage and precancerous change, and it is almost always unprotected. My balms have no tested SPF, so use a dedicated SPF lip product for that.

Is peppermint bad for lips?
Not for everyone. Peppermint oil is high in menthol and is a recognised contact allergen in lip products, which are a leave-on product on skin with very little barrier. If your lips are sore, peeling or reactive, avoid it, including the mint version of mine.

Can I use lip balm if I have a nut allergy?
Always read the full ingredient list, since many balms use nut oils. Mine contain sweet almond oil, so please avoid them if you are allergic to almonds. They also contain shea butter, or mango butter in the Mango and Lime. Shea butter contains very little protein and reactions to it are rare, even among people with tree nut allergies, but if your allergy is severe, check with your GP or allergy specialist rather than relying on general advice. I list every ingredient and will answer any question about them.

Is chemical free lip balm a real thing?
No. Every substance is a chemical, including water and beeswax. The phrase cannot be substantiated under UK cosmetic claims guidance. What is achievable is a short ingredient list with no synthetic fragrance, which is a more useful thing to look for.

How long does a lip balm last?
Because there is no water in the formula, a little goes a long way and a pot lasts most people several months. Keep it out of direct heat, and if it ever smells sharp rather than of what it should, that is the oils oxidising and it is time for a new one.

The Lip Balms come in three scents, plain or tinted. If your lips are currently sore rather than just dry, start with the Barrier Repair Balm instead and come back to the pretty ones once things have settled.
