Enzymes are organic substances that sustain life; proteins that act as catalysts, or accelerators, during chemical reactions happening continually throughout the body. Some reactions need to happen quickly, such as the enzymes involved in breaking down big protein or fat molecules into smaller ones during digestion. The enzyme processes working in your skin are not quite as fast as in the gut, but they react at an impressive rate when you realize what their work encompasses. According to the American Academy of Dermatology, you have 19,000,000 skin cells per square inch covering 20 square feet of skin across your body, if you are an average adult. Enzymes from natural sources, such as fruits, working with the enzymes in and on your skin, can come together in a dramatic dance to revitalize your skin and return a youthful glow and feel to your face, neck or anywhere you want to improve texture or appearance.
