Science
Mechanism of Action
Placental enzymes function as signaling molecules, with specific types like heat-stable alkaline phosphatase, diamine oxidase, and oxytocinases contributing to skin renewal. They facilitate the breakdown of dead skin cells for exfoliation and stimulate the proliferation of both dermal fibroblasts and epidermal keratinocytes, enhancing overall skin turnover. Furthermore, these enzymes are known to boost collagen and elastin production, improve antioxidant enzyme gene expression (e.g., SOD-1, SOD-3, catalase), and reduce tyrosinase activity for potential skin brightening effects.

Stability
Placental enzymes are typically obtained via aqueous extraction, indicating water solubility. Their specific composition and biological efficacy are influenced by preparation methods. Certain placental ferment filtrates have demonstrated stability under high-temperature processing, specifically tolerating heat sterilization at 121 °C.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has determined that current data is insufficient to establish the safety of Placental Enzymes in cosmetics. They emphasize that any cosmetic use must be free of detectable metabolic or endocrine activity. Additional safety assessments are required, including skin sensitization, reproductive and developmental toxicity, photosensitization, genotoxicity, and ocular toxicity. Furthermore, any use must guarantee the absence of pathogenic viruses or infectious agents. The European Union prohibits human-derived ingredients in cosmetics due to disease transmission concerns, and the FDA does not recognize certain placental extracts (those with assumed hormonal activity) as cosmetic ingredients, despite reported usage.

Verdict
Despite promising in-vitro efficacy, the overall safety profile for placental enzymes is considered to have insufficient data by the CIR, coupled with significant regulatory restrictions and concerns regarding potential biological activity and disease transmission, rendering it highly questionable for cosmetic use.
