Anti-wrinkle creams that really work... 1  A chemical called Matrixyl used in some anti-wrinkle creams may double the amount of collagen in skin. 2  Collagen is needed to keep skin elastic and give it a plump, youthful feel-but production declines with age. 3  Scientists say Matrixyl can help the skin produce more.
Bromelain is an enzyme found in pineapple juice and in the pineapple stem. People use it for medicine. Bromelain is used for reducing swelling (inflammation), especially of the nose and sinuses, after surgery or injury.
Bromelain extract is a mixture of protein-digesting enzymes called proteolytic enzymes or proteases and other substances, extracted from the Bromeliaceae plant family. Pineapples belong to the Bromeliaceae family, and contain two main protein-digesting enzymes: stem bromelain found in the stem, and fruit bromelain found in the fruit. Stem bromelain is the more common source of bromelain used commercially. Bromelain was first isolated by the Venezuelan chemist, Vicente Marcano. Traditonally bromelain has been used as a meat tenderizer because of its ability to digest proteins, but if left on meat for too long, it will turn it to mush.
