Science
Mechanism of Action
This synthetic peptide acts by mimicking Royalactin, engaging with human growth factor receptors such as EGF and TGF-α. This interaction stimulates the synthesis of extracellular matrix (ECM) components and boosts dermal cell proliferation, accelerating tissue regeneration. Furthermore, Pentapeptide-48 activates proteasomes, crucial for eliminating old or damaged proteins, thereby facilitating cellular waste removal and promoting a clear, radiant appearance.

Formulation
Stability
For enhanced stability and efficacy, Pentapeptide-48 is frequently incorporated into formulations within an encapsulated delivery system, such as soft spherical carriers often using shea butter. This encapsulation protects the peptide from degradation, improves skin penetration, optimizes uptake by keratinocytes, and allows for controlled release.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) has not conducted a specific safety assessment for Pentapeptide-48, although other pentapeptides have been reviewed. Data availability for Pentapeptide-48 on platforms like EWG is noted as 'LIMITED-FAIR', indicating a need for more comprehensive independent safety evaluations specific to this ingredient.
