Elastases are enzymes released from neutrophils and dermal fibroblasts , and are thought to be produced through a signal cascade that is induced by skin inflammation resulting from UV damage. Neutrophils are typical inflammatory cells that secrete neutrophil elastase (NE) in the acute inflammation phase. NE is a well-studied elastase that cleaves a variety of proteins. A relationship between UV exposure and neutrophil infiltration in skin has been suggested, and it has been reported that neutrophil infiltration inhumanskinisobservedafter a single erythemaldose of irradiation by solar simulated radiation UV. It is known that interstitial collagenases MMP-1 mainly act as damage factors to type I collagen in the dermis, and their activity is elevated following UV irradiation NE indirectly plays a role in skin photoaging through MMP activation (1). Natural compounds are a potential source of HNE inhibitors (2).
· Inhibits the production of MMP-which is a major protein involved in collagen breakdown
· Increases skin density (as a result of increased collagen synthesis) · Protects cells against the effects of UV radiation exposure
· Inhibiiıon of Neutrophil Elastase
