Fairness creams, mercury and steroid misuse: the part of the beauty aisle that is a health story

Most of this blog is about choosing between reasonable products. This post is about a corner of the market where the question is not which one is better but whether the thing in your hand should legally exist.

Mercury: banned, and still found

Mercury compounds inhibit the enzyme that produces melanin, which makes skin visibly lighter within a couple of weeks. That speed is exactly why they are added illegally, and it is why an unusually fast result is a warning sign rather than a selling point.

Mercury is not permitted in cosmetics in India under the Drugs and Cosmetics framework. Despite that, testing by the Centre for Science and Environment found mercury in a substantial share of the skin-lightening creams it analysed, several of them far above any permissible trace level. State regulators, including the Maharashtra FDA, have issued public warnings about mercury-laced lightening creams.

The harm is not cosmetic. Repeated application can cause skin discolouration and scarring, and mercury absorbed through skin can damage the kidneys and the nervous system. It is also excreted in breast milk.

Highest-risk purchases: unlabelled or partially labelled creams, imported products with no Indian importer details, anything sold loose or repackaged, and anything promising visible lightening in seven to fifteen days.

Topical steroids: prescription drugs sold like cosmetics

Potent topical corticosteroids - clobetasol, betamethasone, mometasone and their fixed-dose combinations - are prescription (Schedule H) drugs in India. They are genuinely useful medicines for specific conditions, used for defined periods under supervision.

They are also widely sold over the counter as fairness or anti-acne creams, often in combinations with an antifungal and an antibiotic. The Indian Association of Dermatologists, Venereologists and Leprologists has campaigned against this for years, because dermatology clinics see the consequences constantly.

• Skin thinning, visible vessels and stretch marks that do not reverse.
• Steroid-induced rosacea and perioral dermatitis.
• Rebound flares worse than the original problem when the cream is stopped - which is what makes people dependent on it.
• Masked and spreading fungal infections, a major driver of hard-to-treat tinea in India.
• Acneiform eruptions and increased facial hair.

The practical rule for a shopper: if a cream requires you to keep using it to hold a result, and stopping makes your skin worse than before, stop buying it and see a dermatologist about how to come off it safely. Abrupt withdrawal from a potent steroid needs guidance.

What the advertising law says

Advertising in this space is regulated by the Drugs and Magic Remedies (Objectionable Advertisements) Act, 1954, and a 2020 draft amendment proposed sharply higher penalties - including fines up to Rs 50 lakh and imprisonment - for advertisements making fairness and similar claims. Cosmetic claims themselves fall under the Cosmetics Rules, 2020, under which label claims cannot go beyond what is permitted without approval.

Industry practice has shifted in response: fairness has largely been rebranded as glow, radiance and tone. The rebrand does not change what is in the tube, which is why the ingredients list still deserves your attention.

What actually works for pigmentation

There are effective, legal, well-studied options for uneven tone and dark patches. None of them change your baseline skin colour, and all of them are slow.

• Daily broad-spectrum sunscreen, applied properly. Nothing else in this list works without it.
• Niacinamide, azelaic acid, vitamin C, alpha arbutin, kojic acid and tranexamic acid in cosmetic formulations.
• Retinoids, which improve turnover and help fade marks over months.
• Prescription options, including hydroquinone-containing regimens, which in India should be used under a dermatologist because of side effects with long unsupervised use.
• Procedures - peels, lasers - which for Indian skin types need a practitioner experienced in treating them, because the wrong setting causes exactly the pigmentation it is meant to treat.

A six-point safety check

• Full ingredients list present and legible.
• Manufacturer and, for imports, importer details, as the Cosmetics Rules require.
• Manufacturing date, batch number and expiry or period-after-opening symbol.
• No promise of dramatic lightening in days.
• No prescription drug names in the ingredients - if you see a steroid, an antifungal or an antibiotic, you are holding a medicine, not a cosmetic.
• Bought from a seller you can go back to if something goes wrong.

If a product you used has caused a reaction, keep the tube and the batch number and take both to a doctor. That pack is also what a complaint to the state drug control authority needs in order to lead anywhere.
