The Importance of Placenta Protein Extract
• Typical Benefits of Placenta
Placenta is a traditional folk medicine in many Asian cultures. It is said to have many wonderful effects, notably rejuvenating the skin, reducing wrinkles, and repairing wounds. These effects are studied in various scientific and independent researches and are mentioned in every one of the articles in our list of references and numerous others. The key reasons for such effects as cited by the articles include the increase in collagen level and the antioxidant and anti-inflammatory properties of Placenta extract.The research by CH Wu et. al. published by the National Center for Biotechnology Information, U.S. National Library of Medicine1 found that placenta extracts reduce wound healing time by 50%. Another research by Korean2 reported that placenta extracts significantly improved the water retention level of skin damaged by UVB (an ultraviolet ray that burns the skin), reduced the level of wrinkle formation, and improved collagen level. However, the same study also found that placenta extract did not significantly improve Erythema (i.e. redness of skin) caused by UVB and may slightly increase melanin (dark pigment) in damaged skin.Philia Moisturizer contains added Vitamin E to protect the skin so that it is less susceptible to UV ray damage.
• Does the Source of Placenta Matter?
There are four common sources of placenta extracts that are being used today: Human, bovine (from cows), porcine (from pigs) and ovine (from sheep). Deer placenta is also promoted by some. Based on the articles read and Google search, there are no known major differences in the documented effects of these placentas. In fact, all the articles have been cross-citing research of different placenta types, for example, a study on porcine would cite other studies using human placenta, and vice versa. This strongly suggests to us that while the sources may be different, placenta, in general, do demonstrate similar properties and effects.
• What Should Be the Dosage of Placenta?
A research by Japanese scientists in 2013 has found effects of placenta extracts on collagen secretion and facial wrinkle changes, and the effects are DOSE-DEPENDENT. The study has shown that the effect of placenta extracts peaks at around 100µg/mL.The “100+” in Philia’s Moisturiser “Active Hydration with Placenta 100+” indicates that the cream contains at least 100µg/mL of placenta extract.
