Melasma (Jhaiyan) in South Asian Skin: Sunscreen Is the Whole Game

The tube said “fairness” and cost less than a plate of chaat. Eight weeks later the brown patches on her cheeks were darker, the skin between them was thin and shiny, and fine veins had appeared where there were none. That is the usual story behind melasma (jhaiyan or chhaiyan) in a South Asian face, and this Desi Remedies guide is the honest version: what melasma is, why it loves our skin, why sunscreen is the whole game, what creams can and cannot do, and why the steroid and mercury “fairness” creams sold at every counter are the fastest way to make it permanent.

What jhaiyan actually is

Melasma is a pattern of symmetrical brown or grey-brown patches, most often across the cheekbones, the forehead, the bridge of the nose, the upper lip and the chin. It isn’t a tan, though sun drives it. It isn’t dirt, though a hundred ubtans will be tried on it. It’s pigment cells that have become over-active in specific patches of skin and now respond to every trigger, light, heat, hormones, friction, by producing more pigment than the skin around them.

South Asian skin, broadly types IV and V on the dermatologist’s scale, has more active melanocytes to begin with, which is the same reason we tan rather than burn and the same reason a pimple leaves a brown mark for months. Melasma sits in that biology. It’s very common in women between 20 and 50, especially after pregnancy or on the pill, and it happens in men too, particularly outdoor workers and drivers, who get it on the side the window is on.

Why sunscreen is the whole game

Every cream, peel and laser for melasma fails without sunscreen, and most people who “tried everything” never got this step right. Melasma pigment cells are triggered not just by UVB (the burning rays) and UVA (the ageing rays, which pass through glass and cloud), but by ordinary visible light and by heat. That means a car window, a sunny room, a kitchen stove at iftar time and the glow of a June afternoon all keep the patches active even if you never stand in direct sun.

1. Choose a broad-spectrum sunscreen of SPF 50 (SPF 30 minimum) that says UVA protection on the label. For melasma, a tinted one containing iron oxide is worth seeking out, because the tint is what blocks visible light; a plain white sunscreen doesn’t.
2. Measure it. Two full finger-lengths (index and middle finger, base to tip) for the face alone, and another finger-length or so for the neck. Most people use a third of that and get a third of the protection. The two-finger rule shows the method.
3. Apply it every morning, 15 minutes before going out, over moisturiser and under any makeup. Indoors near windows counts. Cloudy days count. Winter counts.
4. Reapply every 2 to 3 hours while outdoors, and after sweating or wiping the face. A powder or stick sunscreen over makeup makes the midday top-up practical.
5. Add physical shade: a wide dupatta or hat, sunglasses, the shady side of the road between 10am and 4pm, and a sun visor in the car on your window side.
6. Give it 12 weeks before you judge anything else. Sunscreen alone, done properly, visibly lightens melasma for many people in one season, simply by stopping the daily re-darkening.

What the creams can and cannot do

Melasma creams work by slowing pigment production and speeding up the turnover of pigmented skin. They lighten patches; they don’t remove the over-active cells, which is why melasma comes back when protection lapses and why “cure” is the wrong word for any of them.

From a pharmacy, without a prescription

Azelaic acid (10 to 20%), niacinamide (4 to 5%), vitamin C serums, kojic acid, arbutin, and topical tranexamic acid are all reasonable, gentle, and safe for long use, including, for azelaic acid and niacinamide, in pregnancy after checking with your doctor. Expect modest fading over 3 to 6 months of nightly use, always with daytime sunscreen. Start one at a time. If a product stings for more than a minute or leaves the skin red, stop; irritation triggers pigment in brown skin and undoes the work.

From a dermatologist

Hydroquinone at 2 to 4% is the strongest proven lightener and it’s prescription-strength for good reason: it’s used in short courses of 8 to 12 weeks, then rested, because long, unsupervised use in dark skin causes ochronosis, a permanent blue-black staining that is far worse than the melasma. The “triple combination” cream (a low-dose steroid, hydroquinone and tretinoin together) is a dermatologist’s tool for a limited number of weeks with follow-up; it is not a cream to keep buying. Oral tranexamic acid, chemical peels and certain lasers are options a dermatologist may choose for stubborn cases, and in type IV and V skin each of those can make melasma worse if done aggressively or by an untrained hand, which is the honest reason to be wary of salon “pigmentation packages”.

Why steroid and mercury “fairness” creams make it worse

The creams that darken melasma are the ones sold to remove it. Walk into any pharmacy or beauty shop and ask for “jhaiyan ki cream” and one of three things is handed over.

A steroid cream, often betamethasone or clobetasol, sometimes disguised inside a “fairness” or “night cream” with a herbal name. It lightens for a few weeks by suppressing inflammation and thinning the skin, and then the bill arrives: thin, shiny, fragile skin, visible veins, acne, fine hair, and rebound darkening worse than the original patch every time you stop. The steroid-dependent face is now its own diagnosis in South Asian dermatology clinics, and it is far harder to treat than melasma was.

A mercury cream, banned in most of the world and still turning up in imported and unlabelled “whitening” jars. Mercury blocks pigment production, and it also passes through the skin into the blood, where it damages the kidneys and the nervous system over months, and it contaminates the people you live with through towels and touch. Any product with no ingredient list, an unreadable label, or a suspiciously fast result belongs in the bin.

Unregulated hydroquinone at high strength, sometimes 6 to 8%, sold loose or in “combination” tubes with the steroid and tretinoin, used month after month because it “works”. That’s the route to ochronosis. The same logic applies to the drips and pills sold for whitening; our explainer on glutathione drips covers that industry.

Myth: lemon, haldi and a good scrub will fade jhaiyan

Lemon juice on the face is acid on skin that then goes into the sun; it causes burns and dark marks (phytophotodermatitis), and it makes melasma darker. Scrubs and rough ubtans create friction and irritation, and in brown skin irritation means pigment. Haldi paste stains, does nothing to melanocytes, and can sensitise the skin. Gentle is the rule: a mild cleanser, a moisturiser, the sunscreen, and a single active at night. Anything that leaves the face pink has just fed the melasma.

Triggers you can actually change

Heat is the one nobody mentions. Standing over a tawa or a deep-fryer for an hour a day keeps the cheeks warm and flushed, and melasma responds to warmth much as it responds to light. Cook with the exhaust fan on, step back between rotis, and splash the face with cool water afterwards. Threading and waxing of the upper lip and brows cause friction and inflammation right where melasma sits; if the upper lip is a patch, consider gentler hair removal or simply leaving it longer between sessions. Fragranced creams and some “herbal” oils cause low-grade irritation on the face and are best left off melasma-prone skin. Hormonal contraception is a known trigger; if melasma began or flared with the pill, that’s worth raising with the doctor who prescribed it, without stopping it on your own. Thyroid disease is linked with melasma and a TSH test is reasonable if there are other symptoms.
