Science
Mechanism of Action
Functioning as an Epidermal Growth Factor (EGF) mimic, rh-Oligopeptide-1 stimulates crucial cellular processes for optimal skin health. It drives the proliferation and differentiation of epidermal cells, accelerating cell growth and promoting wound healing, thereby enhancing the skin's structural integrity. This ingredient significantly boosts the production of vital extracellular matrix components such as collagen, elastin, and hyaluronic acid, leading to increased skin elasticity, a reduction in the appearance of fine lines and wrinkles, and improved barrier function. Additionally, it contributes to sustained moisturization and helps to reduce inflammatory responses within the skin.

Key findings
- 01 Clinical evaluations of a serum containing barley bioengineered epidermal growth factor demonstrated statistically significant improvements in fine lines, rhytids, skin texture, pore size, and various dyschromatic conditions within one month, with continued enhancement observed over three months.

Dusting Analysis
Specific effective concentrations for TRANSGENIC TOBACCO RH-OLIGOPEPTIDE-1 in cosmetic formulations are not explicitly detailed in available research, making it difficult to establish dusting thresholds. Given its nature as a potent growth factor, it is likely used in precise, low concentrations rather than as a 'dusted' ingredient.
The Formula
Formulation
Stability
rh-Oligopeptide-1 (EGF) is sensitive to pH; formulations should be adjusted to a pH between 5.0 and 8.0 before incorporating the diluted EGF solution. Maintaining the activity of growth factors like EGF is challenging, often requiring storage at extremely cold temperatures (-20°C) in laboratory settings for stability. It is susceptible to decomposition by microbial enzymes, necessitating rigorous control of microbial contamination during processing. Due to its medium size and polar nature, a specialized delivery system may be required for effective skin penetration.
Conflicts
- Microbial contamination (leads to decomposition by enzymes and loss of activity)
- Extreme pH values outside the 5.0-8.0 range
Safety
Safety Profile
Nicotiana Benthamiana rh-Oligopeptide-1 is listed in the EU CosIng database under Cosmetics Regulation provisions II/416 with a 'SKIN PROTECTING' function, indicating its allowance in cosmetics with certain restrictions. While active EGF is considered a potent unauthorized drug in some contexts, sh-oligopeptide-1 (often used interchangeably with rh-Oligopeptide-1) is permitted as a cosmetic ingredient in various concentrations, though its long-term risks remain unknown. Experts agree that EGF is mitogenic (stimulates cell proliferation) but not mutagenic (does not alter cells to become cancerous). However, a significant concern is that if pre-existing cancerous cells are present, EGF can promote their spread. Given that EGF signaling is often observed in tumor cells, a theoretical potential for tumorigenesis exists with any overexpression or dysregulation in personal care applications. It is advised to avoid using growth factors if you have psoriasis or are at risk of skin cancer.

Verdict
While TRANSGENIC TOBACCO RH-OLIGOPEPTIDE-1 offers potent regenerative and anti-aging benefits as an EGF mimic, its lack of specific concentration data, 'not reviewed' safety status by CIR, and potential to promote existing cancerous cell growth necessitate significant caution in formulation and use.
