Black Patches on Face: Causes, Symptoms & Best Treatment Options (Dermatologist Guide)
Black patches on the face are one of the most common skin complaints seen in dermatology clinics. These dark areas can appear suddenly or slowly increase over time, affecting confidence and making the skin look uneven.
In most cases, black patches are caused by hyperpigmentation (excess melanin production). However, the exact reason can vary — and the best treatment depends on identifying the correct cause.
This blog explains the top causes, symptoms, and dermatologist-recommended treatments for black patches on the face.

1.Increased melanin production
2.Skin inflammation or irritation
3.Hormonal changes
4.Sun damage
5.Certain medical conditions
They may appear as:
•Brown patches
•Grey-brown pigmentation
•Dark uneven areas
•Patchy discoloration
Where Do Black Patches Commonly Appear?

1.Cheeks
2.Forehead
3.Upper lip

Top Causes of Black Patches on Face
1) Melasma (Most Common Cause)
Melasma causes brown to grey-brown patches, especially on:
1.Cheeks
2.Forehead
3.Upper lip
Common triggers:
1.Sun exposure
2.Pregnancy
3.PCOS and hormonal imbalance
4.Birth control pills
5.Thyroid disorders
6.Genetic tendency
Melasma is very common in Indian skin types.
2) Post-Inflammatory Hyperpigmentation (PIH)
PIH means dark patches left behind after skin inflammation.
It commonly happens after:
1.Acne and pimples
2.Scratching or rubbing
3.Allergic reactions
4.Burns
5.Waxing or threading
6.Skin irritation from products
3) Sun Damage and Tanning
Sun exposure is one of the biggest reasons for facial pigmentation.
It can cause:
1.Uneven skin tone
2.Dark patches on cheeks
3.Sun spots
4.Worsening of melasma
Even 10–15 minutes of daily sun exposure without sunscreen can worsen pigmentation.
4) Acanthosis Nigricans (Dark Thick Patches)
This condition causes dark, thick, velvety patches, usually on:
1.Neck
2.Underarms
3.Groin
4.Sometimes cheeks and jawline
It is often linked to:
1.Insulin resistance
2.Obesity
3.Diabetes / Prediabetes
4.PCOS
5) Fungal Infection (Sometimes)
Some fungal infections can cause dark patches, especially if you notice:
1.Mild itching
2.Fine scaling
3.Slow spreading
6) Cosmetic Allergy / Contact Dermatitis
Pigmentation may develop due to irritation from:
1.Face bleach
2.Hair dye
3.Perfumes
4.Certain makeup products
5.Harsh soaps
6.Fairness creams
Many “fairness” creams contain hidden steroids, which worsen pigmentation over time.
7) Other Skin Conditions (Less Common)
In some cases, black patches can be caused by:
1.Lichen planus pigmentosus
2.Vitamin B12 deficiency
3.Addison’s disease (rare)
4.Drug-induced pigmentation

How Dermatologists Diagnose Black Patches on Face
A dermatologist may diagnose pigmentation by:

4.Checking for hormonal imbalance or PCOS symptoms
5.Blood tests (only if needed)
6) Best Treatment Options for Black Patches on Face
Treatment depends on the cause, skin type, and depth of pigmentation.
1) Sunscreen (Most Important Treatment Step)
If you want pigmentation to reduce, sunscreen is non-negotiable.
A good sunscreen should be:
1.SPF 50
2.PA+++ or PA++++
3.Broad spectrum (UVA + UVB)
4.Gel-based for oily skin / cream-based for dry skin
How to use:
1.Apply every morning
2.Reapply every 3–4 hours if outdoors
3.Use even indoors (especially if near windows)
2) Dermatologist-Prescribed Creams
Depending on the cause, dermatologists may prescribe:
1.Vitamin C
2.Niacinamide
3.Azelaic acid
4.Kojic acid
5.Tranexamic acid (topical)
6.Retinoids (tretinoin)
7.Hydroquinone (short-term and monitored)
Avoid self-medicating with hydroquinone or steroid creams.
3) Oral Medicines (In Selected Cases)
Some patients may need oral treatment, especially for melasma.
A dermatologist may prescribe:
1.Oral tranexamic acid (only under supervision)
2.Antioxidants
3.Vitamin correction (B12, D, etc.)
4) Chemical Peels for Pigmentation
Chemical peels are highly effective for:
1.Melasma (selected cases)
2.Sun tanning
3.Acne marks
4.Uneven pigmentation
Common peels include:
1.Glycolic peel
2.Lactic peel
3.Salicylic peel
4.Mandelic peel
5.TCA peel (selected cases)
5) Laser Treatment for Pigmentation
Laser and light-based treatments can help in:
1.Sun spots
2.Certain pigmentation types
3.Resistant melasma (very carefully)
Wrong lasers can worsen pigmentation in Indian skin. Always choose an experienced dermatologist.
6) Microneedling + Depigmentation Serums
Microneedling may help with:
1.Post-acne pigmentation
2.Skin texture
3.Mild melasma
It is done in multiple sessions.
How Long Does It Take to Treat Black Patches on Face?
This depends on the cause:
1.PIH (acne marks): 6–12 weeks
2.Sun tanning: 4–8 weeks
3.Melasma: 3–6 months (sometimes longer)
4.Acanthosis nigricans: depends on insulin resistance control
Pigmentation treatment is slow — but very rewarding when done correctly.
