Abstract
The present invention relates to a hyaluronidase inhibitor containing poly-gamma-glutamic acid (PGA) as an active ingredient, a composition for maintaining skin elasticity and a composition for improving allergy, wherein each of the compositions contains PGA as an active ingredient. The inventive compositions containing PGA are effective in maintaining skin moisturization and skin elasticity by effectively inhibiting the activity of hyaluronidase which is an enzyme that degrades hyaluronic acid present in the skin dermis. Also, the compositions can relieve allergic symptoms by inhibiting the permeability of inflammatory cells.
