Medicube Zero Pore Blackhead Mud Mask – clarifying clay mask with AHA, BHA & PHA The Medicube Zero Pore Blackhead Mud Mask deeply cleanses pores with a unique combination of clays (kaolin, bentonite, montmorillonite) and chemical exfoliating acids. AHA (glycolic acid), BHA (salicylic acid), and PHA (gluconolactone) help remove dead skin cells, unclog pores, and regulate excess sebum. At the same time, soothing ingredients such as allantoin, green tea extract, and guaiazulene have a calming and regenerative effect. The blue mask, with its creamy consistency, gives a mattified, refined complexion – without any feeling of tightness.
