1 : any of various composite plants (genus Chrysanthemum) including weeds, ornamentals grown for their brightly colored often double flower heads, and others important as sources of medicinals and insecticides. 2 : a flower head of an ornamental chrysanthemum.
Elastin is a highly elastic protein in connective tissue and allows many tissues in the body to resume their shape after stretching or contracting. Elastin helps skin to return to its original position when it is poked or pinched.
Specifically, vitamin C has been shown to stabilize collagen mRNA, thus increasing collagen protein synthesis for repair of the damaged skin (47) . This occurs concurrently with a decrease in elastin production; the elastin protein is often overproduced in response to photodamage (48) .n addition to its antioxidant functions, vitamin C regulates the synthesis of the structural protein collagen. The role of vitamin C in the hydroxylation of collagen molecules is well characterized (46) . Hydroxylation of collagen is necessary for its extracellular stability and support of the epidermis.
