Science
Mechanism of Action
These lipids integrate into the skin's lipid matrix, acting as a conditioning emollient that bolsters the skin barrier. This reinforcement protects against environmental aggressors and desiccation, effectively reducing transepidermal water loss (TEWL) and promoting a smoother skin surface.

Stability
Consistent with other lipids, stability concerns typically involve hydrolytic degradation. This process is influenced by various factors, including pH, temperature, buffer composition, ionic strength, the specific acyl chain length, headgroup structure, and the overall state of aggregation within the formulation.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that there is insufficient data to support the safety of placental lipids and other placental-derived ingredients, specifically requesting further skin sensitization data at typical use concentrations. Human-derived placental ingredients are explicitly prohibited within the European Union due to serious concerns regarding the potential transmission of human spongiform encephalopathies and viral diseases such as HIV. The FDA advises that if placenta-derived ingredients are depleted of hormones and biologically active substances for safety, they should not be identified as 'placenta extract' to avoid misleading consumer expectations about biological activity. Animal-derived placental proteins, hydrolyzed proteins, lipids, and enzymes were reported to be in use at the time of the CIR report.

Verdict
Given the CIR's finding of insufficient safety data, the EU's prohibition on human-derived placental ingredients, and a lack of clinical efficacy studies, the utility of Placental Lipids in precision skincare is highly questionable.
