Science
Mechanism of Action
HPE operates by upregulating the expression of genes crucial for extracellular matrix (ECM) organization, including COL1A1 (Type I collagen), ELN (elastin), and HAS2 (hyaluronan) in dermal fibroblast cells. This promotes increased levels of key structural components. Furthermore, HPE exhibits anti-inflammatory, antimicrobial, antioxidant, and anti-apoptotic activities, contributing to improved skin elasticity, a brighter complexion through free radical neutralization and cell turnover, and diminished fine lines via enhanced collagen synthesis.

Dusting Analysis
Human Placental Extract is often 'dusted' in formulations due to its perceived potent anti-aging, regenerative, and skin-conditioning benefits, leveraging its unique and complex biological origin despite substantial safety and regulatory challenges.
The Formula
Formulation
Stability
As a sensitive biomolecule, the stability of placental extracts is best maintained within a neutral pH range (6.1-7.4) and in carefully designed formulations that may incorporate gentle humectants, stabilizers, or encapsulation systems.
Conflicts
- Strong acids, high concentrations of alcohol, and aggressive exfoliants, which can degrade protein components and alter effectiveness.
- Substances with known estrogenic or other biological activity, to avoid unintended metabolic or endocrine effects in cosmetic applications.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has determined that available data are insufficient to support the safety of human placental extracts in cosmetics, requesting further extensive toxicity and sensitization data, and noting concerns regarding potential endocrine disruption. Globally, regulatory bodies have severe reservations: the European Union prohibits human-derived ingredients, including HPE, due to the risk of transmitting human spongiform encephalopathies and viral diseases (e.g., HIV). The FDA does not recognize HPE as a cosmetic ingredient if it contains estrogenic hormones or other biologically active substances, deems it potentially hazardous, and has issued public health warnings for cosmetic products containing placenta cream.

Verdict
Due to widespread regulatory prohibitions, critically insufficient safety data, and significant concerns regarding disease transmission and potential endocrine disruption, Human Placental Extract is not deemed safe or suitable for cosmetic use.
