Elastase Inhibition & Skin Elasticity Support
In Simple Terms:
Red maple leaf extract has demonstrated strong inhibitory effects on elastase — the enzyme responsible for breaking down elastin, a key protein that maintains skin elasticity and flexibility.
Key Findings:
Significant elastase inhibition observed in controlled laboratory studies
Activity comparable to known antioxidant compounds
Supports preservation of skin elasticity over time
Study Breakdown:
Elastase is an enzyme that degrades elastin, a structural protein responsible for maintaining the skin’s elasticity and resilience.
In controlled laboratory conditions, red maple leaf extract showed strong inhibitory activity against elastase, suggesting its ability to help reduce the breakdown of elastin fibers.
The extract contains galloylated catechins — a class of bioactive compounds known for their antioxidant and enzyme-inhibiting properties. These compounds are believed to play a key role in slowing enzymatic degradation of structural proteins.
Why It Matters for Your Skin:
As elastin breaks down, skin gradually loses its ability to maintain firmness and bounce.
By helping inhibit elastase activity, red maple leaf extract supports the preservation of skin elasticity — contributing to smoother, more resilient-looking skin over time.
