Science
Mechanism of Action
This ingredient functions by binding to specific epidermal growth factor receptors (EGFRs) on keratinocytes, initiating intracellular signaling cascades. This precisely orchestrated action stimulates epidermal cell proliferation and differentiation, leading to accelerated skin renewal and tissue repair. Furthermore, it enhances fibroblast vitality, promoting the endogenous synthesis of critical structural proteins like collagen and elastin, thereby improving skin firmness and elasticity. It also aids in microcirculation, modulates inflammatory responses, minimizes scarring, and contributes to sustained hydration through increased extracellular matrix components such as hyaluronic acid.

Key findings
- 01 A 2012 study demonstrated significant improvements in the appearance of fine lines, wrinkles, skin texture, pore size, and various pigment abnormalities within the first month of use, with benefits sustained over 3 months, when a serum containing bioengineered EGF was applied.
- 02 An EGF-containing cream reduced inflammatory acne lesions by 33.5% over six weeks in a study involving 20 subjects.
- 03 Clinical investigations have shown efficacy in accelerating wound healing for diabetic patients post-laser treatment and in managing Senile purpura.
- 04 In one study, 73% of participants experienced a decrease in melasma without reported side effects after applying a topical EGF serum twice daily for 8 weeks.

Stability
Maintaining the biological activity of SH-Oligopeptide-88 in finished products is challenging; typically, only 5-10% of active growth factors may remain stable at room temperature. Laboratory storage often requires very cold temperatures (-20°C). However, advanced forms exist that claim enhanced room-temperature stability. It should be incorporated at the final formulation step, ensuring temperatures remain below 45°C. Due to its large molecular weight, specialized delivery systems may be essential for optimal skin penetration.
Safety
Safety Profile
SH-Oligopeptide-88 is generally recognized as safe for cosmetic use by regulatory bodies like the European Cosmetics Regulation, though sensitivity patch tests are advised for susceptible individuals. Concerns stem from its mitogenic (cell proliferation stimulating) activity, theoretically raising questions about tumorigenesis if cancerous cells are present or growth factor regulation is impaired; however, experts confirm it is mitogenic but not mutagenic (non-carcinogenic). The China National Drug Administration advises against its use as a cosmetic raw material due to large molecular weight hindering absorption and potential safety implications if the skin barrier is compromised. It is recommended to avoid EGF products if you have psoriasis or are at an elevated risk of skin cancer.
