Science
Mechanism of Action
This ingredient functions as a 324-amino acid recombinant human CTGF analog, specifically designed to mimic the Insulin-like Growth Factor (IGF)-binding domain of endogenous CTGF. By precisely regulating gene expression within fibroblasts, it reactivates pathways responsible for collagen synthesis. Given that natural CTGF levels decline with age, topical application of SH-POLYPEPTIDE-93 aims to restore these crucial signaling functions, thereby boosting collagen, enhancing elasticity, and increasing dermal density.

Key findings
- 01 Topical application of sh-Polypeptide-93 has been shown to mimic connective tissue growth factor (CTGF) action, leading to enhanced collagen production, improved skin elasticity, and increased dermal thickness, conferring skin-firming, anti-wrinkle, and wound-healing benefits.

Dusting Analysis
There is no available data to suggest that SH-POLYPEPTIDE-93 is commonly used at sub-efficacious concentrations or primarily for 'dusting' purposes.

Safety Profile
While generally described as safe and effective, the Cosmetic Ingredient Review (CIR) currently reports 'insufficient data' for SH-POLYPEPTIDE-93 specifically, having only reviewed broader categories of proteins and peptides. Paula's Choice also lists it as 'Not rated' with 'No known benefits,' indicating a lack of comprehensive, publicly available research to fully assess its safety or efficacy by their standards.

Verdict
SH-POLYPEPTIDE-93 demonstrates promising mechanistic actions and initial clinical indications for collagen stimulation and anti-aging benefits; however, comprehensive, independent safety and efficacy data remain limited, warranting further research.
