Dark spots on the face can be frustrating, especially when they seem to appear despite having a good skincare routine.
But not all pigmentation is the same.
Dark patches can develop from sun exposure, hormonal changes, acne, inflammation, ageing and other skin triggers. Understanding what is causing the pigmentation is an important first step in choosing the right treatment.
At LunaSkin in East Auckland, we assess your individual skin condition and pigmentation concerns before recommending a suitable treatment approach.
In this guide, we’ll explain the difference between sun spots, melasma and acne marks, what causes them and what you can do to improve uneven skin tone.
What Causes Dark Spots on the Face?
Dark spots generally occur when the skin produces more melanin than usual in a particular area.
Melanin is the natural pigment responsible for your skin colour. When pigment production becomes uneven, darker areas can develop.
Common causes of facial pigmentation include:
- Sun exposure
- Hormonal changes
- Acne and inflammation
- Skin irritation
- Ageing
- Skin injuries
- Certain medications or hormonal influences
- Genetic tendency towards pigmentation
Sun exposure is one of the most important factors to consider when managing pigmentation. Regular UV exposure can make existing pigmentation more noticeable and contribute to new pigmentation developing.
The key question is: what type of pigmentation do you have?
Sun Spots vs Melasma vs Acne Marks
Although sun spots, melasma and acne marks can look similar, they have different causes and appearances.
1. Sun Spots
Sun spots, sometimes called age spots or solar lentigines, are commonly associated with cumulative sun exposure.
They often appear on areas that receive regular UV exposure, such as:
- Face
- Forehead
- Cheeks
- Nose
- Hands
- Décolletage
Sun spots are usually individual brown or darker areas that become more noticeable over time.
If you’ve experienced significant sun exposure over the years, you may gradually notice more uneven pigmentation.
2. Melasma
Melasma usually appears as larger, irregular brown or grey-brown patches.
It commonly affects:
- Cheeks
- Forehead
- Upper lip
- Nose
- Chin
Hormonal changes and UV exposure can contribute to melasma.
Unlike an individual sun spot, melasma can affect larger areas of the face and may require a carefully managed treatment and skincare plan.
If you think you may have melasma, read our guide to Melasma Treatment Auckland for more information.
3. Acne Marks
Dark marks left behind after acne are often called post-inflammatory hyperpigmentation.
They can develop after:
- Pimples
- Cystic acne
- Picking or squeezing spots
- Inflammation
- Acne-related irritation
These dark marks aren’t necessarily permanent acne scars.
In many cases, the acne has healed but leaves behind temporary pigmentation that gradually becomes lighter.
However, persistent acne pigmentation can benefit from a targeted skincare and professional treatment plan.
How Can You Tell What Type of Pigmentation You Have?
It isn’t always possible to accurately identify pigmentation simply by looking in the mirror.
For example:
Small brown spots on sun-exposed areas may be sun-related pigmentation.
Larger patches across both cheeks may be associated with melasma.
Dark marks appearing where previous pimples healed may be post-inflammatory pigmentation.
Some people can also have more than one type of pigmentation at the same time.
This is why a professional skin consultation can be useful before choosing a treatment.
At LunaSkin, pigmentation treatments are tailored according to your individual skin condition, pigmentation type and skin tone.
What Is the Best Treatment for Dark Spots?
There isn’t one treatment that is automatically best for every type of pigmentation.
Depending on your skin and pigmentation concern, professional treatment options may include chemical peels, laser-based treatments, depigmentation treatments, microdermabrasion and professional skincare.
Chemical Peels
Chemical peels can help improve uneven skin tone, dullness and certain pigmentation concerns by exfoliating the skin and supporting skin renewal.
The type and strength of peel can be selected according to your individual skin condition.

Pigmentation Laser Treatments
Certain laser technologies can be used for specific pigmentation concerns.
LunaSkin offers several pigmentation treatment technologies, including EnLighten Pico Laser, Q-Switch Nd:YAG and Candela GentleLASE IPL, depending on the individual’s skin and pigmentation.
The appropriate treatment should always be determined following a professional assessment.
Depigmentation Treatments
Professional depigmentation treatments may be suitable for certain pigmentation concerns.
These treatments require appropriate assessment and careful aftercare to help minimise irritation and support the skin during the treatment process.
Microdermabrasion
Microdermabrasion gently exfoliates the surface of the skin and can be included as part of a broader skin rejuvenation plan.
It may help improve the appearance of dullness, uneven texture and some superficial pigmentation concerns.
Professional Skincare
Professional skincare can also play an important role in managing pigmentation.
Depending on your skin, a therapist may recommend products containing ingredients that support brighter, more even-looking skin.
The goal isn’t simply to make the skin lighter.
The goal is to help improve uneven pigmentation while maintaining healthy skin.
Can Dark Spots Be Prevented?
While not all pigmentation can be prevented, good skincare habits can help reduce the risk of pigmentation becoming worse.
1. Use Sunscreen Every Day
Daily sun protection is one of the most important habits when managing pigmentation.
Use a broad-spectrum sunscreen consistently, particularly when spending time outdoors.
Don’t rely on sunscreen only during summer.
UV exposure can occur throughout the year, even when the weather doesn’t feel particularly sunny.
2. Avoid Picking Your Acne
Picking or squeezing pimples can increase inflammation and increase the likelihood of dark marks developing afterwards.
If you regularly experience acne pigmentation, treating the underlying acne is just as important as treating the marks it leaves behind.
3. Don’t Over-Exfoliate
Using more exfoliating products doesn’t necessarily mean you’ll get faster results.
Too many acids, scrubs or active ingredients can irritate the skin.
Skin irritation can make pigmentation concerns more difficult to manage.
A consistent skincare routine is generally better than constantly changing products.
4. Treat the Cause — Not Just the Pigmentation
If pigmentation continues to return, treating the visible dark spots alone may not be enough.
For example:
- Ongoing acne can create new pigmentation.
- Sun exposure can encourage pigmentation to return.
- Hormonal changes can affect melasma.
- Skin irritation can contribute to post-inflammatory pigmentation.
A good pigmentation strategy should therefore consider why the pigmentation developed in the first place.
How Long Does Pigmentation Treatment Take?
Pigmentation doesn’t usually disappear overnight.
The timeline depends on several factors, including:
- Type of pigmentation
- Depth of pigmentation
- Skin tone
- Treatment selected
- Number of treatments
- Home skincare routine
- Sun exposure
- Individual response
Some pigmentation concerns may improve gradually over a series of treatments rather than after one appointment.
It’s also important to understand that certain pigmentation concerns, particularly melasma, can return.
The goal is often long-term management and improvement, rather than promising that pigmentation will never come back.
Why Does Pigmentation Keep Coming Back?
One of the most frustrating things about pigmentation is seeing it improve and then gradually return.
This can happen when the underlying trigger hasn’t changed.
Pigmentation may become more noticeable again following:
- Significant sun exposure
- Inconsistent sunscreen use
- Hormonal changes
- Acne breakouts
- Skin inflammation
- Irritation from unsuitable skincare
This is why sun protection and an appropriate maintenance skincare routine are important even after professional treatment.
When Should You See a Skin Professional?
Consider having your skin professionally assessed if:
- You have persistent dark patches.
- Your pigmentation is spreading.
- You’re unsure whether you have melasma or sun spots.
- Acne has left widespread dark marks.
- Over-the-counter products haven’t helped.
- Your skin has become sensitive from using multiple active ingredients.
- You’re considering laser or professional peeling treatments.
A professional assessment can help determine what may be contributing to your pigmentation and which treatment options may be appropriate.
Dark Spots on the Face: Which Treatment Is Right for You?
The most important thing to remember is that pigmentation isn’t one single skin concern.
Sun spots, melasma and acne marks can look similar, but they can have different causes and may respond differently to treatment.
At LunaSkin in East Auckland, pigmentation treatments are customised according to your skin tone, pigmentation type and overall skin condition.
Professional treatment options may include chemical peels, laser-based treatments, depigmentation treatments, microdermabrasion and professional skincare.
If you’re unsure what is causing your dark spots, a skin consultation can be a useful first step.

Can chemical peels help dark spots?
Chemical peels may help improve the appearance of uneven skin tone and certain pigmentation concerns. The appropriate peel depends on your skin condition and pigmentation.
Does sunscreen help prevent pigmentation?
Consistent sun protection is an important part of managing pigmentation and reducing additional UV-related pigmentation.
Can pigmentation be completely removed?
Results vary depending on the type and cause of pigmentation. Some pigmentation can be significantly improved, but concerns such as melasma may require ongoing management.
How do I know which pigmentation treatment is right for me?
A professional skin assessment can help determine the type of pigmentation you’re experiencing and which treatment approach may be appropriate for your skin.
