This is iS Clinical's hero product, and you'd be hard pushed to find a less than 5* review on it. Its clinically-proven combination of sugar cane extract (8%), bilberry extract (2%), and willow bark extract (2%) provide natural extracts of glycolic, lactic and salicylic acids, which work together to resurface and decongest pores, clearing breakouts and blackheads and refining overall skin texture. Arbutin and mushroom extract work to reduce pigmentation left by acne.
