I have a friend who uses it, it's made in South Africa, it lightened her slowly and evenly. But she complained the products are so small. She uses the soap, tiny jar, serum and facial toner.
I think it has unlisted hq though but it shouldn't be more than 1.9% since her lightening was really slow and gracdual. Her skin looks great. But she never really had problem skin to begin with. She's lightened 1.5-2 shades.
