Glycerin soap, with an acidic pH (more similar to our skin) with ingredients that have a depigmenting effect on spots, melasma, and lentigo, made from Organic Turmeric from our garden and Flaxseed, organic virgin Coconut oil, and lactic acid which gently exfoliates and helps reduce melanin production and interferes with tyrosin synthesis. *Theoretically, human test results are still pending* Thank you
