PLACENTAL PROTEIN

Last update on Sep 17, 2025

Placental Protein is a nutrient-packed cosmetic ingredient extracted from animal or plant placenta. It is loaded with proteins, peptides, vitamins, and antioxidants. This ingredient became a trend in Korean and Japanese skincare for its regenerative and anti-aging benefits, and has been used in the beauty industry worldwide since then. However, the use of placenta is traced back thousands of years in Chinese and Egyptian cultures for its regenerative and healing benefits. In hair care, Placental Protein is renowned for inhibiting hair loss and supporting strength. It is often combined with other ingredients such as vitamin C and hyaluronic acid for maximum benefits. It is important to note that the claimed benefits of Placental Protein have not been proven scientifically due to limited research. There is also not much research available on its safety.

Origin

Placental Protein can be derived from both plants and animals. However, plant-based Placental Protein is more common in modern cosmetics due to ethical and purity concerns. The “placenta” in plants is usually the ovule or seed tissue. The extraction takes place by placing the plant placenta in a solvent like water or ethanol. Then, the active compounds are separated and concentrated, removing plant fibers and non-active material. 


If animal-derived, the placenta is collected from sheep or cows post-partum and is thoroughly cleaned. It is then treated with solvents to break it down. The extract is purified and sterilized. Depending on the requirements, Placental Protein is available in a solution form or freeze-dried into a powder.

Safety Profile

Although limited research is available on its safety, plant-based Placental Protein is considered safe for use in cosmetics. High-purity and sterilized animal placenta extracts may also be deemed as safe, but the risks of contamination and disease transmission are high. It is also not accepted in vegan, halal, kosher, and cruelty-free formulations. Therefore, plant-derived Placental Protein is becoming increasingly the preferred option in the beauty industry. In any case, patch testing is recommended. 


Additionally, animal-based Placental Protein is strictly prohibited for use during pregnancy, but its plant-based counterpart may be used after consulting a healthcare professional.
