SH-DECAPEPTIDE-1 SH-OLIGOPEPTIDE-4.

No specific data is available to indicate common dusting practices or thresholds for this particular peptide combination.

The safety of SH-DECAPEPTIDE-1 SH-OLIGOPEPTIDE-4 as a combined ingredient has not been specifically evaluated by major regulatory bodies like CIR, SCCS, or FDA. While information exists for individual peptides, such as SH-Oligopeptide-1 (EGF), which is generally considered safe in cosmetics with rare adverse reactions and authorized for use, its long-term risks remain uncertain and functional bioactivity in cosmetic applications is questioned. The broader category of 'skin and connective tissue-derived proteins and peptides' has been deemed safe by CIR; however, this assessment does not specifically address the synthetic peptides in question or their combination. Sensitivity testing is generally recommended for novel cosmetic ingredients.
