Resorcinol

Explained

Resorcinol, or 1,3-benzenediol, is a small phenolic compound with antioxidant, denaturant, hair dyeing, and perfuming properties.

In cosmetics, rescorcinol is mostly found in hair dyes rather than leave-on-face products. Related "resorcinol-type" ingredients can act keratolytic (loosen dead skin cells) but plain resorcinol is not usually found in face products.

In haircare, it is used to create a long-lasting color by participating in dye-forming reactions.

The main downside of this ingredient is allergy risk; it is considered a moderate skin sensitizer in animal data. Human sensitization rates are generally low in broader clinical data.

In the EU, resorcinol is restricted and only allowed under specific conditions for hair products (up to 1.25% hair dye after mixing and up to 0.5% in certain hair lotions/shampoos.
