Science
Mechanism of Action
This ingredient functions as a synthetic recombinant analog of human Epidermal Growth Factor (EGF). It precisely binds to epidermal growth factor receptors (EGFR) on skin cell surfaces, initiating a complex cascade of cellular events that promote cell survival, differentiation, and proliferation. This process actively stimulates skin repair mechanisms, accelerates cellular self-regeneration, enhances microcirculation, and boosts the localized secretion of rejuvenating growth factors. It specifically encourages the proliferation of keratinocytes in the corneous layer, endothelial cells, and fibroblasts, leading to a fortified skin barrier, modulated inflammatory responses, and diminished appearance of cutaneous scars. Furthermore, it crucially stimulates the production of vital extracellular matrix components like collagen, elastin, and glycosaminoglycans (e.g., hyaluronic acid), which are integral for maintaining skin firmness, elasticity, and prolonged hydration, alongside activating the skin's inherent repair pathways.

Key findings
- 01 Clinical studies consistently show statistically significant improvement in the appearance of fine lines and rhytids, overall skin texture, pore size, and various dyschromatic conditions, with results evident within the first month and continuing to improve over a three-month period.
- 02 An EGF-containing cream demonstrated a significant increase in skin moisture and elasticity, coupled with a notable decrease in transepidermal water loss (TEWL) after one week of application, indicative of an improved skin barrier function.

The Formula
Formulation
Stability
S-MOUSE OLIGOPEPTIDE-1 exhibits significant pH sensitivity, necessitating careful adjustment of the formulation's pH to a range of 5.0 to 8.0 prior to its incorporation for optimal results. Due to its susceptibility to enzymatic degradation by microorganisms, stringent measures to prevent microbial contamination during manufacturing are crucial for maintaining stability and efficacy. As a medium-sized, polar molecule, specialized delivery systems may be beneficial to optimize skin penetration and ensure maximal biological activity.
Safety
Safety Profile
S-MOUSE OLIGOPEPTIDE-1 is generally considered safe for cosmetic application, being both biodegradable and naturally present in the human body. It is not listed on EWG's Restricted or Unacceptable Lists and is deemed unlikely to be carcinogenic in humans. While concerns have been theoretically raised due to EGF being a 'growth factor' and its association with cell signaling in tumor cells, experts largely agree that its topical application is mitogenic (stimulates cell proliferation) but not mutagenic (does not alter cells to make them cancerous). Current research indicates that topically applied recombinant human EGF (rhEGF) remains localized within the epidermis, without penetrating deeply enough to influence systemic cell growth or stimulate cancer cell proliferation. However, as a precautionary measure, individuals with a history of skin cancer, excessive UV exposure, numerous moles, or psoriasis should consult a healthcare professional prior to using products containing EGF.
