Lips are one of the first places to show sun damage, dryness and age, yet they are routinely left out of skincare routines. We layer actives over the rest of the face and reach for a tinted balm on the lips. The thing is, a lot of what bothers people about their lips (dryness, a faded outline, fine vertical lines, darkening) is a skin and sun problem rather than a volume one, and it responds to proper lip skincare. Plenty of people weigh up lip fillers, but fillers add volume, they do not fix texture, tone or sun damage. The foundation for healthy, youthful-looking lips is simpler than that. It comes down to daily SPF, gentle exfoliation, consistent hydration and, where it helps, a retinoid on the skin around the mouth. Here is how to look after your lips properly.
Why does the skin on your lips need different care?
The skin on your lips is not like the skin anywhere else on your face. It is much thinner, it has very few oil glands and almost no sweat glands, and it holds very little melanin, the pigment that gives skin its colour and offers some natural protection from the sun. That combination is why lips dry out and chap so easily, why they have so little defence against UV and why they tend to show age early. It helps to think of your lips in two parts. The coloured part itself (the vermilion) is delicate, mucosal and easily irritated, whilst the skin around the mouth behaves more like normal facial skin and is where most active treatments are used. Good lip care looks after both.
What does a good lip care routine look like?
A good routine comes down to a few simple, consistent habits rather than a cupboard full of products. These are the ones that make the biggest difference.
- Exfoliate gently, about once a week. Lips shed dead skin just like the rest of your face, and a soft lip scrub or a damp flannel lifts away flakiness and leaves them smoother. Be gentle, because over-scrubbing irritates the delicate surface and makes dryness worse.
- Hydrate and seal in moisture. Look for a balm that pairs humectants that draw in water, like hyaluronic acid and glycerin, with richer ingredients that lock it in, like shea butter, squalane and ceramides. For very dry or cracked lips, a plain occlusive such as petrolatum over the top overnight works beautifully.
- Wear SPF every day. This is the step most people skip. A lip balm with SPF 30 or higher protects against the sun damage that drives ageing, dryness and pigmentation, and there is more on why this matters below.
- Leave them alone. Licking your lips feels soothing but dries them out as the saliva evaporates, and picking at flakes damages the surface. Both keep lips stuck in a cycle of chapping.
- Remove long-wear lipstick kindly. Matte and long-wear formulas are drying, so take them off with a gentle balm or a cleansing oil rather than rubbing, and follow with your usual balm.
Why is sun protection so important for your lips?
Your lips have very little of the natural pigment that shields the rest of your skin from UV, which leaves them particularly exposed. Over time, sun on the lips drives the same problems it causes elsewhere, including pigmentation, fine lines and a loss of definition around the lip border. The lower lip in particular takes the brunt of overhead sun, and persistent sun damage there (a condition called actinic cheilitis, where the lip becomes dry, scaly and rough) is also linked to skin cancer of the lip. None of this is a reason to worry, but it is a good reason to treat your lips like any other exposed skin. A daily SPF 30 lip balm, reapplied through the day and especially after eating, drinking or time outdoors, is the single most protective habit in any lip routine.
How do you keep your lips soft and hydrated?
Chapping happens when the lips lose water faster than they can hold onto it. The fix is the same three-part approach that works for dry skin anywhere, combining humectants that attract moisture, emollients that soften and occlusives that seal it in (the same ingredients in the routine above). A thicker balm or an overnight lip mask is worth using before bed, when lips lose the most moisture. It also helps to protect your skin barrier by avoiding harsh, fragranced or strongly flavoured lip products, which are a common and overlooked cause of irritation and can leave lips drier than before. And the simplest measure of all is to stop licking and picking, which quietly undoes everything else.
What can you do about fine lines around your lips?
The fine vertical lines that appear on and above the top lip (sometimes called lip lines or smoker’s lines) come from a mix of sun damage, the natural loss of collagen with age, the repetitive pursing movements of the mouth and smoking. The reassuring part is that the skin around the mouth responds well to skincare.
Topical tretinoin is the best-evidenced option, and a 2022 systematic review of randomised trials found it improved wrinkling and mottled pigmentation by stimulating collagen, with results building over months. Daily SPF and good hydration support it. It is worth being realistic about the limits, though. Tretinoin is used on the skin around the mouth rather than on the lip itself, and whilst it softens early lines and texture, deeper static lines and genuine volume loss are a different problem that skincare cannot fully correct. That is the point at which some people consider treatments like fillers, which our lip fillers guide explains. For the full rundown of what helps lip lines specifically, see our guide on how to get rid of lip lines.
What about dark or uneven lips?
Lips can darken or look blotchy for a number of reasons, and identifying the cause matters because it guides what actually helps. The common drivers are sun exposure, smoking (which causes a specific darkening known as smoker’s melanosis), friction and habit, certain medications and hormonal or inflammatory pigmentation such as melasma or the marks left after a healed cold sore (post-inflammatory hyperpigmentation). A review of lip pigmentation lists all of these among the usual causes. The everyday basics do help, including daily SPF, stopping smoking and gentle, fragrance-free lip care. It is honest to say that darkening of the lip itself can be stubborn and slow to shift, which is exactly why getting the cause right matters so much. Our dedicated page on lip hyperpigmentation goes through the causes and treatment options in detail.
When should you see a doctor about your lips?
Most lip concerns are cosmetic and respond to good skincare, but a few warrant a professional opinion. A new, changing or persistent dark spot or patch on the lip should always be checked. It is usually a harmless freckle-like mark (a labial melanotic macule), but the same review notes that lip pigmentation can occasionally signal something more serious, including melanoma, so it is not something to self-diagnose. Persistent dryness, scaling or roughness on the lower lip that does not settle is also worth reviewing, as is any sore that fails to heal. And if fine lines or pigmentation around the mouth bother you, a treatment tailored to your skin, for example a prescription retinoid or pigment-targeting actives, will do more than any single off-the-shelf balm.
