Science
Mechanism of Action
This ingredient operates at a genetic level by targeting messenger RNA (mRNA) that codes for the human androgen receptor. It comprises an androgen-receptor-specific small interfering RNA (siRNA), meticulously constructed from 19 ribonucleotides. This RNA component is conjugated with a complementary DNA strand, also consisting of 19 deoxyribonucleotides, specifically selected from the isoform-common region of human androgen receptor mRNAs isoform 1. The ingredient's primary function is the effective and specific degradation of this target mRNA, aiming to reduce the cellular response to androgens.

Stability
Polyethylene glycols (PEGs), which are integral components of this ingredient, are recognized for their microbiological stability. This characteristic may inherently contribute to the formulation's resistance to microbial growth, potentially reducing the need for additional preservative systems.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has not conducted a specific safety assessment for STEARYLDISULFIDEHEXYL SH-DNA-2 PEG-45/SH-RNA-1 as a complete entity. While general information suggests polyethylene glycols (PEGs) are typically well tolerated by the skin, this generalized statement does not encompass the full safety profile of this complex, novel ingredient.
