Science
Mechanism of Action
This synergistic complex of growth factors actively promotes various cellular processes essential for skin health. sh-Oligopeptide-1, or Epidermal Growth Factor (EGF), enhances skin repair, stimulates self-regeneration, and supports new blood vessel formation, which is crucial for healing without scarring. It also fosters the proliferation of keratinocytes, endothelial cells, and fibroblasts, contributing to improved skin barrier function and long-term moisturization while reducing inflammation and scars. EGF is pivotal in boosting collagen, elastin, and hyaluronic acid synthesis, which are key for a youthful appearance. sh-Oligopeptide-2, or Insulin-like Growth Factor 1 (IGF-1), works cooperatively with EGF to accelerate cell regeneration and wound healing. Additionally, sh-Polypeptide-1 (Basic Fibroblast Growth Factor) is a cell signaling protein that specifically promotes the growth and proliferation of fibroblasts, further supporting skin structure and vitality.

Key findings
- 01 Studies on sh-Oligopeptide-1 (EGF) have shown effectiveness in promoting wound healing in diabetic patients post-laser treatment and in managing Senile purpura.
- 02 A 2012 study involving a serum with barley bioengineered sh-Oligopeptide-1 demonstrated statistically significant improvements in the appearance of fine lines, rhytids, skin texture, pore size, and various dyschromatic conditions within one month, with benefits continuing over a 3-month period.
- 03 Clinical assessments indicate that Oligopeptide-1 can significantly improve fine lines, skin texture, pore size, and dyschromatic conditions within the first month of application.

Dusting Analysis
While some clinical studies report observed improvements with sh-Oligopeptide-1, a critical review article suggests that the scientific basis for its cosmetic efficacy, particularly regarding preclinical bioactivity, has not been conclusively proven. This raises concerns that the ingredient, or its primary active component, may be included in cosmetic formulations without robust fundamental scientific validation for its claims.
The Formula
Formulation
Stability
This peptide complex is sensitive to pH variations; formulations should be adjusted to a pH range of 5.0-8.0 before its incorporation. It is also susceptible to enzymatic degradation by microorganisms, necessitating stringent contamination control during manufacturing. For optimal stability, it should be added in the final formulation step at temperatures below 45℃.
Synergies
- sh-Oligopeptide-2 (IGF-1) works synergistically with sh-Oligopeptide-1 (EGF) to promote enhanced skin cell proliferation.
Safety
Safety Profile
The comprehensive R-peptide complex has not undergone direct safety review by regulatory bodies such as CIR, SCCS, or FDA. However, individual components, such as sh-Oligopeptide-1 (EGF), are generally regarded as safe and biodegradable for cosmetic use. Concerns have been raised regarding the potential for tumorigenesis with cellular overexpression or dysregulation, as EGF signaling is implicated in various tumor cells. Despite this, sh-Oligopeptide-1 is authorized for general cosmetic use across various concentrations, though its long-term risks remain undefined. The CIR has broadly deemed 'Tissue-Derived Proteins and Peptides' and 'Ectodermal-Derived Proteins and Peptides' as safe under current practices. SkinSAFE further classifies sh-Oligopeptide-1 as 'Teen SAFE', 'Baby SAFE', 'Eyelid SAFE', and 'Irritant Free'.

Verdict
While this complex of growth factors presents a plausible mechanism for skin regeneration and some clinical observations suggest anti-aging and wound healing benefits, the overall complex lacks direct regulatory safety review, and a significant debate exists regarding the foundational scientific basis for the cosmetic efficacy and long-term safety of its key components.
