Undaria pinnatifida is commonly called sea mustard in English, miyok in Korean, and wakame in Japanese. It is an edible brown seaweed native to and growing in East and Southeast Asia. In traditional medicine, this seaweed is well-known for blood purification and detoxification. MYFerm is a liquid fermented extract of U. pinnatifida by probiotics L. acidophilus to break down complex polymers for better penetration and absorption of active compounds into the skin. The collagen synthesis level was significantly increased when fermented.
