Medik8 Clarifying Foam™ Oil-Free AHA/BHA Blemish Cleanser is crafted with potent blemish-banishing actives: salicylic acid, mandelic acid, natural tea tree oil and niacinamide. Leaders in synergistic exfoliation, these AHAs (alpha hydroxy acids) and BHAs (beta hydroxy acids) work in harmony to unveil a clear, blemish-free complexion. Comfort is provided by niacinamide while tea tree oil detoxifies. The pH-balanced formula ensures skin is not left dry or tight. This foaming cleanser couples perfectly with Lipid Balance Cleansing Oil for maximal makeup removal power. Blemish Busting Clarifying Foam penetrates deep with salicylic acid to break apart congested pores which often result in blemishes. L-mandelic acid, with dual AHA and BHA properties, exfoliates dead skin cells.
