Science
Mechanism of Action
This ingredient operates by stimulating the intrinsic synthesis of vital skin proteins, specifically collagen and fibrillin, which are crucial for maintaining skin's youthful structure and elasticity. Concurrently, it inhibits the enzymatic activity responsible for degrading these supportive proteins, thereby preserving skin integrity. Beyond its structural benefits, Hydrolyzed Pumpkin Seedcake acts as an effective skin conditioning agent, improving softness and smoothness. It further protects the skin from transepidermal moisture loss, provides fatty acids for replenishment, and delivers antioxidant compounds like Vitamin E to mitigate environmental damage. The hydrolysis process breaks down proteins into smaller, more absorbable peptides and amino acids, optimizing its dermal utilization.
