How to Heal Cracked, Sore Lips

Short answer: To heal cracked, sore lips, stop anything that irritates them (licking, peeling, tingly or flavoured balms) and keep them constantly covered with a plain occlusive such as petrolatum, shea butter or lanolin. Do not exfoliate broken skin. Most cracked lips settle within a week or two of gentle, consistent care, but painful cracks at the corners, bleeding that will not stop, or lips that do not improve after two to three weeks should be seen by a pharmacist or GP.

Why do lips crack and split in the first place?

Lip skin is thin, has almost no oil glands and cannot hold on to water the way the rest of your face can. When the protective barrier is stripped, moisture escapes, the surface dries out and eventually splits. Once there is an actual crack, the skin is broken, so it stings, catches when you smile and can bleed.

Common triggers include cold or windy weather, dry indoor heating, dehydration, mouth-breathing, sunburn, harsh or fragranced lip products, and the habit of licking or picking. Cracks that form specifically at the corners of the mouth can be a separate issue called angular cheilitis, which sometimes needs a pharmacist's help rather than balm alone.

What should you stop doing when lips are already cracked?

When lips are healing, what you avoid matters as much as what you apply. Broken skin is fragile, and most of the things that feel satisfying in the moment slow it down.

• Stop licking your lips. Saliva evaporates fast and takes surface moisture with it, and its digestive enzymes irritate already-raw skin.
• Stop peeling or biting flakes. Pulling loose skin off tears into living tissue underneath, which deepens the crack and invites infection.
• Stop exfoliating. A lip scrub is for healthy, flaky lips, not open cracks. Wait until the surface has healed before you scrub again.
• Stop using tingly or strongly flavoured balms. Menthol, camphor, peppermint and heavy fragrance sting and dry sore lips further.
• Stop matte and long-wear lipsticks for now. They are designed to dry down and will cling to and highlight every crack.

Think of this as a short recovery period. The less you interfere, the faster the barrier rebuilds itself.

How do you actually heal cracked lips, step by step?

Healing is mostly about protection and consistency. The aim is to keep the broken skin covered so it stays soft and can knit back together without drying out and re-splitting.

1. Clean gently. If lips are crusted or sore, press a warm, damp flannel against them for a minute to soften the surface. Do not rub or pick.
2. Apply a plain occlusive. A rich, fragrance-free balm with petrolatum, shea butter, lanolin or beeswax seals the skin and stops water escaping. This single step does most of the work.
3. Reapply often. Top up after eating, drinking and every couple of hours. Cracked lips need a barrier that is present, not one you applied once this morning.
4. Seal it overnight. Apply a generous layer before bed so lips repair undisturbed while you sleep, when skin does most of its recovery.
5. Protect from the trigger. Add SPF or a scarf outdoors in sun, cold or wind, and consider a bedroom humidifier if indoor air is dry.
6. Support from the inside. Drink enough water. Dehydration shows on lips quickly and slows healing.

A simple, fragrance-free Lip Balm is exactly what sore lips want during this phase: occlusives and emollients to seal and soften, without the tingle-for-the-sake-of-it ingredients that sting broken skin. Once lips have fully healed, you can bring a gentle Matcha Lip Scrub back into your routine to keep flakes at bay, but not before.

Which ingredients calm sore lips, and which make them worse?

On broken skin, plain and boring wins. Use this to check a product before you put it near a crack.

Shea and cocoa butter, beeswax	Heavy synthetic fragrance and strong flavours
Squalane and gentle plant oils (soften)	Exfoliating acids left on the lips
A short, fragrance-free ingredient list	Matte and long-wear lip colour

When should you see a pharmacist or GP about cracked lips?

Most cracked lips heal with a week or two of gentle care. Some do not, and that is when a professional should take a look. Speak to a pharmacist or GP if:

• Your lips do not improve after two to three weeks of consistent, gentle care.
• The cracks are at the corners of your mouth, sore, red or crusty (this can be angular cheilitis, which may need an antifungal or antibacterial cream).
• There is bleeding that will not settle, spreading redness, swelling, pus or signs of infection.
• You have painful blisters or tingling that could be a cold sore, which needs different treatment.
• Cracked, dry lips keep returning despite good care, which can occasionally point to an allergy, deficiency or medication side effect.

None of this is cause for alarm, but lips that stubbornly refuse to heal deserve a proper look rather than another new balm.

To heal cracked, sore lips, stop anything that irritates them (licking, peeling, tingly or flavoured balms) and keep them constantly covered with a plain occlusive…

Key takeaways

• Healing cracked lips is about calming and protecting them, not scrubbing or peeling.
• Stop licking, picking, exfoliating and using tingly or matte products while lips are broken.
• Keep lips constantly covered with a plain, fragrance-free occlusive and reapply often.
• Seal lips generously overnight, when skin repairs most.
• Most cracked lips settle within one to two weeks of gentle care.
• See a pharmacist or GP for corner cracks, persistent splits, bleeding or signs of infection.

Frequently asked questions

How long do cracked lips take to heal?

With consistent, gentle care most cracked lips settle within one to two weeks. If yours have not improved after two to three weeks, see a pharmacist or GP.

Should I exfoliate cracked lips to remove the flakes?

No. Exfoliating broken skin tears it further and slows healing. Wait until the cracks have closed and the surface is smooth again before using a lip scrub.

Why do my lips crack at the corners?

Cracks specifically at the corners can be angular cheilitis, often linked to moisture pooling there, and may need an antifungal or antibacterial cream. If they are sore, red or crusty and do not settle, ask a pharmacist.

Is Vaseline good for cracked lips?

Yes. Petrolatum is a strong occlusive that seals the skin and stops water escaping, which is exactly what broken lips need. A plain, fragrance-free balm does the same job.

Why do my lips crack more when I use lip balm?

The balm probably contains menthol, camphor, peppermint or fragrance, which irritate sore lips so they feel dry again quickly. Switch to a plain, fragrance-free occlusive balm.

Can I wear lipstick on cracked lips?

Skip matte and long-wear formulas while lips are broken, as they dry down and cling to cracks. Once healed, a conditioning tinted lip oil is a gentler way to add colour.
