Lips are a special skin: no sebaceous glands, very thin and almost without protective pigment. So they are the first to dry, crack and burn. The paradox is that many "healing" balms dry more — because of menthol, fragrance and acids. Let us work out what really restores the lips.
Lips get dry because they have no sebaceous glands, a thin outer layer and little melanin — they are defenceless against cold, wind and sun. They are restored by occlusives (petroleum jelly/petrolatum, lanolin) and humectants (hyaluronic acid, glycerin), as well as SPF 30+. Irritating and worsening: menthol, camphor, fragrance, salicylic acid, and the habit of licking and biting. If it does not heal in two to three weeks — it may be cheilitis; see a doctor.
01Why lips get dry
The lips have no sebaceous glands, so they do not produce their own protective film. The outer layer is thin, and there is little melanin — meaning weak protection from UV. Add cold, wind, the dry air of heating and the habit of licking the lips — and you get cracks, flaking, tightness. Licking seems like a rescue, but saliva evaporates and dries even more, leaving the lips drier than they were.
02What heals and what irritates
Helpful: petroleum jelly/petrolatum and other occlusives (they seal moisture better than waxes and oils), lanolin, hyaluronic acid and glycerin (draw in moisture), ceramides. Look for "fragrance-free" and "hypoallergenic" marks. Irritating and drying: menthol, camphor, eucalyptus, flavourings (especially cinnamon, citrus, mint), salicylic acid, denatured alcohol. If a balm stings, tingles or burns — this is not "working", it is irritation; change the product.
03How to care
Apply balm several times a day and before bed; with severe dryness — a thick petroleum jelly ointment at night. By day — a balm with SPF 30+, even in winter (the sun burns lips easily). Drink enough water, humidify the air at home, do not pick off the flaking (it provokes cracks and bleeding). It is better to avoid harsh scrubs — gentler to soften and remove the scales with a damp cloth. Noticeable improvement usually in two to three weeks.
- Licking and biting the lips. Saliva evaporates and dries; rubbing increases inflammation.
- Balms with menthol/camphor/fragrance. A pleasant coolness, but irritation and dryness.
- Harsh scrubbing of cracked lips. Injures the already damaged skin.
- Salicylic acid in a balm. On the delicate skin of the lips it often over-dries.
- Ignoring sunscreen. Years of sun lead to actinic cheilitis (a precancerous condition).

05Common questions
Why does a balm seem addictive — without it things are worse?
Usually it is not about "addiction", but an irritating formula (menthol, fragrance) or the fact that the cause of the dryness has not been removed. Switch to a fragrance-free occlusive and stop licking.
What to do if lips crack at the corners?
Cracks at the corners of the mouth (angular cheilitis) are often linked to fungus/bacteria and require separate treatment — if it does not pass, see a doctor.
When is lip dryness a reason to see a doctor?
If it does not heal in two to three weeks, there are persistent white/flaking patches, especially on the lower lip — it may be allergy, infection or actinic cheilitis.
