Soin visage jour et nuit

Why it's rated this way

2 ingredients on this label are flagged. A cosmetic's rating is set by its most serious finding — here, Sodium Hydroxide.

1. Sodium HydroxideMinor concernAlkali (lye). It is used up in the product: as a pH adjuster it neutralises an acid in the formula, and in soap it turns the oils into soap. The EU caps the alkalinity it may leave (pH 11 for pH-adjuster use); the higher limits, with warnings, are only for hair straighteners, cuticle removers and depilatories.

   What it is
