Sun Spots (Solar Lentigines)

Sun spots are flat brown patches that build up on the skin the sun reaches most, such as the face, the backs of the hands and the chest. They are harmless, but they are a record of past sun exposure.

Start here

Sun spots are easy to treat and hard to prevent. A spot can usually be lifted off in a session or two, but nothing stops the next ten arriving if the sun exposure carries on unchanged. Have any flat brown spot looked at before it is treated - almost all are harmless, but a few things look just like a sun spot and are not, and freezing one removes the evidence rather than the problem. And put sunscreen on the backs of your hands; everyone forgets them, and they are what I hear the most regret about later.

Key Facts

−
How commonVery common. Most people with lighter skin tones have some by their forties, and heavy sun exposure or tanning brings them on earlier
Who gets itAnyone with years of accumulated sun exposure. Most common and most obvious on light and medium skin tones
Curable or managedIndividual spots can be removed and usually stay gone. New ones keep forming unless sun exposure changes
Prescription neededNo. Creams help slowly, and the fastest results come from in-office treatments
Time to improveCreams take three to six months. In-office treatment usually takes one or two sessions plus one to two weeks of healing

What It Is

−

A sun spot is a flat, sharply edged brown patch on skin that has had a lot of sun. They range from a few millimeters to more than a centimeter, tan to dark brown, and where there are many they can merge into larger patches. Nothing to feel, no itch, no scale.

They turn up where the sun lands most: the forehead and cheeks, the backs of the hands and forearms, the upper chest, shoulders, upper back and, in people with thinning hair, the scalp. The pattern often gives away someone's habits; drivers frequently have more on one side of the face and one forearm.

The medical name is solar lentigo, plural solar lentigines. Age spots and liver spots are both misleading names. Age matters only because sun exposure adds up, and the liver has nothing to do with it.

Freckles are easily confused with them. Freckles appear in childhood, are usually smaller, and darken in summer and fade in winter. Sun spots appear later, have sharper edges, and do not fade over winter - the most useful difference at home.

Sun spots are harmless and do not turn into anything else. They do show enough ultraviolet exposure to cause other changes, so someone with a lot of them is more likely to also have actinic keratoses - rough precancerous patches - and skin cancers. Read them as information, not a threat.

Symptoms

−
Flat brown spots

Face and Hands

Flat, evenly colored tan or brown spots with clear edges on the face, backs of the hands and forearms. They reflect years of sun exposure rather than age itself. They do not fade in winter the way a tan does.
Spots after sunburn

Shoulders and Back

Scattered spots across the shoulders, upper back and chest, often in people who have had blistering sunburns. They tend to appear in groups. Sun protection stops new ones more effectively than treatment removes old ones.
One that stands out

Changing Spot

A spot that is growing, darkening unevenly or looks different from the others around it. Ordinary sun spots stay stable and look like each other. One that does not fit deserves a proper look.

Where It Shows Up

−
Front view of a head with red marks across the forehead, on both cheeks, at both temples, on the nose and on the top of the scalp.
Forehead, cheeks and a thinning scalp
Sun spots turn up where the sun lands most and stay away from skin that is usually covered. On the face that means the forehead and the cheeks, plus the scalp in people with thinning hair. The pattern is often lopsided — drivers frequently have more on the side nearest the window.
Front view of a whole body with red marks on the backs of both hands, on both forearms, across the upper chest and over both shoulders.
Backs of the hands, forearms and upper chest
The backs of the hands are the site most people notice first, and the forearms and the upper chest follow. These are flat and smooth — if a patch feels rough like fine sandpaper, it is an actinic keratosis rather than a sun spot, and that one gets treated.
Back view of a whole body with red marks across both shoulders, the upper and middle back, the back of the neck and the head.
Shoulders and upper back
The shoulders and upper back collect them in anyone who has spent summers outdoors, and they are the ones nobody sees. They are harmless, and the reason to know them is so a changing spot among them is not written off as another one.

Pigment cells sit spaced evenly along the base of the top layer of skin. Each one hands a small, steady amount of pigment to the cells around it, so the color comes out even. The underside of that layer runs smooth, with nowhere for extra pigment to collect.

Ultraviolet light lands on the same areas over and over, in ordinary daily doses as much as in holidays and sunburns. Nothing is visible at this stage. It is the total across decades that counts, which is why spots turn up in middle age rather than after one summer.

In small patches, the pigment cells at the base of the top layer of skin become both more numerous and more active than the cells around them. That local cluster is what a sun spot actually is, and it is the step the lightening creams are aimed at.

The underside of the top skin layer thickens into small downward ridges, and the extra pigment collects in them. This is why a sun spot keeps a fixed shape with a sharp edge, and why it does not come and go the way a tan or a freckle does.

Every new dose of ultraviolet light darkens the spots already there and starts new clusters elsewhere on exposed skin. This is why removing one spot does nothing to prevent the next, and it is the step almost everything on the lists below is pushing on.

The outer film of dead cells and oil. It holds water in and keeps irritants out, and it is thinner than a sheet of paper. Almost every dry, itchy, stinging skin problem starts here.

The outer layer, and the only one anything in a jar reaches. It renews itself constantly: a cell made at the bottom takes about a month to reach the surface and flake off. Most of what a skincare product does, it does here.

The living layer underneath, holding the blood vessels, the nerves and the collagen. It is where lasting change happens and it is hard to reach: most of what is sold for the skin never gets this far.

Sun spots form in four steps, all driven by ultraviolet light adding up over years. First, light reaches the skin again and again - ordinary daily doses as much as holidays and sunburns. Second, in small patches the pigment cells at the base of the top skin layer become more numerous and more active than those around them; that cluster is the spot.

Third, the skin builds a structure that holds the pigment in place. The underside of the top layer thickens into small downward ridges where the extra pigment collects, which is why a sun spot has a fixed shape and a sharp edge and does not come and go the way a tan or a freckle does.

Fourth, more light keeps the process running. Each new dose darkens the spots already there and starts new clusters on exposed skin. Removing a spot does nothing to prevent the next one; sun protection is the only thing that changes the direction of travel.

Risk Factors

−

Sun spots are the arithmetic of a lifetime of sun exposure, and some people reach the total faster. Most of this is history rather than anything you can change now.

Sun exposure
Cumulative sun exposure
The main driver. The total across decades counts, not any single day, which is why spots appear in middle age.
Sun exposure
History of sunburns
Repeated burning, especially blistering burns, raises the risk of spots and of skin cancer.
Sun exposure
Tanning beds
A concentrated dose of the exact wavelengths that cause this.
Sun exposure
Outdoor work and sunny climates
Farming, construction, sports, sailing and high-sun regions all add up.
Sun exposure
Driving
Ultraviolet A passes through side windows, so many people have more spots on the side of the face and forearm nearest the window.
Inherited & age
Lighter skin tone
Skin that burns easily and tans poorly develops spots earlier and in greater numbers.
Inherited & age
Family history
How strongly skin responds to sun is partly inherited.
Inherited & age
Age
Not a cause in itself - older skin has had more time to accumulate exposure.
Medicines & treatments
Some medicines
A number of medicines make skin more sensitive to light. Never stop one on your own - ask your doctor.
Medicines & treatments
Past light-based medical treatment
Older treatments combining a medicine with ultraviolet light are linked to lentigines later.

Course

−

Sun spots build up gradually and get noticed suddenly, usually in a photograph or bright bathroom lighting. They do not turn into skin cancer, but skin carrying a lot of them has had enough ultraviolet exposure that other changes are more likely, so watch for rough scaly patches and any spot behaving differently from its neighbors.

First spotsThirties to forties
They start to appear

Most people see their first spots in their thirties or forties, earlier with heavy sun exposure or tanning beds.

Building upThe years after
Steady, not in waves

They accumulate steadily over years rather than arriving in a batch.

EstablishedAny time of year
They do not fade over winter

Individual spots do not go away on their own. Unlike a tan or a freckle they do not fade over winter, the most reliable way to tell them from freckles.

MergingLater years
Spots darken and join up

A spot may darken slightly over time, and clusters can merge into broader patches.

Backs of the handsUpper chest
After treatmentIf they are treated
Treated spots clear, new ones arrive

A spot treated with freezing, laser or a peel usually clears and does not come back there. New spots keep appearing while sun exposure continues, so treating without changing sun habits means a new crop in a few years. Daily sun protection slows the rate.

What Makes It Better & Worse

−

Removing spots does nothing to slow the process that makes them, so a routine that covers all four steps is what keeps them from coming back.

Every new dose of ultraviolet light darkens the spots already there and starts new clusters elsewhere on exposed skin. This is why removing one spot does nothing to prevent the next, and it is the step almost everything on the lists below is pushing on.

What helps

  • Daily broad-spectrum sunscreen SPF 30 or higher, hands and chest included, reapplied on days outside.
  • Shade, sleeves and a wide-brimmed hat Better than any sunscreen.

What makes it worse

  • Sun on unprotected skin Daily incidental exposure adds up to more than holidays do.
  • Tanning beds A concentrated dose of the wavelengths that cause sun spots.
  • Forgetting the hands, chest, ears and neck Where the most noticeable spots turn up later.
  • Sunscreen applied too thinly Real-world protection is far below the number on the bottle.
  • Window glass Ordinary glass lets longer ultraviolet wavelengths through.
  • Believing a base tan protects you A tan is damage, and it protects very little.
  • Medicines that increase sun sensitivity Ask your prescriber rather than stopping anything yourself.

What helps

  • A retinoid at night Speeds up shedding of pigmented surface cells.
  • Vitamin C and niacinamide Modest effects on pigment, easy long-term.
  • Hydroquinone in a short course The strongest topical for pigment, under a doctor's supervision.
  • Azelaic acid, kojic acid and cysteamine Alternatives if you cannot use hydroquinone.
  • Give creams three to six months Topical treatment is slow, and six weeks is stopping too early.

What makes it worse

  • Picking or scratching a treated spot A reliable way to swap it for a longer-lasting dark mark.

What helps

  • Cryotherapy A few seconds of liquid nitrogen per spot, with a risk of a pale mark.
  • Laser and intense pulsed light Breaks up pigment over one to three sessions, settings matched to your skin tone.
  • Chemical peels Lighten spots across a whole area such as the hands or chest.
  • Have spots checked before treating them Removing a spot that needed a biopsy is the one bad outcome here.

Over-the-Counter Products

−

Everything here you can buy without seeing anyone.

Broad-spectrum sunscreen
Broad-spectrum sunscreen
Always
The only thing on this page that changes the direction of travel. SPF 30 or higher, broad spectrum, on the face, ears, neck, chest and the backs of the hands every day, including cloudy days and days spent driving. It will not remove the spots you have, but it stops them darkening, slows new ones considerably, and protects the result of any treatment you pay for.
Six retinol products lined up, including SkinCeuticals Retinol 0.5, Murad, CeraVe, First Aid Beauty, RoC and Replenix16:9 hero for Retinol. Never cropped: the tone strip and the corner logo depend on the full frame.
Moderate evidence
Speeds up how quickly pigmented surface cells are shed, so spots lighten gradually from the top down. It is the over-the-counter option with the best evidence in sun spots, and it improves the surrounding sun-damaged skin at the same time. Start two or three nights a week to avoid irritation, and expect three to six months before the difference is obvious.
Four glycolic acid toner and liquid bottles lined up on white, one with its box16:9 hero for Glycolic Acid. Never cropped: the tone strip and the corner logo depend on the full frame.
Limited evidence
Loosens the pigmented cells at the surface so they shed sooner, which lifts a little color out of a spot over months. It works better as the thing that helps a lightening cream get in than as a treatment on its own. Used too often it leaves skin irritated and more sun-sensitive, which on this page is exactly the wrong direction.
Four cysteamine products: a Senté tube, an Omic+ cream and box, a 5% cysteamine serum dropper and a Cyspera bottle16:9 hero for Cysteamine. Never cropped: the tone strip and the corner logo depend on the full frame.
Limited evidence
Applied to dry skin, left for about fifteen minutes and washed off rather than left on overnight. It suits people who want a lightening step without hydroquinone, or something to hold a result between courses of it. Most of the trial evidence is in melasma rather than sun spots, and the smell is the usual reason people stop.
Four alpha arbutin products lined up on white: three dropper serums and a pink cream tube16:9 hero for Alpha Arbutin. Never cropped: the tone strip and the corner logo depend on the full frame.
Limited evidence
A gentler relative of hydroquinone that releases a small amount of it slowly in the skin. It is a reasonable long-term option on a spot you are lightening slowly, and it does not sting, which matters because irritation on a sun spot can leave a darker mark. The effect is mild and takes months.
Six vitamin C products on white, including La Roche-Posay, L'Oréal Revitalift, CeraVe, Vanicream, bliss and Olay16:9 hero for Vitamin C (L-Ascorbic Acid). Never cropped: the tone strip and the corner logo depend on the full frame.
Limited evidence
Lightens surface pigment modestly and adds a little to what sunscreen is doing during the day. It is easy to keep using for years, which is its real advantage here, since sun spots are a long game. On its own it will not clear an established spot.
Six niacinamide products on white, including The Ordinary 10% + Zinc 1%, Paula's Choice Booster and EltaMD UV ClearLabeled cutaway diagram of a single skin pore, headed Niacinamide. The epidermis is a brick-textured band across the top and the dermis is pink below it, with a yellow oil gland at the base of the pore and a small cluster of bacteria inside it. Two callout lines point in: decreases inflammation is drawn in dark navy as the main effect, and decreases oil production is drawn in gray as a lesser one. Nothing points at the dead cells blocking the pore.
Limited evidence
Slows the handover of pigment from pigment cells to the skin cells above them, so a spot fades a little rather than disappears. Its strength is that it is well tolerated and does not sting, so it sits comfortably alongside a retinol without making the skin sore. Modest on its own.
Five kojic acid products on white, including a turmeric serum, Medicube capsule cream, Admire My Skin and Seoul Ceuticals16:9 hero for Kojic Acid. Never cropped: the tone strip and the corner logo depend on the full frame.
Limited evidence
Blocks the same pigment-making enzyme hydroquinone does, more weakly. It is nearly always sold combined with other lightening ingredients, and the studies behind it are studies of those combinations. It stings some people, and irritation on a sun spot is not a neutral event, particularly on medium and deeper skin tones.
Freezing kits sold for warts
Freezing kits sold for warts
Never use
These are made for warts and are not accurate or gentle enough for a flat pigmented spot. On the face they can leave a permanent pale mark that is more noticeable than the spot was. The bigger problem is that they remove a spot nobody has examined, and that is the one thing this page asks you not to do.

Prescriptions

−

The basics stay put - a gentle cleanser, a moisturizer and a daily sunscreen are right whichever kind you have.

These need a prescription.

16:9 hero for Hydroquinone 4%. Never cropped: the tone strip and the corner logo depend on the full frame.Diagram: how Hydroquinone 4% works in the skin
Moderate evidence
The strongest cream for lightening a sun spot, applied thinly to the spot itself rather than the skin around it. It is used in a defined course of about three to four months with a break afterwards, not indefinitely, and it works best combined with a retinoid. It is slower than a single session of freezing or laser, and it is the option to prefer when treatment risk on deeper skin tones is the concern.
A plain white medicine tube lying at an angle on a white background, capped, labeled Tretinoin in black with a navy blue swoosh curving along its length.Diagram: how Tretinoin works in the skin
Moderate evidence
The prescription retinoid, and the one with real trial evidence in sun spots specifically. It lightens spots over about six to ten months and improves the sun-damaged skin around them at the same time. Expect dryness and flaking early on, and use it at night with daily sunscreen, since it leaves skin more sun-sensitive. Ask your doctor about it if you are pregnant or trying to become pregnant.
16:9 hero for Tazarotene. Never cropped: the tone strip and the corner logo depend on the full frame.Diagram: how Tazarotene works in the skin
Moderate evidence
A stronger retinoid with good trial results in sun spots, used when tretinoin has not done enough. It works the same way, a little faster, and irritates more, so it is often started a few nights a week. Ask your doctor about it if you are pregnant or trying to become pregnant.

Procedures

−

These are done in the office, usually over several visits.

16:9 hero for Cryotherapy (Liquid Nitrogen). Never cropped: the tone strip and the corner logo depend on the full frame.Diagram: how Cryotherapy (Liquid Nitrogen) works in the skin
Strong evidence
A few seconds of liquid nitrogen on each spot, done in the room, no anesthetic needed. The spot darkens, crusts and lifts off over one to two weeks. It suits a small number of spots rather than a whole hand, and its known cost is a permanent pale mark where too many pigment cells were destroyed, which is a bigger risk on medium and deeper skin tones.
16:9 hero for IPL (Intense Pulsed Light). Never cropped: the tone strip and the corner logo depend on the full frame.
IPL (Intense Pulsed Light)
Strong evidence
The best option when there are many spots across a whole area such as the face, chest or the backs of the hands. Usually one to three sessions, with the spots darkening and flaking off over one to two weeks after each. It is aimed at contrast between spot and skin, so it works best on lighter tones and is used cautiously or not at all on deep skin.
A gloved clinician passing a laser handpiece over a small tattoo on a patient's forearm16:9 hero for Q-Switched Laser Tattoo Removal. Never cropped: the tone strip and the corner logo depend on the full frame.
Strong evidence
The same pigment-shattering laser used for tattoo ink is used at low energy on individual sun spots, and it clears them reliably in one or two sessions. It is more precise than intense pulsed light and better for a few stubborn spots rather than a whole area. Settings have to be matched to the skin tone, since too much energy leaves a pale or a dark mark behind.
A gloved hand holding a picosecond laser handpiece against a woman's cheek as she lies on a treatment bed16:9 hero for Picosecond Laser. Never cropped: the tone strip and the corner logo depend on the full frame.
Moderate evidence
Delivers its energy in much shorter pulses, which breaks up pigment with less heat spilling into the skin around it. That lower heat is the reason it is often chosen for medium and deeper skin tones, where a darker mark afterwards is the main worry. It costs more than the older lasers and the results in sun spots are broadly similar.
A small clear glass bowl holding a shallow pool of pale amber liquid on a white background, with a white fan-shaped brush lying beside it, bristles resting against the bowl.Diagram: how Chemical Peel works in the skin
Moderate evidence
Lightens spots across a whole area rather than one at a time, which suits the backs of the hands, the forearms and the chest where spots are scattered widely. Usually a course rather than a single treatment, and the result is a general evening out rather than each spot disappearing. Depth matters: a peel strong enough to leave the skin raw can leave a darker mark instead.
16:9 hero for Fraxel (Nonablative Fractional Laser). Never cropped: the tone strip and the corner logo depend on the full frame.
Fraxel (Nonablative Fractional Laser)
Limited evidence
Treats the sun-damaged skin as a whole rather than targeting individual spots, so it improves texture and fine lines alongside the pigment. That makes it a reasonable choice when the spots are only part of what is bothering you. For clearing spots alone it is slower, dearer and less precise than freezing or a pigment laser.
16:9 hero for Microdermabrasion. Never cropped: the tone strip and the corner logo depend on the full frame.Diagram: how Microdermabrasion works in the skin
Weak evidence
Polishes off the very top layer of skin, which makes it briefly smoother and brighter. The pigment in a sun spot is held in ridges below that layer, so it is not reached. It is often sold as a treatment for spots and it is not one, and repeated sessions can irritate skin enough to leave marks of their own.

When to See a Dermatologist

−

Have a flat brown spot checked before anyone treats it - almost all are harmless, but a few skin cancers start out looking like an ordinary sun spot, and freezing or lasering one removes the appearance without addressing the problem. Book promptly if a spot is growing, changing shape or color, has more than one color, a ragged or blurred edge, is itchy, bleeding or crusting, or looks unlike your other spots. Book too if the area feels rough or scaly rather than smooth, which suggests a precancerous patch, or if you have never had a skin check. Most are diagnosed by eye in a couple of minutes, with a dermatoscope when there is doubt and a biopsy only when the appearance is atypical.

Complications

Lookalikes

−

Seborrheic Keratosis

The commonest thing mistaken for a sun spot, because both are brown patches on sun-exposed skin in the same age group. The difference is felt rather than seen. A seborrheic keratosis is raised and waxy, and a fingertip run across it catches on a slightly rough, stuck-on surface. A sun spot is completely flat and smooth. Neither is dangerous, but they are removed in different ways.

Actinic Keratosis

Both turn up on the same sun-damaged skin and often side by side on the same hand or forehead. An actinic keratosis feels rough and scaly, like fine sandpaper, and is often easier to feel with a fingertip than to see. A sun spot is smooth. This one matters because it is a precancerous patch and is treated, while a sun spot is only a cosmetic decision.

Melanoma

The one that has to be excluded before anything is treated. An early melanoma on sun-damaged skin can look flat and brown like everything else there. What separates it is that it is changing, growing, carries more than one color, has a ragged or blurred edge, or simply looks unlike every other spot you have. Ordinary sun spots stay stable and resemble each other.

Myths

+
  • "Liver spots mean there is something wrong with my liver." An old, incorrect idea. Sun spots have nothing to do with the liver or any internal organ - ultraviolet light causes them.
  • "They will fade over the winter." Freckles do that; sun spots do not. A spot that fades in winter and returns in summer is more likely a freckle or melasma, which changes what treatment makes sense.
  • "A base tan protects me from getting more." A tan is the skin's damage response and protects very little. Building one delivers a big dose of the light that causes sun spots.
  • "They are a form of skin cancer." Sun spots are harmless. A few skin cancers do look like one early on, so a spot that is changing, growing, uneven in color or unlike its neighbors should be checked rather than treated blind.
  • "You can freeze them off at home." Over-the-counter freezing kits are made for warts, not precise enough for a flat pigmented spot. On the face they can leave a permanent pale mark - and nobody has examined the spot.
  • "Only fair skin gets sun damage." Sun spots occur on all skin tones. On deeper skin tones sun damage more often shows as uneven tone or long-lasting dark marks, but the damage underneath is the same and sunscreen matters just as much.
  • "Sunscreen is pointless once I already have them." It will not remove existing spots, but it slows new ones, stops the ones you have darkening, and protects any treatment result. Without it, treated skin redevelops spots within a few years.

Questions Patients Ask

+

Are sun spots dangerous?

The spots are harmless and do not turn into cancer. What they indicate matters - that much sun exposure makes other changes more likely, so watch and protect those areas.

How do I tell a sun spot from something serious?

The reassuring pattern is flat, one even color, a clear edge, stable over time, similar to its neighbors. The pattern that needs a check is changing, growing, more than one color, a ragged or blurred edge, itching, bleeding, or a spot unlike the rest. Being unsure is a reason to have it looked at, not to worry.

What is the fastest way to get rid of them?

In-office treatment. Freezing works for a few spots; laser or intense pulsed light for many, usually over one to three sessions. Expect them to darken and flake off over one to two weeks. Creams work far more slowly.

Will they come back after treatment?

The individual spot usually does not return. New ones keep appearing on sun-exposed skin unless the sun protection changes, which is why people who treat spots and change nothing else are back within a few years.

Do sunscreen and creams help spots I already have?

Sunscreen does not remove them, but it stops them darkening and slows new ones. Retinoids, vitamin C, niacinamide and short courses of hydroquinone lighten existing spots over three to six months, more gently than a procedure.

I have deeper skin - is freezing a good option for me?

The one to be most cautious about. Freezing can destroy the pigment cells and leave a permanent pale mark, more noticeable on deeper skin tones and harder to correct than the original spot. Topical treatment first, conservative settings, a test spot, and a provider who treats deeper skin tones regularly is the safer path.
