Pumpkin Seed Extract is a hydrolyzed protein fraction obtained from the Cucurbita pepo (pumpkin) seedcake. This active ingredient functions by stimulating the synthesis of collagen and fibrillin and by inhibiting the activity of enzymes which contribute to its degradation. Pumpkin Seed Extract is excellent for use in formulations where an increase in smoothness, firmness, elasticity and skin tone is desirable. It is especially recommended for anti-aging formulations.
