Melasma vs. Sun Damage: How to Tell the Difference
Melasma vs. Sun Damage: They May Look Similar, But Treatment Can Be Very Different
You look in the mirror and notice brown patches across your cheeks. Maybe there's discoloration along your forehead, upper lip or jawline. Your first thought might be:
"It's probably sun damage."
Or maybe you've heard enough about pigmentation on social media that you immediately assume it's melasma.
The problem is that melasma and sun-related pigmentation can sometimes look similar, but they don't necessarily behave the same way.
That distinction becomes especially important when choosing an aesthetic treatment.
A treatment that can be effective for certain types of sun damage, such as IPL, may not be appropriate for someone with melasma. Heat, light and inflammation can potentially trigger or worsen melasma in some people.
At Glow Med Spa in Camas, WA, we believe pigmentation should be evaluated before simply trying to erase every brown spot.
Here's what you should know.
What Is Sun Damage?
"Sun damage" is a broad term describing changes in the skin associated with cumulative exposure to ultraviolet radiation.
Your skin remembers those afternoons at the beach, years of driving without sunscreen, outdoor activities and all the times sunscreen wasn't reapplied.
Over time, UV exposure can contribute to visible changes including:
Freckles
Solar lentigines, commonly called sun spots or age spots
Uneven pigmentation
Rough texture
Fine lines
Loss of elasticity
Redness and visible vessels
Other signs of photoaging
Sun-related pigmentation often becomes more noticeable as we age because UV exposure accumulates over a lifetime.
What Do Sun Spots Look Like?
Sun spots, or solar lentigines, commonly appear as distinct areas of tan to dark-brown pigmentation.
They frequently develop on areas that receive significant sun exposure, including the:
Face
Cheeks
Forehead
Hands
Arms
Shoulders
Décolletage
They may appear more like individual spots or scattered areas of pigmentation rather than the broader, symmetrical patches often associated with melasma.
However, appearance alone isn't enough to diagnose every brown spot.
Any lesion that is new, changing, irregular, bleeding, itching or otherwise concerning should be evaluated medically before receiving an aesthetic pigmentation treatment.
What Is Melasma?
Melasma is an acquired pigmentation disorder characterized by patches of increased pigmentation, most commonly on the face.
It frequently appears on the:
Cheeks
Forehead
Upper lip
Bridge of the nose
Chin
Jawline
Unlike a single sun spot, melasma often appears as larger patches or areas of pigmentation.
It may also occur relatively symmetrically, meaning similar areas appear on both sides of the face.
What Causes Melasma?
Melasma is complicated because it isn't caused by just one thing.
Several factors may contribute to its development or recurrence, including:
Hormonal influences
Melasma is commonly associated with hormonal changes, including pregnancy and certain hormonal medications.
This is one reason it has sometimes been called the "mask of pregnancy."
UV exposure
Ultraviolet exposure can trigger melanin production and make melasma more noticeable.
Visible light
Research has also implicated visible light in melasma, particularly in individuals with darker skin phototypes.
Heat
Heat may aggravate melasma in some people, which is one reason treatment selection deserves careful consideration.
Genetics
Some people simply have a greater predisposition toward developing melasma.
And here's one of the frustrating things about it:
You can successfully improve the appearance of melasma and still experience recurrence.
For many people, melasma is better thought of as something that requires ongoing management rather than a pigmentation problem that can simply be permanently "removed."
Melasma vs. Sun Damage: What's the Difference?
Although both can create brown pigmentation, there are some general patterns.

These are patterns, not a diagnostic test.
Someone can also have both melasma and sun damage at the same time.
That's one reason pigmentation can be tricky.
Why Correctly Identifying Pigmentation Matters
Imagine treating every brown spot exactly the same way.
If it's a solar lentigo, one treatment strategy may make sense.
If it's melasma, that same approach could potentially make the pigmentation more noticeable.
If it's post-inflammatory hyperpigmentation, there may be an entirely different trigger.
And if the spot is actually a suspicious skin lesion, it shouldn't be treated cosmetically at all until it has been medically evaluated.
This is why we don't believe pigmentation treatment should begin with:
"Let's just laser it."
It should begin with:
"What are we actually looking at?"
Why IPL Can Be Great for Sun Damage
IPL stands for Intense Pulsed Light.
Although people often refer to IPL as a laser, technically it uses broad-spectrum light rather than a single laser wavelength.
IPL can target chromophores within the skin, including melanin associated with certain pigmented lesions.
For appropriately selected clients, IPL may help improve the appearance of:
Sun spots
Freckles
Uneven pigmentation
Certain redness concerns
Overall signs of photodamage
After treatment, some pigmented areas may temporarily darken before gradually flaking or fading.
But this is where the distinction between sun damage and melasma becomes extremely important.
Why We Avoid IPL for Melasma
It can be tempting to think:
"If light can target brown pigment, why wouldn't IPL work for melasma?"
Because melasma isn't simply a collection of isolated brown spots.
It's a complex and reactive pigment disorder.
Heat, light and inflammation may stimulate melanogenesis and potentially trigger worsening or rebound pigmentation in susceptible individuals.
Some published research has explored light and laser therapies for melasma, including combination approaches. However, recurrence and post-inflammatory pigment changes remain concerns.
For that reason, at Glow Med Spa we do not use IPL as our go-to treatment for melasma.
If we suspect melasma, we're going to take a more conservative approach rather than risk aggravating the condition.
So What Do We Use for Melasma?
Melasma treatment generally requires a multi-pronged approach.
Depending on the client, treatment planning may include professional skincare, carefully selected chemical peels, microneedling and diligent photoprotection.
Chemical Peels
Certain chemical peels may be incorporated into a melasma-management plan.
The objective isn't to aggressively strip away pigmentation.
In fact, excessive inflammation may make pigment problems worse.
Instead, the peel and treatment intensity should be selected thoughtfully based on the individual's skin.
Microneedling
Microneedling may also be considered as part of a comprehensive approach to melasma.
It creates controlled microchannels within the skin without relying on the same light-based mechanism as IPL.
Treatment should still be appropriately selected and performed conservatively because inflammation itself can influence pigmentation.
Professional Skincare
What happens at home matters enormously.
A melasma plan may include ingredients selected to help address excess pigmentation and support healthy skin turnover.
Depending on the individual and appropriate professional guidance, pigment-focused skincare may incorporate ingredients such as:
Tranexamic acid
Vitamin C
Retinoids or retinol
Azelaic acid
Niacinamide
Other brightening ingredients
Prescription treatments may also be appropriate for some patients and should be managed by a qualified medical provider.
Sunscreen Is Part of the Treatment
You cannot have a serious conversation about melasma or sun damage without talking about sun protection.
Daily broad-spectrum sunscreen is essential.
And not just when you're going to the beach.
UV exposure happens while you're driving, walking the dog, sitting near windows and going about everyday life.
For melasma-prone individuals, tinted sunscreen containing iron oxides may also be worth discussing because iron oxides can provide additional protection against visible light.
Hats, shade and other physical sun-protection strategies can also make a meaningful difference.
If we're trying to reduce pigmentation while the skin is repeatedly being stimulated by light exposure, we're fighting an uphill battle.
What About Melasma on the Upper Lip?
This is an especially frustrating area for many clients.
Melasma above the lip can create a shadow-like appearance that some people mistake for hair growth.
Trying to aggressively exfoliate, scrub or repeatedly treat the area without understanding what's causing the pigmentation may irritate the skin further.
A pigment-management strategy is usually much more appropriate than simply attacking the area.
Can Hormones Cause Melasma?
Hormonal changes are strongly associated with melasma.
Pregnancy is one of the best-known examples, but hormonal medications and other hormonal influences may also play a role.
That doesn't mean everyone with melasma has a hormonal imbalance.
It means hormones are one of several recognized factors that can influence the condition.
Can Melasma Go Away Permanently?
Sometimes melasma fades considerably, particularly if a triggering hormonal influence changes.
However, recurrence is common.
That's why we prefer to set realistic expectations.
Our goal is to improve and manage the appearance of melasma, reduce known triggers where possible and establish a skincare strategy that supports long-term pigment control.
We don't promise that melasma will never return.
Can Sun Damage Come Back After Treatment?
The pigment we successfully treat may improve, but treatment doesn't make your skin immune to future UV exposure.
New photodamage can accumulate.
Think of aesthetic treatment as correcting some of the visible effects of previous exposure.
Sunscreen and sun-protective habits help protect that investment moving forward.
Is Every Brown Spot Safe to Treat?
No.
This is extremely important.
Aesthetic providers shouldn't simply assume that every brown lesion is cosmetic pigmentation.
If a spot is suspicious, changing or outside what we are comfortable treating aesthetically, we may recommend evaluation by a dermatologist or other qualified medical professional before proceeding.
It's better to delay a cosmetic treatment than to treat something that should have been medically evaluated.
What If I Have Both Melasma and Sun Damage?
You absolutely can.
A person may have diffuse melasma across the cheeks while also having distinct solar lentigines from years of sun exposure.
This is where treatment planning becomes more nuanced.
We have to consider the entire pigment pattern rather than treating every brown area independently.
The presence of melasma may influence which technologies we choose even when some sun damage is also present.
How Do I Know Which One I Have?
Instead of diagnosing yourself from photos online, start with a professional skin assessment.
We look at things like:
Distribution of pigmentation
Symmetry
Color
Pattern
Skin type
Sun exposure history
Hormonal history
Previous treatments
How the pigmentation behaves over time
Sometimes we'll recommend medical evaluation before aesthetic treatment.
The goal isn't just to name the pigment.
It's to determine what we can safely and realistically do about it.
Melasma vs. Sun Damage FAQs
Is melasma caused by the sun?
UV exposure is an important trigger, but melasma is more complex than ordinary sun damage. Hormones, genetics, visible light and other factors can contribute.
Are age spots melasma?
No. Solar lentigines, commonly called age spots or sun spots, are different from melasma.
Can IPL remove sun spots?
IPL may significantly improve the appearance of certain sun-related pigmented lesions in appropriately selected clients.
Can IPL make melasma worse?
Melasma can be aggravated by heat, light and inflammation, which is why IPL is generally not our preferred treatment for melasma at Glow Med Spa.
Are chemical peels good for melasma?
Carefully selected chemical peels may be incorporated into a melasma-management plan. Aggressive treatment isn't necessarily better because excessive inflammation can potentially worsen pigmentation.
Is microneedling good for melasma?
Microneedling may be considered for some clients as part of a comprehensive treatment strategy. Appropriate technique and client selection are important.
Does melasma always look symmetrical?
Symmetrical facial pigmentation is characteristic of melasma, but real-world presentations vary. Pattern alone shouldn't be used to self-diagnose.
Can I have melasma and sun damage?
Yes. It's possible to have multiple forms of pigmentation simultaneously.
Don't Treat Pigment Until You Understand the Pigment
Brown spots aren't all created equal.
Sun damage may respond beautifully to a treatment that we would deliberately avoid in someone with melasma.
That's why the question shouldn't simply be:
"How do I get rid of these brown spots?"
The better question is:
"What's causing this pigmentation, and what is the safest way to improve it?"
At Glow Med Spa in Camas, WA, we take the time to evaluate your skin before recommending a pigmentation treatment.
For sun-related pigmentation, options may include IPL, chemical peels, professional skincare and other skin-rejuvenation treatments.
When melasma is suspected, we take a more conservative approach and may consider options such as carefully selected chemical peels, microneedling, professional pigment-focused skincare and diligent sun protection while avoiding IPL as our primary treatment.
