Description:

WARNING: This product is for research use only, not for human or veterinary use.

Hydroquinine is an organic compound that is closely related to quinine-derivative drugs and contains anti-malarial and anti-arrhythmia activities. Hydroquinine is used in skin lightening creams and lotions because it is an effective bleaching agent, slowing the production of the tyrosinase enzyme and reducing the amount of melanin formed.
