Dark patches on your face may develop after sun exposure, acne, skin irritation or hormonal changes. Melasma, tanning and post-inflammatory hyperpigmentation can look similar, but they have different patterns and may require different care. The location of the patches, when they appeared and whether they followed a breakout or rash can help a dermatologist identify the cause.
If you are considering pigmentation treatment in Egmore, understanding these differences is a useful first step towards choosing appropriate care.
Is Pigmentation Different From Melasma and Tanning?
Pigmentation refers to the colour of your skin. Melanin, the pigment produced by specialised skin cells, contributes to your natural skin tone.
When an area becomes darker than the surrounding skin, it is called hyperpigmentation. This is a broad term rather than a single diagnosis.
Melasma is one type of hyperpigmentation. Dark marks after acne or inflammation are another. Tanning is a response to ultraviolet exposure that can also darken the skin.
The important question is therefore not simply whether you have pigmentation, but what is causing it.
What Could Be Causing Your Dark Facial Patches?
1. Melasma
Melasma usually appears as flat, irregular brown or grey-brown patches. It commonly affects the cheeks, forehead, nose and upper lip, often in a similar pattern on both sides of the face.
Possible contributing factors include:
- Sun exposure
- Visible light, particularly in darker skin tones
- Pregnancy-related hormonal changes
- Certain hormonal medicines
- Family tendency
Melasma generally does not cause itching, pain or scaling. If the affected area is uncomfortable or inflamed, another condition may be present.
Although melasma may improve with treatment, it can return. Consistent protection and maintenance care are often needed.
2. Post-Inflammatory Hyperpigmentation
Post-inflammatory hyperpigmentation develops after the skin has been inflamed or injured.
Common triggers include:
- Acne
- Eczema or other rashes
- Irritation from skincare products
- Burns or abrasions
- Picking and scratching
- Reactions after unsuitable cosmetic procedures
These marks usually appear where the original inflammation occurred. For example, dark spots that remain after pimples settle may be post-acne pigmentation.
The marks can be brown, dark brown or greyish, depending partly on the depth of pigment. They may last longer in darker skin tones.
Treating the original acne, rash or irritation is essential to prevent new marks from developing.
3. Tanning
Tanning occurs when ultraviolet exposure stimulates changes in skin pigment. It may become noticeable after outdoor work, travel, sports or repeated everyday sun exposure.
Tanning often affects exposed areas more broadly, although the pattern can vary depending on clothing, shade and how sunscreen is applied.
A tan may gradually fade when exposure is reduced, but repeated exposure can maintain the darker appearance. Tanning also indicates ultraviolet exposure, so preventing further sun damage matters alongside addressing the colour change.
4. Sun Spots
Sun spots, also called solar lentigines, are individual flat brown spots associated with accumulated sun exposure.
They differ from a general tan because they usually appear as more defined spots and may remain even after surrounding tanning fades.
A dermatologist should assess a spot that is new, changing or noticeably different from your other marks before you use a pigmentation treatment on it.
5. Other Skin Conditions or Medication Effects
Not every dark facial patch is melasma, tanning or an acne mark.
Other inflammatory conditions, reactions to products and certain medicines can also cause changes in skin colour. Persistent grey-brown patches or pigmentation accompanied by itching, scaling or other symptoms may need further assessment.
Do not stop prescribed medication yourself if you suspect a connection. Discuss the timing of the pigmentation with your doctor.
How Can You Tell Whether It Is Melasma, Tanning or Acne Pigmentation?
Your history can provide clues, but appearance alone cannot reliably confirm the diagnosis.
Think About When It Started
Darkening after repeated outdoor exposure may suggest tanning. Marks following pimples or a rash may suggest post-inflammatory hyperpigmentation.
Patches appearing during pregnancy or after a hormonal change may raise the possibility of melasma.
Look at the Pattern
Melasma often produces patches on both sides of the face. Post-inflammatory pigmentation usually follows the location of earlier inflammation.
Tanning may affect exposed areas more generally, while sun spots tend to be separate, defined marks.
Notice Other Symptoms
Melasma and uncomplicated tanning are generally flat and symptom-free.
Itching, burning, scaling, pain or persistent redness may indicate an active skin condition that needs treatment before pigmentation can improve.
More than one cause can be present at the same time. You may have melasma, post-acne marks and tanning together.
Can Skincare Products Make Dark Patches Worse?
Yes. Products that irritate your skin can cause or worsen post-inflammatory pigmentation.
Potential problems include:
- Using several exfoliating acids together
- Applying strong products too frequently
- Scrubbing aggressively
- Continuing a product that causes burning or a rash
- Using unprescribed steroid-containing lightening creams
A tingling or burning sensation does not mean a product is working better. Persistent irritation can make uneven pigmentation harder to manage.
If a cosmetic product causes a reaction, stop using it and seek advice if symptoms persist.
What Can You Do About Dark Facial Patches?
Protect Your Skin From the Sun
Sun protection is a central part of managing many pigmentation concerns.
Choose a broad-spectrum sunscreen with SPF 30 or higher. Apply it adequately and reapply approximately every two hours outdoors, and after swimming or heavy sweating.
Also use shade, a wide-brimmed hat and other practical protection. Sunscreen works best alongside these measures.
Consider Tinted Sunscreen for Melasma
A tinted sunscreen containing iron oxides can provide protection against visible light, which can worsen melasma in some people.
Ask your dermatologist about a formulation that suits your skin tone, sensitivity and daily routine.
Keep Your Routine Gentle
Use a mild cleanser and a suitable moisturiser. Avoid repeatedly exfoliating or adding several brightening products at once.
A comfortable skin barrier makes it easier to follow treatment consistently.
Control Acne or Other Inflammation
If new pimples or rashes continue appearing, new dark marks may follow.
Managing the underlying condition is an important part of pigmentation treatment in Egmore, rather than treating each mark separately.
Avoid Harsh Home Remedies
Lemon juice, abrasive scrubs and household bleaching products can irritate or injure the skin. They do not offer a reliable treatment for melasma or persistent pigmentation.
Record Changes Without Checking Constantly
Photographs taken occasionally in similar lighting can help you discuss progress with your dermatologist.
Daily comparisons under different lighting can make gradual improvement difficult to judge.
What Treatment Options May Help Facial Pigmentation?
Treatment depends on the diagnosis, pigment depth, skin sensitivity and whether an active skin condition is present.
Topical Treatments
A dermatologist may recommend ingredients such as azelaic acid, selected retinoids or supervised hydroquinone-based treatment.
The choice and duration matter. Prescription lightening medicines should be used according to medical instructions, and pregnancy or breastfeeding must be discussed before treatment is selected.
Chemical Peels
Selected chemical peels may help some superficial pigmentation concerns.
However, peels are not suitable for everyone. Excessive irritation or an unsuitable peel can worsen pigmentation, particularly in skin that develops dark marks easily.
Laser and Light Procedures
Certain procedures may be considered for selected cases, but laser treatment is not automatically the best option for every dark patch.
Melasma can worsen or recur after procedures. A dermatologist should explain why a procedure is appropriate, its risks and how aftercare will be managed.
Maintenance Care
Improvement does not always mean the tendency to develop pigmentation has disappeared.
Melasma in particular may require ongoing sun protection and a maintenance plan to help preserve results.
How Long Does Pigmentation Take to Improve?
Pigmentation usually improves gradually.
The timeline depends on:
- The underlying cause
- How long the patches have been present
- Whether pigment is superficial or deeper
- Continued sun exposure
- Ongoing acne or irritation
- Treatment consistency
Some post-inflammatory marks fade over several months, while deeper pigmentation may take longer. Melasma often requires longer-term management.
Avoid expecting an immediate change or increasing treatment strength without advice.
When Should You See a Dermatologist?
Consider an assessment when:
- Dark patches persist or keep returning
- You are unsure what is causing them
- Pigmentation is spreading
- Products cause burning, redness or peeling
- New acne continues to leave marks
- Pigmentation develops after a procedure
- The appearance affects your confidence
Seek prompt assessment for a spot that changes in size, shape or colour, develops irregular borders, bleeds or does not heal. Such changes should be examined rather than treated as routine pigmentation.

Frequently Asked Questions
Is every dark patch on the face melasma?
No. Dark patches can also result from acne, irritation, sun exposure, medicines or other skin conditions. A dermatologist can help distinguish them.
Can tanning turn into melasma?
Tanning and melasma are different responses, although sun exposure can worsen melasma in someone who is susceptible. They can also occur together.
Why do pimples leave dark marks?
Inflammation from acne can stimulate excess pigment production. Picking or irritating the area may increase the likelihood of persistent marks.
Can melasma disappear permanently?
Melasma may improve substantially, but recurrence is possible. Long-term sun protection and maintenance care may be needed.
Will sunscreen remove existing pigmentation?
Sunscreen does not directly remove all existing pigment. It helps prevent further darkening and supports the results of other treatment.
Is laser treatment necessary for pigmentation?
No. Many people are managed with sun protection, topical treatment and control of underlying inflammation. Procedures are considered according to the diagnosis.
Can I treat pigmentation during pregnancy?
Some approaches may be suitable, but several common pigmentation medicines are avoided during pregnancy. Tell your dermatologist that you are pregnant or planning pregnancy before starting treatment.
