Phatay Honth: Chapped Lips Routine and the Vitamin Deficiency Sign
Winter cracks lips, yes, but cracking that shows up in every season, or cracking specifically at the corners of the mouth that will not heal with balm, is a different problem with a different fix.
The short version
- Ordinary winter dryness: flaking, tightness, cracks across the lip surface, improves with balm and less licking
- Watch for: painful cracks specifically at the corners of the mouth, this is a distinct condition, angular cheilitis
- Common cause of that pattern: B-vitamin (especially B2 and B12) or iron deficiency, sometimes a fungal or bacterial component too
- Simple daily fix for dryness: plain petroleum jelly or ghee, applied before it cracks, not after

Our earlier guide on chapped lips home remedy with ghee and malai covers general dryness and moisturising well. This piece goes into the pattern that guide does not: cracking specifically at the mouth corners, and the deficiency link most people never connect it to.
Ordinary dryness versus something else
Plain winter chapping affects the whole lip surface fairly evenly, feels tight and flaky, and responds within a few days to regular moisturising and drinking enough water. It gets worse with excessive licking, since saliva evaporates and dries the lips further each time rather than moisturising them.
A different pattern, cracks specifically at the corners of the mouth, sometimes with redness, crusting, or a small split that reopens every time you open your mouth wide to eat or yawn, has a name: angular cheilitis. This is the pattern worth paying separate attention to, because moisturiser alone often does not fully clear it.
The B-vitamin and iron connection
Angular cheilitis is frequently linked to a deficiency in riboflavin (vitamin B2), vitamin B12, iron, or zinc. These nutrients support skin healing and the mucous membrane at the corner of the mouth specifically; when levels run low, that area is often one of the first places to show it, sometimes alongside a sore, smooth-looking tongue or unusual tiredness. A fungal infection (commonly candida) or bacterial infection often moves into the already-cracked skin afterward, which is part of why it can persist and resist plain lip balm.
See a doctor if corner-of-mouth cracking has lasted more than 2 weeks despite regular moisturising, if it is painful, bleeding, or crusted, if you also notice unusual fatigue, a sore or smooth tongue, or pale skin (possible signs of anaemia worth checking with a blood test), or if the cracking keeps recurring in the same spot every few weeks. A simple blood test can check B12, iron and general nutrition status, and a doctor can prescribe an antifungal or antibacterial cream if an infection has set in, which over-the-counter lip balm will not clear on its own. Diabetics with slow-healing mouth cracks should mention this specifically to their doctor, since blood sugar control affects healing.
A sensible daily routine for ordinary dryness
- Apply plain, unscented petroleum jelly or pure ghee to lips before bed every night, roughly a pea-sized amount, this is prevention, not just treatment after cracking starts.
- Reapply a thin layer of balm or ghee before going outdoors in cold, dry or windy weather, every time, not only when lips already feel dry.
- Drink at least 6 to 8 glasses of water through the day, dehydration shows up on lips faster than on most other skin.
- Avoid flavoured or menthol lip balms if lips are already cracked, the flavouring and cooling ingredients can sting and encourage more licking, which worsens dryness.
- Breathe through your nose where possible; habitual mouth breathing, especially overnight, dries lips faster than almost anything else.
Food sources worth including regularly
| Nutrient | Good food sources |
|---|---|
| Riboflavin (B2) | Milk, dahi, eggs, almonds, green leafy vegetables |
| Vitamin B12 | Eggs, dairy, meat, fortified cereals (limited in plant-only diets) |
| Iron | Red meat, lentils (masoor, chana), spinach, jaggery in moderation |
Food sources are a sensible daily habit for most people. If a blood test shows an actual deficiency, a doctor may recommend a specific supplement dose, which food alone will not correct quickly enough on its own.
Ghee and malai (fresh cream) applied to lips before bed is a genuinely old household habit across South Asia, valued for softening dry skin overnight, and it holds up well as a simple moisturising step even today. Traditional accounts do not typically connect chapped lips to nutrient deficiency specifically, that link comes from more recent nutrition science, and it is worth adding to the older moisturising habit rather than replacing it.
Sun and wind protection people forget about lips
Lips have thinner skin than the rest of the face and no oil glands of their own, which is exactly why they dry out faster than any other visible skin, and why they burn faster in strong sun too. A lip balm with SPF, or simply a layer of plain balm reapplied every couple of hours during a long day outdoors, especially at altitude or near water where reflected sunlight is stronger, prevents a surprising amount of ordinary chapping that people otherwise blame purely on cold weather.
A note on lipstick and matte formulas
Matte and long-wear lipstick formulas are drying by design, that is part of how they achieve the long-wear finish, and daily use without a moisturising step underneath can contribute to ongoing dryness that looks like a skincare mystery until the lipstick habit is considered. Applying a thin layer of plain balm as a base coat under lipstick, and giving lips a lipstick-free day once or twice a week, helps balance this out without giving up the lipstick entirely.
Try this
Once a week, before bed, gently rub a small amount of sugar mixed with a few drops of honey (skip honey for children under one year, and skip this scrub entirely for cracked or bleeding lips) over the lips in small circles for about 30 seconds, then rinse and apply balm. This removes flaking skin gently without the sharper edges of a store-bought lip scrub.
Myth check
Myth: licking dry lips helps moisturise them
It feels like it helps for a few seconds, then saliva evaporates and leaves lips drier than before, often creating a habit of near-constant licking that worsens the whole cycle.
Myth: all lip cracking is just weather
Weather explains most ordinary dryness. Persistent corner cracking that will not clear with regular moisturising deserves a look at nutrition and possibly a doctor’s opinion, not just a stronger balm.
Dentures and mouth corner cracking
Older adults wearing dentures, especially poorly fitting ones, are more prone to angular cheilitis because saliva pools at the corners of the mouth differently, keeping the area consistently damp and encouraging fungal growth there. If this describes your situation, a dental check on the denture fit itself is worth doing alongside any nutrition check, since correcting the fit often resolves cracking that supplements alone would not.
Why do only the corners of my mouth keep cracking?
This specific pattern, angular cheilitis, is often linked to B-vitamin or iron deficiency, sometimes with a fungal or bacterial infection in the crack itself. It usually needs more than lip balm to fully resolve.
Can chapped lips be a sign of a bigger health problem?
Occasional dryness in winter usually is not. Persistent cracking, especially at the corners, alongside fatigue or a sore tongue, is worth checking with a blood test for B12 and iron.
Is ghee better than petroleum jelly for chapped lips?
Both work as an occlusive moisturiser, sealing in existing moisture. Ghee has a pleasant traditional appeal and works well for most people; petroleum jelly is fragrance-free and slightly less likely to cause a reaction in very sensitive skin.
Most chapped lips are simply weather and habit, easily fixed with consistent moisturising. When the pattern is specifically at the corners and will not budge, that is your body’s way of asking for a closer look, not a stronger balm.
