What each input rests on

The three ratings behind the score, and the studies each rests on
Input	Rating	Evidence
Chemical hazard	9/10	A review of 31 reports found inorganic mercury from skin-lightening creams absorbed through the skin, with a half-life of about 1-2 months; it deposits in the kidneys (proteinuria, nephrotic syndrome) and prolonged use can cause neurotoxicity. Poisonings were reported on five continents.

What this means for you

The chemical-hazard rating is what drives the score down. The FDA and EPA warn that some imported skin-lightening creams contain mercury at dangerous levels, which absorbs through skin and accumulates in the body and nervous system. There is no safe use — check labels for 'mercurous chloride', 'calomel' or 'mercurio' and discard them.
