We love Neostrata for its pioneering approach to skin surface renewal, and the benefits of exfoliating acids. Neostrata was one of the first cosmeceutical brands to launch, back in 1974. They were the first to discover the effects of Alpha hydroxy acids (AHAs) in skincare, and their whole brand ethos focuses on skin renewal, and the benefits of resurfacing ingredients to support our skins natural renewal process. All formulas are pH adjusted for best absorption into the skin.
