The extract of cucumber is a plant-based ingredient that is widely known for its soothing and emollient qualities. It has been used for ages, even by Cleopatra, to maintain healthy skin. Although it is commonly believed to help reduce puffiness around the eyes, there is no scientific evidence to support this claim. However, studies have shown that cucumber contains amino acids and organic acids that are beneficial for the skin’s acid mantle. Additionally, the pulp of cucumber contains an enzyme known as shikimate dehydrigenase which has anti-inflammatory properties.
