What is pigmentation?
Your skin gets its colour from melanin, a pigment made by cells called melanocytes. When these cells make too much melanin in one area, that patch looks darker than the skin around it. Doctors call this hyperpigmentation.
It isn't one single condition. The most common types are:
- Melasma: brown or grey-brown patches, usually on the cheeks, forehead, nose and upper lip. It's more common in women and in people with medium to darker skin tones.
- Post-inflammatory hyperpigmentation (PIH): dark marks left behind after skin has been inflamed or injured, for example by acne, eczema, a burn or a cosmetic procedure.
- Sun spots and tanning: darker areas caused by repeated sun exposure over time.
- Uneven tone and dullness: a general patchiness that makes skin look less clear and bright.
Pigmentation is usually harmless. But it can affect how people feel about their skin, and some types, especially melasma, can come back if they're not managed well.
What causes pigmentation?
Anything that tells your melanocytes to work harder can lead to pigmentation. Common triggers include:
- Sun exposure: UV rays, and visible light in deeper skin tones, are the biggest everyday trigger. They can start pigmentation and make existing patches darker.
- Hormones: pregnancy and birth control pills are well-known melasma triggers.
- Inflammation: acne, rashes, insect bites, picking at skin or an aggressive treatment can all leave dark marks behind.
- Medicines and medical conditions: some medicines and health conditions are linked to pigmentation.
- Stress and genetics: melasma often runs in families, and stress may play a part.
- Harsh products: irritating skincare, waxing or scrubbing can inflame skin and make some pigmentation worse.
People with medium to dark skin tones are more likely to develop PIH and melasma, and their marks often last longer. That's why gentle care and sun protection matter so much in Indian skin.
How dermatologists treat pigmentation
There's no single treatment that suits everyone. A dermatologist will first work out which type of pigmentation you have, because melasma, PIH and sun spots respond differently. A treatment plan may include:
- Topical treatments: prescription or professional creams with brightening and pigment-regulating ingredients.
- In-clinic procedures: chemical peels, lasers or other procedures for stubborn or deeper pigmentation, chosen carefully to avoid irritating the skin.
- Oral treatments: in some cases of melasma, your dermatologist may suggest medicine taken by mouth.
- Maintenance: ongoing home care to keep results from fading, since melasma in particular can return.
Pigmentation fades slowly. Most treatments take weeks to months to show a clear difference, so patience and consistency are part of the plan.
Daily care that helps
What you do every day matters as much as any treatment:
Wear sunscreen every morning
Use a broad-spectrum sunscreen with SPF 30 or higher, even indoors near windows and on cloudy days. A tinted sunscreen also helps protect against visible light.
Reapply when you're outdoors
Reapply about every two hours, and after sweating.
Add physical protection
A wide-brimmed hat, sunglasses and shade all help.
Be gentle with your skin
Avoid scrubbing, picking and harsh products that cause irritation.
Stick with your routine
Changing products too often can irritate skin. Give each routine time to work.
Treat the cause
If acne or another skin condition is leaving marks, treating it early helps prevent new pigmentation.
