Melasma vs hyperpigmentation vs sun spots
Hyperpigmentation is the umbrella term for skin darker than its surroundings. Melasma and sun spots both sit under it. Melasma forms larger, matching patches on both cheeks or the forehead. Sun spots are small, flat ovals up to about half an inch wide on sun-exposed skin. Marks after a pimple usually fade in 6 to 12 months.
Published · Written by Kay Woodson · Results vary.The three, side by side
| Melasma | Sun spots (liver or age spots) | Post-inflammatory hyperpigmentation | |
|---|---|---|---|
| Where | Cheeks, forehead, chin, above the upper lip; less often arms and neck | Face, hands, neck, arms: skin that gets sun | Wherever skin was inflamed or hurt |
| Pattern | Usually on both sides of the face, matching | Scattered, one by one | Follows the old pimple, scratch or rash |
| Shape and size | Patches, often larger and blotchy | Flat, round or oval, freckle-sized to about 13 mm | The size of what caused it |
| Color | Tan, brown, grayish brown or bluish gray | Tan to dark brown | Brown; deeper marks look slate blue to gray |
| Who gets it most | Women, medium to dark skin tones, often in pregnancy or on birth control | Adults over 50, fair skin, a history of sunburns | Anyone; more visible in darker skin tones |
| Main trigger | Sun plus hormones, such as pregnancy or birth control pills | Years of UV exposure | Inflammation: acne, injury, irritating products |
| Does it fade by itself? | Sometimes, after pregnancy or stopping a pill; it can also last years | Not described as fading; treatment can lighten them, and they can return without sun protection | Often, within 6 to 12 months once the cause stops |

Four questions that sort most spots
- 1Is it on both sides of your face, like a mirror?Matching patches on both cheeks, or across the forehead, point toward melasma. The AAD notes it usually appears on both sides of the face.
- 2Did something happen there first?A pimple, a bug bite, a burn, a patch of eczema or a product that stung. A flat mark in that exact spot is most likely post-inflammatory hyperpigmentation.
- 3Is it small, oval and on the backs of your hands too?Separate flat spots on the hands, arms and face after years of sun, especially past 50, fit sun spots.
- 4Is it changing, growing, bleeding or turning black?Stop sorting and book a dermatologist. Cleveland Clinic warns that age spots can look like some skin cancers.
Why the difference matters
Each one responds to a different plan, and the wrong plan can make things worse. A dark mark from a breakout fades once the inflammation stops, so the job is to calm the skin and wait. Cleveland Clinic says sun spots usually need no treatment at all, and lightening them is a cosmetic choice that only holds with sun protection. Melasma is a long-term condition that a dermatologist manages, often with prescription creams. It also runs in families: in one study of 324 melasma patients cited by the AAD, 48% had a blood relative with it.
The common trap is scrubbing hard at all three. The AAD warns that irritation is itself a cause of dark spots, so an aggressive scrub or a stinging product can darken post-inflammatory marks and melasma alike.
What changes for darker skin
If you have brown or Black skin, melasma and post-breakout marks deserve the closer look. The AAD says women aged 20 to 40 with medium to dark skin tones are most likely to develop melasma, naming Latin, Asian, Black and Native American heritage, and the AAD's guide to post-inflammatory dark spots is written for darker skin tones. Sun spots, by contrast, are linked by Cleveland Clinic to fair skin, though anyone can get them.
Deep post-inflammatory color can look slate blue or gray, which can be confused with melasma's gray-brown. The AAD says that deeper color can take years to fade. That is one more reason to get a diagnosis before you pick a product.
Visible light matters too. The AAD recommends a tinted sunscreen with iron oxide for darker skin, because iron oxide blocks visible light as well as UV. Look for it in the inactive ingredients, choose SPF 30 or higher, and reapply every two hours. It helps with all three.
Often by looking, sometimes with a lamp
The AAD says a dermatologist can often diagnose melasma by examining the face and neck, and may use a Wood's lamp or a dermatoscope to see how deep the pigment goes. When a spot could be something else, a small biopsy settles it. That visit is worth more than any guess, including this guide.
Where Karisma Esthetics fits
Kay Woodson does not diagnose skin conditions. Once you know what you have, the studio's facials can fit around it. For surface marks and sun spots, the options are on the hyperpigmentation page. For melasma, start with your dermatologist and read the melasma page for why the gentle $125 Signature Facial is the one to discuss with them.
Telling dark spots apart
Is melasma a type of hyperpigmentation?
Yes. Hyperpigmentation covers any patch darker than the skin around it. Melasma, sun spots and post-inflammatory marks are three kinds, each with its own cause.
How do I know if it is melasma or sun damage?
Melasma tends to form larger, matching patches on both sides of the face. Sun spots are smaller, separate and also show up on the hands and arms. A dermatologist can confirm, sometimes with a Wood's lamp.
Why does my melasma get darker in summer?
The AAD lists melasma among summer skin problems because sun exposure makes the patches more noticeable. The AAD also names visible light as a cause of dark spots, which is why a tinted sunscreen with iron oxide helps.
How is melasma treated in Black women?
By a dermatologist, with a plan that protects the skin from irritation, since darker skin marks easily. The AAD notes melasma is more common in Black, Latin, Asian and Native American women. A tinted SPF 30 or higher with iron oxide is part of every plan.
Can sun spots turn into skin cancer?
Cleveland Clinic describes liver spots as harmless, but notes they can look like some skin cancers. See a dermatologist if a spot darkens, grows, bleeds or develops an irregular border.
