|May 28, 2009
Summary
Non-denatured soybean extracts boost elastin production and protect skin fibers from degradation. This suggests soy may be a beneficial ingredient for anti-aging skincare products.
Area of Science:
- Dermatology and Cosmetology
- Biochemistry of Extracellular Matrix
Background:
- Elastic fibers are crucial for skin elasticity and resilience.
- Skin aging is characterized by decreased elastin synthesis and increased elastase activity, leading to sagging.
- Current anti-aging strategies often focus on mitigating these molecular changes.
Discussion:
- Non-denatured Glycine max (soybean) extracts were investigated for their effects on elastic fibers.
- In vitro studies demonstrated that soy extracts stimulate elastin promoter activity and inhibit elastase.
- Soy extracts protected elastic fibers from degradation by exogenous elastases.
Key Insights:
- Topical application of soybean extracts on mouse and swine skin enhanced the elastic fiber network.
- Desmosine content, a marker of mature elastin, was significantly increased post-treatment.
- Soy treatment augmented elastin expression in human skin grafts on SCID mice.
Outlook:
- Non-denatured soybean extracts show potential as effective skincare agents.
- Further research could explore optimal formulations and long-term efficacy for anti-aging benefits.
- Soybean-derived compounds may offer a natural approach to combatting skin aging signs.

01:12Elastin is Responsible for Tissue Elasticity
Elastic fiber contains the protein elastin along with lesser amounts of other proteins and glycoproteins. The main property of elastin is that it will return to its original shape after being stretched or compressed. Elastic fibers are prominent in elastic tissues found in skin and the elastic ligaments of the vertebral column.
Ligaments and tendons are made of dense regular connective tissue, but in ligaments not all fibers are parallel. Dense regular elastic tissue contains elastin fibers and...

01:23Role of Matrix Metalloproteases in Degradation of ECM
Matrix metalloproteases (MMPs) are enzymes involved in the hydrolysis of proteins and glycoproteins of the extracellular matrix. MMPs are essential for the migration and proliferation of cells through the dense matrix network, throughout embryonic development, and throughout morphogenesis. The first MMP activity discovered was a collagenase in a tadpole's tail undergoing metamorphosis. The active collagen deposition and modifications lead to the morphogenesis of tadpoles into the adult body.
