Age Spots (Liver Spots): Complete Guide to Causes, Treatment & Prevention

Medically reviewed by Dr. Baraa Alnahhal, MD. Last updated: September 2026.

Age spots (also called sunspots, liver spots, or solar lentigines) are small, flat, dark areas on the skin — usually tan to dark brown — that appear on sun-exposed areas such as the face, hands, shoulders, and arms. They are caused by overactive pigment cells: UV light speeds up melanin production, and after years of sun exposure the pigment clumps together. True age spots are harmless and need no treatment, but they are a sign the skin has received a lot of sun. If a spot is black, growing, irregular, oddly colored, or bleeding, see a doctor — those changes can signal melanoma. For cosmetic reasons, they can be lightened or removed with creams, lasers, freezing, or peels, and the best defense is sunscreen and sun avoidance.

TL;DR

• What they are: Small, flat dark patches (tan to dark brown) on sun-exposed skin — also called sunspots, liver spots, or solar lentigines.

• Who gets them: Very common in adults over 50, but younger people who spend time in the sun can get them too.

• Why they form: UV light makes overactive pigment cells produce melanin that clumps at the base of the epidermis.

• They never fade: Unlike freckles, age spots don't fade without sun — and they can grow or group together.

• Harmless, but check changes: True age spots need no treatment — see a doctor for any spot that is black, growing, has an irregular border, odd colors, or bleeds.

• Six removal options: Prescription creams, laser/intense pulsed light, cryotherapy (freezing), dermabrasion, microdermabrasion, and chemical peels — usually not covered by insurance.

• Prevention: Avoid the sun 10 a.m.–2 p.m., use broad-spectrum SPF 30+ sunscreen, and cover up with protective clothing and a broad-brimmed hat.

What Are Age Spots?

Age spots are small, flat dark areas on the skin. They vary in size and usually appear on areas exposed to the sun, such as the face, hands, shoulders, and arms. You may hear them called sunspots, liver spots, or solar lentigines — all the same thing.

The good news: true age spots don't need treatment. They are a sign the skin has received a lot of sun exposure and are, in a sense, an attempt by your skin to protect itself from more sun damage. For cosmetic reasons, though, they can be lightened or removed — and knowing how requires understanding how they form.

How Age Spots Form

Age spots are caused by overactive pigment cells. Here is the mechanism: ultraviolet (UV) light speeds up the production of melanin, the natural pigment that gives skin its color. On skin that has had years of sun exposure, age spots appear when melanin becomes clumped or is produced in high concentrations.

Commercial tanning lamps and beds can cause age spots too — they deliver concentrated UV light without the sun's schedule.

How age spots form: UV light drives overactive pigment cells to clump melanin at the base of the epidermis. True age spots are harmless, but black or changing spots always deserve a doctor's check. Source: rinnit.com

Symptoms: What Age Spots Look Like

Age spots may affect people of all skin types, but they're more common in adults with skin that sunburns easily. A key distinction: unlike freckles, which are common in children and fade with no sun exposure, age spots don't fade. They may grow in size and group together, giving the skin a speckled or mottled appearance — very common on the back of the hand.

Feature	Description
Shape	Flat, oval areas of increased pigmentation
Color	Usually tan to dark brown
Location	The skin that has had the most sun exposure over the years — backs of hands, tops of feet, face, shoulders, upper back
Size	From freckle size to about 1/2 inch (13 mm) across
Pattern	Can group together, making them more noticeable

When to See a Doctor: The Melanoma Warning

Age spots don't require medical care. However, you should have your doctor look at spots that are black or have changed in appearance — these changes can be signs of melanoma, a serious form of skin cancer. It's best to have any new skin changes evaluated by a doctor, especially if a spot:

Warning Sign	Why It Matters
Is black	Color change can signal melanoma
Is increasing in size	Growing spots need evaluation
Has an irregular border	Ragged edges are a classic warning sign
Has an unusual combination of colors	Multiple colors in one spot are a red flag
Is bleeding	Bleeding without injury is never normal

The reason accurate identification matters: it's important to distinguish age spots from other skin disorders because the treatments differ, and using the wrong procedure may delay other needed therapy.

Risk Factors

You might be more likely to develop age spots if you have a history of frequent or intense sun exposure or sunburn. If you have skin that burns easily and spend a lot of time in the sun, your risk rises further.

Diagnosis: How Doctors Confirm Age Spots

Diagnosis is usually straightforward — and sometimes includes a small procedure for certainty:

Diagnostic Step	What Happens
Visual inspection	The doctor can usually diagnose age spots by looking at your skin
Skin biopsy	A small sample of skin is removed and examined in a lab — usually in the doctor's office with a local anesthetic; helps distinguish an age spot from conditions such as lentigo maligna, a type of skin cancer

Treatment: Six Options to Lighten or Remove

If you want your age spots to be less noticeable, treatments are available to lighten or remove them. One technical detail drives all of them: the pigment is located at the base of the epidermis — the topmost layer of skin — so any lightening treatment must penetrate this layer.

Treatment	How It Works	What to Expect
Prescription medications	Bleaching creams (hydroquinone) alone or with retinoids (tretinoin) and a mild steroid	Gradually fade spots over several months; may cause temporary itching, redness, burning, or dryness
Laser and intense pulsed light	Destroys melanin-producing cells (melanocytes) without damaging the skin's surface; ablative lasers remove the epidermis	Typically two to three sessions
Freezing (cryotherapy)	A cotton-tipped swab applies liquid nitrogen for five seconds or less, destroying extra pigment; skin appears lighter as it heals; spray freezing for small groupings	May temporarily irritate; slight risk of permanent scarring or discoloration
Dermabrasion	Sands down the surface layer of skin with a rapidly rotating brush; new skin grows in its place	May need more than one session; temporary redness, scabbing, swelling; pinkness can take months to fade
Microdermabrasion	A less aggressive approach than dermabrasion; smooths mild skin blemishes	Series of procedures over months for modest, temporary results; slight redness or stinging; can worsen rosacea or tiny red facial veins
Chemical peel	A chemical solution removes the top skin layers; new, smoother skin replaces them	Possible scarring, infection, or lightening/darkening of skin; redness lasts up to several weeks; several treatments may be needed

Practical Considerations

The skin-removing therapies are usually done in a doctor's office and don't require hospitalization, and results take weeks to months. Two important realities to plan for:

Insurance: Because age spot treatments are considered cosmetic, they typically aren't covered by insurance.

Choosing a provider: Because the procedures can have side effects, discuss your options carefully with a doctor who specializes in skin conditions (a dermatologist). Make sure your dermatologist is specially trained and experienced in the technique you're considering.

After treatment: When outdoors, you'll need to use a broad-spectrum sunscreen with an SPF of at least 30 and wear protective clothing — without this, new spots will form.

Self-Care: At-Home Options

Many nonprescription fade creams and lotions are available to lighten age spots. These may improve the appearance depending on how dark the spots are and how often you apply the cream — and you might need regular use for several weeks or months before noticing results.

If you want to try an over-the-counter fade cream, choose one containing hydroquinone, glycolic acid, or kojic acid. Note that some products — especially those containing hydroquinone — may cause skin irritation. You could also simply apply makeup to make age spots less noticeable.

Prevention: Limit Sun Exposure

To help avoid age spots — and new spots after treatment — follow these habits for limiting sun exposure:

Prevention Habit	What To Do
Avoid peak sun	Avoid the sun between 10 a.m. and 2 p.m., when the rays are most intense; schedule outdoor activities for other times
Use sunscreen	Apply a broad-spectrum SPF of at least 30, 15–30 minutes before going outdoors; apply generously and reapply every two hours — more often if swimming or perspiring
Cover up	Wear tightly woven clothing covering arms and legs and a broad-brimmed hat (more protection than a baseball cap or golf visor); look for clothing labeled UPF 40–50 for the best protection

Preparing for Your Appointment

You're likely to start by seeing your primary care doctor, who may then refer you to a dermatologist.

What Your Doctor Will Ask

Be ready to answer questions such as: When did you first notice the spots on your skin? Did they appear gradually or quickly? Have you noticed any other changes in the appearance of your skin? Is the condition itchy, tender, or otherwise bothersome? Have you experienced frequent or severe sunburns? How often are you exposed to the sun or UV radiation? Do you regularly protect your skin, and what kind of sun protection do you use? Do you have a family history of age spots or skin cancer? What medications do you take?

Questions to Ask Your Doctor

• What suspicious changes in my skin should I look for?

• If the spots are age spots, what can I do to improve the appearance of my skin?

• Do treatments make them go away completely, or do they just lighten the age spots?

• Could these spots turn into skin cancer?

Frequently Asked Questions

What are age spots, and why are they called liver spots?

Age spots are small, flat, dark areas on the skin that vary in size and appear on sun-exposed areas. They are also called sunspots, liver spots, and solar lentigines — different names for the same harmless sun-related pigmentation.

What causes age spots?

Age spots are caused by overactive pigment cells. UV light speeds up melanin production, and on skin with years of sun exposure, melanin becomes clumped or produced in high concentrations. Commercial tanning lamps and beds can also cause them.

Are age spots dangerous?

True age spots are harmless and need no medical treatment. However, have a doctor check any spot that is black or has changed — changes can be signs of melanoma, a serious skin cancer.

Do age spots go away on their own?

No. Unlike freckles, which fade without sun exposure, age spots don't fade. They can grow in size and group together, giving skin a speckled appearance.

How can age spots be removed?

Six main options exist: prescription bleaching creams (hydroquinone with retinoids), laser and intense pulsed light, freezing with liquid nitrogen, dermabrasion, microdermabrasion, and chemical peels. Treatments are cosmetic, so they usually aren't covered by insurance.

How can I prevent new age spots?

Avoid the sun between 10 a.m. and 2 p.m., apply broad-spectrum SPF 30+ sunscreen before going outdoors and reapply every two hours, and cover up with tightly woven clothing and a broad-brimmed hat. UPF 40–50 clothing offers the best fabric protection.

Conclusion

Three lessons anchor this guide: age spots are your skin's sun diary — every flat tan-to-brown patch on your hands, face, and shoulders records years of UV exposure, and they never fade on their own the way freckles do; harmless doesn't mean unmonitored — a spot that is black, growing, irregular, oddly colored, or bleeding is not an age spot, and getting it checked promptly can catch melanoma early; and removal is possible but patience and diligence are required — all six treatments take weeks to months, carry side effects, cost out of pocket, and must be followed by vigilant sun protection or new spots will simply return.

This guide walked you through what age spots are, exactly how they form in the epidermis, the freckle comparison, every warning sign that calls for a doctor, the biopsy backup, all six removal options with their side effects, at-home fade creams, and the three prevention habits that work. If you've noticed dark patches appearing after years in the sun, the first conversation to have is with your doctor — to confirm what they are before deciding what to do about them.
