The present invention relates to a collagenase inhibitor containing a poly-gamma-glutamic acid-vitamin C complex (PGA- VitC conjugate), and a composition for preventing skin wrinkles, which contains the PGA- VitC conjugate and can be used in drugs, cosmetics and foods. The PGA- VitC conjugate has not only the effect of inhibiting collagenase activity, but also antiaging effects, such as an antioxidant effect and a skin wrinkle-improving effect. Also, the collagenase inhibitor maintains the elasticity of the skin by keeping skin connective tissue taut and has high skin compatibility, excellent moisturization effect, moisture-absorbing effect and sustained-release effect. Thus, it is useful to provide cosmetic, pharmaceutical and food compositions for improving skin elasticity and reducing wrinkles. |
