What is placenta extract, and why is it popular in Japan?

Placenta extract is one of the most distinctive ingredients in Japanese beauty supplements. Marketed for skin radiance, vitality and "beauty from within," it's far more mainstream in Japan than in many Western markets.

What to know

• What it contains: amino acids, peptides and growth factors, depending on the source and processing.
• Japan's context: injectable human-placenta pharmaceuticals have been approved and used in Japan for decades (e.g. for liver and menopausal support), which is part of why the ingredient is trusted there. Oral supplements are a separate, beauty-focused category.
• Sources: supplements typically use porcine (pig), equine, or marine placenta; "plant placenta" is a different, botanical ingredient.

Evidence for oral placenta supplements is limited, so treat the beauty claims as promising rather than proven. Neoi's PCN placenta sits in our supplement range; see also is placenta safe and NMN vs placenta.
