Pigmentation and melasma on Indian skin: causes and what actually helps

"Pigmentation" is one of the most common reasons people in India visit a skin clinic. But the word covers several different problems, and the right treatment depends on which one you have. A cream that clears a tan can do nothing for melasma, and an aggressive laser that removes a sun spot can make melasma darker.

This guide explains the main types of pigmentation on Indian skin, why they happen, and what actually helps.

Why Indian skin pigments easily

Skin colour comes from melanin, made by cells called melanocytes. Brown skin has active melanocytes that respond quickly to any trigger: sun, heat, hormones, friction or inflammation. That is good protection against sunburn, but it also means that a pimple, a scratch or a harsh product can leave a dark mark behind.

The main triggers are:

• Sun and visible light, the biggest factor by far
• Heat, from cooking, travel or a hot climate such as Surat’s
• Hormones: pregnancy, contraceptive pills, thyroid changes
• Inflammation: acne, eczema, insect bites, waxing burns
• Friction: tight clothes, scrubbing, rubbing with towels
• Some medicines and products, including steroid creams used on the face

The main types of pigmentation

1. Tan

An even darkening of sun-exposed areas: face, neck, arms and feet, often with a visible line where clothing ends. Tan fades on its own over weeks once sun exposure is reduced, and fades faster with gentle exfoliation and daily sunscreen.

2. Marks after pimples (post-inflammatory hyperpigmentation)

Flat brown or dark spots where pimples used to be. These are not scars; the skin is smooth. They fade slowly over months, faster with treatment. The most important step is to stop new pimples, and to stop squeezing them.

3. Sun spots and freckles

Small, well-defined brown spots on the cheeks, nose and hands, increasing with age and sun exposure. These often respond very well to laser.

4. Melasma

Patchy, symmetrical brown or grey-brown areas, typically on the cheeks, forehead, upper lip and nose. Melasma is especially common in women between 25 and 50, and often starts or worsens with pregnancy, hormonal pills or long hours in the sun and heat. It is the most stubborn type, because the pigment-making cells in that area stay "switched on".

5. Dark neck, underarms and skin folds

Velvety dark skin on the neck, underarms or groin can be acanthosis nigricans, which is often linked to insulin resistance, weight gain or PCOS. It is worth a check-up, because treating the underlying cause helps the skin too.

What actually helps

Daily sunscreen is not optional

Every type of pigmentation is made worse by sun and visible light. Without sunscreen, every treatment is working against a daily top-up of new pigment. Use a broad-spectrum sunscreen of SPF 30 or more every morning, including indoors near windows, and reapply if you are outside. Tinted sunscreens with iron oxides also block visible light, which matters for melasma.

Gentle home care

Creams with ingredients such as niacinamide, azelaic acid, vitamin C, kojic acid, tranexamic acid or retinoids can lighten pigment gradually. Which one, and how strong, depends on your skin, so it is best chosen with advice. Avoid lemon juice, baking soda, toothpaste and harsh scrubs: they irritate the skin and can cause more pigmentation.

Chemical peels

Mild peels, such as glycolic, lactic, mandelic or combination peels, speed up the shedding of pigmented skin. A course of 4 to 6 peels a few weeks apart works well for tan and marks, and can help melasma when kept gentle.

Laser toning

A Q-switched laser in a low-energy "toning" mode breaks pigment into tiny particles that the body clears away. It suits sun spots, freckles and stubborn marks, and is used carefully for melasma in a course of sessions.

Treating the trigger

Controlling acne, avoiding friction, reviewing hormonal pills with your doctor and treating insulin resistance all reduce the source of new pigment.

A warning about "fairness" and steroid creams

Some creams sold as fairness or pigmentation creams contain potent steroids, sometimes mixed with hydroquinone and tretinoin. They lighten the skin quickly at first, which feels like success. With continued use they thin the skin, cause redness, visible veins, acne and, when stopped, rebound darkening that is worse than before. If you have been using such a cream, do not keep using it, and show it to a doctor so you can stop it safely.

How long does treatment take?

• Tan: a few weeks
• Marks after pimples: two to four months
• Sun spots: often a few laser sessions
• Melasma: months of treatment, then ongoing maintenance

Melasma can be lightened a great deal and kept under control, but it tends to return with sun, heat and hormonal changes. Thinking of it as a condition to manage, rather than a spot to remove once, makes the results last.

When to see a doctor

• A dark spot that is new, growing, irregular in shape or colour, or bleeding
• Pigmentation that appeared after starting a medicine
• Darkening of the neck or underarms with weight gain, irregular periods or tiredness
• Pigmentation that has not improved after three months of careful home care

The bottom line

Identify the type first, protect your skin every single day, be gentle, and be patient. Most pigmentation improves a lot with the right plan; melasma needs the most care and the most consistency.
