About 1,2,4-TRIHYDROXYBENZENE
A synthetic dye or pigment used to add color rather than improve skin health.
Detailed Analysis
1,2,4-TRIHYDROXYBENZENE is a synthetic color additive or hair-dye ingredient used to deposit color rather than improve barrier function or hydration. Colorants and dye intermediates sit in a higher-scrutiny part of cosmetics safety because irritation and sensitization matter more here than with bland emollients. In finished cosmetics, risk is usually driven more by concentration and formulation context than by the ingredient name alone.
