Is your fairness cream hiding something?

Mercury and strong steroids are often added to “whitening” and “melasma” creams without being written on the label. Check your product’s warning signs and your symptoms in two minutes.

Why the label is not enough

In laboratory tests of whitening creams sold in Islamabad, mercury ranged up to 18,210 parts per million, and only one of fifteen creams was within the FDA limit of 1 ppm.1 A study of creams sold in Faisalabad also found mercury and other heavy metals above WHO limits.2 Products like these rarely list mercury honestly, so how a product is sold and how your skin and body respond matter.

This check can show warning signs, but it cannot prove whether a product contains mercury or steroids; only laboratory testing can. It does not diagnose poisoning or any condition. If you feel very unwell, seek medical care immediately. Beta: under medical review.
