Sun spots and age spots are flat brown spots caused mainly by years of sun exposure. They are usually harmless and respond well to pigment lasers, IPL and some topical treatments. A dermatologist should check spots first, because melasma, raised growths and, rarely, skin cancer can look similar and need a different approach.
What Are Sun Spots, Age Spots and Other Pigmentation?
Pigmentation means areas of skin that are darker than the surrounding skin. It is caused by extra melanin or by a build-up of pigment-producing cells. The terms sun spot and age spot are often used for the same thing: flat brown spots called solar lentigines. They appear on areas that get the most sun, such as the face, the backs of the hands, the shoulders and the forearms.
| Type | Appearance | Main cause |
|---|---|---|
| Solar lentigines (sun spots, age spots) | Flat, light to dark brown, sharp edges | Long-term sun exposure |
| Freckles | Small, light brown, darker in summer | Genetics and sun |
| Seborrheic keratoses | Raised, waxy or rough brown growths | Aging and genetics |
| Melasma | Larger symmetrical patches on the cheeks | Hormones and light |
| Post-inflammatory hyperpigmentation | Dark marks after acne or irritation | Inflammation |
Why Sun Spots Appear With Age
Sun spots are a sign of accumulated sun damage. They usually appear after the age of 40, but people who spent a lot of time outdoors when young can develop them in their 20s and 30s. Unlike freckles, they do not fade in winter.
Spots That Are Not Simple Pigmentation
Some brown spots are not just extra pigment. Seborrheic keratoses are raised growths that feel rough or waxy and are usually removed rather than lightened. A spot that is changing, bleeding or irregular in color needs a medical check before any cosmetic treatment.
How Do Dermatologists Tell Pigment Spots Apart?
Correct diagnosis comes first, because each type responds to different treatment. A dermatologist looks at the color, edges, texture and pattern of each spot, often with a dermatoscope, a handheld magnifier with a light. You can read more in how dermatologists assess your skin before recommending treatment.
Warning Signs to Check Early
Doctors use the ABCDE rule to look for spots that might be melanoma, a type of skin cancer.
- Asymmetry: one half does not match the other.
- Border: edges are irregular or blurred.
- Color: several shades of brown, black, red or blue.
- Diameter: larger than about 6 mm, although melanomas can be smaller.
- Evolving: the spot changes in size, shape, color or feel.
If a spot shows any of these signs, ask for a medical examination rather than cosmetic treatment.
Questions the Doctor May Ask
To choose the right treatment, the dermatologist usually asks how long you have had the spots, whether any of them have changed recently, how much time you spend in the sun and whether you have had laser, peel or lightening treatment before. They also ask about medications that make skin sensitive to light, a history of cold sores, pregnancy plans and how much downtime you can accept. Answering these questions clearly helps the doctor balance a good result with a low risk of side effects, especially if you are visiting Seoul for a short stay and need to plan sessions around your trip.
Which Treatments Remove or Lighten Sun Spots?
Once a spot is confirmed to be a harmless sun spot, several treatments can lighten or remove it.
| Treatment | How it works | What to expect |
|---|---|---|
| Pigment laser | Short pulses of laser light break up pigment | Spots darken and flake off over one to two weeks |
| IPL | Broad-spectrum light targets brown and red pigment | Best for many small spots and overall uneven tone |
| Cryotherapy with liquid nitrogen | Freezes the spot so it peels away | Used for single spots by a doctor |
| Chemical peels | Remove the pigmented outer layer | Several sessions for lighter spots |
| Topical creams | Retinoids or lightening agents fade pigment slowly | Takes months and works best on light spots |

Laser Versus IPL for Sun Spots
Pigment laser may suit you if
- You have a few distinct spots
- You want a targeted result on each spot
- You can avoid strong sun for a few weeks
IPL may suit you if
- You have many small spots and some redness
- You want an overall more even tone
- You prefer a series of gentler sessions
What Happens After a Pigment Laser Session
Treated spots usually turn darker and form a thin crust within a day or two. This crust flakes off on its own within about a week or two. You should not pick at it. Mild redness can last a few days. Some people need a second session for spots that remain.
How Is Other Pigmentation Treated?
Not all pigmentation responds to the same methods.
- Melasma: treated gently with sun protection, creams and low-energy laser toning, because strong treatment can make it darker. See what causes melasma and which dermatology treatments may help.
- Post-acne marks: usually fade with time, topical treatment and mild peels, once acne is under control.
- Freckles: respond to pigment lasers or IPL, but return with sun exposure.
- Seborrheic keratoses: are removed with cryotherapy, laser or minor procedures rather than lightened.
Pigmentation in Darker Skin Tones
People with medium and darker skin tones have a higher risk of new dark marks after laser or peel treatment. Dermatologists reduce this risk by choosing suitable devices, starting with lower settings, testing a small area and preparing the skin with topical treatment before procedures.
How Do You Prepare and Recover From Treatment?
The doctor confirms the type of each spot and checks for warning signs.
You stop strong exfoliants a few days before, avoid tanning and protect your skin from the sun.
The laser, IPL or other method is applied, usually in a short session.
You keep the area clean, apply moisturizer and sunscreen and let crusts fall off naturally.
The dermatologist checks results and plans a follow-up session if needed.
Aftercare Tips for Lasting Results
- Use broad-spectrum sunscreen of SPF 30 or higher every day.
- Avoid sunbathing and tanning for several weeks after treatment.
- Do not scratch or peel crusts.
- Avoid harsh exfoliants until the skin has healed.
- Wear a hat when you spend time outdoors.
Can Sun Spots Come Back After Treatment?
Treated spots often stay lighter for a long time, but new spots can form with continued sun exposure, and some treated spots can return. Daily sun protection is the most effective way to keep results. Many people choose a maintenance session every year or two.
