Babor's clarifying Exfoliating Toner, the successor to the Aha Bha Toner, supports skin renewal and refines the skin's texture with an effective acid combination of 9% Aha (mandelic acid), Bha (salicylic acid) and Pad (azelaic acid derivative). In addition, nourishing panthenol moisturizes the skin and strengthens the skin's protective barrier.
