Science
Mechanism of Action
This complex operates by signaling key cellular processes within the skin. Specifically, sh-Oligopeptide-1, identified as Epidermal Growth Factor (EGF), binds to epidermal growth factor receptors (EGFR) on the surface of skin cells. This interaction activates intracellular cascades that drive cellular growth, proliferation, and differentiation, while also facilitating tissue repair. The result is an increased production of new skin cells, enhanced synthesis of vital structural proteins like collagen and elastin, and a boost in hyaluronic acid levels, collectively improving skin barrier function, minimizing fine lines, and contributing to comprehensive skin rejuvenation.

Key findings
- 01 A 2012 study on a serum featuring barley bioengineered sh-Oligopeptide-1 demonstrated statistically significant improvements in fine lines, wrinkles, skin texture, pore visibility, and various discoloration issues within the first month, with positive trends sustained over three months.
- 02 Another clinical trial observed that an EGF-containing cream, which included sh-Oligopeptide-1, enhanced skin moisture and elasticity and reduced transepidermal water loss (TEWL) after just one week, suggesting an improvement in skin barrier function.
- 03 sh-Oligopeptide-1 has also been noted for its efficacy in wound healing for diabetic patients following laser treatment and in addressing Senile purpura across multiple clinical trials.

Stability
While specific stability notes for the full complex are unavailable, components like sh-Oligopeptide-1 are known to maintain good stability at room temperature, precluding the need for low-temperature storage. For optimal integration, it should be added at the final step of formulation, ensuring the temperature remains below 45℃.
Safety
Safety Profile
Specific safety evaluations by regulatory bodies such as CIR, SCCS, or FDA are not available for the complete ingredient complex. For its prominent component, sh-Oligopeptide-1 (EGF), discussions exist regarding its classification as a 'growth factor' and the theoretical potential for tumorigenesis if its signaling pathways are overexpressed or dysregulated, given its presence in numerous tumor cells. However, the prevailing expert view is that EGF is mitogenic, stimulating cell proliferation, but not mutagenic, meaning it does not transform cells into cancerous ones in healthy individuals. While sh-Oligopeptide-1 is permitted for cosmetic use at various concentrations, its long-term safety profile remains undefined. Precaution is advised for individuals with a history or diagnosis of skin cancer. Furthermore, the CIR Panel has previously requested additional data on related oligopeptides, including palmitoyl tripeptide-1 and hexapeptide-12, due to concerns about their capacity to promote angiogenesis and tumor growth.
