Pigmentation & Melasma: Causes and How to Treat Dark Patches

Dark spots, patchy tanning, and melasma are among the most common — and most frustrating — skin concerns in India, partly because strong sun and heat make them worse and prone to coming back. The most important thing to know: pigmentation is manageable, but it needs the right diagnosis and consistency, not quick fixes. At Dermacare in Himayat Nagar, Hyderabad, here’s how we approach it.

What causes pigmentation?

Pigmentation is caused by excess melanin, the pigment that gives skin its colour. The main triggers are:

• Sun exposure (UV): the number-one cause and the main reason pigmentation returns.
• Hormones: pregnancy (“mask of pregnancy”), birth control pills, and hormonal shifts drive melasma.
• Inflammation: acne, injuries, and irritation leave dark marks (post-inflammatory hyperpigmentation).
• Heat: even without direct sun, heat can worsen melasma — relevant in Hyderabad’s climate.
• Harsh products and over-treatment: irritation can paradoxically worsen pigmentation.
• Genetics: a family tendency toward melasma and easy tanning.

Common types of pigmentation

Type	What it looks like	Common trigger
Melasma	Symmetrical brown patches on cheeks, forehead, upper lip	Hormones + sun + heat
Post-inflammatory (PIH)	Dark marks where acne or injury healed	Inflammation
Sun spots / uneven tan	Diffuse darkening and blotchy tone on exposed skin	UV exposure
Tanning	Overall darkening of exposed areas	Sun

Melasma is the most stubborn type. It can be improved and controlled, but it tends to recur — which is why maintenance and sun protection are non-negotiable.

How pigmentation is treated

1. Sun protection (the foundation — non-negotiable)

No pigmentation treatment works without it. Use a broad-spectrum sunscreen (SPF 30–50) every day, reapply through the day, and add hats and shade. In many cases, disciplined sun protection alone produces visible improvement — and it prevents pigmentation from coming back after treatment.

2. Brightening actives

Dermatologist-guided topical ingredients help fade pigment over time — options include vitamin C, niacinamide, azelaic acid, kojic acid, and prescription formulas where appropriate. These are used carefully, because overuse and irritation can worsen pigmentation.

3. In-clinic treatments

• Chemical peels: exfoliate and lighten pigment gradually over a series of sessions.
• Laser and light-based treatments: target pigment for certain types — used cautiously in melasma, as the wrong settings can aggravate it.
• Combination protocols: most real-world results come from combining sunscreen, topicals, and gentle procedures under supervision.

Because melasma is easily aggravated, professional guidance matters more here than with almost any other skin concern — aggressive or unsupervised treatment often backfires.

Why pigmentation comes back (and how to prevent it)

Pigmentation, especially melasma, is a chronic tendency rather than a one-time problem. It returns when sun protection lapses, hormones shift, or the skin is irritated. To keep results:

• Wear sunscreen every single day, indoors near windows too.
• Continue a gentle maintenance routine as advised.
• Avoid harsh scrubs, unregulated “whitening” creams (some contain harmful steroids), and DIY acids.
• Treat acne early to prevent dark marks — see our acne and acne scars guide.

Frequently asked questions about pigmentation & melasma

Can pigmentation be removed permanently?

Many types of pigmentation can be significantly faded, but melasma in particular is a recurring condition rather than something “cured” once. With consistent sun protection and maintenance, results can be kept for the long term, but lapses often bring it back.

What is the best treatment for melasma?

There’s no single best treatment — the most effective approach combines strict daily sunscreen, dermatologist-guided brightening actives, and gentle procedures like peels, chosen for your skin. Melasma is easily aggravated, so treatment should be supervised rather than aggressive.

Does sunscreen really help pigmentation?

Yes — it’s the single most important step. UV is the main trigger for pigmentation and the main reason it returns, so daily broad-spectrum sunscreen both improves existing pigmentation and protects your results after treatment.

Are fairness or skin-whitening creams safe for dark spots?

Many over-the-counter “fairness” creams are unregulated and can contain harmful ingredients like strong steroids that damage skin and worsen pigmentation long-term. It’s safer to use dermatologist-prescribed brightening treatment.

How long does pigmentation treatment take to show results?

Pigmentation fades gradually — usually over several weeks to a few months of consistent treatment, depending on the type and depth. Melasma and deeper pigment take longer and need ongoing maintenance.

Why does my melasma keep coming back?

Melasma recurs because its triggers — sun, heat, and hormones — are ongoing. Skipping sunscreen, hormonal changes, and skin irritation all bring it back, which is why daily protection and maintenance are essential.
