TL;DR
Melasma shows up as symmetric, blotchy patches on the cheeks, forehead or upper lip, driven by hormones and light. Sun spots are smaller, sharply defined and scattered on areas with years of sun exposure. They need different treatment, and any spot that is changing, raised or bleeding needs an in-person exam.
Melasma vs sun spots is one of the most common mix-ups in skincare, and getting it wrong means using the wrong treatment, sometimes for years.
The short version: sun spots are small, defined, sun-damage marks. Melasma is a larger, patchy, hormone-and-light condition that behaves very differently.
Melasma vs sun spots: the short answer
If you have a few well-defined brown spots on your hands, chest and cheeks that have been slowly appearing for years, they are probably sun spots (solar lentigines). If you have symmetrical cloud-like patches on your face that darken in summer and may have started during pregnancy or after starting birth control, that points to melasma.
Many people have both at once, which is part of the confusion.
How do melasma and sun spots compare side by side?
| Feature | Melasma | Sun spots (solar lentigines) |
|---|---|---|
| Shape | Large, irregular, blotchy patches | Small, round or oval, sharp edges |
| Pattern | Symmetrical, often mirrors on both cheeks | Scattered, not symmetrical |
| Where | Cheeks, forehead, upper lip, nose bridge, jawline | Face, hands, chest, shoulders, forearms |
| Triggers | Hormones, UV and visible light, heat | Cumulative sun exposure over years |
| Seasonal change | Darker in summer, can fade in winter | Stay about the same all year |
| Typical age | 20s to 40s, more common in women | 40s and older |
| Best treatment | Pigment-suppressing creams, sunscreen, sometimes oral options | Laser, IPL, cryotherapy, topical retinoids |
| Risk if treated wrong | Heat and lasers can worsen it | Creams alone rarely clear them |
What does melasma look like?
Melasma appears as flat tan, brown or gray-brown patches with uneven, map-like borders. It tends to show up in the same places on both sides of the face, often in a "mask" pattern.
- Common on cheeks, forehead, bridge of the nose and upper lip.
- Triggered or worsened by sun, heat and hormonal shifts like pregnancy or birth control.
- More common in medium to deeper skin tones, though anyone can get it.

What do sun spots look like?
Sun spots are small, flat, well-defined patches, usually tan to brown, that appear on skin that has had years of sun exposure. They do not fade in winter, and they are not tied to hormones.
- Each spot is distinct and usually a few millimeters to a centimeter.
- They often appear first on the backs of hands and the face.
- They are harmless in themselves but can be mistaken for lookalikes that are not.
Why does the difference matter for treatment?
Because the treatments are almost opposite. Sun spots respond well to heat-based and freezing treatments (laser, IPL, cryotherapy), which can make melasma darker. Melasma responds best to pigment-suppressing creams and strict light protection, which often do little for isolated sun spots.
A realistic example: someone with cheek melasma has IPL at a spa to "fix their sun spots." The spots lighten, but the melasma comes back darker within weeks. That is a classic outcome.

How are sun spots and melasma treated differently in practice?
- Sun spots: a dermatologist may use cryotherapy (liquid nitrogen), a laser, IPL, or prescription retinoid and bleaching creams over many months. Treatment is often a one-off for each spot.
- Melasma: a prescription cream such as hydroquinone with tretinoin, strict tinted mineral sunscreen, and sometimes oral options like tranexamic acid. Treatment is ongoing.
If you have both, a sensible order is melasma cream first, sun spots later, with a clinician choosing the least heat-based method.
Can you prevent either?
Partly. Daily sunscreen reduces new sun spots and slows melasma, but it will not remove a hormonal tendency. Hats, shade and avoiding peak sun help both, and tinted iron-oxide sunscreen is the better pick for melasma. See visible light and melasma.
For anyone with deeper skin, the stakes are higher: a heat-based treatment aimed at a harmless sun spot can leave a new dark mark, so ask for a patch test first.
Can you have both?
Yes, and it is common. If you have both, treat melasma with creams first and consult a dermatologist before using any light-based treatment on sun spots nearby.
What are the common mistakes with each?
- Using strong peels or scrubs on melasma to "buff it off."
- Expecting a cream to erase a distinct sun spot.
- Booking IPL for all brown marks on the face without a diagnosis.
- Ignoring a single dark spot that looks different from the others.
What if I am not sure which one I have?
- Take photos in the same light every few weeks. Melasma changes with seasons and hormones, sun spots do not.
- Think about timing: did patches start during pregnancy, after birth control, or in a hot summer?
- Look at symmetry: mirror-image patches suggest melasma.
- Ask a doctor, especially if the diagnosis changes your treatment.
You may also see "hyperpigmentation" used as an umbrella term. Melasma and sun spots are both types of it, but each is treated differently. For the melasma side, read melasma vs hyperpigmentation.
What if the spot might be something else?
Not every brown mark is harmless. See a doctor in person promptly if a spot:
- Is raised, rough, bleeding or crusting.
- Has uneven color, irregular borders or is growing.
- Is changing in size, shape or color.
- Is a single dark spot unlike the others.
Skin cancer lookalikes such as lentigo maligna can resemble a sun spot on the face. A clinician can check it with a dermatoscope and, if needed, a biopsy. Online care is not a substitute for that exam. The American Academy of Dermatology has helpful melasma information as well.

How can I tell melasma from sun spots?
Melasma forms symmetric, blotchy patches and changes with seasons or hormones. Sun spots are small, sharply defined, scattered and stay the same year-round.
Can sun spots turn into melasma?
No, they are separate conditions, but you can have both. Sun exposure contributes to each.
Will melasma treatment remove sun spots?
Usually not. Sun spots tend to respond to lasers, IPL or cryotherapy, which can worsen nearby melasma.
Can a dermatologist tell the difference?
Yes, often by look and pattern, sometimes with a Wood's lamp or dermatoscope. See one in person if you are unsure or a spot is changing.
Does sunscreen help both?
Yes. Daily sunscreen prevents new sun spots and is essential for keeping melasma from darkening, ideally a tinted mineral formula.
