Cucurbitacins

These cooling, subtly bitter compounds found in cucumbers and other gourds help give skin that instantly refreshed, just-toned feel by delivering gentle astringency that temporarily tightens the look of pores. They reduce excess sebum, and support a clearer matte finish, while their soothing anti-inflammatory action helps calm redness, puffiness, and irritation for skin that feels fresher, more balanced, and visibly less stressed.
