Sun spots — also called solar lentigines, age spots or liver spots — are flat brown marks from years of UV exposure. They are harmless and do not turn into cancer. The catch is that an early melanoma or a lentigo maligna can occasionally look like one, so a spot that looks or behaves differently from your others is worth a doctor’s eye.
Sun spots (solar lentigines)Flat brown marks from years of sunCan a sun spot turn into cancer?
No — a true sun spot cannot turn into skin cancer. Solar lentigines are simply clusters of pigment from UV exposure and have no cancer potential. The real risk is the reverse: mistaking an early melanoma for a harmless sun spot, because both can be flat and brown. So the useful question isn’t “will this become cancer” — it’s “is this actually a sun spot, or something pretending to be one?”
What does a harmless sun spot look like?
A harmless sun spot is flat, evenly coloured, stable, and looks like your other sun spots. In 18 years of skin-cancer medicine, the reassuring ones nearly always share these features:
- Flat and even in colour — tan to brown, no black, blue or red.
- On sun-exposed skin — face, backs of hands, shoulders, upper back.
- Well-defined edges; round or oval.
- Stable — not growing or changing, and much like your others.
Sun spots on the face — and “white” sun spots
The face is the most common place to notice sun spots, and facial ones follow the same rule: flat, even and stable is reassuring. The face is also where an early lentigo maligna appears, so a facial patch that is slowly enlarging, darkening or turning uneven deserves a look rather than being dismissed as “just a sun spot”.
Small white spots on sun-exposed skin — often the shins and forearms — are usually a separate, harmless condition where the skin has simply lost pigment in tiny patches. They are not cancer and need no treatment, though, like brown sun spots, they are a reminder of cumulative UV. Have any white or pale area checked if it becomes scaly, grows, or will not heal.
Sun spot vs melanoma: how to tell them apart
A harmless sun spot is regular on every measure; a melanoma tends to break the pattern (the ABCDEs).
| Feature | Harmless sun spot | Worth checking |
|---|---|---|
| Colour | One even brown | Several colours, black or red |
| Border | Smooth, well-defined | Irregular or notched |
| Shape | Round, symmetric | Asymmetric |
| Over time | Stable | Growing, itching or bleeding |
When should I get a sun spot checked?
See a doctor about a pigmented spot if it is changing, uneven or multi-coloured, has an irregular border, is growing, itches or bleeds, or simply stands out from your other spots — the “ugly duckling”. When in doubt, have it looked at: melanoma is highly treatable when it is caught early. See also age spots and liver spots.
Can sun spots be removed?
Yes — harmless sun spots can be faded cosmetically with topical treatments or in-clinic options. But it is sensible to have a spot confirmed benign by a doctor first, so you are never treating over something that deserved a proper look.
Not sure? Get it reviewed
Upload a photo and Dr Walia will provide written next-step advice from the submitted photographs, including when an in-person examination is appropriate. Get your spot reviewed — $49, or check it free with our AI first.

Not a diagnosis; a doctor’s opinion on a photo cannot rule skin cancer in or out.

Are age spots, liver spots and sun spots the same thing?
Yes. These common names usually refer to solar lentigines: flat, evenly pigmented marks that develop on sun-exposed skin over time. The name “liver spot” describes the colour and does not mean there is a liver problem.
When a supposed age spot needs assessment
A genuine solar lentigo is usually stable and evenly coloured. Arrange an in-person examination if a mark is new, changing, spreading, irregular, multi-coloured, bleeding, itching or unlike your other spots. Melanoma and lentigo maligna can sometimes resemble a flat sun spot, and a photograph cannot safely settle that distinction.
